Most warehouses, office buildings, and large freestanding commercial properties use some form of low slope roofing system. A low slope is anything under a 4/12 pitch or slopes 4 inches or less every foot. Low sloped roofs face many obstacles to keep nature out. Every building has separate factors that play into which roofing system would be most beneficial. We specialize in many options to best suit your needs.


EPDM is very durable single-ply synthetic rubber membrane comprised mostly of ethylene and propylene. It is available in a variety of widths and comes in 45 and 60 mils thickness. It is commonly applied to a stripped deck using a strong adhesive, but can also be mechanically fastened and anchored down in more difficult areas. EPDM has been a top choice for low-sloped roofs for over 40 years and is the most frequently used. This system is durable, holds up to scratches and scuffs, can easily be repaired, and is not easily damaged by UV rays leading to a potential 20-year life span.


Modified Bitumen

Modified Bitumen is an asphalt product and could be compared to a giant sheet-like shingle. Bitumen roofs have a long track record of being one of the longest lasting types of flat roofing systems if done correctly. It can be installed in hot or cold weather and is available in 1, 2, or 3-ply. The seams are typically torched together regardless of it being applied via self-adhesive sheets, hot mopped asphalt, or cold applied adhesives. A good bitumen roof will be coated in granules on the exposed side to protect it against UV rays and increase lifespan.

Polyvinyl Chloride

PVC (Polyvinyl Chloride) is a single-ply flexible thermoplastic membrane that has been used for decades. PVC gained popularity from its dependable heat-welded seams, high reflectivity, and superior resistance to water, chemicals, grease, fire, and punctures. The seams are hot air welded and form a bond stronger than the material itself making it extremely resistant to high winds and uplift.

Thermoplastic Polyolefin

TPO (Thermoplastic Polyolefin) is a single-ply reflective membrane that chemically bonds rubber, ethylene, and propylene.  It is as UV and heat-resistant as EPDM and is heat-welded like PVC. One of the main appeals to both commercial and residential low slope roofs is the energy efficiency it provides. The white reflective surface exceeds the EPA’s ENERGY STAR requirements and is also available in tan or grey.  TPO is durable and resists tears, impacts, punctures, mold growth, and dirt accumulation.
