Low Slope Roofing is defined as a roof having a slope of 3-in-12 or less. Low slope roofing includes water impermeable or weatherproof types of roofing membranes installed on slopes of less than or equal to 3/12 pitch.
There are two types of materials commonly used on low-slope roofs:
Ethylene Propylene Diene Monomer (EPDM)
EPDM is a synthetic rubber most commonly used in a single ply roofing system because it is readily available and simple to apply. Seaming and detailing has evolved over the years and is fast, simple, and reliable with many membranes including factory applied tape, resulting in faster installation.
Thermoplastic Polyolefin (TPO)
This single ply roofing material can be fully adhered, mechanically fastened, or ballasted. TPO does not degrade under UV radiation. It is available in white, grey, and black.
