Modified Bitumen Roof: An Advanced Flat to Low-Slope Roofing System
Modified bitumen is a roofing material that is suitable for flat and low-slope commercial roofing in Dallas. Do not confuse it with the traditional BUR system. Modified bitumen is made up of a mixture of rubber additives, plastic, and asphalt. Moreover, the materials get layered between sheets of either fiberglass or polyester roofing felt then finished with a cap sheet or aggregate.
We use modified bitumen on commercial roofs in Dallas for many reasons, especially for its superior tear resistance. The polyester and fiberglass reinforcement layers are responsible for making the material so effective.
Components of Modified Bitumen Roof Systems
The elements of bitumen are unique and influence its overall desirable quality as a roofing material. A modified bitumen roofing system consists of a five-layer roofing component combination.
- Insulation – Used to provide “R” value, or thermal resistance, for temperature stability of the roof system.
- Modified Base Sheets or Plies
- Modified Bitumen Membranes – Factory fabricated sheet membrane composed of co-polymer reinforced with polyester or fiberglass roofing felt
- Adhesive – Waterproofing material with a bonding agent applied either hot or cold
- Surfacing – Provides UV protection and weathering resistance
Modified Bitumen Manufacturing Method
The roofing asphalt is distilled, and the plasticizers are removed in the process. Modifiers and then added to it. To increase strength and durability, experts use fiberglass or polyester to reinforce bitumen.
There are two types of modified bitumen. The first one is the SBS (styrene-butadiene-styrene) modified. SBS is designed to increase the membrane’s flexibility and give the standard roofing material stronger contraction and expansion capabilities.
The other type is APP modified. APP (atactic polypropylene) increases the lifespan of this commercial roofing system.
Since the SBS rubber increases the flexibility of bitumen, it is often the most popular option.
