Try to put your shed in open space, away from trees, bushes and other buildings. This will help to protect it from falling branches and sap. It will also mean that you can access all sides of the shed for repair and maintenance purposes. Make sure you take a look at garden shed planning rules before you pick a final spot for your shed.

1. Remove any existing fascia boards Remove the fascia boards and the old felt if you’re re-felting.
2. Measure the shed roof Measure the roof, taking into account that you should leave around 50mm for overlaps at the eaves and 75mm at the gable ends. You’ll probably need 3 pieces of felt, but some smaller sheds only need 2.
3. Apply felt to the roof Once you’ve cut the felt to size, apply the each piece to the roof, pulling it tight. Then nail along the length of the roof at 100mm intervals. For nails at the bottom edge, they can be wider – around 300mm. If you’re adding a piece of felt in the middle of the shed along the apex, fix it using adhesive, then nail it at the lower edge at 50mm intervals.
4. Tidy up the overhangs Fold down the felt at each overhang and nail it securely. Cut a slit in the overhang at the apex using a pen knife, then fold that down and nail at 100mm intervals along the gable. If you like, you can add fascia boards to keep the shed looking neat. Use wood nails to secure them and then trim away any excess felt.
