My original plywood template of the roof surface gave me the prow length 3.
Installing roof lookouts.
Stock 184862584 1024x674 1024x674 jpg alt how to install roof lookouts title how to install roof lookouts i had to figure out the pitch of the prow so i needed to find the horizontal run of the prow fascia to complete the equation.
Hoist a supply of 2 4 lookout stock up to the roof set each lookout in its notch and secure the end of each one against the face of the first inboard truss or rafter with two 16d nails.
To install the barge rafter i pushed the top end tight against the ridge and ran it past the ends of the lookouts and the subfascia.
I also knew the vertical rise.
Or the crazy framers who sheath the roof with 7 16 sheets.
After nailing the barge rafter at all those points i cut the bottom end flush with the outside face of the subfascia.
But once i start using a nice and straight 2x6 sub fascia and i usually send a deck screw into about every 3rd rafter tail to hold things snug and then sheeting with 5 8 sheets the lookouts aren t really adding much to the structural integrity of the eaves.
