Jacking Up A Barn Roof

Measurements for materials were taken this way because of wooden blocks already attached to rafters.

Jacking up a barn roof.

This time i was jacking the porch roof up so i could install my final and last portion of half round gutter. 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. I assume the steel you put in is the length of the house. You may remember my postings last year on.

Place the jack back underneath the beam but this time under the iron piece. 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. Remove the jack quickly and set the iron onto the entire beam. 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. First perform step 2 except keep the string under your beam and off to the side a bit to make room for some framing. This is the 3 rd time we ve jacked up a portion of this house. 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.

Now add collar ties from one side of the rafter to the other. The small beams are attached to the side of the bents with steel plates says tom. So i found myself having to jack up one corner of our front side porch roof. Then lower the jack down a little at a time so that the metal can take the weight of the roof.

Drive the remaining carriage bolts into the two by six rafter and tighten them all up. Stage 1 step 1 jacking up the first section of roof.
