Why Modified Bitumen Roofing?
Modified bitumen combines asphalt with polymer modifiers and reinforcing fabrics to create a multi-layered membrane that holds up against UV rays, thermal expansion, foot traffic, and standing water. It can be installed using torch-down, cold adhesive, or self-adhering methods, and is especially effective on low-slope or flat commercial roofs. We begin with a thorough assessment of your current roof and building needs. Whether you’re repairing problem areas or replacing an outdated system, we tailor the installation to your property’s structure, climate conditions, and budget.
A Full Range of Modified Bitumen Roofing Services
Before and after installation, we take care to ensure performance, code compliance, and minimal business disruption. We can also provide guidance on other potential options if you’re looking for information on the best commercial roofing or flat roofing solutions for your needs. Our full range of services includes:
- Roof inspections and condition assessments
- Leak detection and membrane patching
