Finishing a metal shed roof should be done on an outdoor storage shed to ensure the shed will last and will stand up to the elements. The finishing process comes after installation of the metal shed roof and securing it to the roof of the shed. The process, tools and materials needed to accomplish this task are outlined below. The materials needed to finish your metal shed roof can be purchased at a home improvement center or specialty store that sells roofing materials.

Step 1 - Remove the Old Roof

  • Use a ladder to reach the top of the shed in order to begin removing the old roof from the shed.
  • Make sure that the ladder is secure before climbing on top.
  • Use a claw hammer or roofing hammer to rip up the roofing material to remove it. A large garbage can or trash bin will be helpful for you to throw debris into as you work. This will make cleaning up after the job easier.
  • Work carefully while removing the material. Protective clothing, gloves and eyewear should be worn at all times to reduce the possibility of injury while you work.

Step 2 - Install Underlayment

  • Install the underlayment material (i.e. tar paper) to the roof of the shed. The underlayment will be placed over the top of the plywood panels that are in place. 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 roof in order to catch water and remove it from the roof.
  • Follow the installation instructions accompanying the drip edge for proper installation.

Step 4 - Install the Metal Roofing Panels

  • Begin setting the panels into place in order to secure them to the roof.
  • The metal roofing panels should interlock, making them easy to connect and place on the roof.
  • You will need to use hot-dipped galvanized nails as fasteners in order to secure 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.
  • Work methodically as you attach the metal panels to the shed’s roof. Any overhang material should be trimmed off the roof using tin snips or shears.
