Standard Roof Overhang Length

That said overhangs can extend as far as 2 without the need for external supports.

Standard roof overhang length.

The ideal spec for roof overhangs the size of the roof overhang depends on the property. Two feet is the general maximum length for a typical roof overhang. But roof overhangs are a great system to protect houses 3 stories and under. On very tall buildings there are hardly any benefits of roof overhangs as the surface areas of the walls are so high.

This can make extensive roof overhangs more trouble than they are worth in all but the harshest climates. A standard overhang is 16 24 inches but the overhang can be any length you wish. 12 to 16 foot eaves 18 inch overhangs. However the suggested width of an overhang is between 12 and 18 for eaves and no more than 8 for rakes.

This will keep rain away from your shed. For example a slope of 6 12 means for every 12 inches of horizontal distance the slope of the roof will rise 6 inches vertically. 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.

A typical metal roof overhang may be 2 to 4 inches or even less. Pitch slope the pitch or slope is the incline of the roof expressed as a fraction describing the rise over the run. 16 foot and taller 24 inch overhangs. The rise will be the elevation change over the 12 inches.

The run or the base number is 12 inches. We can also build a cantilever for the overhang which is where the bottom chord of the truss continues beyond the wall. The exceptions include enclosed overhangs on open sidewalls i do not like the look and they become a nesting place for small flying critters and birds. You can add 3 to 5 inches to the top.

This will protect a roof from most types of damage.
