A Built-up Roofing is composed of alternating layers of reinforcing bitumen (asphalt) and fabric. It is finished with a top layer of aggregate such as gravel or stone. The layers provide strength while the top layer of aggregate ensures that the membrane does not deteriorate from the sun and other elements.

Modified Bitumen roof system is a two-ply application system. The installation contains a base sheet with no granule and a cap sheet granules protection. The rolled sheets can be installed by torching the sheets together, asphalt, or cold adhesives.

Single-Ply Membranes are rubber sheets and other synthetics that can be adhered chemically to ballasted or insulation creating a layer of protection to a commercial roofing facility. Single-Ply membrane roofing has 2 types: Thermoplastic Polyolefin (TPO) single-ply roofing membrane is made up of a single layer of synthetics and reinforcing scrim that is used to cover flat roofs. TPO is a revolutionary chemically and self-adhering membrane seamed with hot air. Ethylene Propylene Diene Monomer (EPDM) is a single-ply membrane consisting of a synthetic rubber compound that allows flexibility. EPDM is mechanically attached and seamed with seam tape.

Liquid-Applied Membrane (LAM) is a liquid-based, fully-bonding coating system for roofing and waterproofing applications. The coating cures to create a rubber-like elastomeric waterproof membrane. LAM can be applied over substrates such as bitumen, asphalt, and concrete.
