Commercial roll-up door repair: coiling, sectional, fast or fire-rated?
A coiling door is one continuous curtain — usually interlocking steel slats, sometimes a single sheet — that rolls up around a barrel in a hood above the opening. No hinged panels, no overhead track running back into the building. That's this page.
Getting this right matters because the wrong call sends the wrong technician with the wrong parts. Here's how the four sort out:
| If you see this | It's this | Where it goes |
|---|---|---|
| One curtain of slats or sheet metal coiling into a hood above the opening | Coiling / rolling-steel / roll-up door | This page |
| Hinged horizontal panels running back into the building on tracks | Sectional overhead door | Commercial garage and overhead door repair |
| Fabric or rigid door that opens fast, often at a cooler, freezer or high-traffic opening | High-speed door | High-speed and cold-storage door repair |
| A coiling door carrying a fire-rating label, or one listed in the building's fire-door records | Rated rolling fire door | Rolling fire door repair, inspection and testing |
That last row needs care, because a rated fire door and an ordinary coiling door can look nearly identical from the floor. A rated assembly has its own parts, its own inspection requirement and its own records. Treating it like an ordinary curtain swap is a real problem, not a paperwork one.
What a coiling door is made of
Useful vocabulary, not a requirement. Skip it if your door is down and you just need to call.
| Part | Where it is | What people also call it | What to say if this is the problem |
|---|---|---|---|
| Curtain | The door face itself — interlocking slats, or one continuous sheet | Slats, curtain, sheet | Whether it's bent, creased, punched or out of line, and roughly where |
| Guides | The vertical channels up each side that the curtain runs in | Tracks, guides, side rails | Which side the curtain came out on, and how high |
| Barrel and counterbalance | The tube above the opening that the curtain wraps around, with springs inside it that carry the door's weight | Barrel, drum, shaft | Only that the door feels heavy or won't stay up. Do not open the hood |
| Brackets and end plates | The steel plates at each end of the barrel, holding it to the wall | End brackets | Whether anything looks shifted or loose at the top corners |
| Bottom bar and astragal | The bar across the bottom edge, with a rubber seal | Bottom bar, bottom rail | Whether it's bent after an impact, or won't seat on the floor |
| Hood | The cover over the coiled curtain | Hood, canopy | Whether it's dented or the curtain is rubbing inside it |
| Operator, chain hoist or crank | The powered unit, the chain-and-sprocket hoist, or the hand crank that raises it | Motor, chain hoist, operator | Whether it turns and the door doesn't move, or nothing happens at all |
Commercial coiling-door manufacturer examples include Cornell, Cookson and Overhead Door. Use an existing record or a label already safely visible without approaching failed equipment — it's an identification help, not a claim about authorized service or who we work with.
What's it doing? Symptoms and what a provider checks
| What you're seeing | What a qualified provider may inspect | Why it matters | How to report it |
|---|---|---|---|
| Curtain out of the guides on one side | Curtain, guides, barrel and counterbalance | Forcing it back can crease slats all the way across and turn a repair into a replacement | "Curtain jumped out on the right, about six feet up" |
| Curtain bent, creased or punched after an impact | The damaged area, the slats either side, and the guides | Damage in a coiling curtain travels. A crease in one slat often means the ones around it took load too | "A forklift hit it at chest height" |
| Door jammed partway and won't move | Curtain, guides, barrel, drive | Something is binding. Running the operator harder usually makes it worse | "Stuck about halfway, won't go either way" |
| Door comes down crooked or drags | Guides, curtain alignment, barrel and counterbalance | A curtain running out of square wears guides and slats fast | "It comes down at an angle and scrapes on the left" |
| Loud noise, then the door dropped | Counterbalance and the components under load | This is a stored-energy system. Keep clear of the opening | "There was a bang and it dropped" |
| Bottom bar bent | The bottom bar, the seal and the guides it runs in | A bent bottom bar won't seat, so the door won't seal or latch properly | "The bottom bar is bowed in the middle" |
| Chain hoist spins but the door doesn't move | Drive, sprockets, chain and whether the curtain is jammed | The drive and the door are separate. The noise doesn't tell you which one let go | "The chain turns but nothing happens" |
| Door binds or scrapes through its travel | Guides, curtain, barrel and lubrication points | Binding usually means something is out of alignment before it becomes a failure | "It's been getting harder to lift for a month" |
If a coiling door has failed, keep people and equipment clear of the opening, don't force the curtain and don't keep running the operator, and take the opening out of use through whatever process your facility already uses. Never open a hood, adjust a barrel, or try to reseat a curtain — the counterbalance inside is under load.
What to say when you call
Here's example wording for a first call. It's an example, not a script, and not a real job.
"The coiling door at our Houston shop jumped out of the guide on the right side and it's stuck halfway."
Three steps after you call
- You describe it. Where the facility is, which opening, and what the curtain is doing.
- Your request may be shared. Calls may be shared with an independent commercial dock-and-door repair company.
- That company takes it from there. They confirm whether they can serve the address, what they can do, when, and what they charge — plus their own contract, work and warranty terms. If you reach voicemail, leave the facility address, the door or dock number if known, what's wrong, and a callback number.
Useful to have, not required
Which opening and roughly how wide it is. Whether the curtain is slats or one sheet. Whether it's manual, chain-hoist or motorized. Whether the door has a fire-rating label, if you already know that from the building's records. The brand, only from an existing record or label already safely visible. Don't approach the failed door to read it.
