Downpour detective solves ceiling leak

Q: I read your column about the e-mail from Nancy V. and her inability to locate the source of a leak that caused damage to her dining-room ceiling but not to the bedroom ceiling above. I had the same problem several years ago and experienced similar frustrations. Nobody seemed able to find the source.

Finally I insisted that my husband remove what I thought was a damaged siding shingle. He found that the installer had bent down one corner of the eaves box when installing it. During heavy rains, the water overflowed and ran down between the walls, then across the dining-room ceiling to the center light fixture.

Having a new eaves box installed correctly fixed my problem. Perhaps this information will help Nancy V. and others. — Mary D.

A: Thank you, Mary! I mentioned in a previous column that a house, besides providing shelter, is a system that can keep it occupants comfortable and healthy. If something in the system is damaged or incorrectly installed, that comfort is compromised.

The eaves box end is part of the fascia (the horizontal covering along the roof eaves that protects roof timbers) and is found at the corners of the eaves. Damage to this or any part of the roofline system can certainly cause interior leaks.

A visual inspection of the roof, its joints, flashing, eaves, soffits, gutters and other protective systems is a very important suggestion. Note any areas that are damaged or “not quite right” — dirtier than the surrounding area, corroded or rusty, or clogged with debris — and contact a roofing professional for further examination.

Also, remember to get a written estimate and a detailed explanation of damage and suggested repairs from the roofer before agreeing to have the work done.

HOME TIP: Spring is the most important time to inspect the exterior of a house for damage, warping or cracks caused by weather and debris strikes.
