Why it’s explosive: ”Most people don’t pay any attention to their roof until they see water coming through the ceiling!” says Bill Jacques, outgoing president of the American Society of Home Inspectors and owner of American Inspection Service in Charleston, S.C. But if you see drips in your living room, the problem is already far gone. A new roof could cost you “probably $8,000 to $10,000,” Jacques says.
Snuff the fuse: “Some people say, ‘I’ve got a 20-year shingle, it’s gonna last 20 years.’ Well, no it’s not,” Jacques says. “I would just recommend that about every five years they have the roof inspected.” One of the telltale signs of a wearing roof is coarse sand pooling at the base of gutter downspouts; the sand is most likely the granules of the shingles washing off. If you see a lot of it, then it’s a good idea to have someone climb higher. If you can safely get on the roof (be careful!) and the surface feels slippery, that’s another sign that the shingle material is coming off, Jacques says.
You can find evidence of additional problems under the roof. Water will usually enter the attic first. Hire an inspector, or look for stains around the chimney and the stack vents, or around other venting pipes that exit the house. Those are places where the metal flashing can fail, says Jacques. Also, look around the attic for wet and, or damaged insulation. Discovering issues early on could mean the difference between repair and replacement — or a few hundred dollars rather than thousands.
