- Remove any existing fascia boards Remove the fascia boards and the old felt if you’re re-felting.
- 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.
- 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.
- 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.
Caersws
Caersws is a village as well as area on the River Severn, in the Welsh county of Powys (Montgomeryshire) 5 miles (8 kilometres) west of Newtown, and also halfway in between Aberystwyth and also Shrewsbury. It has a station on the Cambrian Line from Aberystwyth to Shrewsbury. At the 2001 census it had a population of 1,526, increasing slightly to 1,586 at the 2011 Demographics. In modern-day Welsh, Caersws literally indicates "Ft Kiss", although sws probably derives from some other resource. It has actually been said that the site may maintain a Roman-era devotion to Zeus or protect the name of a conjectured British queen Swswen.
