The 8 Most Common Reasons Your Flat Roof Could Fail Prematurely

 The Good, the Bad and the Ugly Truths About Your Commercial Roofing System

The Good – When kept clean of trash and debris, along with proper maintenance, your flat roofing system can last significantly longer than its original warranty.

 The Bad – Because flat and low-slope roof systems serve more purposes than simply protecting the building beneath them, they are more prone to premature deterioration than a sloped roof.

 The Ugly – Below you can read about ten of the most common and sometimes ugly sources of problems that lead to premature commercial roof deterioration.

As a roof ages, some problems are inevitable, but if you know what to look for, you will be able to prevent conditions that can lead to expensive commercial roof repairs or premature roof replacement.

Ponding Water Page Best


No matter what type of roof you have, leaks can happen and when they do, they can significantly damage the roof structure, the building and the contents within the building, unless quickly identified and repaired. There are many sources of leaks, especially on commercial flat roofs – not always originating with the roof itself.

Most leaks on BUR flat roof systems originate at flashings (where the roof membrane is terminated or interrupted).

Hot asphalt and torch-applied modified bitumen roofs may experience leaks when a proper moisture barrier is not installed underneath edge metal and wall copings.

When single-ply membrane roofs are installed with poor seams, leaks can occur. The membranes themselves will hold water, however improperly sealed seams can leak. Proper procedure for your professional roofing company is to check every inch of lap with a probe at the end of each day in order to assure there are absolutely no voids.


A faulty installation dramatically increases the likelihood of problems and reduces a roof system’s life expectancy. Problems with adhesion can result when the area isn’t cleaned, dried, and primed properly prior to installation. These are the types of problems that are difficult to see but could lead to future problems, accelerated aging, or premature failure.

Material preparation is important to a quality installation. Torch-applied mod bit system performance can be compromised if crews do not relax the sheets prior to installation, resulting in blistering, wrinkles, fish mouths, and leaks. Always hire a professional roofing company that is experienced at installing the particular type of roof system you are planning to use on your buildings.


Flashing that is not attached correctly will not only be a source for leaks, open seams and laps will ultimately cause blow-offs, reduced puncture resistance, and code issues, advises C.A.R.E.

Poor gravel embedment and an inadequate number of fasteners in the base sheet during application of both hot bituminous and torch-applied mod bit roof systems can also cause uplifts and blow-offs.

To prevent wind uplift, seams made with cold adhesives must be cured adequately to insure their integrity on cold-applied mod bit roof systems. If the seams are exposed to wind or rain before they are properly cured, moisture can infiltrate the roof system or wind uplift can damage the roof membrane.

Single-ply roofs can also be at risk for blow-off and billowing if not adhered properly to the substrate.


It is never a good idea to let water accumulate on your roof. Before roof repairs are hastily ordered, the source of the ponding water should be thoroughly investigated. A rule of thumb in the roofing industry is “ponding water should not remain on the roof over 48 hours”. Ponding water can be reduced by either adding additional drains, re-sloping the substrate, or in certain cases the substrate can be leveled by adding cement based leveling material.


Foot traffic by tradesmen, construction on the roof or installation of equipment after the roof is installed can cause punctures or tears. YOur commercial roof systems’ performance is compromised when new equipment and penetrations are added to an existing roof, unless proper precautions are taken. In addition to leaks, damage caused by foot traffic can cause deterioration of the roof membrane and may void the warranty. It is a good idea to limit traffic and conduct inspections after tradespeople have been on the roof.


Tenant improvements (TI) either authorized or unauthorized by the building owner or manager is a major concern unless a professional roofing contractor is involved. Many contractors keep their costs lower by utilizing unlicensed roofer or one of their laborers to seal around new roof penetrations. This situation generally produces a leaky roof.


It is critical that the correct materials for roof repairs are used. Using materials that are not intended for application on your specific roof type can result in permanent damage to the roof. Follow the manufacturer’s instructions for proper use and take note of repair products with a shelf life.


