Long-Term Damage of a Leaky Roof

Signs of Leaking

• Aside from the visual detection of water caused by a leaky roof, more signs that a roof has leaks may be noticeable. Yellow or brown stains appearing on the ceiling, or along the tops of walls may indicate a slow leak. Wet weather — especially times of heavy rains, snow or ice — may be accompanied by a noise that sounds much like a dripping faucet.

Checking for Leaks

• The best way to prevent long-term damage from roof leaks is to stop them from becoming long-term leaks. Check the roof of your home regularly, especially during long periods of inclement weather, accessing it from the attic or crawlspace above the rafters if one is available. Look for holes in the roof or any areas where more wind seems to be passing through the roofing materials. If you cannot access the roof from the inside, check it from above. From the roof, look for loose or broken shingles and for loose flashing around chimneys and other fixtures.

Mold and Mildew

• The issues that develop from a leaky roof depend upon how long the leak exists. Among the first major issues is the growth of mold and mildew on the ceiling or walls of your home. Beyond being unattractive, they can cause a number of health issues, including respiratory problems, and can be difficult to remove.

Structural Damage

• Long-term damage to a leaky roof can be extensive and even irreparable. As water leaks into your home, it may be absorbed by insulation, joists, wall studs and drywall. Exposure to moisture causes most of these elements to weaken or fail. You may notice “sagging” of the ceiling or the walls, peeling paint and other signs of water-damage. The breakdown of structural materials can lead to deterioration of the home’s structure and eventual collapse.
