How Can Different types of Roofs be made Cool?

A cool roof is characterized by its feature of absorbing less heat as compared to a traditional roof. You can convert your existing roof to a cool roof with the help of a reflective paint, a covering sheet, reflective shingles and tiles. Different products are available for converting various types of roofing systems. With its various benefits - cost savings being a major one - cool roofs are increasingly becoming popular. Here’s how common roofing systems can be converted to cool roofs.

Modified Bitumen

These types of roofs have one or more layers of rubber or plastic material and are surfaced with mineral granules for a smooth finish. These materials are held together with rolled reinforcing fabric and are fastened to the roof deck with adhesive or hot asphalt. Usually modified bitumen roofs are Gray or black; thus they absorb heat, rather than reflecting sunlight. This type of roof can be made cool with the help of a white coating. This will raise the solar reflectance according to the cool roof standards. The price of a cool modified bitumen as is same as the traditional modified bitumen.

 

Asphalt Shingle Roofs

These roofs are available in a variety of materials such as wood, polymers, fibreglass, and metals with overlapping panels. The available of variety and durability makes it a popular roofing choice, especially for residential purposes. These roofs can be made cool by replacing the standard asphalt shingles with cool asphalt shingles. They contain a special coating of reflective granules which help in reflecting better. Other types of shingles such as wood, metal etc. can also be coated to improve their reflectance.  

 

Tile Roofs

Clay, slate or concrete tiles, almost all types of tiles are used in roofing. They can be customized by coating with any colour of your choice. Depending on the type of clay and colour, some tiles have natural cooling properties. While the remaining types of tiles can be made cool through surface treatments which transform low solar reflective tiles to cool tiles.

 

Metal Roofs

Metal roofs are available with metallic finishes, granular coated surfaces or oven-baked paint finishes. It possesses high solar reflective but poor thermal emission properties, thus fail to qualify as a cool roof. They can be converted by applying a cool reflective coating. Painting a metal roof will improve the thermal emission quality of the roof and allow it to qualify as a cool roof.
