Of all the problems you can encounter around the house, roofing problems are by far the sneakiest.
Leaks can develop unnoticed for years causing rot, mold, warping and other expensive damage.
Experts recommend that you go into your attic or crawlspace at least once a year after a rainstorm to check for leaks and water damage.
Special attention should be paid to areas where you have flashing (the metal or plastic weather stripping that will be around chimneys, pipes, vents, roof planes and eves) because this is typically the most likely area to develop leaks.
It is also recommended that you visit the surface of your roof yearly during good weather to look for any loose, missing, eroded, warped or otherwise damaged shingles and to check the overall condition of your roof.
