Reflective Roof Coatings

When designing an energy efficient home, reflective roof coatings are an excellent option. They reduce the amount of heat absorbed and reduce the summer cooling costs. Sometimes called cool roofs, reflective roofing come in a wide variety of colors and styles to match any home. These types of roofs are great energy savers, can last longer than standard materials, and keep the home comfortable.

“Reflective roof coatings keep both temperatures and costs low.”

Basics Of Reflective Roof Coatings

Cool roofs works in two ways to keep the home comfortable. It reflects the sun’s rays, keeping the home cooler. It also uses thermal emittance, radiating heat back into the atmosphere to help dissipate that which is absorbed or produced by the home. This potent combination is great for the environment and your wallet.

Reflective Roof Coating and Energy Savings

The energy savings possible with a reflective roof coating are quite significant, but can vary according to several factors. Of course, the location and climate will have an impact. The hotter the region is, the more potential savings there are. A sunny lot with poor shade will find a larger change in cooling costs with reflective roof coatings. The shape of the home and other factors may have an effect also. The bottom line is, no matter what kind of reflective roof coating you use, it will improve the energy usage of the home.

Selecting Color

The color of reflective roof coatings is important. White coatings are the most effective and can reflect between 50% and 90% of sunlight. Another category, highly reflective, looks like aluminum roofs and usually reflects from 60% to 70% of the rays. If appearance is a more important consideration, there are plenty of darker colors available, but they generally reflect anywhere from 15% to 35%.

Metal

Metal roofs are made of aluminum, stainless steel, or other metals. These will prevent some heat from affecting the interior, but they do trap heat instead of reflecting. A reflective coating will increase energy efficiency.

Tiles

Tile roofs can be treated with a reflective coating to improve energy efficiency. The color of the tiles is important. Darker colors absorb heat, allowing the surface and inside of the home to heat quickly. A light color will reflect more of the sun’s rays. A light colored, treated tile will help to keep the interior of the home cool and reduce energy use.

Membranes

Roofing membranes, like tiles, need to have the right color to reflect heat. No matter the material, darker colors will absorb and retain more heat, so lighter choices are more energy efficient to cool. Darker membranes, like those designed to mimic slate shingles, will not reflect heat well. Cooling costs will be much higher than with a lighter colored membrane.

White Roof

White roofs are specifically engineered to be reflective. They will absorb less than any other roof type used today. Nearly any roof can be covered with a white reflective surface. A quality coating can lower air conditioning costs and prevent UV rays and other sun damage to the roofing materials.
