It’s a hot summer day in Ohio, you walk outside onto black asphalt barefoot and quickly realize its so hot that you will burn your feet.
Imagine you walk out onto your black roof barefoot, now imagine if that same roof was white?
The sun heats up black or dark colored membrane roofs, and the heat can’t escape, which warms up your building.
The Cool Roofs Rating Council does just that, it rates roof membranes on their SRI, Solar Reflectance Index. That is, a measure of the constructed surface’s ability to stay cool in the sun by reflecting solar radiation and emitting thermal radiation. The SRI of a black rubber roof is around 1 whereas the SRI of a white PVC roof is more like 111. The higher the number the better.
DCA Roofing can combat these “hot roofs” by installing a single-ply cool roof that is Energy Star rated. Often, we are able to install this roofing over top the current roof system.
