Rolling, sectional, or something faster?
Three doors get called by each other's names, and getting it right saves a wasted visit.
A rolling door is a curtain that coils into a barrel above the opening. A sectional door is hinged panels that travel back overhead on horizontal tracks. A high-speed door is usually fabric or a light rigid curtain moving several times faster than either.
- Curtain that coils into a barrel → this page.
- Hinged panels on overhead tracks → commercial garage and overhead door repair.
- Fast fabric or light rigid curtain → high-speed and high-performance door repair.
- A rolling door with a label, a fusible link or a release mechanism → that is a fire door, and it is a different obligation. Rolling fire door repair and drop testing.

Four rolling door families, and why the difference matters
They all coil. They are built differently, they fail differently, and they are covered by different product standards.
| Family | What it looks like | Where you see it | Its product standard | What tends to fail |
|---|---|---|---|---|
| Non-fire-rated rolling steel door | A curtain of interlocking steel slats running in guides | Dock openings, exterior service openings, secure bays | DASMA 203-2020, Standard for Non-Fire Rated Rolling Doors | Impact damage to slats and the bottom bar, end locks, guide binding, counterbalance |
| Rolling sheet door | A single formed steel sheet, lighter duty | Interior openings, light exterior openings, smaller bays | DASMA 207-2018, Standard for Rolling Sheet Doors | Curtain deformation, guides, spring tension |
| Rolling grille | Open lattice rather than a solid curtain | Openings that have to stay ventilated or visible | DASMA 208-2018, Standard for Rolling Grilles | Linkage and rod damage, guides |
| Fire-rated rolling door | Labelled, with a release mechanism and a governor | Rated openings and fire separations | DASMA 204-2025, Standard for Fire Rated Rolling Door Assemblies | Covered on the fire door page, not here |
Standard designations and titles from the DASMA standards index, checked 21 September 2026.
Names that commonly appear on commercial rolling doors include Overhead Door, Cornell, Cookson and Janus, among others. Those are identification examples to help you recognize what you have — not a claim about what is installed around Buffalo, who services which brand, or any dealer relationship. You do not need the name to call.
What the symptoms usually mean
| What you see or hear | What a qualified provider may inspect | Why it matters | How to report it on the call |
|---|---|---|---|
| The curtain binds or jams partway | Slat condition, end locks, guides, barrel, counterbalance, debris in the guides | A bound curtain can be impact damage or a counterbalance problem, and those get handled differently | "It stops about halfway" |
| The curtain is bowed or dented | Slat damage, bottom bar straightness, guides, mounting | Impact usually reaches more than the slat you can see | "A forklift caught it" |
| The door will not come down | Counterbalance, controls, limits, obstruction, guides | A door stuck open is an exposed building, and in winter that is a heating problem too | "It's stuck open on the shipping bay" |
| The door drifts down on its own | Counterbalance adjustment, clutch, brake, balance | A drifting door can come down into an opening where a vehicle can hit it | "It creeps down by itself" |
| The bottom bar is bent or will not seat | Bottom bar, astragal, guides, floor condition, curtain squareness | A door that does not seat does not seal, and it wears the guides | "It doesn't sit flat on the floor" |
| A loud noise, and now the door will not hold | Counterbalance springs, shaft, brackets, barrel | Stored energy has already failed once | "We heard a bang and now it won't stay up" |
| The hand chain suddenly takes two people | Counterbalance, bearings, guides, curtain binding | Published guidance puts hand chain operating effort at no more than 35 pounds of force and crank operation at 25 — if it suddenly takes two people, something changed | "It used to pull easy and now it doesn't" |
| The operator runs but the curtain does not move | Operator, drive connection, clutch, brake, limits | Power at the operator with no movement is a recognized recurring field problem | "The motor runs and nothing happens" |
| The door only moves while the button is held | Operator type, entrapment protection, sensors, wiring | Constant-pressure operation can indicate a required safety device is missing or faulted | "It only runs while I hold the button" |
Operating-effort guidance from DASMA TDS 270, rev. 6/21, checked 21 September 2026.
If the door is unsafe right now: keep people and traffic clear of the opening, do not force it and do not keep cycling it, and take the opening out of service using your facility's own process. That is the whole list. Curtains, counterbalances and barrels hold enough stored energy to injure.
Call and say which opening.
Operators, controls and sensors on rolling doors
A rolling door operator turns the barrel — usually through a drive on the shaft — and it works against a counterbalance that is supposed to be carrying most of the door's weight. When the balance is off, the operator is what wears out first.
Published industry guidance names a set of recurring field problems on motor-operated commercial sectional and rolling doors: a sensing edge miswired so it fails to stop or reverse on descent, electrical work started before the door was installed, expansion anchors used in hollow masonry where through-bolts are required, the wrong wiring diagram, conduit routed under a rolling door's drop arms, missing fire door release instructions, unbalanced doors wearing the operator, power present with no movement, and door drift from bad balance or clutch adjustment.
That list is worth having because it tells you what a good provider will actually look at, and it explains why "the motor's broken" is often not the answer. Source: DASMA TDS 375, rev. 8/21, checked 21 September 2026.
Do not open a control box, bypass a sensor or reset a tripped device. Report what the door is doing and let somebody with the training look at why.

