Flat Roofing

Behmer Knows Flat Roofing

Flat roofing, specifically hot asphalt built up roofing (BUR), is where we got our start and we still do it almost every day. However, we also install single-ply roof systems (TPO, PVC, EPDM, KEE), modified bitumen roof systems, and foam and coatings. Flat roof systems are in Arizona, however, there aren’t very many roofing contractors that truly know how to properly install a flat roof.

Behmer Roofing has over 35 years of installing all types of flat roof systems throughout the state of Arizona - both on residential homes and commercial buildings alike. Give us a call today to have us inspect your flat roof.

Types of Flat Roofs

Built up flat roof in Phoenix

Built-Up Flat Roofing - BUR

The most common type of flat roofing - built-up (“BUR”) utilizes hot asphalt and multiple alternating layers (“plies”) of various types of roofing felt combined together to create a long-lasting, easy-to-maintain, roof system. Due to the extremely dangerous nature of this roof system, only hire an experienced roofing professional to install built-up roof on your home or commercial building. Behmer Roofing has been installing BUR roofs for close to 80 years!

Single ply roof in Sedona


Single-ply roofing refers to multiple types of membrane roofing, spefically TPO, PVC, EPDM, and KEE. As opposed to BUR, single-ply is one layer of rubberized polymer membrane heat-welded or glued together. Single-ply is a great option for your flat roof.

Bitumen roof in Phoenix

Modified Bitumen

Modified Bitumen roofing is a type of built up roofing where the sheets are modified with a rubber polymer mixed into the asphalt. Mod-Bit can be hot-applied, torch-applied, or cold applied. Mod-Bit is typical an SBS or APP polymer, and is more expensive than traditional built-up roofing.

SFP roof in Sedona

Spray Polyurethane Foam (SPF)

Spray Polyurethane Foam (SPF) is a material that is sprayed as a liquid so it can expand into a foam, creating a solid layer across an existing roof. The foam is then coated with an acrylic or silicone top coat.
