Standard Roof Overhang

Under the overhang is a structure known as the soffit.

Standard roof overhang.

The length of the overhang depends primarily on the climate. Whereas the overhang on the gable end is a gable ladder. A typical metal roof overhang may be 2 to 4 inches or even less. Metal is usually installed on rafters or strip sheathing rather than the solid decking used under other materials.

If the overhang exceeds 2 5 feet we will need to use a larger top chord for the overhang typically a 2 6 top chord for the truss. Some slight overhang is recommended in conjunction with a drip edge flashing to prevent water from getting under the roofing and onto underlying wood. The siding underneath the overhang is known as the soffit. The size of the roof overhang you choose depends largely on the style of your shed s roof.

Roof overhangs are the amount that the roof hangs over the top of the siding in residential home construction. At the rakes however with a nod to yankee frugality and clean modern lines we kept the roof trim as close to flush as practical while still allowing for a rain screen channel. With that in mind we kept a roof overhang at the eaves as it provides a nice shadow line and protects the second floor windows from a bit of the summer sun. If the roof overhang is not big enough then the only way to protect these windows doors and entryways is by recessing them into the thick exterior wall or by installing special casing and flashing for each door or entryway.

With a flat shed roof the roof simply extends past the wall plate to provide an overhang. A standard overhang is 16 24 inches but the overhang can be any length you wish. Most homes have an overhang however length varies greatly depending on the architectural style of the roof with slate roofs having longer overhangs typically. We can also build a cantilever for the overhang which is where the bottom chord of the truss continues beyond the wall.

The overhang at the bottom of the slope is a simple overhang. In general roof overhangs offer an effective solution for how to protect windows doors and entryways. Because this style of a shed has a flat roof it can facilitate a wider overhang which is ideal for storage.
