How Wide Should A Roof Overhang Be

The floor of a porch looks different with wide plank wood decking than with concrete or tile.

How wide should a roof overhang be.

The diagonal measures are actually relatively easy to get equal as it takes very little effort to shrink a long diagonal by several inches. A typical metal roof overhang may be 2 to 4 inches or even less. 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.

Roof overhangs are the amount that the roof hangs over the top of the siding in residential home construction. A shed overhang is an easy and effective way to protect your shed. The board can be as narrow as 2 in. Some slight overhang is recommended in conjunction with a drip edge flashing to prevent water from getting under the roofing and onto underlying wood.

That said overhangs can extend as far as 2 without the need for external supports. You can add 3 to 5 inches to the top. Do not minimize the importance of architectural elements like arched stonework at the window heads and stone sill. The typical maximum overhang is 2 feet.

And as wide as 8 in with the bead detail also varying. The detail should be in scale to the house and the porch itself. They keep the drip line of the edge flashing away from the plane of the bricks. Many of these elements including overhang details may be only some inches wide say 10 12 14 or 16 inches wide but are critical anyway.

Metal is usually installed on rafters or strip sheathing rather than the solid decking used under other materials. Hunker may earn compensation through affiliate links in this story.
