Standard roof overhang northern michigan.

Overhangs are common in most house designs providing protection against both wind and rain. In order to stay intact and in place a roof must be able to resist loads both permanent and temporary that are pushing. The length of the overhang depends primarily on the climate. The state has amended the snow load requirements of the 2009 ibc figure 1608 2 and the 2009 irc figure r301 2 5 table r301 2 1 and table.

Eave overhangs shall not exceed 24 inches 610 mm measured horizontally. Although there is no single standard roof pitch used on all sloped roofs factors such as roofing materials and local climate help to determine the appropriate range of pitches for a given building. The siding underneath the overhang is known as the soffit. They can also include certain architectural features that make overhangs more than just functional parts of the home.
