Flat Roof Contractor Minneapolis MN – Built-Up Roofing (BUR) MN
Built Up Roofing “BUR SYSTEMS”
Built-up flat roofing has been used for more that 100 years and is extremely durable. BUR offers the added protections of redundant multiple layers, performs well in extremes of heat, cold, wind, and snow, is easy to repair, and has a proven track record.
BUR’s simply last longer because each ply of built-up roofing system contains a mat of glass fiber reinforcement. When multiple plies are combined and sandwiched between layers of water-resistant asphalt, the result is a longer lasting roof. Surfacing for built-up roof systems include aggregate (such as gravel, slag or mineral granules), glass-fiber or mineral surfaced cap sheets, hot asphalt mopped over the entire surface, aluminum coatings or elastomeric coatings. By using an ultra long lasting product, you could be adding five to ten years of life to your roof.
The Benefits From A Built-up Roofing System
- System Longevity
Each ply of a Built-Up Roofing System contains a mat of glass fiber reinforcement while most single-ply systems contain no reinforcement at all. When multiple plies are combined and positioned between layers of water-resistant asphalt, the result is a longer lasting roof.
- Easy and economical to maintain. And if necessary, can be repaired with conventional, time-proven materials, resulting in extended service life.
- Product and material improvements have enhanced an already high-quality system.
- Limited Roof Movement
All roofs expand and contract, especially in the cold weather states. A Single-ply roof typically responds by elongating its infrastructure. Over time single-ply systems can lose their elasticity, resulting in buckling, ridges and splits. A Built-Up Roof, however, dramatically limits movement with a high tensile strength in excess of the recommended 200 lbs./sq.in. Fracturing is essentially all but eliminated, and the Built-Up Roof will last longer. A larger critical mass enables the roof to tolerate surface punishment
- Superior Water Resistance
It’s simple, multiple layers of reinforcement offer more protection thus reducing the risk for leaks, whereas, a single-ply membrane only offers one chance at preventing a leak. Additionally, nothing compares to asphalt when it comes to making a roof water resistant. Asphalt is the glue that holds a Built-Up Roof together. It seals and protects the entire roof, delivering up to five times greater water-resistant thickness.
- Easier Installation
In the case of hot Built-Up Roofs, the multiple plies get joined/fused together using hot-mopped asphalt to create a monolithic barrier. Every inch is firmly and completely adhered over the entire roof area, without the need for ballast or fasteners. Single-ply systems require ballast or fasteners because they are generally laid loose. But ballast (such as stones) increases structural load and can be blown off by strong winds. Fasteners can also create less stress points and additional opportunities for moisture leakage.
It’s simply an issue of protecting your investment. When compared to the potential cost from damage of a poorly installed single-ply roof, the cost of a Built-Up Roofing System is minimal. You need to protect your business and your investment, so make sure the investment you make is with a quality commercial roofing system that can stand the test of time.
