Roof raferts repair.

Cut away rotten or damaged rafters. The cost of repairs depends on the amount of structural damage and materials required to repair it. You will drill two holes in the bottom and two holes in the side. Assuming it s in good shape you can leave it in place and install the new materials around it.

Place a length of 2 by 6 inch wood on the underside of the rafter ends so it bridges several of them and nail it to each one from below. Obviously this is not a good situation as it can cause the entire roof to fail if not addressed. If you see a rotted rafter you should take steps to identify the source of moisture that is causing the decay. Unless you have advanced carpentry skills you may not be able to fix a rafter with serious decay problems.

You will attach the l channel to the rafter before you attempt to repair the rafter. You should attach the l channel only in the four holes furthest away from the damage. The most reliable repair consists of affixing a length of metal angle at the lower edge and one side of the rafter. Generally a roof truss is composed of triangular shapes for proper support of the roof.

This includes repairing any leaks in the roof above the rafter. Repairing a roof truss often requires replacing or reinforcing wood in its construction. To increase the strength of your new and existing rafters and to help eliminate the chances of sideways movement consider installing a support board across the rafter endings on both sides of the roof. A cracked or damaged rafter due to a defect in the wood or an impact from an outside force may be able to be repaired preventing a very costly roofing repair.

It may also include replacing roof sheathing. If it shows signs of rotting water damage or other wear you ll need to chop it out using a reciprocating saw. Sagging rafters can lead to serious problems with the entire roofing system. Repairing this is called scabbing.
