Residential Roofing Costs – San Diego

What Does a New Roof Cost?

This is the number one question we get asked by customers. It is also a loaded one. We understand that customers are anxious to get right to the bottom line but there are many factors that will determine the cost of your new roof.

Before we can give you a quote, Sully-Jones Roofing does a complete roof inspection, taking into consideration the condition of the existing roof, flashings, drains, gutters, solar panels, skylights and underlying deck. Once we can assess the current state of the roof, we can help you determine whether it makes sense to repair, re-cover or whether a complete roof replacement is required.


New Roof Cost Factors

Preparation – A professional roofing company will remove the existing shingles, tiles or flat roofing materials to further assess the condition of the plywood, flashing, drains, gutters, roof penetrations such as skylights and seals. Once removed, the roofing company will properly dispose of all debris. New roof preparation is normally estimated by the square foot.

The Materials – Like any remodeling project, there are a wide variety of materials, all at a wide variety of price points. Not only will the materials you choose be a significant factor, the size of the roof will determine the amount of materials and labor required.

Whether you are choosing a tile roof, a shingle roof or have a flat roof, you have options – many, many options. You may think that all tile roofs are approximately the same, but there are numerous variations in style, durability and cost. See our Tile Roofs page to see just a sample of the styles available to you. Shingle roofs present an even greater variety of styles, colors, and quality levels – see the Shingle Roofs page to see just some samples of your choices. And you may be surprised by the array of offerings for Flat Roofs. Sully-Jones installs all major brands and types of roof materials. Our experts can help to guide you through the wide variety of choices to find the perfect fit for you home and your budget.

The Bottom Line

While we can’t give you an exact cost until we have inspected the condition of your roof, you have selected the roofing materials and we have calculated the square footage, we can give you a broad range based on the type of roof you may need. Below are some ranges – though we have installed roofs in these categories that have come in above or below these ranges based on a variety of factors.

Commercial Roofing San Diego – Recover or Replace?

WhiteRoofCropSan Diego’s building owners and facility management executives know that with regular inspections and roof maintenance, their commercial roofing systems can protect their buildings for decades – but eventually, there comes a time when even a well maintained roof will need to be replaced.

So how do you know whether you need to replace your commercial roof, or can repair or recover?

The first step to determining how much more life you can get out of your existing commercial roof is to have a roofing professional conduct a careful, detailed evaluation of your existing roof. They will take into consideration the weather/climate implications of your geographic region, the age of the existing roof, impacts on business activities, and your long-term plans for the building your roof is protecting. Then they will inspect for damage to your roofing membrane, insulation and roof decking.

 A Roofing Professional Will Inspect for:

  • Moisture infiltration and resulting damage
  • Slippage, movement or splitting of the roofing membrane
  • Age, overall condition and pliability of the roof membrane
  • Structure integrity of the roof decking


Whether you plan to repair, recover or replace your commercial roof, an inspection for the presence of moisture below the roofing membrane is critical. Your roof inspector will ask about previous incidences and severity of roof leaks. They will closely inspect the roof for any evidence of moisture. The membrane may appear to be in good condition on the surface but there may be the presence of moisture below the roofing membrane. Whether from tears or penetrations of the membrane itself or from other sources, moisture will create problems that compromise the integrity of the roof. Wet insulation, wood blocking and gypsum will deteriorate the roofing membrane, cause structural damage to the roof deck and may lead to further problems, such as mold growth and expensive mold remediation.

If the subsurface moisture is extensive, 30 to 35 percent or more of the entire roof area, it may be more practical and cost effective to remove the entire roof system and replace it rather than attempting to recover. If the areas affected are somewhat isolated, you may be able to put off a complete roof replacement but all wet insulation and materials must be removed and replaced prior to repairing or recovering an existing roof.


Another determining factor that will influence your decision to recover or reroof is the roof cover’s ability to withstand the uplift pressures associated with severe wind. Roof cover performance can be measured by conducting an uplift test in the field, perimeter, and on corners of the roof.

Uplift tests are useful to help determine a roof cover’s ability to stay intact during severe winds. Though the roof may look like it has weathered the storm, a time or two, exposure to uplift forces could weaken the roofs ability to resist uplift pressures during the next big storm.

Local building codes provide the minimum acceptable standards for roof strength. While a roof cover system may have 20 year warranty, often consumers are not aware that most roof warranties will not cover damages as a result of named storms, wind speeds over 74 mph (or sometimes less), wind damage, acts of God, hail, etc. Conditions where the warranty is voided are typically listed in the “Exclusions” part of the warranty. If damage is caused by any of the exclusions listed, the building owner’s deductible and insurance company may not cover the cost to repair or replace the roof cover. Some companies do offer warranties that include windstorm damage, but it is not standard practice and will often cost extra.

Should your roof qualify for a roof repair or recover, the project should include securing existing roof cover to the deck below before recovering.

 Age and Condition of the Roof System

Another factor influencing whether or not a recover project is feasible is establishing how many roof systems or layers are currently in place, which requires making inspection openings. Most modern building codes allow a maximum of two non-ballasted roof systems on a structure, mostly due to the weight associated with the roofing materials. Other code-related issues include fire resistance, which the building’s insurance carrier may also influence through specific requirements.

The length of the warranty required for the new roof also needs to be considered, because many roofing material manufacturers will limit the duration for the warranty available on recover projects. Commercial Roofing Contractors will often offer warranties on workmanship and extended warranties on materials. See Sully-Jones Extended Warranty.

 Roof Decking

When considering whether to recover or re-roof your commercial roofing system, it is critical to have the roof decking system inspected. If significant damage to the decking is found, you will have no choice but to tear off and re-roof.

Recovering Pros and Cons

Cons – There is a risk of trapping moisture beneath the new roofing surface, which will continue to deteriorate insulation and roof decking. Trapped moisture can also lead to mold and costly mold remediation.

Pros – Recovering is less expensive than roof replacement. There are no tear-off and disposal fees. Recovering can help you extend the life and cost effectiveness of your existing roof. See our post about flat roof covering options. 

Replacement Pros and Cons

Cons – Costs are higher than roof repair or recovering. It will take longer to complete the work.

Pros – There have been many advancements made in roofing materials. You will have a completely new roof that complies with current building codes and will stand the test of time – often longer than the warranty.

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.


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.
