Visualizing Benefits of Roof Overhangs

If you’re in a sunny location and your home has windows, then you probably like to pull a curtain or close the shutters to keep direct heat from entering the home.  Just today I was driving by a modern home with slight overhangs and nodded my head in approval thinking: "buya … such a simple design element and it’s providing shading for those super large windows during the heat of the day."  I realize we’re talking about something basic, but if you have the chance, roof overhangs can make a difference as to how much you’re manipulating the interior temperature with mechanical systems.  Check this ranch house by Cottam Hargrave.  With that much glass in Georgetown, Texas, a little roof overhang is a prerequisite, don’t you think?!
