How Much Overhang For Roof Sheathing

Then i do a metal drip edge to cover it all.

How much overhang for roof sheathing. A typical metal roof overhang may be 2 to 4 inches or even less. 8d ring shank nails should be used instead. Measure up the rafter 45 3 4 inch from the cut end of the truss tail and snap a line along the trusses. This indicates the upper edge of the first row of roof sheathing leaving enough overhang that the subfascia and fascia will tuck neatly underneath when the time comes.

Metal is usually installed on rafters or strip sheathing rather than the solid decking used under other materials. Never attach roof sheathing with staples. Sheathing should be a minimum of 19 32 inch thick. I ve trimmed my roof sheathing to run between 5 8 and 3 4 over the sub fascia.

The typical thickness range for sheathing is 3 8 to 3 4 inch. The roof sheathing comes down and ends on top of the 1 x fascia. On my shed my sheathing does not protrude actually how both my house and shed are done is a 1 x 6 house 1 x4 shed fascia is installed to end of rafters then 1 x 1 1 2 is tacked onto the fascia at the top. That said overhangs can extend as far as 2 without the need for external supports.

It is at 45 3 4 in. This is to just enough to cover the 3 4 x6 actual fascia. Roof sheathing comes in grid marked 4 by 8 foot sheets and should be installed perpendicular to the frame. Overhangs can vary from a few inches to a few feet depending on preference.
