Roll-up, sectional, high-speed or fire door?
A rolling-steel door — also called a roll-up or coiling door — is a curtain of narrow interlocking steel slats that winds around a drum inside a hood above the opening. It runs in steel guides on each side. That's different from a panel door on tracks, a fast fabric door, or a fire-rated rolling door, and each one has its own page.
| What you see | What it's called | Page |
|---|---|---|
| Narrow steel slats coiling up into a hood above the opening | Rolling-steel, roll-up or coiling door | This page |
| Corrugated sheet door at a storage unit | Sheet door (a lighter roll-up) | This page |
| Wide panels that ride up tracks and lie under the ceiling | Sectional overhead door | Commercial overhead door repair |
| Fabric curtain that opens and closes very fast | High-speed door | High-speed door repair |
| Rolling door with a fire label that closes on its own in an alarm | Rolling fire door | Rolling fire door repair |
Labels you may see: Cornell, Cookson, Overhead Door, Wayne Dalton, Raynor and Clopay all make rolling doors. Mention a brand only if you already know it. It's an example to help you describe the door, not a sign that a provider services that brand.

What's the door doing?
These rows help you describe it. They aren't a diagnosis.
| What you see | What a qualified tech may check | Why it matters | How to report it |
|---|---|---|---|
| Stuck partway open | Guides, slats, spring tension, operator limits | The building may not be secure | "Stuck three feet open at the loading door." |
| Won't roll up at all | Spring tension in the barrel, operator, chain hoist, a jam | Forcing it can damage the curtain | "It won't go up at all." |
| Bent or jammed slats | Individual slats and end locks | Bent slats bind in the guides | "A few slats are bent from a hit." |
| Guide bent after a hit | Side guides and wall mounting | The curtain can jump out of the guide | "The left guide is bent in." |
| Comes down fast or feels very heavy | Spring tension inside the barrel | The springs hold stored force | "It drops fast when we lower it." |
| Chain hoist jammed or slipping | Hoist, gears, chain | Manual doors rely on the hoist | "The pull chain won't turn." |
| Operator runs but the door doesn't | Operator, drive chain, brake, disconnect | Running a motor against a jam can damage it | "The motor runs, the door doesn't." |
| Bottom bar bent or torn | Bottom bar and seal | Weather, pests and security | "Bottom bar is bent." |
Stuck open or can't lock up the building?
Call and say "stuck open" first, then give the address and door number. Keep people clear of the opening and the curtain, and don't try to force the door down or wind it by hand. The springs inside the barrel hold stored force. Whether and when someone can come is confirmed by the provider on the call.
If you can't secure the building another way tonight, say that too.
If the door is stuck open, say so first.
Operators
Many rolling doors use a motor mounted beside the hood, and some use a hand chain hoist. Motorized doors have safety devices too. UL 325 is the product safety standard for door operators and their entrapment protection (UL 325 guide).
Operator wiring is electrical work. Suffolk County licenses master electricians, except in towns or villages with their own law (Suffolk Code Ch. 563). In Nassau, towns such as Hempstead, North Hempstead and Oyster Bay license electricians. Ask who holds the license if new wiring is involved.
What's covered, and what isn't
Covered: commercial rolling-steel, coiling and sheet doors on commercial buildings — warehouses, loading doors, fleet and auto bays, workshops and self-storage. Slats, end locks, guides, bottom bars, springs, hoods, chain hoists, operators and controls.
Not covered:
- Storefront security grilles and roll-down gates on shop fronts
- Home garage doors
- Truck and trailer roll-up doors
- Parts-only orders
A storefront gate or locksmith company is the right call for shop-front grilles. Fire-rated rolling doors go to rolling fire door repair.

What happens when you call
- You call (385) 325-7138. Say which door, where, and what it's doing.
- We route your call. It may be shared with an independent commercial dock-and-door repair company.
- That company confirms the details. Whether it can take the job, when, the scope and how it charges.
If you reach voicemail, leave the facility address, the door or dock number if known, what's wrong, and a callback number.
Example of what to say — not a script: "Our roll-up door at the loading door is stuck three feet open at our Farmingdale building, and I can give you the address."
See how Uptime works.
What helps (optional)
You can call without this. If you already know it:
- Motor, chain hoist, or push-up
- Roughly how wide the opening is
- Whether the door has a fire label (only if you can see it without getting close)
- When it happened
What affects the price of roll-up door repair?
We can't quote your roll-up 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.
| Price driver | Why it changes the price | Ask |
|---|---|---|
| Visit or diagnostic charge | Many companies charge to come out and look | "Is there a trip charge?" |
| Slats vs. whole curtain | A few slats can sometimes be swapped; a badly damaged curtain may not be worth it | "Can you replace just the damaged slats?" |
| Spring tension work | Adjusting or replacing barrel springs is specialized work | "Does the spring need adjusting or replacing?" |
| Guides | Straightening vs. replacing bent guides | "Can the guide be straightened?" |
| Operator | Repairing vs. replacing the motor and controls | "Repair the operator or replace it?" |
| Size, gauge, insulated slats | Bigger and insulated curtains cost more | "Does the size change the parts?" |
| Parts lead time | Some parts ship from the maker | "What happens while we wait?" |
| Access and height | Lifts and work height | "Do you need a lift?" |
Ask whether it's a call-out fee, a starting price, a fixed price for a set scope, an estimate or a final quote. For wider numbers, see commercial garage door cost.
Repair or replace?
When much of the curtain is damaged, the barrel or springs are worn out, or parts no longer fit, replacement may make more sense. See commercial garage door installation and replacement on Long Island.

Long Island rules for roll-up doors
- Permits come from the town, city or village, not the county. The Town of Islip says no permit is needed to replace a door that fits the existing opening with no header or stud changes (Town of Islip, June 16, 2025). Other towns and villages have their own rules.
- Electrical: see the operator section above.
- Fire-rated rolling doors have a yearly test and their own rules. See rolling fire door repair.
The provider and the issuing office confirm what applies to your door. The full table is on the Long Island dock and door repair page.

Questions about roll-up door repair
Why is my roll-up door stuck halfway?
Common causes a technician checks include a slat binding in a bent guide, spring tension in the barrel, the operator's limit settings, or a jammed hoist. Don't force it or try to wind it by hand. Call and say where it stopped.
Can a few bent slats be replaced?
Often, yes, if the rest of the curtain is in good shape and matching slats are available. Ask the provider whether a slat swap or a new curtain makes more sense and what each costs.
Is my roll-up door a fire door?
Rolling fire doors carry a fire label and are built to close on their own when a fire alarm or heat trips them. If you're not sure, say so on the call. Don't get close to a damaged door to look.
Do you fix storefront security gates?
No. Shop-front grilles and roll-down gates are a different trade. A storefront gate or locksmith company is the right call.
