Three Types Of Roof Damage That Are Harder To Spot After A Storm

After a thunderstorm, hail storm, or hurricane blows through your area, it's wise to look over your roof for signs of damage. But while most homeowners know to look for missing or peeling shingles, this is not the only type of damage a roof can sustain in a storm. Here are three other types of roof damage that are often overlooked until they cause leaks or water damage. 

Loose flashing

Flashing is the metal covering that adheres to your chimney, vent pipes, and the like. High winds and wind-driven rain can cause the top of the flashing to peel away from the structure it surrounds. Then, when the wind blows the right way, rain ends up trickling down behind the flashing, causing damage to the wooden underlayment of your roof. 

Look closely at the flashing, and if you see any gaps, pockets, or places where it appears to be peeling away from the roof, make an appointment to have it repaired through a roofing company like Emerald Roofing. (Replacing flashing is not a good DIY project since it requires metal cutters and the removal of many shingles.)

Lifted shingles

Sometimes shingles lift up along the edge without getting blown off completely. These may not cause leaks initially, but they will leak if water trickles down them at the right angle. Or, they may later blow off in a gentle breeze and go undetected because you never would have suspected that wind to do roof damage.

To spot lifted shingles, stand with your eyes level to the roof and look straight across it. If you see any shingles poking up further than the rest, then you need to take care of them. You can do this yourself by pounding a few roofing nails through the lifted shingle edge and then covering the nail heads in roofing cement -- or you can just call your roofing company.

Buckling underlayment

When looking straight across the roof for lifted shingles, also keep your eye out for any sections that appear to be sagging. A tree branch landing on the roof can cause the wooden underlayment, which forms the base of the roof, to crack. Note that the tree branch may not still be present -- it could have blown off.

If you do see an area where the roof is sagging, have it repaired sooner rather than later. Decay can quickly set in to a damaged underlayment, increasing your risk of a collapsed roof.
