How To Make Roof Absurb Less Heat

Still the shine of bright white on a roof is imposing and can take away from the overall aesthetic of the house.

How to make roof absurb less heat.

Traditionally the asphalt and surface gravel in a built up roof have been black or dark gray trapping much more light and heat than they release but there are several ways to make a built up roof cool. One is to replace the surface layer with white gravel or reflective marble chips to increase its solar reflectance. Awell insulated house will gain only 1 f 0 6 c per hour if the outside temperature is 85 to 90 f 29 to 32 c. White is the most reflective color and white metal roofing can actually lower the ambient temperature in the home by reflecting more of the sun s rays into the environment.

Even the dark metal colors retain less heat than the relatively light shingles. Cool roofs can be made of a highly reflective type of paint a sheet covering or highly reflective tiles or shingles. The best way to beat the heat is to not absorb it in the first place. I can tell you that my experience is that any metal roof is cooler than asphalt shingles.

Some roofing materials come in cool roof options and others can be altered with a highly reflective type of paint or coating to absorb less heat. Use light color metal roof with overhangs to shade the walls on the south and west sides. As a result your air conditioner operates more efficiently uses less energy and leads to lower utility bills. If you have a light roof your home absorbs less heat through the roof during summertime.

In most cases a cool roof will stay at least 50 f cooler than a non cool roof of the same color and construction. By the time the interior heats up the outside air should be cooler and can be allowed indoors.
