Three Common Ann Arbor Roof Issues
One of the most common issues Ann Arbor roofing contractors find on during a roof inspection is missing or damaged shingles. Wind damage being the most common cause of missing or bent over and cracked shingles. Here in Ann Arbor there are quite a few farm fields and the wind has little to block it. When roofing contractors see shingles that have a crack running horizontally across it just under where is meets the shingle above roofing contractors know it is wand damage. Unless of course someone is climbing up and folding up a few shingles just for fun, doubtful.
The other issue Ann Arbor roofing contractors see often is that the rubber boot flashing are damaged. The rubber boot flashing is the specially designed metal and rubber piece that is designed to fit around the plumbing vents that penetrate through the roof. Many times the rubber that creates the water proof seal around the plumbing pipe is cracked or damaged. These cracks and tears can be large allowing lots of rain to enter the interior portion of the home. They can also be large enough to let birds in to the attic to nest.
Lack of a gap between the shingles and siding is another issue that Ann Arbor roofing contractors find frequently. With the roof designs in which a roof butts up against an exterior wall there should be a gap between the siding and the shingles. The lack of an inch or so makes it difficult to install an additional layer of shingles. This is because there is not enough space remaining between the siding and shingles to allow the thickness of additional shingles. If the siding is wood then it is a larger issue because the wooden siding will have an easier time wicking of water form the shingles that are in contact. This increases the chance for rot and deterioration.
