How many nails or staples are required per shingle for asphalt shingles installed as siding?

Asphalt shingles installed as siding typically require six nails or staples per shingle. This standard is recommended to ensure that the shingles are adequately secured against wind and other environmental conditions. The number of fasteners is critical for the durability and integrity of the siding, as it helps prevent the shingles from being dislodged.

Using six fasteners allows for a balanced distribution of force across the shingle, reducing the risk of damage and increasing the longevity of the installation. Adequate fastening is essential not just for structural stability, but also for maintaining the aesthetic appeal and functionality of the siding over time. Proper adherence to installation guidelines, including the number of fasteners, is crucial for ensuring that the asphalt shingles perform effectively throughout their expected lifespan.
