Common Roof Leak Causes in Bellevue
With normal aging and the severity of the elements, every roof may eventually experience a roof leak. While roof cleaning, inspections and maintenance will reduce this risk and postpone damage, a leak may still occur eventually. Roof leaks are not uncommon, and knowing what to look for can alert you to a problem and promptly phone for professional assistance.
Besides damaged or missing roofing material, here are three common Pacific Northwest roof leaks causes:
1. Faulty and Brittle flashing
The thin metal bands or flaps that cover or protect the caps, corners, valleys, fascia and other parts of the top of your home are known as flashing. This part may become weak or corroded over time. Caulking also becomes dry and brittle with the passing of years, and both can lead to leaks in valleys and around roof penetrations such as vents, chimneys and skylights. Custom metalwork can provide quality replacement flashing that seals even the smallest openings.
If your home is near a tree or two, falling branches can weaken or damage roofing material. The build-up of leaves and moss allows water to sit where it shouldn’t. Both can cause your roof to leak, which is why regular debris removal is a must-do.
3. Clogged gutters
Gutters clogged with debris cause rainwater to pond or flow where it shouldn’t, often resulting in water ‘wicking’ under roofing materials or running inside soffits or walls. Prevent this by clearing the gutters at least twice a year.
