Normal roof overhang length.

You will need to express this size in terms of square feet. Metal is usually installed on rafters or strip sheathing rather than the solid decking used under other materials. Rafter span tables use these tables to determine lengths sizes and spacing of rafters based on a variety of factors such as species load grade spacing and pitch. Roof pitches in.

This is particularly true in geographical regions where high winds are a common issue. Measure your house at ground level then add in the roof s overhang for greater accuracy. Visit the roof framing page for more information on cutting roof rafters and visit the roof pitch calculator for determining rafter lengths based on rise and run.
