Layer Cake Shingles

How Many Layers angry bird of Shingles Are Legal on a Home?Asphalt shingles are perhaps the most common type of roofing material in the Southwest and especially in Tucson. They are durable, light weight and less expensive than many other options. They also come in every color imaginable, as well as offering new options like dimensional shingles to give a more architectural or 3D look to your roof.In the early 1900s, the U.S. recognized the need for standardized building codes, particularly along the East Coast. Every region of the U.S. adopted some form of code eventually. Of course, we independent souls that settled the West and Southwest tended to be a little slower in adopting these sorts of restrictions. Until recently, there were no rules governing how many sets of shingles could be layered on a roof. Many older homes have lots of layers when one layer wore out, a new layer was installed over top of the old one. Tucson roofing contractors have discovered as many as six or eight layers on some homes. Of course, adding more layers provides additional protection from the elements for your roof, but there are hidden dangers and obstacles. Homes are structurally designed to handle only a specific amount of weight. Adding more weight than the structure is designed to handle is asking for trouble. Extra layers could be covering up dry rot on your roof deck. The roof may appear sound from the top, but underneath, mold, mildew and rot could be eating away at the roof deck, joist and supports, making your roof unsound. Another concern is that the tiles will conform to the shape below. For the most part, shingles tend to lay fairly flat (except for the new Syma s107 upgrade dimensional shingles), but keep in mind that the new shingle layer will take on the shape of the old, so if the old shingles are very curled, twisted, or buckled, the new roof will eventually look the same AND the life span of the new shingles may be air swimmers decreased. This may also void the manufacturer's shingle warranty. Whether you are Air Swimmers considering having your home re-roofed, or whether you simply want to upgrade your existing roof, you should consider exactly how many layers of shingles you can and should have on your roof. While multiple roof layers can offer additional protection, every property is unique, and needs to be addressed on an individual basis.
