Reasons To Replace Your Roof
The trouble with a wind damaged roof is that the exposed spots on the roof can be difficult to detect, especially if the shingles have been lifted. A shingle that has been lifted due to winds may have loosened the sealant and possibly the nail, all of which means replacing the roof.
Exposed nails can rust and lead to a leaky roof. Depending upon how many nails are exposed and how long they’ve been exposed it may call for a roof replacement.
Roofs will lose granules through the course of time, so whether you need a completely new roof depends on the age of your roof and how many granules remain.
Seeing curling shingles can mean a sign of bigger issues, like leaking, which can mean a roof replacement. Shingles can curl because they weren’t lined up properly, they’re old, they weren’t installed correctly, you have poor ventilation in the attic or you’ve got a layered roof. If you see curls, it’s best to have it get checked out sooner than later.
If you’ve got a leaking roof, there’s no time to waste to get it fixed. A leaky roof can lead to structural damage.
When a large hailstone hits an asphalt shingle, it can tear or even puncture the shingle. But usually, it just knocks granules off the surface. When a shingle loses its protective layer of granules, UV rays from the sun begin to destroy it. More granules fall off around the damaged spot and the bruise grows. The damage may not be obvious at first, so if you suspect hail damage, get an inspection from a roofing contractor. Most offer free hail damage inspections.
