Most shingle manufacturers only require a 4 nail pattern for installation. State Roofing Company uses a 6 nail pattern for all of our asphalt shingle installations. State Roofing Company ONLY hand nails our shingle roof systems and provides a backed manufacturer warranty of up to 130 mph wind rating.
130 MPH Wind Warranty typically requires 6 nails per shingle. State Roofing Company only hand nails shingle products to assure 6 nails placed in the nail line of each shingle. We do not use gun nails because of inconsistent practices. With a gun nail placement is inaccurate and will sometimes set the nail at an angle or cut through the shingle. State Roofing Company wants to assure you that your roof installation meets and exceeds the manufacturer installation requirements.
