Built Up Roof System
Comprised of multiple layers of asphalt and fiberglass mats or felt, a Built Up Roof system, or BUR, is a popular asphalt roofing system that works with a variety of different property applications. The layers of felt and asphalt provide a durable exterior, protecting your property from water and extreme weather. A top layer of stone aggregate offers an additional layer of protection to the system. BUR systems have been used for many years and are a time tested solution.
Modified Bitumen Roof System
Similar to a BUR system, a Modified Bitumen
system is made up of asphalt sheets with modifiers to increase flexibility and are reinforced with polyester or fiberglass matting, increasing the strength of the system and making it more durable than the BUR roofing method. These systems can be applied with either hot or cold asphalt adhesive. The top layer will have a granular layer or acrylic coating to protect the roof system from UV and increase reflectivity, reducing heating and cooling costs.
