Modified bitumen roofs are made of polymer modified bitumen membranes applied using heat to secure the seams between runs of roofing material, giving the system its strong and durable protective layer. And due to their low-maintenance requirements, modified bitumen roofs are among the most installed materials in commercial roofing today.
Modified Bitumen Advantages
Opt for modified bitumen roofing and you can enjoy:
- Lasting performance. Modified bitumen membranes are reinforced with multiple plies of fabric, including polyester, fiberglass or a combination of both. While traditional sheeting rolls may start experiencing problems after a 10- to 15-year period, modified bitumen membranes can last more than 20 years without requiring too much maintenance.
- Superior weather protection. The polymer modification involved in the material’s manufacturing process makes this roofing system more durable and flexible. This translates to modified bitumen systems effectively with standing intense heat, cold and UV radiation, making sure everything inside your building is well-protected. The commercial roofing option can also protect against damage due to impact and high foot traffic.
- Versatile installation methods. Modified bitumen systems can be installed using one of numerous methods: cold applied, hot applied, heat-welded or self-adhered. This material is sold in rolls, with seams sealed using a torch to heat the underside of the bituminous material, which coats the sides of the reinforced mat.
- Cost-effectiveness. Modified bitumen roofs offer great value for your money primarily because they are easy to install and require minimal maintenance. This makes them an excellent choice for building owners who want to save money in the long run.
- Thermal resistance. To increase a building’s comfort and energy efficiency, modified bitumen roofing makes use of an insulation layer to boost thermal resistance, blocking excess heat from being absorbed into the building to promote a cooler interior atmosphere. Additionally, it features a reflective surface to further keep passive heating at bay.
Did You Know?
Before modified bitumen roofing was introduced, large commercial buildings used heavy-gravel surfacing as part of built-up roofing systems to serve as protection against UV rays. Because modified bitumen membranes adhere directly to the substrate, they don’t require surfacing with gravel, lessening weight strain on roof supports.
