How's the Roof?
Posted May 24th, 2013 under renovations and repairs.
Spring is here, and it's time to clean the leaves from the eaves! While you're up there, have a look for broken, cracked, or missing shingles.
Two of the tell-tale sings that shingles are approaching the end of their lifespan is when the edges start to curl up or down, or the corners begin to round off.
A third sign is when granules start to disappear from the shingles. This allows the sun to break down the asphalt more quickly, which in turn loosens more granules. The granules are relatively heavy, so they often don't wash out of the eaves when it rains. If you find a quarter-inch layer of granules in your eaves, you will probably need to reshingle in a few years.
Sometimes, only a few shingles are affected, either because of manufacturing defects or because of varying temperatures at different points on the roof.
Some people recommend power venting (those noisy turbines you seen on some roofs), but it won't solve anything if there isn't enough air coming in at the bottom side through the soffit. Proper air circulation is also needed to avoid moisture build-up and mold formation on the plywood sheathing.
