Minimum roof overhang shed.

A shed overhang is an easy and effective way to protect your shed. Metal is usually installed on rafters or strip sheathing rather than the solid decking used under other materials. This will protect a roof from most types of damage. At the bottom of the shed wall the fact that water from the roof is being directed away from the shed means that the base of the shed gets less persistently damp.

Overhangs can vary in width from a few inches to several feet. The minimum pitch for a roof is 1 4 12 which translates to 1 4 inch rise to 12 inches of run. If you are building a shed roof with an overhang you will need to incorporate this into your shed roof plan and allow for the overhang as you build. A roof overhang can allow for the incorporation of soffits another roof ventilation option and they can help cover entryways and move rain water farther away from the shed and foundation.

With a large front overhang the shed can incorporate a nice outdoor seating area with patio. You can add 3 to 5 inches to the top. Remember metal roofing is more expensive than shingles. On sheds and homes overhangs are commonly referred to as eaves or rakes depending on where they are located.

A typical metal roof overhang may be 2 to 4 inches or even less. However you can only use this pitch with built up roofing or specialized synthetic roofing. Even a relatively small overhang can provide significant protection. An overhang is the portion of the roof that runs past the wall providing coverage for the space around the foundation of your shed.

When added to the use of a gutter to collect roof water the damage to the shed walls is minimised. Some slight overhang is recommended in conjunction with a drip edge flashing to prevent water from getting under the roofing and onto underlying wood. Roof overhangs can extend farther than 2 feet but beyond this length they begin to lose structural integrity and require external supports.
