Modified Bitumen roof systems are asphalt based and provide superior waterproofing features. The typical life span for this kind of system is about 10 to 20 years. Modified Bitumen roofs are usually installed as a two ply system and are always fully adhered.

These roof systems are made up of asphalt which has been modified with a polymer to create properties similar to plastic or rubber. The modifiers provide increased resistance to brittleness, cold temperatures and also provides increased elasticity and strength.

There are numerous surfacing options for APP and SBS modified roofs including factory applied mineral surfaces, gravel surfaces, smooth surfaces, and “cool roof” coatings, which are highly reflective coatings that can help save on cooling costs.

Modified Bitumen (MB) roofing is an asphalt-based, close cousin of the Built-up-Roof (BUR) designed for buildings with low-slope or “flat” roof structures. Engineered modified bitumen roofing membranes originated in Europe in the mid 1960′s and have been used successfully in the United States and Canada since approximately 1975.

a polyester mat reinforces the APP modified asphalt and is then manufactured into a roll product. The membranes have extra asphalt on the back side which allows it to adhere to the substrate through applications such as heat welded or torch applied methods.
  • Torch Applied – An open flame torch melts the APP modified membrane to the bottom side of the sheet as it is being applied.
  • Heat Welding – The welder is used to blow out hot air that fuses the rear of the membrane to the substrate when it is applied. This method is a safer then torch applied, as it is much less of a fire hazard.
  • Hot Asphalt application – Hot Asphalt is applied to the felts or substrate with the use of a machine. It can also be physically mopped down. Either way, the membrane is laid over the hot asphalt. The hot asphalt acts as the adhesive and allows the membrane to bond to the substrate.
  • Cold Adhesive – The modified membrane is set in a cold process using specially formulated asphalt based adhesives as it is being applied.
  • Self Adhered – The bottom surface of the membrane is covered with an adhesive and release paper. Once the paper is removed, the adhesive allows the membrane to adhere to the substrate without the use of additional adhesives.
