There are several ways to block and remove heat, including shading through landscaping, using a dark exterior paint, installing a radiant barrier in the roof rafters and good old- fashioned insulation. Another way is through thermal siphoning, the process of removing heat through controlled airflow...
This is partially because a roof with a steep pitch needs more lumber to cover the same distance as a roof with a gradual pitch. For example, if two roofs measure 2,000 square feet, but one has a pitch of 4/12 and the other has a pitch of 9/12, the cost to frame the 9/12 ...
