Sylvania Roofing: Article About Types Of Asphalt Shingles
Asphalt shingles are one of the easiest to install and most affordable roofing options available for homeowners. They are easy to repair and last between 20 and 30 years when they are properly maintained. When asphalt shingles reach the end of their useful lives, Sylvania roofing contractors can opt to take them to a recycling plant where they are turned into other asphalt products.
There are two basic types of asphalt shingles: fiberglass and organic. These designations refer to the material used to construct the base of the shingle. Organic shingles have a base that is constructed out of felt paper and soaked in asphalt to make it waterproof. The waterproofed felt is then coated with another waterproofing layer of asphalt before a sticky asphalt layer is added. Ceramic granules are then embedded in the layer of sticky asphalt to improve the shingle's UV resistance. Organic shingles are considered more durable and flexible than fiberglass shingles, but they can absorb water and warp after a period of years.
Fiberglass shingles have a bottom layer that is constructed out of fiberglass, which is more waterproof than felt paper.

This means that the fiberglass mat does not need to be soaked in asphalt prior to adding the additional layers. Homeowners that choose fiberglass shingles can expect a thinner and lighter shingle. Fiberglass shingles also have higher fire ratings than organic shingles and typically come with better warranties.
Fiberglass and organic shingles come in two styles, including three tab and architectural. Three tab shingles are the more common of the two. They get their name from the tabs located at the bottom of the shingle. These tabs give the appearance of separate shingles once they are installed. Three tab shingles have decent useful lives, and they can be installed on virtually every slope of roof.
Architectural or laminated shingles are thicker and more durable than three tab shingles, which gives them better resistance to wind, rain, snow and hail. They also have longer useful lives than three tab shingles. While three tab shingles are comprised of a base mat, asphalt waterproofing layer, sticky asphalt layer and a top layer of granules, laminated shingles are comprised of two shingles fused together. These layers give the shingles a dimensional design.
Homeowners can purchase architectural shingles that look like slate or tile but that do not have the drawbacks or maintenance requirements of those materials. Downsides to architectural shingles include weight and expense to install.
