Below are some additional details on some of the commercial roofing applications we commonly use in our service areas.

R-PANEL

R-Panel is easy to install and can be used in a variety of applications including roofing and siding material for commercial, agricultural, residential, self storage, and equipment screens project.
Exterior applications include: Total roofing area, an accent to a roof in conjunction with other architectural elements of design, metal siding, decorative fencing, restaurants, and movie sets. Interior applications include: Focal point or backdrops such as a backsplash in a bath or kitchen, textured ceiling, and wall treatments.

TPO

Thermoplastic polyolefin (TPO) single-ply roofing membranes are among the fastest growing commercial roofing products and have gained broad industry acceptance for their many performance and installation advantages. As demand increases for heat-reflective and energy efficient roofing systems, TPO single-ply roofing membranes continue to provide exceptional resistance to ultraviolet, ozone and chemical exposure.

Modified Bitumen

Similar to tar and gravel roofing, the modified bitumen (torch down) roof consists of layers of fiberglass and polyester with bitument that are added to the regular tar and gravel layering system. These extra sheets are torched down in the overlap areas during the installation process, using large flame throwing torches that melt the asphalt at the seams to join them together, which is the origin of the name torch down roofing. The final result is the vulcanization of a large rubber sheet onto a fiberglass base.
Also called torch down, due to the mixing of asphalt with rubber compounds, torch down roofing provides additional strength and resistance to a flat or low sloped roof. It is not, however, suited to areas prone to high rainfall or snowfall, and has an average life expectancy of about 15 years. A torch down roof is also significantly more attractive than a standard tar and gravel roof.

EPDM

EPDM is an extremely durable synthetic rubber roofing membrane (ethylene propylene diene terpolymer) widely used in low-slope buildings in the United States and worldwide. Its two primary ingredients, ethylene and propylene, are derived from oil and natural gas. EPDM is available in both black and white, and is sold a broad variety of widths, ranging from 7.5 feet to fifty feet, and in two thicknesses, 45 and 60 mils. EPDM can be installed either fully adhered, mechanically attached or ballasted, with the seams of the roofing system sealed with liquid adhesives or specially formulated tape.

Mop Down Roofing

Asphalt built up is the most common form of roofing used for low sloped roofs (2:12) in America, constituting a large percentage of the overall number of roofs in the United States. Asphalt built up refers to several layers of reinforcing felt between asphalt and plies, or coal tar bitumen, which are covered with a surfacing material that serves as a ballast and holds them down, also reflecting UV rays.
Usually the surfacing material used is gravel, and for this reason it is sometimes also called tar and gravel roofing. There are, however, other kinds of built up roofs, including smooth Asphalt built up, and Ballasted Asphalt built up. Depending on weather conditions, the average life span of asphalt built up roofs is approximately 10-20 years.
