Types of Commercial Roofing

There are basically two types of built-up roofing (also known as BUR). One is a coal tar pitch and the other is asphalt material that is used as the waterproofing element between plies of reinforcing felt.

Commercial Roofing

Modified Bitumen
Modified Bitumen is a membrane that is pre-manufacture in a factory and then applied to the roof. The product comes in rolls, and is modified asphalt or coal tar systems with rubber added for low temperature. This product typically uses a built-up membrane underlayment before final application. Modified bitumen membranes can be torch applied, self adhered or mopped in place with hot bitumen. This product has been used fairly often for replacement on existing commercial roofing.

Single-ply roofing systems are just that, a single ply of a roofing material made from several types of polymer plastics and rubbers. TPO and PVC are commonly used materials in the single-ply category.

Ethylene Propylene Diene Monomer is manufactured into large sheets for application to insulation on a roof. The material can be loose laid and weighted down with rock or pavers to hold the membrane in place. It can also be fully or partially adhered as well. Seams and the membrane are adhered with contact adhesives, with seams sometimes joined with a sealant. Toppings may or may not be required by the manufacturer in many cases.

Commercial Roofing

AES Epoxy
AES Epoxy Roof Coating is a fire rated, flexible two-part epoxy with a 20 year warranty designed to protect a variety of surfaces including rubber, concrete, foam, plywood, metal and petroleum-based surfaces. AES Epoxy is especially suited to applications where surface movement may defeat the protection of a rigid coating. It is excellent for waterproofing EPDM, TPO, PVC, built-up, single ply, polyurethane foam, concrete, and metal roofs. The flexibility retained by Advanced Epoxy Systems allows for surface movement caused by thermal shock to most structures.
