Although asphalt shingles are one of the most popular roofing materials in the United States, there are still plenty of misconceptions about them. To separate fact from fiction, Kroll Construction debunks the following common myths about asphalt shingle roofs.
Myth #1: Asphalt shingles are different from fiberglass shingles. Asphalt shingles and fiberglass shingles are the same. They may be called “asphalt shingles” because they contain asphalt for the weatherproofing and water-resistant material. They may also be referred to as “fiberglass shingles” as fiberglass is the reinforcement fabric that holds the shingle together. As such, both terms are correct and can be used interchangeably. In some areas, asphalt shingles are also known as “composition shingles” because they are composed of a combination of a few raw materials.
Myth #2: Asphalt shingles are made with asbestos. This was true many years ago, but these days, asphalt shingles no longer contain asbestos. In North America, fire safety codes require exterior building materials, including roofing materials, to have a certain level of fire-resistance. During the mid-20th century, some shingle manufacturers promoted fire-resistant roofing materials that were made using asbestos fibers. However, by the 1960s, shingles containing asbestos were phased out. Nowadays, asphalt shingles are made fire-resistant with the addition of safer mineral stabilizers.
Myth #3: Asphalt shingles are sealed immediately. Keep in mind that shingle sealants are not peel-and-stick materials. In fact, for the sealant to be activated, shingles need to receive sufficient solar warmth. The length of time for the seal to cure may depend on many factors, including your home’s location and climate conditions. For this reason, there is no exact time for when the seal cures. All you have to do is wait, and the shingles will eventually seal. When activated by the sun’s warmth, the shingles create a strong bond to ensure maximum protection against blow-off and moisture damage.
Myth #4: Installing asphalt shingles with a nail gun is bad. Staples were initially used instead of nails for pneumatic shingle attachment. Unfortunately, these were deemed as more prone to crooked installation, resulting in a roofing system with poor wind resistance. The truth is, however, that it doesn’t really matter whether you use a nail gun or nail your shingles by hand. As long as your roofers make sure that the nails are in the correct location and not overdriven, either method offers a suitably finished roof.
