Flat Roofing

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 a flat roof to some portions of the home – like over porches, balconies, garages and sheds.

In the past, most flat roofs typically did not last as long as sloped roofs; however, within the last few decades, flat 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>

Flat Roofing Materials

There are three general types of flat roofing systems.

    BUILT-UP ROOFS

    • Manufactured using built-up layers of asphalt, rolled asphalt or modified bitumen
    • As the roof is installed, the different materials are added on to increase durability and longevity
    • 2 types of built-up roofs: Modified Bitumen and Rolled Asphalt
    • Requires at least 1/12-inch slope in order to be used

    Spray-On/Paint-on-Roofs

    • Spray Foam Insulation: Foam is sprayed directly onto the roof deck with acrylic or urethane coating as well as a layer of crushed stones/sand
    • Roof Coatings: Ideal for existing roofs and used to extend their service life by 10 to 15 years and typically installed on top of singly-ply, modified or low-slope metal roofs.
