One of two types of asphalt shingles available, fiberglass asphalt shingles are the most popular, rather inexpensive and simple to install. Historically, fiberglass asphalt shingles have come to replace the asbestos roofing shingles. But they have since become widely popular, mostly in cold climate regions such as Canada and the northern United States, but in warmer regions, even those prone to extreme climate conditions such as Florida, as well.
When homeowners compare fiberglass asphalt shingle specifications with those of the organic type, they will find it lighter in weight. Organic asphalt shingles weigh about 40% more than the 1.8 to 2.3 pounds per square foot, the range of prices of fiberglass asphalt shingles, largely since the fiberglass mat is not saturated with asphalt. Weighing less, they are also lighter to carry up the ladder, thus more comfortable for homeowners who want to install them on their own. The use of glass fiber grants fiberglass asphalt shingles the highest fire rating available, protecting your roof from the spread of a flame, to go along with other advantages, such as heat and humidity resistance.
The use of different fiberglass shingles materials influences the variance homeowners will find in the market. This affects the quality and performance of fiberglass asphalt shingles, as well as the different attributes they own. It is advisable to compare fiberglass asphalt shingle material according to the industry standards, set by the American Society for Testing and Materials.
