Flat roofing is not actually flat; it has a very low slope—between 1/4 to 1/2 inch per foot—so that it drains water. But such a low slope holds snow and water much longer than a steeply pitched roof and therefore needs a very different material to stay watertight. While standard sloped roofs typically have shingles that are overlapped like fish scales so that water slides over them, a flat roof is designed as a continuous, or monolithic, surface that can hold some standing water for a limited time.

There are three main types of flat roof systems: 

  1. Built-up roofing (BUR)
  2. Single-ply (TPO, PVC)
  3. Modified bitumen (MBR)
    Built-Up Roofing (BUR)

Built-up roofing
(BUR) was the most common type of flat roof before modified bitumen and membrane roofing were developed. BUR consists of many layers: a bottom layer or two of insulation board, multiple intermediate layers of tar or asphalt alternated with layers of roofing felt, and a top layer of gravel. The result is a thick, tough, seamless roof assembly that is highly resistant to damage.

While built-up roofing is still used in some commercial applications, it is not a common roof type for houses, primarily due to is weight and thickness as well as the strong odors and mess it creates during installation.

Single ply membrane 

Flat roof membranes are used in both residential and commercial roofing projects. In residential, it is used predominantly for large apartment buildings, garage roofs, and small extensions. It is also increasingly used for larger main roofs in single-family housing with modern designs that integrate flat roofs.

Most large commercial projects such as apartments, warehouses, sports facilities, schools, and hotels utilize membrane roofing on flat roofs. Most of these commercial buildings require roof access for mechanical systems or they have occupied roof terraces, making membrane roofs an ideal cost effective solution.

The two most common types of flat roof membranes are TPO and PVC.

Thermoplastic roof systems use TPO (thermoplastic polyolefin) or PVC (polyvinyl chloride) membranes. Both materials provide excellent weathering performance and are highly resistant to UV, tears, punctures, and most chemicals. Thermoplastic membranes are seamed using hot air welders to melt the plastic and pressure to join sheets together.

 Modified Bitumen Roofing

Modified bitumen roofing (MBR) was developed in the early 1960s as a lighter-weight alternative to BUR. It also comes without much of the mess, heat, and smell associated with installing BUR. Modified bitumen roofing is a flexible, asphalt-based material with a mineral top coating, similar to traditional asphalt shingles. It comes in rolled sheets that are 3 feet wide and up to 36 feet long. The sheets are rolled onto the roof atop a base sheet membrane.

The conventional method of installation, called “torch-down,” involves heating the backside of the roofing as it is unrolled, essentially melting the material to the base layer. There are also self-adhesive versions of modified bitumen that install in a peel-and-stick fashion.
