Asphalt shingles make up about 80% of all residential roofing systems in North America. This roofing material owes its popularity to its great looks, dependability and low-maintenance nature.
How well do you know your asphalt shingles? Here are five facts about shingles that not every homeowner knows:
1. Asphalt and Fiberglass Shingles Are the Same
They are also called composition shingles in some areas. That’s because they are composed of a combination of different materials, including asphalt and the fiberglass fabric that reinforces the shingles and holds the tab together.
2. Asphalt Shingles Are Not All or Even Mostly Asphalt
Asphalt shingles are actually made from a combination of different materials. Regular asphalt shingles contain about 20% asphalt by weight.
3. Some Asphalt Shingles Contain Asbestos
These days, asphalt shingle manufacturers will never use asbestos. But in the old days, manufacturers used asbestos to provide their shingles with fire resistance. Many homes built before the 1960s still have asbestos in their asphalt shingles. This is one of the main reasons for roofing replacements performed by a licensed roofing contractor.
4. Asphalt Shingles Shed Granules During Installation
Those protective granules are used to cover the outer surface of shingles and give them extra protection against the sun. During installation, loose granules fall off the shingles. This is not something to worry about. There will be plenty of granules left on the shingles after installation. However, if you see plenty of granules in your gutters and around the roof, and your roof is old, it’s probably time to consider a roof replacement.
5. Nail Guns Are Just As Good As Hand-Nailing for Shingle Installation
As long as you hire a reputable contractor that uses modern methods and equipment, nail guns are just as effective and safe for installing shingles as using a hammer and nails.
