Five Common Locations For Roof Leaks

A leaking roof doesn't always mean you have a failed shingle or a puncture. The following are five common location of leaks that are sometimes overlooked.

1. Chimneys and Vent Flashing

One of the most leak-prone areas of any roof is around the chimney and various vent stacks on your roof. The joint where these items emerge from your roof are typically sealed with flashing — metal sheets that are caulked into place with a sealant or roofing tar. Over time, the flashing can corrode or the seals may crumble, resulting in a leak. The good news is you can have the flashing replaced without the need for a full roof replacement.

2. Along the Eaves

Eave damage is most often the result of improperly maintained gutters. Clogged gutters result in water backing up onto the eaves of the roof, which can cause shingle and fascia board decay, as well as lead to water beneath the shingles. Ice dam formation is another reason for leaks along the eaves. Keeping your gutters maintained and watching for ice dams prevent eave leaks.

3. Inside the Valleys

The valleys or dips along your roof become a route for water runoff. Since most of the water draining from your roof must travel along these valleys, it is imperative that the shingling is in good condition and that the area is well sealed. If there are issues here, then you will end up with water leaking into your attic. Periodically have the roof valleys checked to make sure they are still watertight so that you can avoid troublesome roof leaks.

4. Skylight Perimeters

Skylights are notorious for leading to roof leaks. Leaks can occur around the perimeter of the skylight, particularly along the top edge, if the window isn't properly sealed. Putting in water diverters above the skylight can help reduce this type of leak. If you have a skylight that can be opened, then there are also leak concerns around the movable part of the window.

5. On the Shaded Face

The side of your roof that spends the most time in the shade is also likely the dampest part of the roof. For this reason, it's not uncommon for moss to take hold. Moss itself isn't damaging, but it can lift shingles so that water can seep beneath. If there is increased moss and algae growth on part of your roof, have it cleaned off so you can avoid leaks.

Contact a roofing contractor in your area if you suspect that your roof is leaking.
