The placement of each roofing nail will eventually determine the durability of roof shingles. Shingles are designed to be nailed on a specific location and the nail must be driven to a certain depth. Usually the nailing location is situated ± 25 mm above the cut-out and 25 mm from the end. However, on our laminated Cambridge shingles the position of the nails is between the two white lines which we also call the nailing lane or zone.

Every roofing nail must penetrate the wooden deck with a minimum of 19 mm. If this position or depth of the nail is off by even a little, water might penetrate inside or the shingle may be blown off in high winds. IKO’s manufacturing warranty coverage might also be voided if the inspection finds that the reason of the problem was incorrect nail placement.
