EPDM Roofing Systems

EPDM roofing systems are probably the most common roofing system in the commercial roofing industry. EPDM is a quality, yet affordable, rubber roofing material that is durable and easy to both repair and installs. EPDM stands for ethylene propylene diene monomer. These roofing systems are great for commercial properties that need a new roof quickly on a budget. EPDM roofing systems are easily installed on top of existing commercial roofs, making it a favorite choice of replacement roofing contractors.

Single-Ply TPO Roofing Systems

Single-Ply TPO is a thermoplastic roofing system known for its durability and quick, easy, affordable installation. TPO is made out of ethylene-propylene rubber which is extremely durable. These roofs are completely resistant to any rips or tears, which means your entire building could flex without fear of roofing impact puncturing. When installed properly single-ply TPO commercial roofs should last around 20 years. TPO’s unique rubber chemistry makes it extremely environmentally friendly, being resistant to both toxic gases and growing organisms like mold and algae.

Single-Ply PVC Roofing Systems

A single-ply PVC roofing system is a slightly higher grade of thermoplastic engineering than a TPO system. The PVC rubber membrane is resistant to almost all chemicals and stronger in the seams than other thermoplastic roofing systems. Of course, a single-ply PVC roofing system is slightly more expensive, but it is also a greater long term investment for your commercial property. Roofing industry professionals agree that single-ply PVC roofing is considered the best thermoplastic roofing system for commercial business properties.

Built-up Roofing Systems

In the commercial roofing industry, built-up roofing systems are consistently recommended as the most cost-effective, sustainable roofing option for low-pitch commercial roofs. Built-up roofing systems use layers to reinforce the structure of the roof, producing a quality commercial roof for generations to come. Often called “asphalt and gravel” or “tar and gravel” roofs, built-up roofing systems alternate using layers of tar, gravel, asphalt, or other insulating materials to limit roof movement, roofing wear and tear, and water damage. Commercial properties that install a built-up roof can expect longevity from their investment with low-risk of any damage occurring.

Slate and Tile Roofing

Slate and tile roofing are both great options for commercial business properties because of their beautiful unique aesthetic, and long-term durability. Slate and Tile roofing dates back to ancient China, where you can still visit ancient structures with slate and tile roofing still intact. A slate and tile commercial roof installed properly should outlast the building it is built upon. Even low-quality manufacturers often offer lifetime warranties on slate and tile roofing, most commercial slate and tile roofs last at least 50 years. The sustainability, low maintenance, and design variability make slate and tile roofing a great option for any commercial property.

Metal Roofing

Metal roofing is exploding across the nation in the commercial roofing market. While there are other types of commercial roofing that are temporarily cheaper, metal roofs have long-term sustainability that is significantly better, making metal roofing for your business a much better purchase for the future. Where cheaper roofing materials such as asphalt need to be repaired or re-installed every 10-15 years, metal roofing lasts twice as long. Metal roofing also offers a unique aesthetic variability as far as design options. Depending on the manufacturer, metal roofing systems have been known to copy almost any roofing shingle style from tile and slate to asphalt and shake. Metal roofing variations in make, style, color, and finish are so extensive that metal roofing can match any other style of roofing.