Covered. Commercial roll-up, rolling steel, coiling and rolling sheet doors and rolling grilles at warehouses, distribution centers, plants, cold storage, food and beverage facilities, auto-service bays, fleet garages, workshops, commercial self-storage and other commercial buildings: curtains and slats, end locks, guides, bottom bars and astragals, barrels and counterbalance, brackets, hoods, hand chain and crank operation, operators, controls and safety devices.
Not covered.
- Residential garages — a residential garage door company.
- Boat docks, boat lifts and waterfront structures — a marine contractor. Not the same "dock."
- Truck and trailer cargo doors — a trailer or fleet repair shop.
- Storefront, automatic-entry, glass and hollow-metal walk-through doors with their locks and closers — a commercial door hardware company or a locksmith.
- Parts-only requests — a dock and door parts supplier.
- Structural concrete and masonry around the opening — a concrete contractor.
- Fire-rated rolling doors — the fire door page covers the testing and reset obligation those carry.
What happens when you call (385) 325-7138
1. You describe it. Which opening, what the door is doing, and whether something hit it. You do not need a model number, a measurement or a photo.
2. The details go to an independent repair company. Independent service-request website. Calls may be shared with an independent commercial dock-and-door repair company. That provider confirms availability, scope, pricing, and service terms.
3. That company confirms everything with you — address, scope, whether it can take the job, when, price, and its 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.
Example wording, not a real job:
"The roll-up door on our shipping bay is stuck about halfway and the curtain looks bent — I can give you the address."
Call to describe the problem.
Useful on the call, but not required
Roughly how wide and tall the opening is. Whether the door is powered or hand chain. Whether it is an exterior or an interior opening. Whether something hit it, and roughly when. Any label you can read from where you are standing.
You can call without any of it. City, address, which bay and "it's stuck halfway" is enough. Do not walk over to a damaged door to collect details for this list.
What drives the price, and repair against replacement
We can't quote your roll-up door repair from a web page. The price depends on the door, the fault, parts, and access. Here's what to ask before you authorize work.
| What moves the price | Why | What to ask |
|---|---|---|
| The visit itself | Somebody has to see it before anybody prices it | "Is there a call-out charge, and does it come off the repair?" |
| A slat section against the full curtain | Replacing four slats and replacing a curtain are different jobs | "How much of the curtain is coming out?" |
| End locks and guides | Impact usually reaches the guides, not just the curtain | "Are the guides straight, or are they part of this?" |
| Counterbalance and barrel work | Spring and barrel work is the most specialized part of the job | "Is the counterbalance involved, and is it being re-tensioned or replaced?" |
| Operator and controls | Replacing an operator can bring safety-device requirements with it | "Does the operator need a monitored entrapment device?" |
| Bottom bar and astragal | The seal at the floor is what keeps weather out | "Is the bottom bar straight enough to reuse?" |
| Whether the opening can shut down | Working over a live dock costs more and takes longer | "Do you need the bay out of service, and for how long?" |
| Parts lead time | Some commercial parts are stocked regionally and some are not | "What's the realistic date, not the best case?" |
Ask which kind of number you are getting — a call-out fee, a starting price, a fixed price for a written scope, an estimate, or a committed quote. Those are five different things, and the trouble starts when a starting price gets treated like a quote.
Repair or replace? These are the factors that decide it, not a verdict from a web page:
- How much of the curtain is damaged, and whether matching slats are still available for that door.
- Whether the barrel, shaft or brackets took the impact — curtain damage is cheap next to a bent shaft.
- How many times this door has already been straightened.
- Whether the opening keeps taking hits. Published guidance recommends knockout or breakaway designs and impact-resistant guides where vehicle contact is likely, and that is a replacement conversation rather than a repair one.
- Whether the door's duty is above what it was specified for.

Rolling doors through a Buffalo winter
Two things do most of the damage here.
The first is a door that froze to the floor and got forced. The bottom bar bows, the curtain goes out of square, and the guides take the load. What a provider looks at is the bottom bar and astragal, the guides, the floor and drainage at the opening, and whether the operator has been run against a stuck door enough times to have worn.
The second is grit and salt in the guides. Ice, road salt and tracked-in debris build up at the bottom of the guide where nobody looks, and a curtain that runs a little harder each week eventually runs hard enough to bind.
Do not pry a frozen door up and do not run the operator against it. Call and say it is frozen — it changes what gets brought.
Licences and permits for this work in Buffalo
There is no New York State licence for commercial door work. Licensing is municipal, and it varies town by town — Buffalo licenses contractors in classes, the Town of Tonawanda and North Tonawanda license work that plainly reaches commercial repair, and Lancaster, the Town of Hamburg and Wheatfield require no contractor licence at all. Where an operator's line-voltage wiring is involved, the electrician's licence is the credential an inspector actually checks.
On permits, a straight repair to an existing rolling door is usually maintenance rather than construction — but New York lets the local authority decide, and changing the opening, the structure or a fire rating is a different conversation. The full rulebook is on the Buffalo hub page, and the installation page carries the permit and fee detail.

Questions about roll-up and rolling-steel doors in Buffalo
What's the difference between a roll-up door and a rolling steel door? In everyday use, nothing — both describe a curtain that coils above the opening. The real distinction is what the curtain is made of. Interlocking steel slats and a single formed steel sheet are different products with different standards behind them, and they fail differently.
My curtain is bent. Can that be repaired, or does the whole door go? It depends on how many slats are affected, whether matching slats are still available for that door, and whether the impact reached the barrel, shaft or brackets. Curtain damage alone is often repairable. A bent shaft usually is not.
How do I know if my rolling door is fire-rated? Look for a label or tag, a release mechanism, a fusible link, or a governor on the barrel — from where you are standing, not by climbing. If it has those, treat it as fire-rated and say so when you call.
The hand chain suddenly got very hard to pull. Is that serious? It is worth reporting promptly. Published guidance puts hand chain operating effort at no more than 35 pounds of force. A door that suddenly needs two people has changed, and the usual causes are counterbalance or binding — neither of which gets better on its own.
