Roll up shed doors are a convenient and space-saving way to gain access to a tool shed. They can be installed if a swing door cannot be installed or if sliding doors do not provide enough security. Over time, doors will become damaged through adverse weather conditions or everyday wear and tear. Shed door repair is a manageable project which can be completed by any DIY enthusiast.

Parts Identification

Before starting any repair or shed door replacement work, you will need to know the parts of the roll up door. These are the rollers, the track, the mounting brackets, and the hinges.

The rollers act like a guide for the opening and closing of the door while the track is the part of the construction that the rollers sit in. The track is attached to the shed door by mounting brackets. The rollers are attached to each side of the roll up shed door with hinges.


Most domestic roll up shed doors will be mounted on running tracks which are often made from metal. Before carrying out any repair work, clean the tracks and the rollers with a strong household cleaner or commercial degreaser to remove any dirt or grease.

If the tracks have been badly damaged, they will need to be replaced. This will require the hinges to be removed. Installing new tracks requires nothing more than removing all of the securing screws and swapping the old tracks for new ones before putting the old screws back into place.


If the hinges have become bent over time, this will prevent the rollers from functioning properly. To remove the hinges, use a clamp to hold the door open and keep the door supported in its open position while you remove the bolts and hinges. If the door isn’t supported, it could easily bend. A few upright props will also prevent the door from shifting while the hinges are either tapped straight or replaced.


Rollers can become worn out over time and will need to be removed and replaced. To remove the rollers for roll up shed doors, you will need to remove the hinges first. Once the hinge and the rollers have been removed, you will need to ensure that the replacement is the exact replica. These can be purchased from most hardware stores. If you know the model and the serial number of your roll up shed door, it should help when trying to find an exact match.


If the mounting brackets for a roll up shed door become loose, you will need to tighten them. To tighten the brackets, prop open the shed door with a clamp, then tighten them with a screwdriver.


You will have to replace your shed doors if they have become damaged or dented. To replace the roll up doors, hold them open and prop them up while you remove the hinges and mounting brackets. Once you've completely removed the doors, you can install the replacements. Start by securing the rollers into the tracks before securing the hinges and tightening the mounting brackets.

Because roll up shed doors are difficult to maneuver, use the assistance of at least two other able-bodied individuals to help take the weight and prevent excessive movement.


Once you've completed any door repairs, you will need to lubricate the individual parts. Use an oil spray and apply it directly to all moving parts and guides of the doors.
