Pole Barn & Barn Repair Work in Hermann, MO
WHAT WE DO
Exposed-fastener metal panels seal with a rubber washer under every screw, and once those washers crack or screws back out, each hole lets water reach the framing. Arnsmeyer Contracting
provides pole barn and barn repairs in Hermann, MO, and the surrounding counties, tracing leaks, leaning posts, and wind damage back to the actual cause before fixing anything. Our repair work covers roof and wall panel replacement with matching profiles, sistered lumber and steel bracing for weakened framing, trim and closure strip replacement, and resealed connections. Most repairs wrap up within a few days, and our licensed, insured crew keeps the building usable wherever it safely can.
WHERE WE REPAIR
Weathered Barns and Wind-Worn Pole Sheds
Central Missouri buildings take a beating from spring storms, summer heat, and winters that freeze and thaw the ground again and again. Older wood barns show it in sagging rooflines and rotted sill boards, while newer pole sheds show it in lifted panels and posts pushed out of plumb by settling soil. We work on both across Hermann and nearby communities, from hilltop farms that catch every gust to lower ground where water collects around columns and slowly softens the wood below grade.
Barn Repairs We Handle
Every repair starts by finding the true source of the problem, then fixing it with materials and methods that hold up better than whatever failed the first time around.
01
Roof Panel Replacement
Dented, rusted, or wind-lifted panels come off and matching profiles go back on, fastened with fresh sealing screws. Replacing damaged sections rather than the whole roof keeps costs reasonable while stopping the leaks that ruin stored hay, feed, and equipment.
02
Siding Panel Replacement
Panels punctured by equipment, pulled loose by wind, or rusted along the base are removed and replaced with matching profiles. New closure strips and trim close the gaps where rain, snow, and animals were getting into the building.
03
Leaning Post and Column Repairs
A post rotted below grade or cracked through the grain needs replacement, while a sound post pushed out of plumb can often be braced. We identify which one you have and correct it before the lean spreads into the walls and roof.
04
Framing and Truss Reinforcement
Weakened girts, purlins, and trusses are strengthened with sistered lumber or steel bracing. Reinforcing the members that carry roof and wall loads restores stiffness, reduces sagging, and helps the building ride out future wind, heavy rain, and snow.
05
Fastener and Trim Repairs
Loose screws, cracked washers, and bent trim quietly let water in long before panels fail. Inspecting every connection, replacing worn hardware, and resealing trim around corners and openings stops slow leaks that eventually rot framing from the inside.
06
Storm Damage Repairs
High winds peel back panels, snap trim, and rack framing out of square in a single afternoon. After a storm, we secure the building, document what moved or broke, and repair the damage so the structure is weathertight and stable again.

Brandon and his crew did an excellent job building onto an existing building for us. Hard working crew. Quality workmanship! Definitely would recommend him! Always returns a phone call or a text message in a timely manner.

I always enjoy working with Brandon and his crew! His attention to detail, work ethic, and personable attitude makes for an all around great experience! Seeing his pole barns from start to finish, I can't recommend him enough!
James C.
Brandon built a lean-to on my shop for me. He did a fabulous job I would recommend him and use him again. In fact he is doing an addition to my daughter and son-in-laws house right now.
Randi M.
It was a big job, multiple projects and buildings, that took 8 months to complete. I highly recommended Arnsmeyer. Excellent work, and communication every step of the way. This crew went above and beyond.
Signs Your Barn Needs Attention Now
Most barn damage starts small and grows quietly. Catching these warning signs early usually means a smaller repair, a lower bill, and a building that stays useful instead of becoming a teardown.
01
Leaning Walls or Posts
A wall that tilts or a post that no longer stands plumb signals rot, soil movement, or failed bracing. Left alone, the lean shifts load onto other members and gradually pulls the entire frame further out of square each season.
02
Sagging Roofline
A dip along the ridge or between trusses means something below is weakening. Cracked trusses, rotted purlins, or sinking posts all show up this way, and heavy snow sitting on an already sagging roof raises the risk of failure considerably.
03
Water Stains Inside
Dark streaks on framing or wet spots on the floor after rain point to missing panels, lifted edges, or failed flashing. Tracking a stain back to its entry point early prevents rot from spreading into lumber that holds the building up.
04
Lifted or Loose Panels
Panels that rattle, flap, or show daylight at the edges are catching wind every time it blows. Each gust pries them further, so securing loose panels quickly keeps a minor fix from becoming a missing section after the next storm.
05
Rust Around Fasteners
Orange streaks running down from screw heads mean washers have failed and moisture is working into the metal. Replacing hardware before the rust spreads across the panel can add years to a roof or wall that otherwise looks sound.
06
Doors That Drag or Bind
When a sliding or walk-in door suddenly sticks, the opening has probably shifted. Racked framing, settling posts, or a sagging header are common causes, and the door is often the first place structural movement becomes obvious to owners.

Frequently Asked Questions
What are the most common causes of pole barn damage in Missouri?
Wind lifts roof panels, water works in through failed fastener washers, and settling soil gradually pushes posts out of plumb. Freeze-thaw cycles speed all three along, which is why small problems in central Missouri rarely stay small for long.
How do I know if a leaning post needs replacement or just bracing?
If the post is rotted below grade or cracked through the grain, it needs replacement. A solid post that simply shifted with the soil can often be straightened and braced, which is faster and less disruptive for the building.
Why do metal roof panels lift even when the screws are still in place?
Fasteners loosen over time as metal expands and contracts, letting wind slip under a panel edge and pry it upward. Once the edge lifts, each gust works it harder, so the panel eventually tears away around its screws.
Can one damaged truss be fixed without removing the roof?
Often, yes. A cracked or broken truss can usually be reinforced with sistered lumber or steel bracing, or replaced after the roof load is temporarily supported. The right fix depends on how badly the truss failed and what surrounds it.
Will replacement panels match the rest of my building?
Replacement panels are matched to the existing profile so they overlap and seal correctly. Color can be harder to match exactly on older, sun-faded panels, so placement is planned where slight differences are least noticeable from the ground.
Is it safe to keep using a damaged barn?
That depends on the damage. A small leak rarely creates a safety issue, but a sagging roof, cracked trusses, or badly leaning posts can fail under snow or wind. Keep people, animals, and equipment out until the structure is assessed.
Can a barn that has racked out of square be straightened?
In many cases, yes. Arnsmeyer Contracting pulls racked framing on barns around Hermann, MO, back toward plumb, then adds bracing so it stays there. Buildings with rotted posts or failed trusses need those members repaired before straightening can hold.
Should I fix barn damage before or after winter?
Before winter, whenever possible. Arnsmeyer Contracting recommends that owners in Hermann, MO, address loose panels, leaning posts, and weak trusses during fall, since snow load and repeated freeze-thaw cycles turn small defects into much bigger structural problems by the time spring arrives.
Keep The Barn You Have Standing Strong For Years To Come
A barn does not need to look new to do its job, but it does need to stay dry, square, and firmly anchored. Arnsmeyer Contracting repairs pole barns and older barns across Hermann, MO, with a focus on fixing the real cause, whether that is loose fasteners, rotting posts, or framing that has started to give. A well-timed repair often costs a fraction of replacement and buys the building many more working seasons. Take a walk around your barn, note what concerns you, and share those details with us.
