A metal roof can help your shed and the items it stores stand up to the elements as long as possible. The process is the same as it would be on a larger structure, but it should be a little easier, provided your shed is a modest size.

Step 1 - Remove the Old Roof

Use a ladder to reach the top of the shed and begin removing the old material. Make sure the ladder is secure before climbing on top.

Use a claw hammer or roofing hammer to rip up the roofing material. A large garbage can or trash bin will be helpful to collect debris as you work. This will make cleaning up after the job easier.

Protective clothing, gloves, and eyewear should be worn at all times to reduce the possibility of injury.

Step 2 - Install Underlayment

Install the underlayment material (i.e. tar paper) over the top of the plywood panels. If the roof is exposed with the rafters pointing upward, purchase 1/4 to 1/2 inch thick plywood and nail it to the roof, completely covering it.

Secure the underlayment material to the plywood using roofing nails and the hammer. If you have a roof nailer, this will make securing the underlayment faster and easier.

Step 3 - Install Drip Edge

Once the underlayment has been nailed into place onto the plywood sheets, install a drip edge to the to catch water and remove it from the roof.

Step 4 - Install the Metal Roofing Panels

Set the panels in place piece by piece before securing them to the roof. The panels should interlock, making them easy to connect.

Ideally, you should use hot-dipped galvanized nails as fasteners to affix the panels. The hot-dipped galvanized nails are perfect for outdoor use as they resist rusting and will not be easy for water to penetrate.

Any overhang material should be trimmed off the roof using tin snips or shears.
