How to Choose a Commercial Cool Roof

Cool roofs cut down on energy costs and help avoid the need for rolling blackouts in urban areas during months with extremely high temperatures.

There are various choices in cool roof materials, however, so how to choose a commercial cool roof may seem daunting. You want to focus on the “coolness” each roof system provides, which is typically labeled by its Solar Reflectance Index (SRI). A minimum SRI of 65 is recommended for a low sloop roof. It’s a calculation of solar reflectance and thermal emittance values.  This downloadable spreadsheet can calculate SRI.

You have three options: to coat the roof, recover the roof with a new waterproofing surface, or tear off the existing roof and replace it. Talk with a roofing contractor or consultant to determine which option makes sense for your building.

Why Your Flat Roof Should Be Fully Adhered (Instead of Ballasted)

Flat roofs are commonly protected with single-ply membrane systems that are great for years of leak-proof protection. These single-ply roof membranes for flat roofs are seamless and resistant to water, hail, snow, and wind. Sometimes, though, these commercial roof systems are installed using ballast to weigh them down instead of fully adhering the membrane to the roof substrate.

Let’s first look into what it means to have a ballasted roof and then we’ll explain why it’s not the best choice for commercial roof protection.

Common Issues with Flat Roofs [And How to Solve Them]

Many commercial and industrial buildings have flat roofs because they are less expensive to install and maintain than pitched roofs. Flat roofs, or “low slope” roofs, typically have a slope of 25% or less.

Water pooling, leaks, and membrane punctures are common issues with flat roofs. Protective coatings can remediate many of these issues.

Select the Best Coating for Flat Roof Repair

Although many buildings are said to have flat roofs, that is somewhat of a misnomer. Flat roofs are slightly sloped so that rain, snow, and other moisture can properly drain. So, even though they appear to be completely flat, they are not. However, their mostly flat structure allows for more efficient use of space and they are easier to install. Typically, the cost to maintain them is less expensive than the cost to maintain a pitched roof.

If your building endures dramatic climate changes throughout each season, its roofing material will be put under more stress than commercial buildings in more temperate, even climates. Temperature extreme can reduce the lifespan of a commercial roof. A roof that is accessed a lot will also wear down faster.
