Felting the Roof

Some sheds are supplied with a roll of roof felt, but you will still need to cut it to size with a sharp knife and a straight edge tool. If the felt is not supplied, WONKEE DONKEE recommends using a Green Mineral Roofing Felt, available from your local builders' merchant.

WONKEE DONKEE recommends a traditional Green Mineral Shed Felt.

• Nailed with galvanised clout nails
• Bonded with roofing felt adhesive
• 5-year life expectancy
• Single layer waterproofing
• Light yet durable
• Fibre reinforced
• Fine green mineral finish

Unroll the roofing felt, measure and cut three pieces - one for each roof panel and a third strip to be laid over the apex [the top or highest point] of the roof, to prevent water seeping in.

The pieces covering the roof panels run the full length of the shed with a 50mm overhang at either end.

Lay the first piece over the roof panel with a 50mm overhang at the eave [part of the roof that overhangs the walls of the shed], repeat on the other side.

Tack along the top edges with 13mm roofing felt nails, 300mm apart.

The third piece covering the apex will be the same length and overlap by 75mm on each roof panel. Place over the top of the roof and felt nail along each edge at 100mm intervals, on both sides.

Fold the corners and nail down. Hammer the roof fascia into position over the front and back gable ends using 40mm galvanised nails.
