On a hot summer day, temperatures on a traditional dark surface rooftop can shoot up pretty high. This heat absorbed by the roof makes the temperature within the house rise, which subsequently leads to requirements of higher air conditioning, more energy costs, and of course, greater discomfort in the peak of summer. The solution to this problem, a cool roof, is surprisingly simple, low cost and quite easily applicable.
A cool roof essentially reflects a more significant amount of sunlight. It lets out more heat than a regular dark surface roof, helping maintain a relatively lower surface temperature in bright sunshine. At Allegiant Roofing Dayton OH and Allegiant Roofing Cincinnati OH, we help you make your roof heatproof, conserve energy and save money at the same time.
Here are some ways you can make your roof heatproof
Ballasted roof system
While these roofs are usually ballasted with gravel, the roof membrane is not anchored or adhered to the decking material. The stones help hold the roof membrane in place and, at the same time, form an insulating barrier against solar heat. This is also a relatively cheaper method.
A layer of green on your roof gives the same benefits as a ‘cool roof’ and helps reduce stormwater runoff. The process of evaporation and transpiration that plants create can reduce surface and surrounding air temperatures apart from providing natural shade from the heat.
The right Shingle
If regular fibreglass asphalt can be replaced with cool asphalt shingles containing specially coated reflective granules that help reflect a greater amount of sunlight. This is a very popular choice as even standard ones made from wood, polymer, and metal can easily be coated to better their reflective properties.
Evaporative/Roof mist cooling system
This is a low-tech and low-cost yet effective method to create a cool roof, and it does not require the addition of new roof materials. The surface temperature gets lowered by spraying small amounts of water across the roof, creating a cooling effect as it evaporates.
All you need to do is install a mist setting that is aimed across the roof. The system usually consumes less than a pint of water per square foot per day.
Choose the right tile
Depending on their colors and type, some tiles have naturally reflective properties, that is, the amount of clay content. Roofing Dayton OH and roofing Cincinnati OH usually use earth-toned colors, including brown, green, and terra cotta.
Cool roof coating
Coatings can either contain concrete/ceramic particles or polymers, which help improve the solar reflectance of the roof surface. They are applied with the help of sprayers, rollers or brushes and give the effect of a white brightly painted roof surface.
Metal roofs make for a better choice if you have steep roofs as they are naturally reflective but tend to hold heat. We at Allegiant Roofing Dayton OH and Allegiant Roofing Cincinnati OH also specialize in applying an excellent roof coating that can improve a metal roof’s heat-releasing properties, giving it a cool roof status.
