Jacking Up A Barn Roof

Once you have established how much the roof sag needs to be jacked up lay a 2x4 plate across the ceiling joists and nail directly under the ridge of the roof.

Jacking up a barn roof.

The small beams are attached to the side of the bents with steel plates says tom. With the large beams in place workers cut five holes in the side of the barn and slid in five smaller beams one next to each bent the transverse supports inside the barn. Seems to me the dormer rafters should have gone to the rige instead of having that small amount of roof coming down to that beam. We started where the roof showed the least amount of damage.

Jacking up a porch roof at a sidewall. You may remember my postings last year on. Drive the remaining carriage bolts into the two by six rafter and tighten them all up. Placing the bottom part of the first brace using a 2x6 and a floor jack we gently pushed a small section if the roof into level.

Now add collar ties from one side of the rafter to the other. This is the 3 rd time we ve jacked up a portion of this house. Place the jack back underneath the beam but this time under the iron piece. Stage 1 step 1 jacking up the first section of roof.

Measurements for materials were taken this way because of wooden blocks already attached to rafters. The smaller beams rest on top of the large front to back beams. First perform step 2 except keep the string under your beam and off to the side a bit to make room for some framing. So i found myself having to jack up one corner of our front side porch roof.

Remove the jack quickly and set the iron onto the entire beam. Then lower the jack down a little at a time so that the metal can take the weight of the roof.
