How to felt a shed roof

A shed for your gardening supplies and various tools is great. The items are easy to find and out of the way. However, opening the shed and finding that all of the items are wet is not only irritating, it can prove costly as water can damage or ruin many items very quickly.

Here we provide instructions on how to felt your roof; a link to a YouTube video demonstration; and an innovative alternative to shed felt.

Instructions: Felting Your Shed Roof

Fortunately protecting the items in you shed is easy. You don’t need any specialised tools or a lot of time. The entire project can be completed quickly; a small shed will most likely be completed in about an hour. 

The project can be easily done by yourself, but obviously will be easier and faster if you have a helper.

Tools and materials

  • A hammer
  • Step ladder
  • A level, which can double as a straight edge
  • Craft knife
  • A tape measure
  • Roofing tacks (Don’t use other types of nails or tacks as they will often allow water to seep through.)
  • Barge boards (Be sure that they are at least the same width as the shed’s eaves, a few cm wider is ok as well.)
  • Roofing felt

To deterime the amount of roofing felt you need, measure the roof to determine the square meters and add about 25%.

Installing your roof felt

Once you have your tools and materials ready, the rest is simple.

  1. Cut the roofing felt into the lengths you need to cover the roof from front to back. Cut the felt about 10cm longer than the length of the shed. 
  2. Place the first piece at one edge and tack the front and back. You want about a 40mm overlap at the eaves.
  3. Work your way up the panel to the apex of your shed’s roof. Be sure that adjacent pieces overlap by about 20cm. This prevents water from seeping between the two pieces of felt. If you can cover each panel with a single piece of felt, you still want to have a piece that goes across the apex and overlaps each side. 
  4. Once you have all of the pieces in place, it is time to tack them down. Space the tacks about 150mm apart along the edges and across any areas where the felt overlaps. 
  5. Fold the felt along the edges of the shed and tack them in place. You want to eliminate any areas where water can seep in. 
  6. For the apex piece, you will want to cut a slit and fold the piece under and secure with tacks. 
  7. Take the barge boards and cover the edges on all sides. You should use standard nails for this part of the project. If you barge boards are slightly wider than the eaves, make sure they are flush along the upper edge. 
  8. Now take your craft knife and carefully cut away any excess felt. You want your felt to be nice and tight. Excess felt not only spoils the look of the shed but can eventually cause damage to the felt’s integrity.

That’s it. All that is left is to put away your tools, secure in the knowledge that the items in your shed are protected from all of the elements.
