What is a key difference between residential and commercial roofing?

The distinction between residential and commercial roofing primarily lies in the type of roofing systems and materials used. Residential roofing typically involves steep-sloped designs that are commonly finished with shingles, which can be asphalt, wood, or other materials designed for aesthetic appeal and residential needs.

On the other hand, commercial roofing frequently utilizes flat or low-slope roofs and membrane systems such as TPO (thermoplastic polyolefin), PVC (polyvinyl chloride), or EPDM (ethylene propylene diene monomer). These materials are selected for their durability and effectiveness in managing larger structures’ water drainage and weatherproofing needs.

The residential and commercial applications also reflect different considerations in terms of structural requirements, fire codes, and installation methods, further emphasizing the diversity in roofing approaches for different environments. Understanding this key difference is essential for roofing professionals when determining the appropriate materials and systems for their projects.
