Trim rafter tails after placement For a good straight fascia, add an extra 20 mm or so to the tails of all your rafters (total length). After they're up, you can snap a line to mark and trim the tails in a nice straight line, to make up for any ridge warp or marking, cutting and fixing errors.



All running measurements are 'and on', from start point to near side of rafter.
Running Ridge: Mark out


Running Wall: Mark out
