These types of flat roofs are the most common for commercial buildings. Though they share the same structural components, some differences will make one a better fit for your business and budget over the other. BUILT-UP ROOFING Built-up roofs (BUR) have been in use in the United States for over 100 years. They’re traditionally made with a smooth stone, layers of waterproof material and hot tar, and a topcoat of gravel or fiberglass. The more layers there are, the higher the quality of the materials used, the more resilient it will be. Excellent Thermal Performance, Resulting In Noticeable Reductions In Heating & Cooling Costs Withstands High Traffic Fire, Uplift, & Weathering Resistance Attractive Below Windows & Decks Cheapest Of The Two Multi-Layer Protection Reduces Chances For Leaks Suitable For All Types Of Decks MODIFIED BITUMEN ROOFS European roofing companies developed modified bitumen roofs(MB) in the 1960s. American and Canadian roofers have used them since 1975. Some MB types are installed with a torch-application method, like BUR, while others are applied with “cold” adhesives. MB is a factory-made membrane of asphalt and plastic or rubber polymers fused to a reinforcing underlayer. Companies often sell MB in rolls that roofers later cut into custom-fit sheets. MB has the inherent redundancy of layered asphalt and the flexibility and UV resistance of a polymer-based membrane. MB has a mid-range price. It’s flexible enough to adapt to any configuration. MB has a competitive life cycle cost. It has superior waterproofing characteristics. It is available with flame-free and VOC-free installation. MB has high tensile strength, making it highly tear-resistant. Its light-colored mineral surface reflects heat and cuts energy bills. WHEN TO INVEST IN REPAIR OR REPLACEMENT Flat roofs typically carry a 10 or 20-year warranty. Like any other kind of roof, BUR and MB will last longer if they are correctly maintained. Commercial roofers report that a well-maintained BUR can stay in excellent condition for as long as 40 years. The biggest problem that flat roofs face is pooling water. A frequent cause is drains, scuppers, and gutters clogged by loose gravel and storm debris. The faster the water is removed, the less likely it will leak or suffer damage from the excess weight.

Very nice people to work with! We were impressed when one of the guys pointed out that he accidentally dropped 2 nails in the neighbor's driveway and didn't want to cause a flat tire. Compare this to my neighbor's roofers who shot nails out all over the next door's driveway, then refused to pay for the flat. Will definitely refer them." Valerie B.
