Asphalt shingle is by far the most widely used roofing system on steep-slope roofing applications. And for good reason, too: Architectural shingle roofing systems now carry a limited lifetime warranty.
Although this type of shingle is referred to by different names, most roofing shingles used today are technically known as asphalt fiberglass shingles. The fiberglass mat embedded in the shingle provides an extra measure of strength, protection, and tear resistance.
These shingles are the most popular type of roofing for sloped roofs because they're affordable, easy to install, durable, and available in a wide variety of colors. Premium grades of "laminated" asphalt fiberglass shingles are typically warrantied for 50 years.
The Mechanically Fastened/Attached System uses fastening plates to secure the membrane. This system provides faster installation times without the use of adhesives and seam tapes. Membrane seams are then heat-welded with specialty hot-air equipment. Mechanically attached is the most prevalent method of installing TPO membranes.
Mechanically attached systems carry warranties of up to 25 years.
The Fully Adhered System uses TPO bonding adhesive to adhere and secure the TPO membrane to the insulation board or recovery board. This method does not require the use of fastening plates to secure the membrane. Membrane seams are then heat-welded with specialty hot-air equipment.
Fully adhered systems carry warranties of up to 30 years.
A ballast roof system is a loose-laid roofing system that is not anchored or adhered to the decking, except for the perimeter and around penetrations/curbs, and is ballasted throughout, generally with gravel. Ballasted is the least prevalent method of installing TPO membranes and is used less and less today.
Asphalt shingles are available in three profiles: 3-Tab (basic and least costly), Laminated (Architectural or Dimensional), and Premium. In addition to the style/design options, there are up to 20-25 different colors to choose from. With such a wide range of available options, you are sure to find a perfect match.
By far the greatest advantage of composition shingles roofing is its relatively low upfront cost. This is the most affordable roofing option in the short term, which is why so many homeowners favor it. In most cases, a properly installed asphalt shingles roof will provide your home with a decent level of protection with an average lifespan of 12 to 17 years, all for a modest upfront cost.
A shingle roof system installation takes much less time and expertise than installation of other materials, such as metal and tile roofs, making them more cost efficient as well. A relatively easy installation process results in reduced labor costs and therefore a less expensive overall roofing system.
