It is hard for any type of building material to withstand year-round weather extremes. However, asphalt shingles can take the abuse of cold and heat, snow, sunlight and ice for up as long as 15 years. The lifespan of a roof depends upon the type and weight of the shingle, the building location, the pitch of the roof, and how well the roof is maintained. The typical lifespan of an asphalt shingled roof is anywhere from 15 to 20 years. Metal roofing can last from 40 to 60 years. How long a roof will last also depends upon it being installed correctly. This is why it is important to use a professional roof installer when putting on a new roof. In Charlotte and Concord NC, Advanced Roofing and Exteriors has expert roof installers on staff to help you decide on the best roofing material for your new roof.
The basics of installing a new roof
When it comes to getting a new roof, some of the terms used by a roof installer can be confusing. Often, they will refer to asphalt-fiberglass or fiberglass shingles, but the most common term used is still asphalt when describing modern shingles. These types of shingles have a mat made from fiberglass which is embedded in an asphalt coating and then layered with mineral granules. If a home is getting a new roof, the new material is typically a lighter-weight version of asphalt shingles. These are called three-tab strip shingles. When considering a new roof, earlier is really better. It is important to factor in the weight of the roofing materials so the chance of overloading the roof is reduced. If your current roof is more than twenty years old, it is probably a good candidate for a new roof.
Evaluating an aging roof
One of the most obvious indicators of trouble on a roof is leaking or active dripping. As a roof wears, it may develop small leaks which will gradually worsen and may damage the internal structure of both the roof and the house. When a homeowner is checking a roof for problems, they should begin in the attic or upper levels of the home. A roof leak will almost always dry with a dark ring around its edges. These rings are from traces of asphalt which indicates that water is coming in through the roof. When checking a roof for damage or wear, a professional roof installer knows exactly how to check the roof, what to look for and how to prevent further damage. Advanced Roofing and Exteriors in Charlotte and Concord NC have professional roof installers who can thoroughly inspect a roof and provide the homeowner with an estimate for replacement.
