BUR is used on flat and low-sloped roofs and consists of multiple layers of bitumen and ply sheets. Asphalt products include shingles, roll-roofing, built-up roofing, and modified bitumen membranes. Modified bitumen membranes are hybrids that incorporate the high-tech formulation. Thermoplastic membranes are identified by seams that are formed using either heat or chemical welding. The green roof was more effective in reducing heat gain than in reducing heat loss.

Information about green roofs at GSA can be found on the agency’s Green Roof Tracker. Are environmentally friendly. Although material and installation costs are higher for concrete and clay tile roofs, when evaluated on a price-versus-performance basis, they may out-perform other roofing materials.

Concrete and clay tile roofing systems are also energy-efficient, helping to maintain livable interior temperatures (in both cold and warm climates) at a lower cost than other roofing systems. Concrete and clay tile roofing systems are durable, aesthetically appealing, and low in maintenance. Tile roofing systems are made from naturally occurring materials. For homes in the Ottawa, Ontario, Canada area contact a certified professional Ottawa roofing company. Are typically seen in many traditional homes across the United States.
