Modified Bitumen (Mod-Bit) Roofing, Explained

Modified Bitumen (MB) roofing is an asphalt-based roofing system closely related to the Built-Up Roofing (BUR) design. This roofing material is suitable for buildings with low-scope or flat roofing. MB roofing originated in Europe in the mid-1960s and was adopted widely as a commercial roofing material across the US. Engineered MB roofing material is popular because it performs optimally in harsh conditions, including cold weather. Mod-bit roofing consolidates into typically three to five layers of roofing components, making it one of the most trusted and durable flat roofing systems. The elements making up the modified bitumen roofing system include: Insulation. This feature provides thermal resistance or the “R” value for temperature stability. It also provides a solid surface for the new roof system to be installed over.  Modified Base Sheets. Base sheets are critical foundations for flat roofs; cap sheets offer redundancy when other layers develop a support problem. This is the first ply installed. Modified Bitumen Mid Ply Sheets. These are factory-fabricated sheet membranes composed of co-polymers reinforced with fiberglass or polyester. These are typically installed on plys 2-4 Modified Cap Sheet. The top sheet that is typically installed with granules. This sheet provides weathering resistance or UV protection. This is the top ply installed, and what most people see what they look at a modified roof. What makes mod-bit roofing a suitable roofing […]

Flat roofs are among the most common and versatile types of roofs globally. While they are not the most glamorous and enchanting option, they have unique advantages.

Cost The cost of a flat roof system can vary dramatically. If you need to complete a full tear off, you also need to install code-compliant insulation, which can add dramatically to the cost. There are also big cost differences between the products available (TPO, EPDM, PVC) and how they are installed (Fastened, adhered, etc). Make sure you do your homework and know what you are getting before approving a proposal. 2. Maintenance On a flat roof system, maintenance is very important.
