In the event of a leak, take immediate action, as a leaky roof can cause significant damage to insulation, walls, ceilings, flooring and personal property. Larger leaks will undoubtedly cause greater damage, but even a tiny leak can cause enough damage to require replacing the entire ceiling.

Often, the asphalt compound or caulking material used with flashing - or the rubber used for sealing pipes and other protrusions - dries out from exposure to the elements and the sun's UV rays. The dried out materials crack or loosen the seal, allowing water to penetrate.

The good news is that these types of problems can usually be fixed quite cheaply with asphalt cement - a repair that will last around three years. Alternatively, you can replace the flashing, which should last more than ten years. Rusted and corroded flashing can also be the source of leaks. They can be cleaned up and painted with a rust-resistant paint to squeeze more years of service, but severely deteriorated flashing and vents should be replaced.

Debris that has been sitting on the roof for awhile may have caused some rotting of the wood frame and sheathing, and may require a roof inspection. Also, gutters filled with leaves and debris, and clogged downspouts, allow water to back up, which can cause leaks in the roof. Gutters should be cleaned out periodically, and downspouts checked for clogging.

A buildup of ice at the eave, often called an ice dam, can also lead to roof leakage. It can even cause structural damage to the roof's framing system. One of the best ways to prevent an ice dam is by using an eave-heating system - heated wires that are strung on the roof above the overhang which prevent the water from freezing, and promoting proper watershed. A worthwhile investment if your roof is prone to ice dams.
