When it comes to replacing your roof, it’s typically not a want, but a need. In that time of need, it’s important to be as informed as possible so that instead of making a quick decision, you make the right decision. We gathered our most frequently asked roofing questions to help guide you in that process.

What is in a shingle?
Shingles are made of multiple layers: asphalt, fiberglass, asphalt, and cinders. These layers come together to deflect the sun’s heat, protect the roof from water, and give the roof its color.

What’s the difference between an architectural shingle and 3-tab shingle?
An architectural shingle is a newer shingle design that looks elevated and quilted, mimicking the look of cedar wood. A 3-tab shingle is more flat and plain. With the advent of the architectural shingle, the 3-tab shingle has become outdated.

What are those black streaks on my roof?
Those black streaks are actually algae. Algae need water to grow, which means the shingles must be absorbing moisture. This can happen because the shingle has delaminated due to expansion and contraction, allowing water to seep in, or because of a lack of sun on the shingle, preventing the shingle from drying properly. Once algae are present, its roots can grow through the shingle, causing further delamination and allowing water to travel through the shingle and onto the roof decking. Over time, this will cause considerable damage to your roof and the decking which serves as its foundation.

Why can’t I just patch the section of the roof that’s leaking?
Water follows the path of least resistance, making it very difficult to identify the source of a leak. When you have a leak in the kitchen, that doesn’t necessarily mean the water is coming in from the roof above the kitchen – it could be coming from a section above the family room and traveling all the way to the kitchen. Therefore, fixing leaks tends to be a bit more complex than just patching the roof.

Can you put another layer of shingles on top of my existing shingles?
By code, you’re never allowed to have more than two layers of shingles on your roof because the plywood underneath cannot support that much weight. Furthermore, if you’re having issues with your roof, putting another layer of shingles on top only masks the real problem. Think about it like this: When you have a cut, the best thing to do is to remove the dirty Band-Aid, clean the wound, and put a new Band-Aid on top. You would never put a clean Band-Aid on top of the dirty Band-Aid.

Typically, why do roofs fail?
One of the main reasons roofs fail is due to extreme heat in the attic, especially in the summer. While most attics have an exhaust, many do not have proper intake, creating a vacuum effect that traps the hot air. The heat causes the shingles to bake like bacon, and shrink. When the shingles shrink, it creates avenues for water to creep underneath, causing shingles to fly off or moisture to seep into the attic

To eliminate this issue, we install both a ridge vent and a Power Vent. The Power Vent lets outside air in, which then pushes the hot air out the ridge vent. This circulation allows the temperature of the attic to more accurately reflect the outside temperature, eliminating any heat issues.

How long do roofs last?
This is a very tough question to answer. Most shingles have a 20-30 year rating, meaning that in perfect conditions (installed perfectly, proper ventilation, no extreme weather), you should get 30 years out of them. The problem is, those variables are rarely ever perfect and in most cases, those issues are not covered by your warranty

That’s why Power offers a 50-year warranty on the entire roof system, not just the shingles, and a lifetime labor warranty. This gives you complete peace of mind, knowing you will never spend another dollar on your roof.
