California is no stranger to hot summers, no matter where you live. Depending on your location, temperatures can reach 100 degrees Fahrenheit and can stay in the 90s for days on end. With these high temperatures, it can be a challenge to keep your building cool. Having a metal roof could be the solution to living comfortably in these heatwaves. Metal roofing is highly reflective, which means heat is reflected away from the building to keep it cooler, as opposed to other roofing materials that absorb the heat. The low thermal mass of metal allows it to reflect away heat so less heat is transferred to the inside of your building.
Why Metal Roofing Is The Best For Heat?
You can also add pigmentation to metal roofing to help emit up to 90% of the absorbed heat. For especially warm climates, you can take an extra step to keep the building cool. Choose a metal roofing system with inbuilt airspace between the underlayment and the metal panel. This insulation prevents heat transmission and the underlying material can absorb the heat instead of your building.
Keeping a Metal Roof Cool
Metal is known to react with heat, so how does it help keep your building cool?
- It reflects sunlight: Metal absorbs heat but is also reflective. Sunlight and heat can be reflected away. Even if the metal roof feels hot to touch, the heat will not be transferred to the building.
- It is energy-efficient: With heat being reflected away, less heat will enter your building. The air inside will be cooler which means you do not need to run the air conditioning units as often. A metal roof can save energy by up to 40%.
- It saves money: The more your air conditioner works, the more money you’ll spend. An air conditioner working overtime will also wear out more quickly and replacing or repairing it can be expensive. Metal roofing gives the air conditioner a break and saves you money.
The Best Kind of Metal Roof
There are different metals and paints that have reflective properties to help keep your building cool and save money. Take time to research the options and evaluate durability, strength, and cost. We have several options for metal and reflective roofing options and can help you find the right fit for your budget and building. Many manufacturers now have cool metal roof technology. With this, the solar reflectance is high and emittance is low. The surface quality is important as this determines how well the roof will cool. Lighter color roofing is also better at reflecting heat away. Roof color is more important than material, so be sure to consider both when choosing your next cool roof.
