Old Roof New Roof Joined Rafters Fix

Use a circular saw to cut two sets of new rafters from the same size wood by the same dimensions.

To avoid this there are additional pads on the connection phase with a base. However the trick to this process is to do it very slowly so it may take a few weeks before you get the rafter into a position where it is straight again. First remove the rotten wood and then replace it with new rafters. Because driving nails up into the sheathing material will make things worse glue a piece of 1 inch rigid styrofoam to your piece of plywood.

Use your tape measure to record the distance of both rafter legs. Notice the rafter spreader bolt. Then the beam or roof may sag. Move the jack in increments of one inch to allow for the roof to be able to move with it without cracking.

Repeat the process for the joist beneath your old roof rafter. This project requires two parts. Strengthening can occur when the middle rafters have too much load that threatens to break the beam. When repair is no longer an option the roof rafters must be replaced.

High enough to give room to nail the mid span cross tie at the desired location. If a roof has been re roofed with heavier roofing material than the original roof was engineered for. With the roof rafter pair straightened clamp new mid span cross ties in place and then nail the tie ends to the rafters. Save those old shingles and number them for replacing later.

Attach to the rafters using metal clamps or serrated plates. I e the original roof was a light wood shingle roof and the new replacement roof is a concrete tile roof weighing 5 or 10 times more than the original roof. Starting two courses higher than where the new ridge meets the old roof unseal the shingle tabs a thin flat bar or a joint taping knife works well and pop the nails of the overlying course. Measure the damaged area between your roof rafters or trusses.

The easiest way to straighten rafters is to jack them into position. Measure the dimensions of the old rafters beneath your roofing surface. Wood rotting from the inside out compromises the structural integrity of the rafter.
