I can't lay my hands on the book right now because I don't even remember which one it is, might be the big one from OHJ, but one of my old-house-repair books discusses replacing rotted rafter tails.
Step 1
Set up your ladder on level, stable ground near the area of the roof with the rotted rafter tails.
Step 2
Pry away rain gutters by removing either the metal strapping that holds them to the fascia boards or the long metal spikes that fix them to the fascia with the end of a hammer. Set the gutters aside.
Step 3
Remove the nails from the fascia board covering the rafter ends with the end of a claw hammer. Also remove the soffit material covering the bottoms of the rafters, if applicable.
Step 4
Examine the rafter tails to determine the extent of the damage. When the soft, rotted areas are confined to the very ends of the rafters, you can repair the rafters without disturbing the roof.
Step 5
Remove the shingles, underlayment and plywood sheathing directly over the rotted rafter tails if damage extends more than few inches from the end of the rafters.
Step 6
Measure the length of the overhang with a measuring tape, from the exterior wall to the end of the rafter in the case of a badly rotted rafter tail, or for a rafter with rot someplace other than its end. Measure the rotted portion of a rafter with damage confined to its last few inches.
Step 7
Cut a length of 2-by-4 or 2-by-6 lumber, depending on your rafter dimensions, to twice the length of the damage for a small repair, or three times the length of its overhang, advises carpenter Jack LeVert in "Fine Homebuilding" magazine's book "Roofing." Skip to Step 9 if your repair is just to the tail end of the rafter.