All roofs and rain gutters should be clear of leaves, trash and debris a minimum of once per year. A roof inspection should be performed at the same time with a report to the owner or property manager to give them the information they need to head off problems. Being wise to problems can prevent their escalation.



Commercial Roof Repair and Maintenance San Diego, CA

Should Property Managers Perform Their Own Commercial Roof Maintenance?

Your roof is your commercial building’s first line of defense from nature’s elements such as wind, rain, fire, hail, and the sun’s damaging rays. Every day, your roof is exposed to weather and other elements that may contribute to its decay and deterioration, increasing the risk of damage to the roof itself and if left unattended, to your commercial building and the contents within it.

 The International Building Code (IBC), which sets safety standards for commercial buildings, requires that roofs “serve to protect the building.” Having a roof that “protects the building” starts with design, materials selection, and installation at the time a facility is built or remodeled—events that occur infrequently and may be outside the scope of most businesses’ ongoing activity. But it also includes a regular program of inspection, maintenance, and repair—activities that should be part of your operational planning in order to prolong the useful life of your roof and make sure it does its job in protecting your business from weather damage. *Source: Insurance Institute for Business and Home Safety

Savvy property owners and property managers understand the need to protect the investment they have in their roofing systems with a regular maintenance program. A Roof Maintenance Program not only adds years to the life of your roof, it will also uncover problems before roof leaks can damage insulation, create mold, damage the structure itself or the contents within the building.

Considering Doing Your Own Commercial Roof Maintenance?

Is Roof Maintenance something that your business can do in-house or do you need to hire a professional roofing company? Below are some things to consider before establishing a proactive commercial roof maintenance program.

Annual or Semi-Annual Roof Maintenance Should Include:

  • Inspection of the entire roof membrane and roof components.
  • Cleaning of leaves, trash and debris from the roof, rain, gutters and drains.
  • Disposal of rooftop debris including nails, fasteners, bottles etc.
  • Inspections and recommended repairs for:
    • Cracked or broken skylight lens or frames
    • Unauthorized roof penetrations
    • Damaged or missing rain gutters, collector boxes or downspouts
    • Sheet metal joints on air conditioning ducts that are not sealed
    • Oil/grease overspills from exhaust hood fans
    • Missing vent caps
    • Damage caused by cable, satellite, cell site, plumbing, HVAC contractors, tenants, maintenance personnel, installers, repairmen, etc.
    • Storm damage since last inspection
    • Plugged roof drain lines
    • Damaged or unsafe roof access hatches or ladders

Check Your Insurance Policy

Insurance policies vary so before you send your maintenance personnel up to your roof, be sure that your insurance policy will cover them in case of injury or inadvertent damage to the roof.

Expertise & Equipment Needed to Address Problems

While building maintenance personnel may have the skills to make temporary repairs, they do not always have the expertise, equipment or materials to make significant repairs to the roofing system itself. It is inadvisable to make major repairs to your roofing system without first consulting a qualified contractor or roofing company. You will also want to make sure that you have the proper safety equipment while making the repairs. Sending an untrained employee to patch a roof during a rainstorm can be dangerous and may end up voiding a manufacturer’s warranty.

Problems with an aging roof can include punctured, cracked, wrinkled membranes that are losing their waterproof integrity. Roofs cements, coatings and trowel grade products can provide quick fixes but a professional roofing contractor will be able to advise you on the best long-term solution. For example, inexperienced maintenance personnel could easily make the mistake of using asphalt-based patching materials on a PVC thermoplastic membrane, which will cause further damage to the roof.

Start-Up Costs to Do Your Own Roof Management

How Commercial Roof Maintenance Pays Off

Commercial Roof Maintenance San Diego

It is not uncommon for property managers and owners to defer roof maintenance until there is a problem. This is especially true here, in sunny San Diego, CA. Even without the severe weather experienced in other parts of the country, this “out of sight, out of mind” attitude toward roofing systems can cost thousands of dollars for San Diego commercial building owners and property management companies – and is simply poor asset management. Your commercial roof may represent as little as 10% of your building’s total cost but could be 90% of your problems if not properly maintained.

