According to the National Oceanic Atmospheric Administration (NOAA), the weather from June to August this year will be hotter than normal. NOAA forecasts that the temperatures of the US southwest region will rise by one or two degrees above average.
All Star Improvements owner, Alex Simpson who has three decades of experience in the roofing industry provides tips to homeowners on how roofs can help them save costs.
The stress on air conditioning can be relieved through proper roof ventilation, which ensures movement of fresh air via the attic. In addition, soffits or vents can be fitted on the roof to drive out the hot air from attic or roof. A vented attic reduces the temperature and cooling expenses. In addition, checking for blockage in vents caused by insulation in the attic will result in a cooler attic
A sprayed polyurethane foam (SPF) roof system is now becoming a feasible option for reducing energy costs. In order to insulate the roof from the effects of infrared rays, a seamless, thermal blanket is formed by spraying polyurethane foam onto the roof. This way, the roof is prevented from getting heated up and the heat is not transmitted into the building. This kind of insulation saves around 30%-70% of energy.
According to Alex, a cool roof is also a reflective roof, which reflects heat rather than absorbing it. Black roofs or other dark colored roofs tend to have low-reflectance surfaces, which result in extreme temperature of 150°F to 190°F under hot weather conditions, increase utilization of cooling energy, and raise energy bills. On the other hand, light-colored “cool roofs” have high reflectance surfaces, which result in up to 70°C cooler temperature during hot weather conditions when compared to conventional materials.
Alex also informed that innovations and improvements are regularly being made in roof systems. Homeowners can contact professionals to understand the benefits of the roof system.
