A Commercial Flat Roof Saves You Money, But Requires A Lot of Maintenance

Flat roofs are the most popular roofing system for commercial buildings. They are affordable, versatile, and practical which appeals to business owners. Their flat design is also needed for tall skyscrapers whose pointed roofs would be a safety hazard from too much weight that high up. They are prone to getting damaged more easily than residential roofs, but commercial flat roofs have tons of foot traffic and air conditioning units on top of them compared to one single home. It’s important to weigh the advantages and disadvantages of flat roofing when deciding to get a commercial roof for your building.

Pros and Cons of Installing a Flat Roof


  • Flat roof are cheaper than sloped roofs because this is less materials to install and quicker installation time.
  • Provides great storage space or can be used as a rooftop patio or deck
  • Many flat roofs are cool roofs, meaning they reflect sunlight and UV rays, which cool the building. This lowers the temperatures inside and helps lower energy bills, as well.


  • Flat roofs don’t have sloped gables, so they are prone to leaks and holes as rainwater pools on the roof and can’t drain anywhere.
  • Commercial building owners often have to call for flat roof repair because of storm damage or damage from their rooftop HVAC unit to their flat roofing. With Carrier HVAC systems, this can help to eliminate one future cause of flat roof damages.
  • Flat roofs have direct access to sunlight, whereas sloped roofs would have some protection. This causes flat roofs to age faster because of the harsh UV rays.
  • Commercial flat roofs don’t have very long lifespans, especially built up roofs and industrial roofs. If metal or if the flat roof had a roof coating applied over it, this helps to extend its lift by a minimum of 10 years.
