What is BUR

You could say BUR Roofing Systems invented the game. Having been implemented for over 100 years, this is the most battle-tested system here or anywhere. Predominantly known for its redundancy — meaning its 4+ plies offer multiple layers of protection — and its brag-worthy high-puncture resistance and long-term weather and waterproofing, there’s no system more proven or reliable. There are a variety of different types, including smooth asphalt, ballasted, and cold built-up, each with its own applications, settings, and construction compatibilities.

How are Built-Up Roofs Installed on Commercial Properties?

      • With traditional hot-applied built-up roofing, an asphalt kettle is required to heat and maintain the asphalt at its specified application temperature. Multiple plies of felt are mopped in an overlaying lap fashion (hence built-up), adhered to each other with black hot asphalt.
      • The top layer of a built-up roofing system can vary but typically includes either a modified bitumen cap sheet or a flood coat with gravel surfacing.
      • A modified bitumen cap sheet can appear as either granule surfaced cap (appearing to be much like the modified roofing products), a smooth cap with a protective coating (silver paint, or elastomeric roof coating), or a gravel surface.
      • Cold applied built-up roofing installations are applied in much the same manner as a hot-applied roof, but with cold-applied (usually asphalt-based) adhesive in lieu of hot asphalt.

  • What is EPDM Roofing and How Much Does It Cost?

    EPDM roofing, or more formally “Ethylene Propylene Diene Monomer” roofing, is a type of single-ply roofing membrane that has remained a popular, time-tested staple of the commercial roofing industry since the 1960’s. EPDM is readily available and relatively straightforward to install, meaning less labor costs than other more complex roofing systems. Thanks to its traditional installation options and easy repairs/maintenance, it’s an economical roof option with lifespans that can exceed 30 years.
