How much overhang for roof sheathing.

Roof sheathing overhang on fascia. Because this style of a shed has a flat roof it can facilitate a wider overhang which is ideal for storage. Metal is usually installed on rafters or strip sheathing rather than the solid decking used under other materials. Some slight overhang is recommended in conjunction with a drip edge flashing to prevent water from getting under the roofing and onto underlying wood.

The size of the roof overhang you choose depends largely on the style of your shed s roof. Spacer type panel edge clips are available from some manufacturers. I ve trimmed my roof sheathing to run between 5 8 and 3 4 over the sub fascia. A typical metal roof overhang may be 2 to 4 inches or even less.

This is to just enough to cover the 3 4 x6 actual fascia. Use a 10d box 0 128 inch by 3 inch nail as a spacer to gauge 1 8 inch edge and end spacing between panels. With a flat shed roof the roof simply extends past the wall plate to provide an overhang. 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.

The roof s sheathing helps to keep the roof trusses or rafters properly spaced and is the strength that holds.
