Bade Roofing Offers Tips on How a Common Roofing Process Can Keep Your Building Up to 50 Degrees Cooler
As we experience the dog days of summer, building owners and managers are likely considering ways to keep their cooling costs down. This can be a particularly
critical issue for anyone planning to construct a new building or planning to replace or restore an existing roof. That’s where a cool roof comes in.
A cool roof is a process by which many common roofing surfaces are made “cool” by applying coatings, which are either white or contain special reflective
pigments that reflect sunlight. Cool roofs protect the roof surface from ultra-violet (UV) rays and chemical damage that can cause premature aging
and drying. Additionally, cool roofs absorb less heat and keep the entire building cooler and at a more consistent temperature, thereby reducing energy
usage and the corresponding expense.
According to St. Louis-based Bade Roofing Company, a standard or dark roof can reach temperatures of up to 150 degrees, but a cool roof, under the same
conditions, could be more than 50 degrees cooler.

“Cool roofs help keep extra heat out of a building during the summer without losing heat during the winter. This means lower energy costs as you don’t need as much air conditioning. They’re also better for the environment,” said Dave Bade, CEO of Bade Roofing Company.
Below, Bade Roofing shares some examples of common roofing types and how they can be made cool:
Built-up Roofs: Built-up roofs are the old standard tar-and-gravel combination that is typically black or dark gray. To make this roof cool, you
can replace the surface layer with a UV-resistant white mineral fiberglass surface or coating.
Roof Coatings: Roof coatingsare constructed by mixing two liquid chemicals together that react and expand to form one solid piece that adheres to
the roof. A reflective, protective coating can be applied to this type of roof that offers cool-roof performance.
Metal Roofs: Metal roofs can be made cool simply by painting the surface with a reflective paint or coating.
Modified Bitumen: Modified bitumen contains one or more layers of a plastic or rubber material with reinforcing materials and topped with a surfacing
material. This roof type can be made cool by adding a cool-roof coating to achieve a high solar reflectance.
Shingles, Slate, or Tile: These roofing products are used for steeper-sloped commercial buildings. For cool asphalt shingles, you’ll need to use
specially coated granules that provide better solar reflectance. Slate and tile products are available with solar-reflective surfaces in a variety
Single-ply: Single-ply roofing is a pre-fabricated sheet that is rolled onto the roof in a single layer and attached with mechanical fasteners,
adhered with chemical adhesives, or held in place with gravel, stones or pavers. To make this roof type cool, single-ply roofing products can be ordered
with ultra-violet-resistant and highly reflective surfaces.