Your Commercial Roof is a Fixed Asset

HVAC and Plenum Joint RepairYour commercial roof is a valuable asset that protects your building, its occupants and its contents such as merchandise and expensive computer or specialty equipment. Small problems that are not quickly repaired can result in big problems and even bigger costs down the road.

The Single Biggest Reason for Premature Roof Deterioration

Not having a commercial roof maintenance program is the top reason that roofs deteriorate before they should, often leading to leaks that cause major damage to the building and its contents.

Too many San Diego owners and property managers have experienced the pain and costs associated with deteriorating roofs resulting from exposure to sun, water, severe weather and other sources of leaks. Built up debris on the roof and improper drainage can cause ponding water and damage to the membrane of your roof and the insulation below it.  Loose or damaged fittings around HVAC and other equipment on your low-slope or flat roof will allow water to seep into the roof system. Even very small holes or punctures, often caused by personnel on the roof other than your roofing contractor, can allow a large amount of water in to damage the structure.

When water starts entering your commercial buildings, hard assets and corporate profits take a hit. When you compare the costs of major repairs or roof replacement to annual maintenance, it just makes sense that the longer you can extend the life of your current roof, the more your overall savings will increase. A proactive commercial roof maintenance program makes perfect fiscal sense.

Premature Roof Failure Costs Add Up

Estimated Roofing Costs (will vary depending on roof type, materials, installation, etc.)

New Construction Roof $2.00 – $3.00 per square foot
Tear Off and Install a New Roof $3.50 – $4.50 per square foot
Wood Deck Replacement $1.50 per square foot
Steel Deck Replacement $3.50 per square foot
Recover Over an Old Roof $2.50 – $3.50 per square foot

Even before your roof needs replacement, emergency leak repair can average about $750 per occurrence. The older your roof, the more you can expect to have roof leaks. Your costs may be negligible in the first 5 years but quickly add up in later years when a roof is not properly maintained. Should the worst happen and major leaks damage the insulation and decking, the replacement cost could double.

Add on Costs for Wasted Energy

A leak that affects even just a small area can have significant effects on your energy bills. Since wet insulation does not perform well, energy expended to heat or cool your building will be compromised. Consider what effect several hundred or a thousand square feet of un-insulated roof area would have on your monthly energy bill? We will address potential energy savings with a “Cool Roof” coatings and maintenance in a future blog post.

Structural Damage Can Be a Safety Issue

Water absorbed into insulation can add significant weight gain and corrosion of structural components can become a safety issue.

Consider the ALL of the Costs

To fully understand the benefits of a roof maintenance program, consider all of the costs associated with significant damage to your commercial roof:

  • Costs of water damage cleanup
  • Damage to merchandise and inventory
  • Damage to building interiors, including furnishings & fixtures
  • Damage to equipment such as computers, electrical, specialty equipment
  • Costs from interruption to your business and lost use of space
  • Impact on building occupants exposure to air quality, mold, etc.
  • Costs of legal claims for slip & fall accidents
  • Costs of energy loss through wet and damp roof insulation
  • Higher insurance premiums due to more frequent claims arising from water damage
  • Costs of premature roof replacement

The industry average costs for a roof maintenance program is approximately 0.03 per sq. ft. per year compared to 0.15 per sq. ft. per year for roofs without a maintenance program.

When Is The Best Time To Get Roof Work Done?

The answer is simple. NOW!  

Because we live in sunny Southern California, many people take the weather for granted and do not address the condition of their roofs until it is too late.  While we don’t have to worry about snow or ice on the roof, winter rain can seep through the roof and cause significant damage to the structure of your building and all of the contents that are supposed to be protected by the roof.  As you will see from the video below, we can’t always predict when the rainy season will start.

Don’t wait until roof leaks damage the structure of your home or commercial building.

While the weather outside is delightful, right now –  the rainy season is coming. Once the rain comes, the damage to your roof will get worse and the resulting damage to the actual structure of your home or building will get more expensive. Watch the video below to see why you should get a

Save Money by Getting Your Roof Work Done this Fall.

