Strengthening Roof Rafters

Take 2 6x4 as long as your longest stored lumber and cut 2 inch deep grooves in them as wide as your 2x6 is thick every foot or so.

Strengthening roof rafters.

Use a circular saw to cut two sets of new rafters from the same size wood by the same dimensions. The roof rafters provide integral structural support to the roof. If your roof is strong enough it can extend beyond the support walls without external bracing. If you re framing a gable roof on a new house or building a shed or even a doghouse with a gable roof you ll need to cut a number of roof rafters.

Repeat the process for the joist beneath your old roof rafter. Drive the remaining carriage bolts into the two by six rafter and tighten them all up. Measure the dimensions of the old rafters beneath your roofing surface. Then lower the jack down a little at a time so that the metal can take the weight of the roof.

If you are building trusses it is easy to make part of the roof into a cantilevered extension. Install these over your existing horizontal 2x6s 2 feet from the roof edge inside and paralel to the roof ends crosswise from your existing 2x6. This is a fairly basic project that can help protect your roof but consult a structural. Before you cut your boards you ll need to measure the width of your building and calculate the exact length of each rafter.

Place a long piece of framing lumber alongside the. Just make one of the rafter members extend beyond the cross tie. Use your tape measure to record the distance of both rafter legs. Measure the thickness width and length of the rafters in your home and purchase one piece of framing lumber of.

If there are other rafters that need to be repaired follow the same procedure for each one of them. You can strengthen the roof to prevent damage by adding braces to the roof rafters inside your attic.
