As efficient as flat roofing can be, they have one major drawback. Flat roofing is more prone to trapping heat, which makes your building warmer than you would like and your energy costs high. Thankfully, there are a number of solutions you can use to keep your flat roof cool and energy use low.
6 Ways To Cool a Flat Roof
Roof Coating Options
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.
- Elastomeric paint: The elastomeric polymer in this paint allows it to expand and contract with the material is applied to. Two coats of this bright white paint will increase reflectivity and reduce heat absorption, so your building stays cooler and you can save on energy consumption.
- PVC sheathing: PVC sheathing is great for structurally-sound buildings. It is applied to the entire surface and the heat-welded seams keep water out while the smooth surface prevents wind damage. The best sheathing lasts for close to 15 years and can effectively withstand all weather conditions.
- Asbestos film: Low-sloping asbestos film shields can be erected over your roof to help increase reflectivity, so your flat roof does not absorb too much heat. Just be sure to erect the shield so it does not catch prevailing winds and blow away.
- Solar Photovoltaic panels: These super thin panels are ideal for reflecting away the sun’s light and heat and they can store energy for you to use for you to use. When placed over a PVC laminate roofing system, you can get the most efficient energy consumption for your building.
Other Cooling Options
- Windcatchers: Windcatchers helps to direct cool air downwards. The dome-shaped windcatcher with its vertical weather vanes rotates with even the smallest breeze, forcing cool air down to the vents of the building. When the weather is too cold, there is a vent seal to keep cold air out.
- Foam insulation: Should you get the chance to replace your ceiling. Installing a layer of foam insulation under your roofing is ideal. This effectively regulated hot and cold, keeping your building warm during cool months and cool during the summer.
