Raising Sagging Roof Rafters

The first step is to find out how many rafters are sagging and if anything else is damaged.

Raising sagging roof rafters.

Place the plywood and styrofoam side up against the damaged roof decking. So you should start by inspecting the roof from the under side or attic. If there is any other damage it should also be fixed before moving to the next step. Determine the extent of damage.

Actuate the intensity of damage. Place a fascia board up under the roof sheathing and nail it with a hammer across the ends of the rafters to strengthen them. Spread polyurethane glue into the crack with a stiff bristle brush. The first and foremost step is to find out how many and from where the rafters are sagging.

Keep the plywood in place using a piece of lumbar strapping until you can get a roofing expert to repair it. Sagging rafters may be the result of having framed the roof with lumber of dimensions smaller than current building standards such as using 2x4s or 2x6 s or there may be damage to the framing from insects or rot. You may find that. Drill holes in angle iron.

Remove the chisel and wet the crack with a wet rag. If the damage is identified then it will be easy to repair it.
