Flat roofing is one of the most popular and efficient roofing options available, but they have one major drawback. Flat roofing is more prone to trapping heat than other roofing systems and this causes your building to be warmer and your energy costs higher. Manufacturers, however, have developed a number of solutions you can use to keep your flat roof cool all year round.

How To Keep Your Flat Roof Cool?

Roof Coating

Specialized roof coatings have been developed that will reduce heat absorption. Any of the materials below will help reflect up to 90 percent of the sun’s heat and light away so you can save on energy.

  • PVC sheathing: PVC sheathing is great for structurally-sound buildings. When applied to the entire surface, the heat-welded seams will keep water out while the smooth surface prevents wind damage. PVC sheathing is reliable for close to 15 years and can effectively withstand all weather conditions.
  • Elastomeric paint: The elastomeric polymer in this paint expands and contracts along with the material is applied to. When the bright white version is used, you will increase reflectivity and reduce heat absorption, so your building stays cooler and you can save on energy consumption.
  • Asbestos film: Low-sloping asbestos film shields can be erected over your roof to help increase reflectivity. These shields prevent heat absorption s your roof and building stay cooler. Just be sure to erect the shield so it does not catch prevailing winds and blow away.
  • Solar Photovoltaic panels: These thin panels are ideal for reflecting away the sun’s light and heat and they also store energy for future use. When used along with a PVC laminate roofing system, you can get the most efficient energy consumption for your building.

Other Cooling Options

  • Foam insulation: If you get a chance to replace your ceiling, then you should consider installing a layer of foam insulation under your roofing is ideal. This effectively regulates heat absorption and temperature, keeping your building warm or cool depending on the season.
  • Windcatchers: Windcatchers helps to direct cool air downwards. Their dome-shape and vertical weather vanes rotate with even the smallest breeze, forcing cool air down to the vents of the building. No need to worry about the weather when it turns cold, because there is a vent seal to keep cold air out.


Each of the solutions discussed above can effectively help you to reduce energy use and keep your building cool. Reducing heat absorption and keeping energy use to a minimum saves you money and keeps your roofing system in better condition for longer. We will work with you to get the right cooling option in place for you, so you can run your building more efficiently tomorrow.
