Hand tools Day One Continued You need to decide if the pitch you have chosen for the roof will look good. Example: A 6:12 pitch is a 6" of rise for every 12" of run. Rise is vertical measurement and run is horizontal measurement (figure A -- an illustration of the portico's pitch). - Once you know the pitch you want, you can mark where your birds-mouth will be on your rafters. This will be the template for the rafters.
- Caulk the gaps in your sheathing and replace the house wrap.
- Cut the first set of rafters with the angle measurements. Rafters should be cut 3/4" short to leave room for the ridge board. Notch out a birds-mouth where the rafter will sit on your base.
- For the ridge rafter (figure B -- in helper's hand) first measure for the joist hanger. Line up a rafter against the house and then measure 7/8" from the center line to make room for 1-3/4" micro-lam ridge board.
- Hang your joist hanger and check to make sure you are level.
- Put a temporary brace on the center of the front rim board to hold the ridge rafter on the gable end. Center it on your front rim board.
- Install the ridge board at the temporary bracing. Start at the cleat end (figure C) and nail your rafter boards right onto the exposed sheathing using 16-penny nails.
- Measure out the spacing for the rest of your rafters. [Ryan marked his on 16" from the center.]
- Make the mark on the base of the frame and the ridge board.
- The "common rafters" are cut the same as the first rafters and you just toe-nail them in place (figure D).
- Finish nailing in the gable end rafters.
- Square the box by measuring from corner to corner. It should be an equal measurement in both directions.
- Attach the bottom of the rafters to the rim by toe-nailing them, using big old pole-barn nails (figure E). This will create a bigger hole.
- Attach the sub-fascia boards on both sides and then attach your fly rafters -- these are the same as the rest of your rafters but without the birds-mouth.
- Put on the outer fascia boards (the 1-by pine that was pre-primed). You can tack up a couple and then scribe and cut out some outer fascia boards for the front peak of the portico and put them up.
