Flat Roofs

Horizontal Roofs

Although it is called “flat roofing,” it is not actually flat. In fact, we lay out the roofing to where it has a very mellow slope — between ¼ to ½ inch per foot — so that it drains water effectively. Such a low slope holds water and snow significantly longer than more common steeply-pitched roofs. Because of that, flat roofs need a different material to stay watertight, especially during those North Shore snowstorms! Standard sloped roofs usually have shingles that overlap them like fish scales, while a flat roof is designed as a continuous surface that can withstand water for a certain amount of time.

Flat Roofs

Single-Ply (EPDM Rubber)

There are several types of single-ply roofing materials available, but the most common for residential roofing is EPDM roofing. EPDM stands for ethylene propylene diene monomer. This is just fancy talk for a rubber that is made to provide excellent electrical insulation and is one of the best water-resistant rubbers available. The strong weather resistance that this rubber provides makes it ideal for flat roofing in the North Shore area!

Benefits of Single-Ply roofing include:

  • Maintenance is simple and inexpensive
  • Roof deck doesn’t need reinforcement because EPDM roofing is lightweight
  • Leaks are extremely rare

Modified Bitumen Roofing

Modified bitumen roofing (MBR) is a flexible, asphalt-based material with a mineral coating. You could compare this type of roofing to our asphalt roofing. MBR is simple to install and is known to be low-maintenance and is very durable.

Benefits of MBR Roofing Include:

  • MBR can be recycled
  • Simple to install
  • Factory-applied mineral surfacing assures persistent installation

Built-Up Roof Systems

Back in the day, built-up roofing (BUR), was the most frequent system of flat roofing before single-ply and MBR were developed. BUR roofing inheres many layers: a bottom layer of insulation board, multiple layers of tar or asphalt with layers of roofing felt, and then a top layer of gravel on top. This recipe results in a thick, seamless roof that is highly durable.

Benefits of BUR Roofing Include:

  • Incredible protection from the elements
  • Low-maintenance
  • The gravel makes it highly resistant to foot traffic
