  1. 1

    Remove any shingles or other roofing material on your outbuilding, down to the plywood of the roof. Make sure there are no protruding nails, screws or anything that will tear or wrinkle the roofing felt.

  2. 2

    Measure the length of your outbuilding's roof from the gable to the edge or to the gutters. Cut a length of roofing felt to fit and lay it on the edge of the roof, beginning on the left side. Felt works as a sound barrier and helps keep insects from getting through the roof. Attach the roofing felt to the roof with roofing nails and a nail gun or staples and a staple gun. Overlap each successive section of roofing felt until the roof is covered.

  3. 3

    Mark a chalk line on top of the felt, indicating the width of each tin sheet plus a 1-inch overlap. This will help you keep the sheets of tin straight as you install them on the roof.

  4. 4

    Cut sheets of tin in lengths that fit your roof from the gable to the gutter as in Step 2. Position your tin sheets on the roof of your outbuilding using the chalk line as a guide. Attach the tin through the felt and into the roof with roofing nails and a hammer or nail gun. Place one nail every 6 inches down the length of the roof and at the gable and the gutter ends. Cover the roof with tin sheets.

  5. 5

    Add roofing cement to the seams of your tin to further protect your roof from moisture, animals and insects.

Tips and warnings

  • Apply specially designed tin clips around the perimeter of the roof to further hold the tin in place.
  • Wear gloves when handling tin.
