Composition Shingle
Composition asphalt shingles are the most commonly used roofing system for steep-sloped roofs (roofs that are not flat); because of ease of installation, there is a myriad of color and style options is by far the most cost-effective choice. The traditional three-tab asphalt shingle, which has a flat two-dimensional appearance, is the most commonly used, and you will see it on most commercial buildings. Architectural shingles have a three-dimensional look and can come in styles that resemble wood shakes, tile, or other types of roofs.
Other Roofing Systems
PVC (Polyvinyl Chloride)
PVC roofing systems have been in use for about 40 years, and they currently account for about 10% of the roof coverings in America. They are extremely durable, highly resistant to punctures, dirt, and debris.
Tapered Insulation Systems
Tapered insulation systems are designed to provide the slope that is lacking on flat roofs so that proper drainage can then occur as desired, thereby extending the life of the roofing system as a whole.
EPDM (Ethylene Propylene Diene Monomer)
EPDM roofing systems have been in use for about 50 years and, throughout that time, they have been successfully employed as a waterproof roof covering.
