Roof debris such as leaves, pine needles, and twigs retain a good amount of moisture. This sustained moisture eventually leads to shingle deterioration. Just like a compost pile in your garden, this break down process effects your roof surface just the same. If your home is positioned under a canopy of pines or oaks like many Tallahassee homes, you need to clean the roof often to avoid premature failure.
Many older homes used oil burning furnaces for heating (1950′s+ era). These smaller (roughly 18″ x 18″) chimneys where used for exhausting the fumes. Most often, they are no longer being used for the intended purpose. During a roof replacement, one should consider omitting them completely. Fewer roof penetrations means fewer flashing details. Fewer flashing’s results in less potential items to cause roof leaks.
Signs of leaks at an overhang (such as wood decay or staining) could mean there is a problem with the starter course or drip edge metal. If you suspect an issue, you should contact a licensed roofer to avoid further costly damage.
