What is typically the best method for fastening asphalt shingles?

Nails are typically the best method for fastening asphalt shingles because they provide the necessary holding power and durability required to secure shingles against wind uplift and other environmental factors. Properly installed nails penetrate through the shingle and into the underlying decking, ensuring a strong connection that withstands the elements.

Using nails allows for slight adjustments during the installation process, which can help achieve a better alignment and fit for each shingle. Commonly, roofing nails with a wide plastic or metal head are used to help distribute the weight and reduce the chances of damage to the shingles themselves. Additionally, the use of nails is commonly recommended in roofing standards and building codes, emphasizing their effectiveness and reliability over other methods.

While staples and glue may be options for fastening materials in other contexts, they do not provide the same level of security and resistance to wind and moisture that nails do when it comes to asphalt shingles. Heavy tape, while versatile, is not appropriate for this application as it cannot provide the structural integrity and weather resistance needed for roofing materials.
