Manufacturer Spotlight: CertainTeed Shingles

Andrews Roofing can supply products from any manufacturer a customer desires. However, based on our extensive experience with roofing products, there are certain ones we recommend. One of those products is the Landmark® line of CertainTeed asphalt shingles. Please note that product availability industry-wide has varied greatly between manufacturers including CertainTeed.

The quality of the products we install is the most critical factor in our recommendations, however, we also have to balance that with budget and variety. CertainTeed asphalt shingles check all of these boxes, which is why they are one of the most popular materials we install.

The Landmark® line of shingles is made with a dual-layer design that creates the visual dimension to mimic true wood shake. These shingles are heavy weight and come in a wide variety of colors. In our residential roofing portfolio, you can see many homes that have been reroofed using the Landmark® shingles, and get a feel for how varied the colors and styles can be. Of course, CertainTeed manufactures many home building products, so homeowners who are building new construction or doing a major exterior renovation can coordinate their roofing materials with CertainTeed trim, siding, decking, fencing and more.

One of the things we appreciate about the Landmark® product is the attention they’ve given to the installation process. Their proprietary design provides a nailing area that is three times wider than a typical laminate shingle, which increases the efficiency and accuracy of installation. The shingles are also made with a specially formulated adhesive that is resistant to delamination, giving these products longevity and durability.

Roofs in Hampton Roads are apt to staining thanks to our hot, humid weather that fosters mildew and algae growth. To combat this, CertainTeed uses a technology on their shingles that repels algae with a granular blend of algae-resistant copper. This means your roof maintains its curb appeal and is less susceptible to deterioration caused by organic material that could otherwise cling to an asphalt shingle.

Finally, we appreciate a manufacturer who stands behind their product. Certainteed products come with a lifetime, limited transferable warranty. This includes a 10-year SureStart™ warranty (100% replacement and labor costs due to manufacturing defects), a 10-year StreakFighter® warranty against streaking and discoloration caused by airborne algae and a 15-year, 110 mph wind-resistance warranty. Customers can also choose to upgrade their wind warranty to 130 mph. This option is especially important for our customers along the oceanfront of Virginia Beach when hurricanes move into the region. It’s also important to keep in mind that manufacturer warranties are only valid if they are installed correctly by a licensed roofing contractor.

If you live in the Tidewater region, are ready to reroof your home, and need help choosing the right product for you, please contact Andrews Roofing. We’d be happy to discuss all the available options with you and help you make an informed decision based on our decades of experience in the roofing industry.

How Warm Weather Affects Flat Roofs

Your building relies on the structural integrity of your roof. When it comes to roof damage, most building owners worry about extreme storm systems or snowy winters. Few regard summer as a problem to their roofing, which is a mistake. Hot summer days can negatively affect your flat roof. Here is what you need to know about warm weather and the affects it has on your roof.

Thermal Cycle Problems

In the summer, the temperatures rotate between hot and cold throughout the day and night. Flat style roofs expand and contract in these conditions. This usually leads to water penetrating the roof. You may need breathable PVC material to withstand the condensation and the thermal cycles.

Blistering Issues

When water penetrates through the roof, this is a problem on its own. It only gets worse when you add the summer heat into the mix. When you heat the moisture under the sun all day, it can lift the felt from the roof. This will lead to bubbles or blisters in the roof. If you catch these blisters as soon as possible, then you can replace the damaged sections. However, as time goes on and more blisters develop, you would need to replace the entire roof.

Moisture Damage

When moisture builds up, mold and fungus might grow. When you add sunlight into the mix, the high temperatures can help increase the rate of mold growth. This fungus may damage flashing. If you have damaged flashing, this compromises your draining capacity.

Older roofs and those that endure high temperatures should have regular inspections. When you have a roofing issue, you never want to wait around on it. Most roofing problems get worse with time, whereas maintenance may be simple and quick. With a call to Andrews Roofing today, you can avoid turning those minor problems into major problems.

5 Factors That Affect the Lifespan of Your Commercial Roof

While the life expectancy of a commercial roof is anywhere from 10 to 40 years, there are several factors that can affect how long it lasts. Pay attention to these five factors to extend your roof’s lifespan and save money by avoiding unnecessary repairs or having to replace your roof prematurely.

Installation

When having your roof installed, make sure to choose a reputable company that is licensed and experienced in installing commercial roofs. An improperly installed roof can cause a large variety of problems including sagging and leaking.

Roofing System

The quality and types of materials used to build your roof will have a direct effect on how long it will last. While TPO or EPDM roof systems have a life expectancy of 22 to 35 years, an asphalt or metal roof can last up to 45.

Weather

While you certainly can’t control the weather, extreme weather conditions like rain, wind, and snow can take a toll on your roof. Even extremely sunny weather all year long can be problematic. Take the proper precautions to prepare for storms and inspect your roof whenever harsh weather hits.

Maintenance

All roofs are subject to wear and tear and will need to be properly maintained to last as long as possible. Perform routine inspections on your roof and quickly address any leaks you find. Replace damaged or missing shingles immediately and clean off any debris or algae growth.

Proper Ventilation

Excessive heat can cause damage your roof and quickly cut years off its life. Ensure that your roof and building is properly ventilated and insulated to help keep your roof cool. Not to mention, a well-insulated building will keep the interior nice and comfortable and help lower utility bills.

Inspecting your roof to make sure it is in the best condition is worth the time and money you will save down the road. Choose Andrews Roofing to install your roof and make any repairs you might need. Call us today at 757-296-0553!

How To Deal With Water Stains on Your Roof

When the outside becomes treacherous, a solid roof is your first line of defense against the elements. You can imagine how disheartening it is when the protective covering of your home starts to change in appearance—a clear indicator that your roof is feeling the impact of inclement weather over time. Water is among the most common causes of aging in a roof, leaving unsightly moisture stains that threaten to compromise the security of your house if left untreated. Consider the color of water stains and extent of damage when coming up with a solution for your roof.

Black or Green Roof Stains

Black or green water stains on your roof indicate growing organisms, such as algae or moss. The presence of constant moisture and sunlight makes for a delicious and cozy harvesting area for such microscopic tenants. They can lock in unwanted dampness or invite other, larger creatures to wreak havoc on the top of your house. Power-spraying or scrubbing the problem on your own is possible, but likely to cause further, irreparable damage.

White or Yellow Roof Stains

White or yellow discoloration on your roof suggests hard-water buildup from an air conditioner or evaporative cooler. This type of staining often occurs on lower areas roof beneath cooling units and sticks out like a sore thumb. Similar to algae-type staining, attempting to scrub or power-wash will probably make things worse. Rather, you can try fading the damage with a vinegar solution, which works to gradually dull mild stains without risk to the plants or animals around your home. Be careful of any harsher home remedies, as they can become dangerous if mishandled.

When in doubt, professional roofing companies are better equipped to eradicate roofing stains with special chemicals, sealers or new repellent shingles when necessary. Expert solutions work quicker and last longer, saving you the hazardous trip up the ladder. Call Andrew’s Roofing at 757-296-2897 or use our contact page for more information.