Spring is designated that time of year to work on the interior of your home with “Spring Cleaning.”  The fall season should be designated for time for home maintenance and improvement projects, particularly on the exterior of your home. Why, you ask? While home repairs may cut into your football viewing schedule, the weather is often at its most agreeable – the summer heat is gone and winter weather has not yet arrived. While we don’t have snow or ice in San Diego, we do get wet, windy and often cold weather that can affect the soundness of your home.  Some projects just shouldn’t be put off. One of the most important home improvement projects is the repair or replacement of a damaged roof.  If your roof has any damage or leaks, these could get substantially worse when winter weather comes. As anyone in construction will tell you, if you don’t make the repairs early, they will cost you far more later.  And since your roof covers and protects your entire house – if your roof is not in good shape, the entire structure of your home could be at risk.

Roof Repair and Replacement Can Take Less Time When Weather Is Not a Factor.

Fall is typically the busiest time of year for roofing companies – even in San Diego. Summer heat and summer vacations are over. And homeowners begin to think about winter weather and what might happen if they don’t fix the damage to their roof. Though most roofing companies are busy in the fall season, it does not mean that you will pay more. In fact, you could be paying less than if you wait.

Weather can impact the amount of time a roofing company needs to spend repairing or replacing your roof. Wet weather and wind means that your roof needs additional protection while the work is being done. If weather conditions are not good, the roofing company may remove oonly the portion of the roof that they can finish in that given day. Severe, wet winter conditions could prevent work from getting done resulting in frustrating delays finishing your roofing project. The more time your roofing company spends on your roof repair or replacement due to weather conditions, the more you are likely to pay.

Damage to Your Roof Has Probably Gotten Worse By Spring.

In addition, fixing up the roof in the fall ensures those winter storms won’t find their way into your home via leaks. Addressing leaks in the fall can prevent damage to your home’s interior when rain seeps through the roof. Water that makes its way into your home through a damaged roof will certainly cause damage to the substructure of your roof . Water can also cause mold and water damage to support structures, flooring and your belongings inside. Costs for water damage to your home can mount up quickly if a leaky roof is not addressed immediately.


What You Need To Know About Shingle Roofs For Your Southern CA Home.

Shingle Roofing Southern California

If you are planning a renovation or building a new home from the ground up, you have many choices when it comes to your roof. In Southern California, we don’t typically have to worry about extreme weather but you will want to consider how your roof will look with the architectural style of your home and of course, how it fits into your budget.  New technologies and innovations in shingle roofing have extended the lifespan of a typical residential roof and make it possible to get any look you want for your home, at a reasonable price

Residential Roofing | San Diego Roofer Asphalt/Fiberglass Shingles are today’s most popular roofing material. Not only are they less costly than wood shake or shingle roofs, tile, slate or metal roofs, but, in southern California, where summer fires are not uncommon, they offer excellent protection for your home. With an abundance of color and style choices, Asphalt and Fiberglass Shingles add to the beauty and durability of your home.

Asphalt/Fiberglass Shingles are made of a woven fiberglass base mat, that is covered with a waterproof asphalt coating, then surfaced with ceramic granules that make the product fire resistant and protect your roof from harmful UV rays. The fiberglass mat composition gives the shingles their durability and strength.

Two Asphalt/Fiberglass Shingle Types are Three Tab Shingles and Architectural Shingles.

Shake 20 Autumn Brown

Three-Tab- Shingles are the still the most economical type of shingle for your home.  These shingle roofs are distinguished by the cut-out tabs exposed along the lower edge of the shingle which gives them a nicely layered effect. See more Three-Tab Shingle Roofing examples on our website.


Architectural Shingle Roof San Diego CA

Architectural Asphalt Shingles do not have cut-outs but their lower edge is laminated with an additional asphalt layer which gives these shingles a contoured, dimensional appearance.  See more examples of Architectural Shingle Roofing examples on our websites.



Both 3-Tab Shingles and laminated Architectural Shingles contain a strip of factory-applied adhesive that is activated by the sun’s heat after installation and seals each shingle to the next. The seal strip also provides much of a shingle’s resistance to wind uplift.

