Ever notice the metal vents on the underside of your sofitt. These are soffit vents and they are meant to create air circulation in your attic. This circulation is aided by attic fans, both solar and wind driven, to keep you attic and your entire house cooler. Often times when insulation is installed or added to the attic the sofitt vents are covered and the air circulation is hampered. If this happens, simply have the insulation removed so that the air can circulate again. Also, make sure your home has enough sofitt vents for the size of your attic to create air flow. You will be amazed how your cooling bill with be reduced by doing simple maintance such as this. We recently helped a home in Plano with their sofitt vents.
