There are plenty of benefits to using cool roof technology. Cool roofs involve methods like having heat-reflective paint, shingles, tiles, or a sheet covering. Cool roofs can achieve substantial cooling savings. They’re a great way to improve indoor comfort and air temperature. Cool roofing can also help to protect your roof from the damaging radiation of the sun, which in turn can extend its service life. With a lower need for cooling energy, blackouts and brownouts are less likely, and power plants can reduce their emissions.
However, in warm, moist locations, cool roofs can be susceptible to mold or algae growth more than typical hot roofs. In some cases, materials will include special chemicals that prevent this for a few years. In colder temperatures, cool roofs can accumulate moisture through condensation, but this can be avoided using proper design techniques. Cool roofs may not be as cost-effective to install on an existing roof. In any case, be sure to consult a professional before making any decisions about your roof.