How to Decide With So Many Shingle Roof Choices?

With over a dozen reputable manufacturers in North America and a plethora of color and style choices, it is often hard to tell whether a roof is shingle or wood shake or even slate. There is a shingle roof material to suite the style of any home. Get expert guidance from a professional roofing company who can walk you through the many choices from all of the top shingle roof manufacturers.

Most Common Questions About Roof Replacement and Repair

San Diego’s Leading Residential Roofing Company Answers Your Questions About Roof Repair and Replacement.

With over 60 years in the roofing industry in San Diego County, we have heard almost every question there is about roofing from our customers. Below are some of the most common questions about residential roof repair and replacement.

Roof Repair or Replacement

How Long Does It Take for a Roof Repair?

The length of time required to properly repair your roof depends on a lot of factors, primarily how much damage your roof has and the total square footage. If you only need to repair a relatively small part of the roof, the job may be completed very quickly. Even if you need extensive roof repair work, it could be done in several days depending on the size of roof. If you have a large home or extensive damage to the structure, it might take a few weeks to finish the project. Your contractor should give you a timeline for your roof repair or replacement after a full inspection, and should keep you informed if there are any changes to the expected completion date as work begins.

How Long Does It Take for a Full Roof Replacement?

Again, the timeline for your roof replacement is largely guided by the condition of your roof. For instance, when there is structural damage underneath the roof material, additional repair work will be needed – you should not put new tiles or shingles over core building damage because the new roof will not be structurally sound. The more work that needs to be done to get the structure of your home prepared for the new roof, the longer the project is likely to take. You may not be able to see the structural damage just by looking at the roof. The only way to tell if there is damage to the structure itself, and not just the roofing materials, is to have a full inspection by a professional roofing company.

How much damage can a typical roofing contractor handle?

Some roofing contractors will only be qualified to work only on the roof itself and not on the underlying structure.  If you suspect that you have extensive damage to your roof or structural damage, you should check references to be certain that you employ a roofing company that has a track record in complete roof replacement or new roof construction.  Your professional roofing company should the equipment and experience to handle a variety of roof damage, from natural disaster aftermath to a dilapidated roof resulting from wear over time.

What happens to all the debris?

Your roofing contractor will take away the debris that results from your re-roofing project. Depending on your city’s regulations, it may not be legal to throw certain debris into the trash. For residential roofing in San Diego, CA, while you are allowed to send your materials to the landfill, it’s recommended that you recycle as much of the material as is possible. California is already experiencing an overflow of construction materials in its landfills. You should not be responsible for the disposal, however. Your roofing contractor can bring a large dumpster to store debris until it’s ready to be removed from your property. Make sure that debris removal is included in your roof repair or replacement bid.

What happens if it rains during my roof replacement?

Your roofing contractor should always check the weather report to see if rain is in the forecast. If it does rain, it’s in your best interest to postpone work until the work can commence in dry conditions. In the mean time, your roof should be protected so that it’s water-tight. This can be accomplished by applying paper and tarp over the part of the roof that is currently exposed with no shingles or tiles. Any experienced roofing company will make sure that your home is protected from weather while working on your roof repair or replacement.

Typical costs

Costs associated with a roof repair or replacement include; materials, labor, and disposal fees. The cost of a total replacement can vary between a few thousand dollars, or in excess of $10,000 depending on the roof materials you choose and the size of your roof. Your roofing contractor should provide an itemized estimate for the project in writing, so you will know what the project will cost before work begins. Ask for any updates regarding new fees or unanticipated expenses that pop up during the project. You will usually be asked to pay at least part of the bill before the project begins, so that your contractor can purchase the necessary supplies.

Will Insurance Cover Roof Repair or Replacement?

Answers to Your Roofing Questions from San Diego’s Leading Roofing Company.

One of the most common questions we get from customers is “Will my insurance cover the cost of my roof replacement or repair?”

Insurance Coverage for Roof Repair and Roof Replacement

Sully-Jones Roofing provides FREE roof inspections and estimates for insurance claims.

