Roofs are exposed to wear and the risks of damage throughout its lifetime. As a homeowner, you’re not expected to perform repairs, but knowing the difference between damage and normal roofing wear can be helpful when you need to make decisions. In today’s post, the roofing contractors at Allstar Construction share a quick guide to identifying the differences between the two.
Normal roofing wear is caused by exposure to changing weather conditions over the years. The key difference between normal wear and damage is that wear inevitably happens over a long time before it can impair a roof’s performance—mainly the reason why insurance doesn’t usually cover the repair costs caused by wear. The following are some of the signs of normal roofing wear:
Granule loss. Asphalt shingles are covered by a layer of granules that protect the backing material from damage caused by UV radiation. It also defines the color of the roof. Granules lose their adhesion and erode over time, resulting in worn-out or “balding” shingles. This is more evident on light-colored roofs, where the contrast with the asphalt-soaked backing material is more noticeable.
Curling or cupping shingles. Asphalt shingles lose their flatness as the backing material succumbs to years of thermal expansion and contraction, resulting in curling or cupping shingles. A roof will need to be replaced if it’s in this condition.
Roofing damage is caused by sudden events like impact caused by hailstones or by weather events like storms. Storm damage repair is generally covered by insurance providers. The following are some of the most common signs of a damaged roof.
Missing components. Roofing components such as ridge caps or flashing may get torn from the rooftop by high-speed winds. This is why it’s important to regularly inspect the roof — high winds can cause damage even on a clear day. You can avoid water infiltration and risks of further damage by having your roof fixed by your roofer as soon as you notice that components are missing.
Cracks or craters. Impact damage caused by airborne debris and falling tree branches can cause cracks on the rooftop and may cause shingles to fall off. Hail damage is a bit more difficult to identify, and the small craters caused by hail impact are often mistaken for asphalt shingle blisters, a type of manufacturing defect.
