What You Need to Consider When Choosing a Cool Roof

Cool roofing, as an industry practice, is not new. Back in the old days, it was as simple as painting your roof a lighter color. And to this day, this is what most people consider to be a cool roof is. This is also what we often get asked about when we perform roof repair services for some of our clients.

While that isn’t wrong per se, cool roofing is more than just the color of the roof. This is why we think that it is important for people to be aware of just what cool roofs are, and how they generally work. Rainier Roofing explains what you need to know about cool roofs in this post.

Reflection and Absorption

The old roofers weren’t entirely wrong. Reflecting the heat back and away from the home is part of what makes a cool roof live up to its name. But if the roof reflects some of the heat, and absorbs the rest, then it becomes an exercise in futility. That’s because the heat that the roof absorbs gets transferred back to the home.

This is why a lot of effort has gone towards making roofs that don’t just reflect the heat away–these new cool roofs also don’t absorb the excess heat. What does this mean? Basically, if your residential and commercial roofing service installs a cool roof on your property today, you will most likely be getting a roof that both absorbs and reflects radiant energy.

Do I Need a Cool Roof?

Not everybody needs a cool roof. These roofs are designed for areas that actually experience more heat than others, so if your location is generally cooler than other regions, there’s a good chance you won’t be needing a cool roof.

This is because getting a cool roof will actually make your heating bills go up. By adding that bit of radiant protection overhead, you’re missing out on letting the sun heat up your property naturally, which means the roof will actually make the building colder.

How Long Will Cool Roofs Last?

Generally, cool roof estimates show them lasting far longer than regular darker roofs. This is mostly because heat makes materials expand and contract in intervals, which is never good for your roof. So if you have a roofing material that absorbs and retains heat, then it will expand and contract continuously, leading to compromised material integrity.
