Reinforcing a sagging gable roof.

You will need to remove the shingles and the old decking however which means there will be an exposed hole in the roof. The other is just used to support the trusses. These are usually accomplished during a complete re roofing. A great deal depends on the pitch of the roof.

Third install a shutter over any vents on the gable end wall. This is where a high pitched roof is necessary. Should the bottom cord of one or more trusses be sagging or damaged it may be reflected in a sagging ceiling or if the roof is over loaded to heavy then the downward pressure may cause the sagging. If you notice that there is a visible dip in your roof chances are you have a problem with one or several rafters and you may soon be facing more issues like water leaks bowed out walls or your roof caving in on you.

Sagging rafters may be the result of having framed the roof with lumber of dimensions smaller than current building standards such. Once again a 2 by 4 inch piece of lumber is placed between the trusses and parallel to the ceiling joists. Sagging ceiling could be an indication of framing issues some of which could be related to the roof. Reinforce your roof a properly constructed roof in areas subject to high winds has trusses attached to walls with hurricane tiedowns properly nailed sheathing and heavy duty shingles.

Use your string line to determine how much the roof need to go up. If the sagging roof is due to rotting or warping roof decking the repair will be much easier. This may be problematic in winter months but allowing the roof to continue to sag can lead to greater problems such as a cave in. This creates a solid unit of wall framing from the ground through to the roof on the gabled end of the house.

Sagging rafters can lead to serious problems with the entire roofing system. Sagging sheathing between rafters may be due to rot delamination use of fiberboard or other materials that may not perform well over the life of a home or due use of too thin plywood roof decking to start with.
