Modified Bitumen Roofing
A cost effective and proven method for flat roof or low slope roofing systems options.
Modified Bitumen roofing is closely related to built-up roofing systems in that materials are layered on top of each other for combination high-performance protection. Originating in Europe in the 1960’s and adopted in North America by the 1970’s, modified bitumen roofing systems have been around long enough to prove themselves as cost effective for flat roof or low slope roofing systems options.
When installing a modified bitumen roofing system, layers of materials are applied: insulation, modified plies, modified bitumen membranes, adhesive and lastly, surfacing.
Benefits of Modified Bitumen Roofing Systems
Each layer provides a level of thermal resistance, strength, waterproofing, UV protection and weather resistance.
Modified bitumen roof systems typically last 20 years with no maintenance; however, quality manufacturers will provide lifetime warranties on their systems.
Modified bitumen systems are fairly quick to install with lower labor costs and quick turn around times for installation.
