A hybrid roofing system that is derived from built up roofing techniques combined with advanced roofing technology, modified bitumen roofing material is made up of high quality polymers reinforced with one or more layers of heavy duty polyester or glass fibers that offers superior strength and long lasting performance.
As the name suggests, special modifiers are combined with standard roofing asphalt during a controlled refinement process where bitumen is then reinforced with fiberglass or polyester fiber to form sheets that provide superior strength and durability. Certified A Roof Above roofing experts offer two types of modified bitumen roofing materials:
SBS (Styrene Butadiene Styrene)
Installed with hot mopping of a cold adhesive onto asphalt, this type of modified bitumen roofing can be further reinforced with an adhesive backing that provides a rubber type finish.
APP Atactic Polypropylene
Classified as a torch on roofing technique, APP modified bitumen is comprised of a thermoplastic polymer that is installed with heat applied applications (torch on or heat welded) that result in a smooth plasticized finish.
Available in rolls or sheets, modified bitumen roofing material is specifically manufactured to provide uniform thickness and state of the art components that are spread evenly throughout the material and carefully layered over the roof membrane. As esthetically appealing as they are practical, A Roof Above offers modified bitumen roofing systems in several granular color surfaces that offer excellent UV protection.
Our licensed and experienced roofing technicians combine one or more layers with additional built up roofing materials and techniques that result in flawlessly customized installations tailored specifically to the structural requirements of your commercial property.
What Are the Benefits of Modified Bitumen Roofing?
Recommended for commercial buildings of any size or dimension, A Roof Above provide licensed roof inspections and certified modified bitumen membrane roofing installation that are industry endorsed due to the following benefits:
Modified Bitumen systems have been known to last up to 20 years or more with minimal maintenance.
Exceptional Strength and Durability
Modified polymers stand up well to extreme temperatures hot or cold.
Heavy Duty adhesive incorporated into modified bitumen installations prevent water infiltration.
An extra insulation layer locks in heat.
In addition, the superior strength of both types of modified bitumen roofing material make then highly impact resistant and long lasting. Typically installed and ideal for low sloping roofing systems, A Roof Above installations ensure that water pooling is limited to minimize any form of water damage. Easy to install, a modified membrane roofing system is best carried out by a professional and certified roofer experienced with built up roofing techniques.
Ideal for New Builds, Roof Restoration or Re-Roofing Projects
An ideal roofing option for roof repairs for existing built-up roofing membranes, A Roof Above also recommends modified bitumen roofing for new commercial constructions where long lasting and exceptionally weather resistant performance is required.
