Modified Bitumen Roofing Specialists

One of the longer-lasting options for flat roofs is bitumen roofing or a modified bitumen roof. Modified bitumen is a type of asphalt product that can be applied in a number of ways to the roof in both hot and cold temperatures. Modified bitumen roofs have a lot of advantages over other types of membrane roofing, and are often seen as the modern alternative to the built up roof.

Installing a modified bitumen roof requires a high level of expertise and attention to detail to ensure the roof is properly sealed and water-resistant. Here are the steps we follow when installing a modified bitumen roof:

  1. Clean the surface: Before installation, we ensure that the surface is free of debris and dust. If necessary, power-wash the surface and let it dry completely.
  2. Measure and cut the membrane: Measure the area to be covered and cut the modified bitumen membrane to size. Make sure to allow for some overlap at the seams.
  3. Apply adhesive: Apply adhesive to the surface using a roofing brush. Work in small sections to prevent the adhesive from drying out before the membrane is installed.
  4. Roll out the membrane: Carefully roll out the modified bitumen membrane onto the adhesive, making sure to smooth out any wrinkles or bubbles.
  5. Seal the seams: Use a hot-air gun to heat-seal the seams, ensuring a watertight seal. If necessary, use a roller to further smooth out the seams.
  6. Install flashing and edge details: Install any necessary flashing and edge details to further seal the roof and prevent water infiltration.
  7. Finish with a protective coating: Finish the roof with a protective coating, such as a reflective coating, to increase its durability and lifespan.

It’s essential to follow the manufacturer’s instructions and local building codes when installing a modified bitumen roof. Additionally, it’s best to hire a professional roofing contractor with experience in installing modified bitumen roofs to ensure the job is done correctly and to avoid any potential issues down the line.

Modified Bitumen Flat Roof Repair

Are you looking for repair of modified bitumen on your commercial flat roof? Our experienced in-house team will pinpoint the problems, walk you through the solutions and provide thorough, long-lasting fixes for all your modified bitumen troubles.

Modified bitumen roofing can be repaired in several ways, depending on the type and severity of the damage. Here are some standard repair methods we use:

  1. Patching: For small holes or tears, roofing professionals may use a patching material, typically made of the same material as the modified bitumen roofing, to cover the damaged area.
  2. Coating: A specialized roof coating may be applied to the surface of the modified bitumen roofing to seal small leaks or cracks.
  3. Heat welding: For larger areas of damage or seams that have come apart, roofing professionals may use heat welding to fuse the modified bitumen roofing together. This involves using a specialized tool that heats the roofing material, allowing it to be fused back together.
  4. Replacement: In cases where the damage is severe or the roof is nearing the end of its lifespan, the damaged section of the modified bitumen roofing may need to be replaced entirely.
