Standard Roof Overhang

Metal is usually installed on rafters or strip sheathing rather than the solid decking used under other materials.

Standard roof overhang.

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. The overhang at the bottom of the slope is a simple overhang. 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. 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.

Roof overhangs are the amount that the roof hangs over the top of the siding in residential home construction. The roof overhang refers to how much the edge of the roof goes beyond the house siding. A standard overhang is 16 24 inches but the overhang can be any length you wish. The siding underneath the overhang is known as the soffit.

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. In general roof overhangs offer an effective solution for how to protect windows doors and entryways. The length of the overhang depends primarily on the climate.

Overhangs are common in most house designs providing protection against both wind and rain. Under the overhang is a structure known as the soffit. With a flat shed roof the roof simply extends past the wall plate to provide an overhang. A typical metal roof overhang may be 2 to 4 inches or even less.

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. The roof overhang occurs in a similar way to the pent roof in that the top chord of the roof truss projects past the wall plate by the desired amount. The size of the roof overhang you choose depends largely on the style of your shed s roof.
