Some barns require at least one come along as a permanent fixture strung across the haymow to keep them from continuing to buckle outward. The help of a second or third person is necessary even to lift a truss onto a single story roof. Sagging rafters are a sign that a house is in serious trouble. If your roof is seriously sagging you may need a come along in order to winch the sides of your building back into place before you add bracing.

If you have just stepped outside your house and realized that your roof is no longer straight this could signal a problem. Depending on the degree of sagging your contractor might need to use jack posts to raise the roof before installing any reinforcement. When sagging gets too severe it can lead to roof collapse and once the roof goes the house won t last for long. It is best to brace the inside of the trusses before handling them.

Use a t brace to support the truss vertically. Another approach is to give more support to the walls by installing chains attached to the wall plates and linked in the middle with a turnbuckle. Sagging rafters can lead to serious problems with the entire roofing system. Install 2x4s at a 45 degree angle.

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. No matter what the reason when you see a house with a sagging roof it tends to make you nervous even if you don t know precisely why. Undersized rafters also can cause sagging along the whole side or plane of a roof. If the framing is sound and problems are not found elsewhere but the roof still sags the problem might have originated because of poor installation of the plywood sheathing or shingles.

A ridge that droops in the middle forming that unintentional western design feature likely is due to undersized rafters and or missing or inadequate internal bracing rafter or collar ties. Being nervous about a sagging roof is understandable. Incomplete photos but enough.
