mbon Posted April 4, 2012 Share Posted April 4, 2012 How do I find the area of sheathing, rather than the flat area of a roof object? Quote Link to comment Share on other sites More sharing options...
Dana W Posted April 4, 2012 Share Posted April 4, 2012 The sheathing area (finished) would be the area of each plane of the roof structure added together. For instance, each side of a straight gable end roof is two planes on angle. Find the area of these two planes and add them together. Rafter length including facia x ridge length including facia x 2. In the real world though, you actually need to know how many full size sheets of sheathing you need to buy to cover the roof before they are cut up.
