How many fasteners are required for installing 36-inch asphalt shingles?

For installing 36-inch asphalt shingles, four fasteners are typically required for each shingle. This number ensures secure attachment to prevent the shingles from being lifted or damaged by wind and weather conditions. Proper installation is critical in roofing to maintain the integrity of the roof and to comply with manufacturer specifications as well as applicable building codes.

Each fastener helps create a strong bond between the shingle and the roof deck, allowing the shingles to effectively shed water and providing durability against the elements. This standard of using four fasteners is a widely accepted practice within the industry, aligning with best practices to ensure long-term performance and reduce the likelihood of issues such as leaks or blown-off shingles.