In the event that your roof experiences some sort of damage, whether it’s from a hail or wind storm or a misguided firecracker, you should fix the bad shingles or tiles as soon as possible. A damaged section of roof can lead to flooding, pests, and wasted energy. Even if you do not see visible damage, but your roof has outlived its warranty, you should get an inspection of your roof.  Fortunately, if you have homeowners insurance, the burden of paying for roof repairs or replacement usually does not fall completely on your shoulders. Your roofing contractor should be able to help you navigate your way through the roof insurance claims process.

Will Insurance Cover a NEW Roof?

Whether or not your insurance covers the cost of roof replacement depends largely on the extent of the damage. When roof repair could resolve the issue, your insurance company will want to fix the damage with less costly and less extensive repair measures. The cause of the damage is also considered when your insurance decides whether or not to replace the roof under your policy. If your roof has sustained damage from something unexpected, such as a fallen tree or a fire, chances are that they will cover a full replacement if the damage is severe enough. If the roof is older than the roof warranty, insurance may not cover roof replacement. Sully-Jones Roofing will be happy to come out for a full roof inspection and provide you with the information your insurance company will need to assess whether a new roof will be covered.

Will Insurance Fully Cover Roof Repair?

If the damage caused to your roof is caused by a natural disaster or accident that is covered by your policy, you should be able to get all repairs paid for by your policy. On the other hand, excluded circumstances won’t be covered. For instance, Named Peril Insurance will only cover the cost of repairs that are specifically named in the policy,which usually includes things like lightening and hail damage. On the other hand, All Risk Policies will cover everything except for those types of damage that are specifically excluded. For example, tree damage, random debris falling from the sky and broken shingles from a rogue firework should all be covered by an All Risk Insurance policy unless your policy names them as exceptions.

Does the Age and Condition of the Roof Affect Insurance Coverage?

Your policy may outline age requirements for roof replacement or repair. For instance, if your roof is more than 10 years old, you may only be allowed reimbursement for the depreciated value of your roof instead of the original value. As aforementioned, the condition of your roof also matters when the insurance company evaluates whether or not it can cover your roof damage. The more severe the leaking and evident damage that is present, the better your case for the necessity of a repair or replacement.

What are the General Guidelines for Filing a Claim For Roof Work?

Before you can get work done on your roof that will be covered by insurance, you will need to get an estimate from a professional roofing contractor.  In most cases, you are allowed to use the roofing company of your choice. You can also file a supplemental claim if the roof ends up costing more than the original quote.

Even in sunny San Diego, residential roofs will naturally deteriorate over time. In addition, extreme weather and accidents, can play a part in its roof damage. Reading the fine print of your insurance policy when the roof is in good condition will help you file a claim more smoothly when the time comes that your roof needs to be repaired or replaced. Sully-Jones Roofing has extensive experience in providing roof estimates for insurance claims and helping our clients navigate the process of getting their roof repair or replacement covered by their insurance company.

Commercial Roofing for Shopping Malls Requires Specialized Service.

Roof Replacement for Shopping Centers can present its own sets of issues and obstacles to overcome. There are many reasons why shopping mall owners and managers should use a Commercial Roofing Company specifically experienced in repairing, replacing and maintaining shopping mall roofs.

As a commercial property owner or manager, you know that your tenants and their customers do not want to be disturbed by your roof repair or replacement.  They don’t want workers stomping on their roof during shopping hours. They don’t want to deal with the debris that comes with re-roofing and repair.  But while the process of repairing or replacing your shopping mall roof could be a disruption, your tenants certainly don’t want roof leaks to damage their merchandise or interfere with their business.

Repairing, replacing and maintaining your shopping mall roof is essential, so you need to work with a Commercial Roofing Company that knows how to minimize disruptions to your tenants. Sully-Jones Roofing, serving San Diego County, CA has over 60 years experience in roofing and an extensive list of shopping mall roof installation, repair and maintenance customers.

