Frequently Asked Questions

Commercial roofing is the installation and maintenance of commercial roofs. Facilities that can fall under “commercial”, include roofs for businesses, warehouses, or any other large structures.
Commercial roofing:
  • Installation and maintenance of roofs for large facilities or structures such as businesses or warehouses.
  • Roofing is built according to the specific needs of the individual business or facility.
  • Typically a flat roof style.
  • Based on the size and scale, commercial roofing is usually more expensive than residential roofing services.
Residential roofing:
  • Typically relates to roofing services for a customer’s personal residential home.
  • Roofing is built to protect the home from the weather and harsh elements.
  • Typically a pitched roof style.
  • Usually less expensive than commercial roofing.
When making a large commitment and choosing a roofing contractor, there are a few main factors you want to consider.
  • Do the workers have a license and insurance?
  • Do they have extensive experience?
  • When you look at the roofing business online do they have good reviews and references?
  • Do they offer free quotes or estimates?
  • Do they provide a warranty?

It’s difficult to say what the “best” commercial roofing material is because each commercial building should have a roof that fits its particular needs. However, some of the most common roofing materials used for commercial roofing include metal, BUR membrane, green roofing, silicon, thermoset, shingles, thermoplastic polyolefin (TPO), and poly vinyl chloride (PVC).

You will usually see a flat roof style on commercial buildings. This is because, for the size and scale of commercial buildings, this sort of style is more cost-effective and quicker to install compared to the pitched roofs you may see for residential housing. When a commercial building has a flat roofing style it also allows for the placement and storage of HVAC units, solar panels, or other equipment.

This is a figure that depends on the commercial building in question. Depending on the facility, its size, and functionality, the lifespan of a commercial roof can vary significantly. To maximize the lifespan of your commercial roof, you want to make sure it’s installed properly by the right professionals.
