Standard Length Of A Roof Overhang

The size of the roof overhang you choose depends largely on the style of your shed s roof.

Standard length of a roof overhang.

If the home only has one level the standard roof design strategy is clear. The roof overhang length must be properly engineered to resist wind uplift. This is particularly true in geographical regions where high winds are a common issue. Again this length can be adjusted to fit the need of the truss.

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 length of the overhang depends primarily on the climate. For example 4 12. A typical metal roof overhang may be 2 to 4 inches or even less.

The roof overhang refers to how much the edge of the roof goes beyond the house siding. If the overhang extends beyond 24 inches say to 30 inches then a 2 6 top chord for the tail section will be required to handle the additional overhang. Make the main roof wide enough to protect all windows and doors. Overhangs are common in most house designs providing protection against both wind and rain.

By precutting all of the roof purlins to length and making any necessary adjustments in the last bay of the roof it should be possible to easily be within 1 16 th inch plus or minus. The diagonal measures are actually relatively easy to get equal as it takes very little effort to shrink a long diagonal by several inches. The siding underneath the overhang is known as the soffit. Metal is usually installed on rafters or strip sheathing rather than the solid decking used under other materials.

Because this style of a shed has a flat roof it can facilitate a wider overhang which is ideal for storage. 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. Most homes have an overhang however length varies greatly depending on the architectural style of the roof with slate roofs having longer overhangs typically.

Roof overhangs are the amount that the roof hangs over the top of the siding in residential home construction. Some slight overhang is recommended in conjunction with a drip edge flashing to prevent water from getting under the roofing and onto underlying wood.
