Compare These Commercial Roofing Materials

Commercial roofing products are so plentiful and varied that business owners can easily become confused by the many flat roof materials available. Three common roofing materials offered by Beldon Roofing are single ply, built-up, and modified bitumen. 

Single Ply

Single ply roofing is one of the most durable of flat roof materials. Typically, polyvinyl chloride (PVC) vinyl, ethylene propylene diene terpolymer (EPDM) and thermoplastic polyolefin (TPO) are the mainstays of single-ply roofing. 

Beldon Roofing deals with major manufacturers in single-ply: 

  • Carlisle SynTec Systems—PVC, TPO and EPDM
  • Duro-Last—PVC
  • Firestone—EPDM and TPO
  • GAF—TPO
  • Johns Manville—TPO, PVC and EPDM
  • Sika Sarnafil—PVC

Single-ply membranes follow roofline curves and transitions between slopes. They can overlay existing roof without tear-off. They offer:

  • Superior durability
  • Environmental sensitivity
  • Quick installation
  • Excellent waterproofing

Single-ply membranes are generally more expensive than BUR and normally on a par with modified bitumen. 

Built-Up Roofing (BUR)

One of the oldest and least expensive flat roof materials is BUR, where your commercial property’s roof is built up in layers of felts or reinforced fabrics saturated with bitumen (asphalt, or coal tar pitch). A roof might have four or more layers, laid crosswise to each other, for maximum weatherproofing and durability. Usually the finished surface is topped with gravel ballast or a spray coating to ward off premature weathering. 

BUR flat roof materials are ideal for residential use because they do not require a large investment in the material, can be sized to any job, and are very inexpensive. 

Modified Bitumen

modified bitumen roof combines the technology of single-ply systems with the age-old reliability of BUR, because the felts used in modified bitumen are reinforced with plastic or rubber: 

  • atactic polypropylene (APP) 
  • styrene-butadiene-styrene (SBS) synthetic rubber

The rolls have the easy application of BUR, but the resilience and durability of single-ply membrane. Leading BUR manufacturers that Beldon Roofing works with in these flat roof materials include: 

  • GAF
  • Derbigum
  • Johns Manville
  • Soprema
  • US Ply
