Temperature Extremes Affect Your Home. Your Roof Can Help.

June 27, 2018

Metal Shingle

Typical construction methods attempt to deal with temperature extremes, both hot and cold, through insulation. The desire is to maintain comfortable temperatures inside the home as economically as possible. While insulation provides thermal mass to prevent heat migration in or out of your home, building science is showing us other, sometimes better, ways to do this as well.

Temperature Extremes and Roofing

When it comes to roofing, there are metal roofs and asphalt shingle roofs available that incorporate special high-tech reflective pigments. While these pigments will not offer the same reflectivity as a white roof, they will provide greater reflectivity than standard dark colors. 

Energy Efficiency

Ventilation is used to vent heat out of the attic, reducing air conditioning costs. Proper attic ventilation is a great way to exhaust summertime heat gain back to the outside before it reaches your home’s living space. Likewise, radiant barriers can be used to reflect away radiant heat. For a radiant barrier to be effective, it must face airspace and not be tightly sandwiched within a system of other materials. Tests have shown that good ventilation is effective at home energy efficiency.

Extreme Cold

In winter, temperature extremes create ice dams that can severely damage your home. Once again, proper attic ventilation is key to eliminating those interesting but harmful icicles from tearing at your gutters or roof’s edge. You might not think that ice dams form regularly on our roofs here in Georgia…and you would be right. However, those unexpected snows of the last few winters have done some damage!
