Standard Roof Overhang Length

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.

Standard roof overhang length.

We can also build a cantilever for the overhang which is where the bottom chord of the truss continues beyond the wall. Roof overhangs can extend farther than 2 feet but beyond this length they begin to lose structural integrity and require external supports. The run or the base number is 12 inches. The rise will be the elevation change over the 12 inches.

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. 16 foot and taller 24 inch overhangs. A typical metal roof overhang may be 2 to 4 inches or even less. You can add 3 to 5 inches to the top.

12 to 16 foot eaves 18 inch overhangs. Overhangs can vary from a few inches to a few feet depending on preference. On very tall buildings there are hardly any benefits of roof overhangs as the surface areas of the walls are so high. The ideal spec for roof overhangs the size of the roof overhang depends on the property.

Some slight overhang is recommended in conjunction with a drip edge flashing to prevent water from getting under the roofing and onto underlying wood. This will keep rain away from your shed. However the suggested width of an overhang is between 12 and 18 for eaves and no more than 8 for rakes. That said overhangs can extend as far as 2 without the need for external supports.

This can make extensive roof overhangs more trouble than they are worth in all but the harshest climates. This will protect a roof from most types of damage. A standard overhang is 16 24 inches but the overhang can be any length you wish. 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.
