Old roof new roof joined rafters fix.

If a roof has been re roofed with heavier roofing material than the original roof was engineered for. Use a circular saw to cut two sets of new rafters from the same size wood by the same dimensions. Use your tape measure to record the distance of both rafter legs. Move the jack in increments of one inch to allow for the roof to be able to move with it without cracking.

Cut a piece of 1 2 inch plywood that will cover the area. Measure the dimensions of the old rafters beneath your roofing surface. The new part of the roof system can be erected both above and below the old elements of the roof. Repeat the process for the joist beneath your old roof rafter.

When repair is no longer an option the roof rafters must be replaced. Then the beam or roof may sag. 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. 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.

Wood rotting from the inside out compromises the structural integrity of the rafter. Notice the rafter spreader bolt. The easiest way to straighten rafters is to jack them into position. Measure the damaged area between your roof rafters or trusses.

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. To avoid this there are additional pads on the connection phase with a base. This project requires two parts. Save those old shingles and number them for replacing later.

Strengthening can occur when the middle rafters have too much load that threatens to break the beam. First remove the rotten wood and then replace it with new rafters. Attach to the rafters using metal clamps or serrated plates.
