Gone are the days when tin roofs turn rusty and look shabby. Thanks to the advent of technology, a lot has changed in terms of tin roofs. The latest corrugated roofs are available in various colours. Most of these roofs are weather resistant and come in sheets 42 inches wide by 10 feet long. The best part about these corrugated tin roofs is that they can be installed by almost anyone.

Skill level:

Things you need

  • Measuring tape
  • Nails
  • Cutters to cut the tin sheets
  • Tin sheets
  • Ridge cap
  • Vapour barrier big enough to span across the entire roof
  • Toolbox
  • Screws

  1. 1

    Roll out the vapour barrier on your roof. The size of the vapour barrier should be enough to cover the roof. Ideally, the vapour barrier should be placed below the corrugated tin ensure that no moisture or dampness accumulates on the lower side of the tin. You can nail the barrier to the structure at equal intervals to ensure it stays at place. The vapour barrier should hang over the edges. After installation of the corrugated tin roof, you can trim off the extra part.

  2. 2

    Start from one corner of the roof and work your way across the rest of the roof. The corrugated tin roof should hang over the structure of the roof for drainage so that snow or water can fall off easily. Two inches of the tin sheets should hang over the edge of the structure.

  3. 3

    Ask someone to hold the tin until you align the corrugated tin sheets on the structure. Once the sheets are placed accurately, secure them in place by using screws placed at an equal interval of about 10 inches apart to create symmetry. The screws and tin roof should be the same colour.

  4. 4

    Once the first row of sheets are secured, position the second row of sheets. Place the sheets in such a manner that two inches overlap the first row.

  5. 5

    Once you have covered the entire stretch of the roof place the ridge caps. Ensure that the ridge caps overlap each other and are secured with same coloured screws.

Tips and warnings

  • Extra care needs to be taken while handling tin sheets to prevent injury by their sharp edges.
