Asphalt Shingles are one of the most common choices for roofing materials. As a matter of fact, at least 75% of the homes in the United States use asphalt shingles. Asphalt shingles come in various styles and costs and have warranty packages from 20-40 years.
By far the most popular roofing material is asphalt shingles due to their relatively low cost and durability
There are two types of asphalt shingle construction: Fiberglass mat based shingles and Organic mat based shingles.
Fiberglass based shingles are thinner and lighter, as their backing is made out of a fiberglass mat. Note: A bundle of asphalt shingles can weigh between 70 and 140 lbs and there are typically 3 bundles of shingles per square (100 sqft per square of shingles). Consequently fiberglass mat based shingles are easier to lift making a roofer’s job easier when carrying shingles up a ladder. Fiberglass mat shingles are also more fire retardant and typically have slightly longer warranties than organic based shingles.
Organic based shingles are heavier and considered more rugged as their mat backing is made out of felt paper and asphalt. They are heavier due to the fact that there is literally more asphalt used in them than a Fiberglass mat shingle. Organic mat based shingles are also considered more flexible than fiberglass shingles, however they are known to be more water absorbent and can warp over time. As a result of these differences Fiberglass mat shingles are used much more prevalently in the southern and central part of the United States, and Organic mat based shingles are used more in the northern part.
Fiberglass Asphalt based shingles used on your home should be compliant with ASTM D-3462 standards, and Organic based shingles used on your home should be compliant with ASTM D-225. More and more municipalities are requiring shingles to meet these standards, so you should check with your local building inspector and read the label on the shingles prior to purchasing them. Fiberglass and Organic mat based shingles are comparably priced.
