Flat Roofing

flat roof

Are you considering installing a flat roof on your home or business? Flat or low-slope roofs look very attractive on many different types of buildings. Many traditional-style homes only add this style some portions of the home – like over porches, balconies, garages and sheds.

In the past, most flat-style roofs typically did not last as long as sloped roofs; however, within the last few decades, flat-style roofing manufacturers have been developing membranes that are highly durable and energy-efficient, and that can even match the longevity of sloped roofs.

Benefits of Flat Roofing Systems

  • Great for large buildings
  • Can have multiple uses, such as a deck, rooftop garden, patio or penthouse
  • Huge savings on energy bills since TPO and PVC are able to reflect about 90% of solar rays
  • TPO and PVC are 100% recyclable
  • Installation costs are lower since you don’t have to tear off the old roof before installation>
