Bitumen Flat Roof Installation in Milwaukee

Durable Bitumen Roof System Options for Wisconsin Commercial Buildings

Bitumen roofing materials are strong and weather resistant, making them a popular choice for flat (low slope) roofs. Bituminous roofing systems include built-up roofs and modified bitumen membranes. Modified Heat Applied Bitumen Roofing bitumen can also be applied as a cap sheet on top of a built-up roof.

Bitumen materials provide superior waterproofing and insulation on commercial flat roofs and are able to endure the extreme cold of Wisconsin winters.

Built-Up Roofs (BUR)

Built-up roofs consist of layers of plies (felts) laminated on site with bitumen to form the roof membrane. The reinforcing felts give strength and stability to the roofing system, preventing localized stress. Bitumen (asphalt) works as both the adhesive and an effective waterproofing agent. A surfacing layer (usually gravel or a pigmented coating) adds UV protection and fire resistance.

Built-up roofing is constructed in the field (as opposed to factory-made membranes). Infinity Exteriors is Wisconsin’s best commercial roofing contractor for BUR construction and repair.

Modified Bitumen Roofing

Modified bitumen roofing materials have been in use since the mid 1970s in the U.S. To create modified bitumen (MB), modifiers such as rubber or plastic polymers are added to standard roofing asphalt.

Modified bitumen membranes can be applied to anything but DensDeck and polyisocyanurate insulation, making modified bitumen an exceptionally versatile roofing system. The two most common types of modified bitumen are:

SBS Modified Bitumen Roof Membranes are manufactured by modifying bitumen with synthetic rubber polymers.
APP Modified Bitumen Roof Membranes are manufactured by modifying bitumen with plastic polymers.

Modified bitumen membranes consist of polymer-modified asphalt reinforced with one or more plies and can also include a factory-applied surfacing material.

Bitumen Roof Life Expectancy

When properly installed by a bitumen flat roof specialist, bitumen roofing systems typically last at least 20 years. Quality bitumen membrane manufacturers provide lifetime warranties on roofing systems.

The commercial roofers at Infinity Exteriors keep your manufacturer’s warranty valid and extend the life of your bitumen flat roof with expert installation, maintenance and repairs done according to manufacturers’ exacting specifications.

Bitumen Cap Sheets

Modified bitumen cap sheets have reflective granules to reduce heat gain and improve energy efficiency. Use of an SBS or APP modified bitumen cap sheet eliminates the need for a field-applied liquid coating on new flat roof installations.

Bitumen cap sheets protect lower layers of a BUR or act as the surface ply in 2-ply modified bitumen roofing systems. Cap sheets can also be used in reroofing and retrofit applications to extend the life of an older roof or improve thermal insulation.
