Your roof is a valuable investment so you should only entrust it with an experienced roofing contractor. Though required by the International Building Code, improper shingle nailing is one of the most common issues with asphalt shingles.
Today, we’ll share with you the best practices on asphalt shingle nailing.
Right Roofing Nails
Roofing nails are used to secure shingles, install the roofing underlayment and to install roof tiles and sheet metal. There are various kinds of roofing nails in different sizes, made from different materials.
A roofing nail should not have a nominal shank diameter of less than 9.5. It should have a barbed shank for the heat to eliminate nail pops, blow-offs and roof leaks. Nails with larger heads and heavier shank gauge have greater holding power. Moreover, nails must be corrosion-resistant.
Nails should be long enough to pierce the roofing material and go 19mm into the decking. Consider the number of layers of shingles, shingle thickness, underlayment and flashing to determine the nail length.
Proper fastening is essential to the performance of a roof. This job is best left to professionals to ensure efficient installation. Whether you’re looking for a high-quality roof or siding replacement, you can count on Turner Home Improvement Contractor, LLC.
Make sure to use the proper kind and recommended number of nails per shingle. Position nails according to the shingle specifications. Shingles should be properly aligned before nailing to avoid exposing the nails in the underlayment below.
Nails must be driven straight and flat with the surface. Nailheads shouldn’t be used to break the shingle surface. Roofing nails shouldn’t be driven into the knotholes or cracks in the decking. Repair improper nailing as soon as possible and always nail shingles from one side to the other to keep them flat on the roof.
