Jacking Up A Barn Roof

Jacking up a porch roof at a sidewall.

Jacking up a barn 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. Place the jack back underneath the beam but this time under the iron piece. Drive the remaining carriage bolts into the two by six rafter and tighten them all up.

Best approach to jack up a sagging ridge i have pushed a few ridges back up by jamming 2x6s under the ridge at 4 to 6 foot centers. The smaller beams rest on top of the large front to back beams. This time i was jacking the porch roof up so i could install my final and last portion of half round gutter. So i found myself having to jack up one corner of our front side porch 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. This is the 3 rd time we ve jacked up a portion of this house. First perform step 2 except keep the string under your beam and off to the side a bit to make room for some framing.

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. I assume the steel you put in is the length of the house. Now add collar ties from one side of the rafter to the other. You may remember my postings last year on.

Stage 1 step 1 jacking up the first section of roof. 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.
