Decking & Sheathing

Can I use solid decking for my shake or shingle application?

Shakes and shingles may be applied over spaced sheathing. Spaced sheathing is usually 1 x 4 or 1 x 6 softwood boards and shall not be less than 1 x 4 boards. Solid sheathing is recommended for shakes and may be required in seismic regions or under treated shakes and shingles. Solid sheathing is used in areas with wind-driven snow. Please note that the only solid sheet sheathing tested with shakes and shingles is plywood. Check with your local building official for plywood thickness/ dimensions. See the CSSB's New Roof Construction Manual.

What is the difference between "decking" and "sheathing"?

The two words are used interchangeably in the roofing industry.
