A well-insulated attic prevents air from escaping the home and outside air from coming in. Before you insulate or improve the existing insulation in your attic, it is important to weed out common myths and misconceptions about it. Here, a residential roof replacement debunks three of them.
How Does Moisture Affect Your Home?
One of the main roles of a roof covering is to keep excess moisture out of the house. Too much moisture inside the living space can lead to a number of cosmetic and structural problems, and worse, increase the risk of health complications among the residents. A residential and commercial roofing expert in the area talks about how moisture damages a roof below.

Material Damage
Moisture can affect many different kinds of materials commonly found in homes. For example, in a granular material like drywall, water seeps into the spaces between the particles, reducing the strength and integrity of the material. If your drywall is sagging, it likely means that it has become saturated with water. On the other hand, cellulose-based materials like wood can begin to rot when moisture levels reach around 20 percent. Corrosion of metal fasteners is another moisture-related problem to look out for.
Comfort Levels
Too much moisture can certainly decrease the comfort of your home. If moisture from a roof leak causes your indoor air to become humid during the warmer months, your comfort level will not only be compromised but your cooling costs will also skyrocket. Do not hesitate to contact a residential roof replacement contractor to check up on your roof and attend to the cause of moisture intrusion.
Health Risks
Health is also a primary concern. Mold fungi reproduce by releasing mold spores into the indoor environment, causing health issues if they are inhaled. People with asthma, allergies, or weak immune systems can be easily affected and develop serious infections. When you see patches of mold in your attic, do not hesitate to call your local mold remediation expert to address the issue.

Factors That Affect How Well An Asphalt Roof Ages
Asphalt shingles remain the most widely used roof covering in North America, and for a good reason — they offer high performance for a lower cost. However, like other roofing materials, there will come a time when asphalt your asphalt roof will deteriorate and require roof repair or replacement. The rate at which shingles weather can depend on a number of factors:

-
Quality of the shingles. As expected, low-quality asphalt shingles will deteriorate faster than high-quality shingles. Quality can vary among manufacturers, so make sure to compare them before choosing the product to install on your roof.
-
Slope of the roof. Normally, low-slope or flat roofers have shorter lifespans than roofing systems with steeper slopes because they shed moisture more slowly and are directly exposed to solar radiation.
-
Climate of the local area. Another factor that affects how well an asphalt shingle roof ages is the local climate. Regions that frequently see harsh weather conditions can experience shorter roof lifespans. Wind, moisture and thermal cycling all contribute to the decay of residential or commercial roofing materials.
-
Ventilation in the attic. If the attic has poor or insufficient ventilation, it can cut down the life expectancy of the roofing structure. Poor ventilation fails to keep asphalt shingles cool, which ultimately leads to accelerated loss of volatiles and significant amounts of thermal cycling.
-
Color of the roof. Generally, dark-colored roofs absorb more heat than light-colored ones. Asphalt shingles in white, beige or light gray reflect more light and stay cooler in sunlight.
-
Quality of maintenance. Performing regular repair and maintenance on your asphalt shingles can extend their service life. If you fail to address problems such as leaks or rot, it should come as no surprise that the roof will fail long before its life expectancy.

Avoid Roof Stacking: Here’s Why
Many homeowners prefer to perform a re-roof or overlay because it’s significantly cheaper than a full tear-off. However, nailing new shingles over your old ones isn’t exactly the best idea. In fact, it comes with a few drawbacks, including failing to address a host of roofing issues such as leaks.

In this blog, roof repair and replacement contractor Sully-Jones Roofing reveals the reasons why installing new shingles over old ones should be avoided as much as possible.
-
It won’t address leaks. A roof overlay won’t get rid of leaks, and can even further conceal the problem due to the multiple layers of shingles sitting on your roof. Water can also seep between the layers and materialize in other spots, which makes patching difficult to carry out.
-
It will add unnecessary weight to your roof. Placing another layer of heavy shingles on your roof ultimately adds weight to the top of your house, potentially reducing its structural strength. Also, the new shingles will absorb more heat, which wears down the new shingles than if they were installed on wood sheathing.
-
It will lower the resale value of your home. Choosing a re-roof instead of a proper residential roof replacement can decrease the overall value of your home. If your roof needs to be restored and you’re planning to put your property up for sale in the near future, a complete tear-off is the better choice for optimal resale value.
-
It will eventually require a replacement. Since a roof that has been re-roofed is more susceptible to storm blow-off than a newly replaced one, you’re more likely to need your roof replaced in a few years. This means double the labor and, of course, costs.

