The ideal shed roof overhang depends on the purpose of the overhang the location and microclimate of the building.

How much should a shed roof overhang.

Roof overhangs can extend farther than 2 feet but beyond this length they begin to lose structural integrity and require external supports. An overhang to protect the shed user on a rainy night could be relatively small whereas an overhang to provide a shaded area in front of the shed to keep the interior of the shed cool will be much larger. A shed overhang is an easy and effective way to protect your shed.

Some slight overhang is recommended in conjunction with a drip edge flashing to prevent water from getting under the roofing and onto underlying wood. Overhangs can vary from a few inches to a few feet depending on preference.
