How to Fix a Sagging Ridge Beam
A ridge beam runs horizontally across the top of the roof on the interior of a home. Ridge beams are most often found in attics at the peak of the house. They help hold the rafters in place that meet at the top of the roof. Ridge beams are made out of 2-by-8 or 2-by-10 pieces of lumber. They are installed directly to the rafters above them. Over time, the ridge beam can begin to sag, due to weight or pressure on the roof. If your ridge beam is sagging, it must be fixed immediately before your roof is completely ruined.
Climb up to the attic or other area of the house where the ridge beam is located. Start at one end of the attic and walk toward the other. Inspect the ridge beam and locate exactly where the sagging is taking place. Position a ladder underneath and climb up it, if necessary to see the sagging.
Inspect the area that is sagging closely and find all the screws that are holding the ridge beam in place. Tighten any screws down that have come loose over time with a power drill. Fasten the screws down until they are flush with the ridge beam you are installing them into.
Place rafter ties on each side of the ridge beam and the rafter above it. This will help strengthen the beams to the rafters. Rafter ties are similar to L-brackets, but are shaped at an angle so they can attach to the rafters and ridge beams.
Insert wood screws through the predrilled holes and secure the rafter tie in place to the ridge beam and the rafter. Repeat the process for the rafter tie on the other side of the ridge beam. Move down the beam and add rafter ties wherever the beam is sagging.
Inspect the sagging beam and add more screws to the area that is sagging, if necessary. Drill in wood screws that are 3-4 inches long. This will ensure the beam is properly secured to the rafters above.
