How to Keep Your Commercial Roof Cool During the Summer


Commercial building with a metal roof.

Understanding how to keep your commercial roof cool during the summer is the first step toward extending its life expectancy. Commercial roofs are subject to significant temperature fluctuation that can have a negative impact on their structural integrity.

Heat damage, for example, can dry out the necessary protective oils. When this occurs, roofs can become brittle, crack, and allow water to infiltrate the substrate. Hot roofs also cause HVAC systems to work harder and unnecessarily waste energy. The team at Davidoff Roofing hopes these tips on how to reduce roof heating help you extend its life.

1. Apply Reflective Roof Coatings

Reflective coatings have emerged as a go-to solution. They reroute the harmful UV rays that would otherwise be absorbed by your commercial roof. As long as your roof has a metal or rubber compound exterior, a roofing contractor can usually install a suitable reflective coating.

2. Add Roof Insulation

Spray foam insulation has a proven track record of reducing internal temperatures. Highly rated products prevent the warming rays of the sun to increase indoor temperatures, triggering air conditioning units. While additional insulation may not protect rubber roofs from drying out, it tends to be a practical solution for metal roofs, among others.

3. Install Solar Panels

Installing solar panels on a commercial roof can be a substantial win for property owners. The panels block the sun’s rays from overheating the roof. While helping to maintain stable internal temperatures, property owners enjoy the benefit of lowering their utility expenses. This win-win situation is even more gratifying knowing solar panel installations are a sustainable practice that protects the environment.

4. Implement Roof Ventilation Systems

Installing or upgrading a roof ventilation system has wide-reaching benefits. They provide added protection from water damage because ventilation systems reduce condensation between the insulation and roofing materials. Vents help expunge the warm air inside the building that forces the HVAC system to kick on. Free-flowing ventilation also improves the breathable air inhaled by you and your employees.

5. Conduct Regular Roof Maintenance

Routine maintenance and cleaning are key factors in how to keep your commercial roof cool during the summer. Addressing any dents, tears, or cavities the roof suffered during the harsh winter can prevent more costly repairs after they expand from heat. A seasonal roof cleaning also eliminates loose debris that can clog water drainage systems that might otherwise cause ponding. By scheduling seasonal maintenance, a roofing professional can identify problem areas and cure them before you incur more costly roof damage.