Call without any of it. The facility address, the opening, and "the curtain is out of the guides" are enough.
Roll-up doors at self-storage and smaller commercial buildings
Not every coiling door is on a distribution center. Commercial self-storage buildings, single-bay workshops, small warehouses and back-of-house openings at commercial buildings all use rolling sheet doors and light rolling-steel doors, and those are in scope.
What decides it is the building and the mechanism, not the size of the company. A commercial self-storage facility with a row of rolling sheet doors is a commercial building with commercial doors. A house with a garage is not, whatever the door is made of.
What we take calls about — and what we don't
In scope: building-mounted commercial coiling and rolling-steel doors, commercial rolling sheet doors, their curtains, guides, barrels, counterbalances, bottom bars, hoods, hoists and operators, at commercial and industrial buildings.
Not in scope, and here's who does handle it:
- Truck and trailer cargo roll-up doors → a trailer service shop. A roll-up door on the back of a trailer is vehicle equipment, not building equipment.
- Residential garage doors → a residential garage door company.
- Storefront security grilles used as pedestrian entrances, plus their locks and closers → a commercial door and hardware company or a locksmith.
- Boat docks and boat lifts → a marine contractor.
- Parts-only orders → a distributor.
- Structural concrete and masonry around the opening → a general or concrete contractor.
What affects the price, and repair versus replacement
We can't quote your exact roll-up door repair from a web page. The price depends on the curtain, the fault, parts, and access. Here's what to ask before you authorize work.
Ask about the diagnostic or service-call charge and whether it comes off the repair. Ask what the estimate covers. With a coiling door, ask one extra question: whether the proposal is for a section of curtain, a complete curtain, or the whole assembly — because those are very different numbers and it's easy to compare two quotes that aren't quoting the same thing.
| What drives it | Why it moves the number | What to ask |
|---|---|---|
| How far the curtain damage runs | A crease in a coiling curtain often means the neighbouring slats took load too | "How many slats, and how did you decide that?" |
| Slats versus a complete curtain | Individual slat replacement is possible on some doors and not others | "Is this a slat repair or a full curtain?" |
| Guides, barrel and counterbalance condition | The curtain may be the symptom, not the cause | "What did you find in the guides and the barrel?" |
| Door size and gauge | Bigger and heavier curtains change handling, labor and sometimes equipment | "Does the price assume a lift or a second tech?" |
| Manual, chain-hoist or motorized | The drive is its own scope | "Is the hoist or operator included?" |
| Parts lead time | Slat profiles vary by manufacturer and age. Some are stocked, some are made to order | "Is the part stocked, or is it on order?" |
| Access and working height | Overhead work at a live opening takes coordination and sometimes equipment | "Do you need the opening released, and for how long?" |
Repair or replace? Ask whether the damage is confined to replaceable slats or extends into the guides, barrel, support or operator. Compatible parts, the curtain's ability to coil correctly, the assembly's condition and any required rating determine the options. A dent or crease alone is not a remote diagnosis. Have the provider explain what can be repaired, what needs replacement, and why; field changes to a rated assembly need their own approval review.
Local rules that touch rolling doors in Houston
A repair label alone doesn't settle the permit question. The City of Houston's Building Code Enforcement office lists repairs among regulated work and directs applicants to the actual exemptions; the scope and address decide what applies.
For unincorporated Harris County, Fire Code §105.1.5 excuses applications or notice for ordinary repairs under that fire code, with limits for walls, egress, fire protection and life safety. It is not a blanket exemption from building, electrical or floodplain requirements. The same fire code's §105.1.4 calls for an emergency repair/replacement application within the next working business day; that does not waive a different authority's requirements.
Ask the Houston Permitting Center for a city address, or the County Engineer and Fire Marshal for an unincorporated Harris address, about the actual work. The independent provider and issuing office confirm the scope. Checked September 18, 2026.
A replacement, changed opening, operator circuit or rated fire-door assembly deserves its own scope question. Near the coast, distinguish the building's wind-design requirements from TDI's separate windstorm-certification program (TDI). The Houston installation page explains that boundary; the fire-door page covers rated assemblies.

Roll-up door questions from Houston facilities
What's the difference between a roll-up door and a sectional door?
A roll-up or coiling door is one continuous curtain that wraps around a barrel above the opening. A sectional door is built from hinged horizontal panels that travel back into the building on tracks. Different parts, different failures, different technicians carrying different things on the truck. A hood and coiling curtain are useful identification clues, but not proof of the drive type or fire rating. Report what you already know without approaching failed equipment.
How do I know if our rolling door is fire-rated?
Three ways, none of which require climbing. Look for a rating label on the door or frame from the floor. Check the building's fire-door inspection records — rated openings should appear there. And look at where it sits: rated rolling doors usually protect an opening in a fire-rated wall or separation between two parts of a building. If you're not sure, say so on the call. It's a normal thing not to know.
Can a bent curtain be repaired, or does the whole thing get replaced?
It depends on how far the damage runs and how the curtain is built. A dented slat or two low on a slatted curtain is often repairable. A crease running the full width usually isn't, because it changes how the curtain coils. A qualified provider has to look at it. Nobody can tell you from a photo, and nobody should tell you from a phone call.
The door came out of the guides — can we put it back ourselves?
No. The counterbalance in the barrel is under load, and a curtain that's partly out of its guides can move suddenly. Forcing it back in is also how a one-slat problem becomes a full-curtain problem. Keep people clear, leave it where it is, take the opening out of service through your normal process, and let someone with the right equipment reseat it.
