To lay these shingles at pitches greater than 15 degrees:

• Lay the felt with at least a 75mm lap on the joints.
• Fix the felt to the board using 3mm to 3.5mm diameter barbed hot dipped galvanized roofing nails with a minimum 10mm head.
• Nails must be long enough to penetrate a minimum of 20mm into the solid wood deck or just through the plywood deck
• Staples are not recommended
• Raised nails can result in shingle distortion and may prevent sealing
• Drive the nails until they are flush with the surface but do not overdrive nails
• Do not nail into the sealing strip as the nails may prevent proper sealing
• Do not drive nails at an angle

To lay these shingles at pitches between 8 degrees and 15 degrees:

• Use a suitable underlay for the shingles such as either a quality shed felt, or better still a quality 3B Underlay felt (available separately).
• Lay the felt with at least a 100mm lap on the joints.
• Fix the felt to the board using 3mm to 3.5mm diameter barbed hot dipped galvanized roofing nails with a minimum 10mm head or glue the felt down using bitumen adhesive.
• Nails must be long enough to penetrate a minimum of 20mm into the solid wood deck or just through the plywood deck
• Staples are not recommended
• Raised nails can result in shingle distortion and may prevent sealing
• Drive the nails until they are flush with the surface but do not overdrive nails
• Do not nail into the sealing strip as the nails may prevent proper sealing
• Do not drive nails at an angle

Ridges / Hips:

• These are made from the strips of shingles, by cutting the strips into the individual tile shaped "tabs" and then overlaying them over each other along the ridges or hips.
• This simple method reduces wastage as you are able to use your offcuts rather than having to throw them away!
• Alternatively, you can make an allowance for the hips / ridge when estimating your requirements by allowing for 2.4 strips of shingles per linear metre of ridge / hip.
