How to Set Up a Metal Shed

Choose a location for your metal shed, ideally on a flat, square piece of land. Sloping areas need supports built beneath them -- before the shed can be assembled. Choose an area over soil with adequate drainage, to avoid flooding.

Lay down a waterproof membrane over the leveled land where you'll assemble your shed. The membrane should be in one piece and at least 6 mils thick to prevent moisture from seeping in. Use your kit to ensure a square and level foundation.

Set out the framing for the shed. It may come with the shed, or may be sold as a separate kit. Double check that all pre-drilled holes line up correctly to accept the side panels.

Hold up and attach side panels per assembly instructions, using any pre-drilled holes and anchors accordingly. Holding up the sides typically takes two to three people. Repeat this step with all four sides.

Attach the corner columns, as directed, as you erect each side panel. Attach using screws or the provided hardware -- starting at the bottom of the shed, then working your way up each column.

Install any center bands to stabilize the side and front panels.

Attach the roof framing per instructions, typically beginning with the center and then side-column fittings, as well as those for the door.

Lay the roof piece or pieces onto the frame, and attach using the designated holes with screws or provided hardware.

Attach the front door per instructions -- ensuring it sits level by using a carpenter's level -- and test the door for unobstructed opening and closing.

Line the inside joints with silicone sealant for weather-proofing. Let the sealant dry completely, between 24 and 48 hours, depending on humidity and temperature. Refer to product instructions for specific curing times.

Anchor your shed per assembly instructions using weights specified for your kit. Tying sandbags or cement blocks to its four corners works temporarily.
