Built-up roofing is an extremely popular option for commercial roofing, particularly on low-sloping roofs. Cold applied roofing systems are a type of built-up roof that are assembled using solvent-borne liquid adhesives.

  • Base Sheet – Fiberglass, asphalt coated organic sheets, or asphalt coated venting sheets
  • Felts/Fabrics – Coal or tar-saturated felt, cotton, or burlap
  • Bitumen – Asphalt, coal tar, or lap cement
  • Surfacing Component – Gravel, asphalt, or mineral coating.

The cold process helps create a seamless, waterproof roof. This type of roofing is popular in confined, urban spaces, which often have numerous roof penetrations and restrictions on hot asphalt or heat welding. Cold Process Built-up roofing systems are easily applied by cold-applying the covering, then fast-curing for long-lasting protection.

Cold applied built-up roofing systems are applied without kettles or the disagreeable odor associated with hot applications. This roof coating is a more economical option that is easy to use and has a longer lifespan than other coating options.
