What Is Modified Bitumen Roofing?

  • Asphalt with polymers added. The polymer keeps the asphalt flexible in cold and stable in heat.
  • Reinforced sheets. Each roll has a fiberglass or polyester mat inside.
  • Two plies or more. A base sheet goes down first and a cap sheet goes over it. A 2-ply roof is one base and one cap.
  • SBS. Rubber-modified asphalt. It stays flexible and takes hail and building movement.
  • APP. Plastic-modified asphalt. It resists heat and sun, and crews torch it down.

How Is Modified Bitumen Installed?

  • Torch-applied. A torch melts the back of the sheet onto the layer below.
  • Cold-applied. Adhesive bonds the plies. No open flame on the roof.
  • Self-adhered. Peel-and-stick sheets for buildings where flame and fumes are a problem.
  • Hot-mopped. Hot asphalt between plies, the traditional method for SBS.
  • Staggered laps. We offset the seams of each ply so no seam sits over another.

What Does a Modified Bitumen Roof Look Like?

A finished modified bitumen roof looks like wide strips of rolled roofing with a gritty surface. The grit is mineral granules, like the surface of a shingle, in white, gray, tan or black. Some cap sheets are smooth and get a reflective coating. Expect about 20 years from the roof, and more if you keep the surface and the drains maintained.

What Fort Worth Clients Say About Texcore Construction

Common Questions

SBS adds synthetic rubber to the asphalt, so the sheet stretches and recovers. APP adds plastic, so the sheet resists heat and sun. SBS suits hail and building movement. We recommend one after we see the roof.

About 20 years, and some reach 30 with maintenance. Standing water, lost granules and open laps cut that short. A roof coating can add years to a cap sheet that is worn but dry underneath.

One base sheet and one cap sheet, bonded together. The second layer backs up the first if something cuts the top sheet. Three-ply systems add another base sheet for roofs with heavy foot traffic.

Both. We patch blisters, splits and open laps and rebuild flashings on a commercial roof repair. If water has soaked the insulation across the roof, replacement is the better spend. Compare other systems on our flat and low-slope roofing page.
