There are several types of roofing membranes that can be used on low slope roofs:
This type of single ply membrane is based on plastic polymers and have seams that are either heat welded or chemical welded. This allows for seams that are as strong or stronger than the membrane itself.
These membranes are made from polymeric materials that are chemically cross linked or vulcanized, or cured, and can only be bonded to similar materials by adhesives.
Low Slope Metal Panel Roof Systems
Metal panel roof systems:
Metal roofs are a very durable roofing system that can be installed over a continuous deck that provides support or can span between supports.
Built Up Roof (BUR) Membrane Systems
Built Up Roof:
Also known as tar and gravel roofs, this system consist of alternating layers of bitumen and membrane, that can be installed by hot tar or asphalt or by cold process adhesive. The surface is typically topped with aggregate, cap sheet, mopped asphalt, or coating.
