A Comprehensive Guide to Commercial Roofing for Property Owners and Managers

Whether you’re a seasoned property manager or a building owner, having a solid understanding of commercial roofing is paramount. Commercial roofing systems play a crucial role in safeguarding properties, ensuring the safety of occupants, and preserving valuable assets. In this guide, we’ll explore three key areas:

  • Commercial Roofing Materials
  • Commercial Roofing Services
  • Commercial Roofing Manufacturers


Commercial Roofing Types

Commercial roofing encompasses various systems and materials, broadly categorized into low slope and steep slope roofs. Low slope roofs, with a pitch less than 3-in-12, are prevalent in diverse commercial settings. Steep slope roofs, featuring a pitch greater than 3-in-12, are commonly found in multifamily, condominium, and smaller commercial properties.

Low Slope
Commercial Roofing Materials

Low slope commercial roofing materials include TPO, EPDM, built-up roofing, modified bitumen, metal, and PVC. TPO roofing, known for its durability and affordability, has gained popularity since its introduction in 1991. EPDM roofing, often referred to as rubber roofing, is another reliable choice. Built-up roofing and modified bitumen offer superior waterproofing, while metal and PVC roofing cater to specific needs.

Steep Slope
Commercial Roofing Materials

Steep slope roofing, prevalent in multifamily, condominiums, and smaller commercial buildings, includes asphalt shingles, metal, tile, and slate. Asphalt shingles are the most common choice, while metal roofing is suitable for various applications. Tile roofing, primarily found in the southwest U.S., is known for its longevity, and slate roofing, though rare, is prized for its durability.

Commercial Roofing Manufacturers

Property managers should be somewhat familiar with leading commercial roofing manufacturers, particularly the ones that have their product on your roof. Notable manufacturers include Owens Corning, GAF, CertainTeed, Johns Manville, Firestone, Malarkey, Sika Sarnafil, Duro-Last, and Carlisle Syntec.
