Cool Roofs

Cool roofs reflect sunlight and heat instead of absorb the heat as with more traditional roofing materials. By not absorbing the heat, which then transfers that heat to the home, they cut down significantly on energy costs and keep homes cooler in the hot summer months. Discover more about this environmentally sound and cost effective roofing alternative.

Basics Of Cool Roofs

Cool roofs is the generic name given to any roofing material that reflects sunlight and reradiates the heat from UV rays back into the air. This solar reflectivity accomplishes several positive goals. Since the roof does not absorb the heat, the home or building below does not get as hot – reducing the need for as much cooling in the summer. Top of the line cool roofs can lower air conditioning cost by as much as 20%. This will not pay for the entire roof replacement cost but can certainly defray some of the initial outlay of cash. In addition, cool roofs are much easier on roof air conditioning units because the surface temperature is so much lower. Finally, cool roofs have good longevity because they do not take as much wear and tear from powerful UV rays that cause damage over time to roof surfaces.

Cool Roof Rating Council

The CRRC or Cool Roof Rating Council is a non-profit group that measures or rates different materials on their radioactive heating effects on surfaces. Homeowners can check with the CRRC to see how effective their current roofing surfaces do when it comes to surface heat. For homeowners considering replacing their roof, they can get good unbiased information on the efficiency of the products and materials they are considering.

Advantages

Energy Savings
Because cool roofs reflects heat back into the environment, they maintain a lower surface temperature which does not transfer heat into the home and therefore lowers the amount of A/C that must be used in the hot summer months.

Less Urban Heat Island
Urban heat island effect refers to the fact that urban areas are often hotter than more rural areas (by as much as 10 degrees!) because of heat absorbing materials in such close proximity to one another. This can add to the huge strains on energy consumption systems in hot months that often results in rolling blackouts as a way to not overload the energy grids. Cool roofs help to temper this effect, which can also add to smog and pollution levels.

Recycled Materials
Many manufacturers have begun to use recycled or non toxic materials into their products. Some metal synthetic materials such as a synthetic slate roof use recycled content which means less new resources are needed in their production. Less resources means lower costs (in many instances).

Less Maintenance
Cool roofs often have a longer life span than traditional materials. This is due mainly to less UV damage and moisture being trapped beneath shingles etc. Cool roofs therefore are less prone to cracking and splitting at seams, which is one of the ways that roofs fail.