How to Verify Your Roofer’s References
After you’ve crafted a shortlist of roofing contractors, it’s time to check your roofer’s references. All reliable contractors should be able to provide references that catalog their clients, friends, and family. However, you need to dig deeper than a few phone calls if you want to gain insight into their true character.

Sully-Jones Roofing, a trusted residential and commercial roofing company in California, shares tips for checking your contractor’s references before hiring them for a job.
-
Ask the contractor for three references from the past five years. While it’s guaranteed that the initial list will only contain satisfied customers, the information will be extremely helpful. Were they satisfied with the work? Did their project run over budget? Was the roofing team professional and courteous at all times?
-
Request three references from long-time material suppliers. The potential roofer’s financial solvency should be factored in. Ask questions that will provide clues to how the commercial or residential roof replacement contractor conducts their business behind the scenes. Simple questions to ask are “Do they pay their bills on time?” and “How long have you sold them materials?”
-
Check the contractor’s license and insurance. Confirming the license and insurance of a roofer may seem like a formality, but don’t let out-of-date documents slide. Hiring a properly licensed and sufficiently insured contractor can protect you in the event of a dispute. Good contractors have nothing to hide, so you should be able to confirm these with little or no pushback.

Why You Should Be Cautious of Low Roofing Bids
Gathering roof estimates from different contractors is a crucial part of the budget-planning process. While it’s tempting to buy into cost-cutting measures like hiring the contractor with the most low roofing bids, it may end up costing you a lot more in the long run. Sully-Jones Roofing, a reputable residential roof replacement company in the area, discusses why you should think twice before accepting a low bid.

You’ll Likely Get Low-Quality Materials
Unreliable contractors usually incorporate poor-quality materials into their estimates, hoping that the client won’t take notice, in order to come up with extremely low bids. Be sure to pay attention to the list of materials and components that will be used for the installation and don’t hesitate to voice your concern when something is unclear to you.
The Contractor May Not Have Enough Experience
It’s not uncommon for less experienced contractors to offer lower roofing bids to attract more customers. While it’s not a grave necessity to hire a roof repair or replacement contractor with decades of experience, it’s an excellent measure of their relevance, reputation and, ultimately, quality of service. With an accomplished roofing company, you’ll be working with a highly skilled staff who has access to state-of-the-art technology for your roofing project.
You May Not Get the Best Warranties
There’s a great chance that a low roofing bid won’t include coverage for costs like tear-off and disposal or workmanship warranties. Warranties protect you from issues like material defects and installation errors, both of which are costly to fix. Getting the best coverage you can is a significant investment that you shouldn’t overlook during the budget-planning period.

4 Ways to Restore a Damaged Commercial Roof
While modern-day commercial roofing systems are designed for long-term performance, they may still develop problems during their lifetimes as a result of lack of maintenance and harsh weather conditions. When you need to restore the good condition of your commercial roof, there are four options you need to consider: repair, re-cover, replace or coat.
How Is A Flat Roof Inspected?
A flat roof has specific requirements in terms of repair and maintenance. Since some roofing issues like water ponding and insufficient drainage tend to be more common in flat roofing, the guidelines for inspecting a flat roof can be different from those of standard sloped roofs.

In this article, a residential and commercial roofing expert discusses how flat roofs are inspected.
-
Clean up debris. To carry out a thorough inspection, a roofer will have to remove debris from the roof first. A clean roof makes it easier to detect problems and ensures that no area will be overlooked during the process. Without leaves and twigs collecting on the roof, the roofer can see if there is debris caught under the roofing material that can indicate a leak.
-
Check for water ponding. In many instances, the presence of small pools of rainwater on a flat roof means that there is a flaw in the design of the roofing system, usually with the drainage. Water shouldn’t be pooling on your flat roof’s surface for extended periods after a rainfall stops. When there is standing water, the roof is exposed to too much moisture, which only brings about a series of costly problems, such as leaks, mold and rot. Let a roof repair specialist address the design flaw in your flat roof to prevent the occurrence of standing water in the future.
-
Inspect the attic. An experienced roofer knows that the condition of the attic can affect the health of the entire roofing system. Along with moisture issues, they will be on the lookout for signs of insufficient ventilation. Once they’ve identified the root cause of the problem, they will carry out the necessary repair or replacement.
