Commercial Sectional Door Repair: what to note first

A forklift clipped the bottom panel while backing through the bay. The section is creased near an end stile, the lower roller rubs the track, and daylight now shows along one corner when the door closes.

Worth answering before the call

Does the door rise level on both sides? Is the door identified as part of a rated closure? Where during travel does the sound or hesitation occur?

How are replacement rollers chosen for a commercial door?

Roller diameter, stem length, bearing construction, track size and expected door use all shape the choice. The hinge position also matters because numbered end hinges place rollers at different offsets as the panels stack. The technician checks track condition and the mounting areas before fitting new rollers, so renewed hardware runs in a stable and correctly aligned guide.

What can staff prepare before the repair visit?

Clear vehicles, pallets and stored materials from both sides of the opening and arrange another traffic route. Have the door number, model information, control location and service record available if possible. Note where in the cycle the symptom occurs and whether there was an impact or recent change. Access to the electrical isolation point may also be needed.
