Asphaltic Roofing

Why Asphalt

Asphalt has a longer history of providing durable, high quality roof systems for the commercial roofing market than any Single-Ply or Coating technology on the market. Why? Redundant waterproofing layers, several installation options, several system type options, and a wide range of code approvals are just a few of the reasons.

Installation Options

Asphalt systems offer contractors a wide variety of installation options including Hot Asphalt, Cold Adhesive, Torched, and Self Adhered.* This variety of installation methods allows asphalt systems to provide reduced labor cost options, a wide installation temperature ranges, easy-to-install options, high-performance system options, and even options to combine Asphalt with certain Single-Ply products.



Redundant Waterproofing Layers

Commercial asphalt roofing systems are comprised of two or more waterproofing layers. This redundancy provides building owners with enhanced waterproofing protection. On top of excellent waterproofing protection, the redundant layers of asphalt help provide enhanced puncture resistance from foot traffic and roof-top debris.**

System Types

Asphalt system options include Built-Up Roofing (BUR), as well as APP and SBS Modified Bitumen Roofing (MBR). 

Built-Up Roofing (BUR)

  • Built-Up roofing is the very traditional roof system comprised of several layers of hot asphalt with asphalt-saturated ply sheets installed in the hot asphalt at each layer.
  • Although it is one of the "oldest" roof system, it still provides great waterproofing protection with its multi-layer construction.

APP (Atactic Polypropylene) Modified Bitumen Roofing

  • APP is a plastic modified asphalt sheet that provides excellent durability and high heat resistance.
  • APP is typically applied using a torch to heat the bottom of the APP roll and provide a fully adhered asphalt roof system.

SBS (Styrene-Butadiene-Styrene) Modified Bitumen Roofing

  • SBS is a rubber modified asphalt sheet that provides excellent flexibility to conform to substrate irregularities.
  • SBS is traditionally applied by hot asphalt or cold adhesive, however there are also SBS systems that are applied with a torch.
  • Most self-adhered asphalt membranes are SBS, providing contractors the flexibility of SBS with a very fast, easy-to-install option for an SBS roof system.
