Improper shingle nailing
One of the most common defects with asphalt shingles is improper nailing. IKO and other manufacturers of asphalt shingles give specific instructions on how to fasten shingles, and they’re all pretty much the same. Unfortunately, some roofers don’t seem to pay a lot of attention to these instructions. That is why we want to highlight the two most common nailing defects with shingles: overdriven nails and improperly located nails.
Overdriven nails
Many roofers use pneumatic nail guns to nail down the shingles. When the pressure is set too high, the nails simply get driven into the shingles too far. When the nails are overdriven, the heads of the nails punch right through the mat of the shingle. This voids the shingle manufacturer’s warranty and greatly increases the potential for shingles to come loose and be blown off, possibly in full shingle sheets.
Improperly located nails
The other common nailing defect is improperly located nails. It is very problematic to have nails located too high on the shingle. The correct nail must be applied 2,5 cm above the cut-out and 2,5 cm from each edge. For the Cambridge shingle nails must be applied into the nailing zone. When properly placed, the nail will actually catch the top edge of the shingle below it. When the nails are located too high on the shingle, they never catch the shingle below. With this application mistake shingles are less wind resistant and easily can blow off from the roof.
Take a look at the examples of improperly located nails in this gallery.
Remember: Only properly driven and applied roofing nails are utilized as a preferred fixing system for asphalt roof shingles!
Bitumen roof shingles may be one of the simplest roofing materials to install, but nevertheless they also require specialized and exact rules on how to be fastened. It is important to apply roofing nails in the right quantity and location to securely lock a shingle into its place. Accurate nailing affects the performance of roofing shingles and it is also required by the International Building Code.
