Introduction The application of any roofing system during cold weather poses special challenges. Specific to modified bitumen materials, these challenges can include maintaining proper sheet material, adhesive, and asphalt temperatures at the point of application. Cold temperatures may stiffen sheet materials, reduce the curing or flash-off rate
Read more →Self-adhesive (SA) modified bituminous membranes provide an effective finished roof when properly installed. These systems combine the long-term, proven performance of modified bitumen sheet materials with installation advantages imparted by a self-adhesive bituminous layer. Product Description, Manufacturing Process and Governing Standards Self-adhesive modified bituminous membranes are comprised
Read more →Built-Up Roofing (BUR) membranes have been in use in North America for more than 100 years. BUR systems predominately consist of alternating layers of asphalt (bitumen) and fiberglass ply felts that create a very durable water-resistant membrane. The number of plies within a cross-section of the system

Specific to built-up roofing systems, these challenges can include maintaining the proper asphalt temperature at the point of application, slower cure time of cold-applied adhesives, and increased stiffness of roofing materials.
Read more →Introduction The Asphalt Roofing Manufacturers Association (ARMA) recommends that the structural roof deck meet certain minimum requirements to be an acceptable substrate for the specified roofing system. Generally, all decks should be clean, dry, and securely fastened to the building structure with no abrupt level changes exceeding

The International Agency for Research on Cancer (IARC) is an arm of the UN’s World Health Organization, headquartered in Lyon, France. One of IARC’s missions is to develop detailed scientific reviews (called “Monographs”) of the potential
Read more →For commercial buildings, asphaltic low-slope roofing provides the highest level of quality, affordability and reliability on the market. Most commercial facilities use low-slope roofing because it is cost-efficient, maximizes usable space and can be designed to feature value-adding amenities such as HVAC equipment or a roof garden. Though a flat roof may
