Pole Barn Truss Broken From Snow Load — Shored and Repaired
Late winter, a heavy snow and a crack you heard from the house. A truss in the barn has a split chord and the roof line has a dip. Stay out from under it; here is what happens next.
When a pole barn truss is broken from snow load, JMB Builders shores the roof under it the same week, gets the snow load off safely, and repairs the broken chords or webs to an engineer's repair letter with scabbed or sistered lumber and gusset plates, then adds bracing. North metro and central Minnesota, priced per project from photos, with the permit when the job needs one.

Pole barn trusses break from snow for a few reasons: heavy wet snow or drifting on one side, a truss that was damaged or cut years ago, missing or loose bracing that let trusses roll, or a knot in the bottom chord that finally let go. It shows as a sag in the roof line, a cracked chord, a web pulled off its plate, or steel buckled at the ridge.
First, safety. Nobody works or parks under it. The broken truss and the ones next to it are shored from the floor with posts and beams. Snow is removed from the roof carefully and evenly, or the shoring holds it until it melts; unbalanced shoveling can overload the next truss. Photos go to your insurer.
A broken truss is repaired to an engineer's letter, not guessed at. Trusses are engineered parts, and a cracked chord needs a repair designed for that truss: scabs or sisters of new lumber on both sides, bolted or nailed to a pattern, sometimes with new gusset plates, or a whole new truss slid in. Permanent bracing is added across the trusses so they share load. Structural work usually needs a building permit, and JMB pulls it.

What JMB supplies
- Emergency shoring under the broken truss and the trusses next to it
- Snow removal plan from the roof, or shoring left until it melts
- Engineer's repair letter for the broken truss
- Scabbed or sistered chords and webs, gusset plates, or a replacement truss per the letter
- Permanent bracing across the trusses
- Steel and trim repaired where buckled, permit when needed, and photos for your claim
How it is priced: per project
Quoted in writing from your photos within one business day. What moves the number:
- Number of trusses broken and how badly
- Shoring needed and how long it stays in
- Engineer's repair design versus a replacement truss
- Truss span and eave height, and access with a lift
- Roof steel, ridge cap and trim bent by the sag
- Bracing added across the rest of the trusses
Photos of the break from below and the roof line from outside let us plan the shoring before we arrive. Say if the roof is still loaded with snow.
How long it takes
Shoring: as soon as we can get there, usually within days. Repair: once the engineer's letter is in, one to three days on site for most barns.

Pole Barn Truss Broken From Snow Load — Shored and Repaired: questions, answered
What do I do when a pole barn truss breaks from snow load?
Get people, animals and equipment out from under it. Do not climb on the roof. Photograph the break and the roof line, call your insurer, and get the truss shored from the floor as soon as possible. Snow comes off evenly or waits until the shoring is in.
Can a broken pole barn truss be repaired or does it need to be replaced?
Most broken chords and webs can be repaired in place with sistered or scabbed lumber and new plates, to a design an engineer writes for that truss. A truss that is broken in several places or has dropped far is sometimes replaced. The engineer's letter says which.
Do I need an engineer to repair a broken truss?
Yes. Trusses are engineered parts, and the repair of a broken chord has to be designed for that truss and load. The engineer's letter spells out the lumber, fasteners and pattern, and it is what a building permit and your insurer go by.
Should I shovel snow off my pole barn roof after a truss cracked?
Not from the roof over a broken truss, and never unevenly. Shoveling one side can shift the load to the next truss. Shore the broken truss first, then take snow off in an even pattern from a safe spot, or leave it until the shoring is in and it melts.
Why did my pole barn truss break under snow?
Heavy wet snow or drifting on one side, a truss damaged or cut years ago, missing bracing that let trusses roll, or a weak spot in the lumber. Older barns built for lighter loads are more at risk. The repair adds bracing so trusses share the next heavy snow.
Does insurance cover a pole barn truss broken by snow?
Many policies cover collapse or damage from the weight of snow and ice, but farm and outbuilding coverage varies. Photograph it before anything is moved and call your insurer. We give you the photos, the engineer's letter and a line-item quote for the claim.