Shopping Mall Roof Requires Specialized Roofing Company

A Recent Shopping Mall Roof Replacement Project

Sully-Jones Roofing, San Diego, CA recently installed a new roof on the GTM Shopping Center in Lemon Grove – home to the GTM General Store, Joanne’s Fabrics and Cotijas Mexican Restaurant.  The parking lot, at this particular mall, is packed with customers 7 days a week.  Sully-Jones worked with GTM Property Management to perform the work with the least amount of disruption to the tenant businesses.

The old roof was installed by Sully-Jones many years ago and was ready to be replaced. GTM was happy with the work Sully-Jones did on their previous roof and selected them again for the new work on their shopping mall roof.

Before Sully-Jones Roofing could install the Polara® polyester built-up commercial roof, over 43,000 square feet on two buildings, they had to remove multiple layers of roofing – totaling a whopping 344,000 pounds (172 tons) of debris.   They also had to correct drainage problems and replace roof drains.

Sully-Jones recommended the Polara® polyester built-up commercial roof for GTM because it’s non-woven, needle-punched, and heat-resistant polyester meets the exacting technical requirements of the built-up roofing (BUR) industry and is far superior in water tightness and puncture resistance.

Prolong the Life of Your Shopping Mall Roof with a Protection Plus Roof Warranty

GTM understands the importance of regular roof maintenance in increasing the longevity of their roof, so they opted for the Protection Plus 20-year Warranty Program.  The Protection Plus Program incudes annual roof cleanings to remove trash and debris, inspections of all roofing and mechanical equipment on the roof, as well as annual touch-up of roof details. The Protection Plus Warranty assures commercial customers that their roof will be protected against damaging leaks.

5 Reasons You Should Hire a Professional Roofing Company to Repair Your Roof.

Roof repair in San Diego might seem like a job you could tackle yourself. But when you stop to consider the investment you have in your roof and how important it is to protecting your home, as well as, all that you own inside your home, you will want to make sure that the job is done right. Below are 5 reasons why you should hire a professional roofing company to repair your roof.

Residential Roof Maintenance | San Diego

Reason #1: Save Money

Yes, you could SAVE money when you hire a professional roofing company to fix your roof.  Roofing companies can usually get roofing materials at a lower cost than you can. They also have all of the tools needed to complete the job correctly. When you consider the cost of purchasing all of the tools needed, you will find that the costs quickly add up.  And if you run into problems, and most do when attempting a technical job for the first time, your costs can get out of hand.

Reason #2: Access to High Quality Materials

Roofing materials are not all created equal. Your professional roofing contractor knows which materials are the best quality and the best fit for your particular roof. When purchasing roofing materials on your own, you are limited to only those materials that are available at home improvement stores. Professional roofers, on the other hand, have access to high quality materials at wholesale prices.

Reason #3: Don’t Be Left Exposed

You’re busy. Finding time to devote to repairing your roof is difficult. If you are not able to find large blocks of time to complete the entire job, you could leave parts of your roof exposed. In doing so, you will risk the integrity of your roof and expose the contents below to the elements. A professional roofing company has the experience, the tools and the personnel to get your roof repair done quickly.

Reason #4: Protect Your Safety

It goes without saying that working on a roof is an inherently dangerous job. This is particularly true when you do not have experience and all of the safety tools and equipment. If you have ever tried hauling heavy or bulky materials up a ladder, you know how precarious it can be.  Then, of course, there is always the risk of falling off the roof and seriously hurting yourself.  An average of 136,118 people every year – 49.5 per 100,000 people in the United States – are rushed to emergency rooms for ladder related injuries.

Reason #5: Warrantee on Workmanship

Professional Roofing Companies in San Diego should offer a warrantee on workmanship.  If there are any problems with the work the done on your roof, your professional roofing company will make repairs until the problem is corrected.

Standard warranties on workmanship are 1-5 years.  Sully-Jones offers labor warranties up to 20 years on both shingle and flat roofing.

Sully-Jones has the longevity, knowledge, and experience that enable us to offer these extended warranties. Our craftsmanship and installation techniques have proven the test of time and we stand firmly behind all of our work.
