Asphalt shingles are being installed on a roof with 5/8 inch sheathing, the nails shall:

• A. penetrate completely through sheathing
• B. be flush with the surface
• C. not penetrate the sheathing
• D. anchor only to the framing

Answer: (A)

When installing asphalt shingles on a roof with 5/8 inch sheathing, it is important for the nails to penetrate completely through the sheathing. This ensures that the shingles are properly secured to the underlying structure, which is critical for the roof's integrity and durability. By penetrating the sheathing, nails can anchor securely into the framing underneath, providing better resistance to wind uplift and securing the shingles against potential weather damage. Penetration through the sheathing also allows for a tighter hold, preventing the shingles from lifting or being displaced over time. Additionally, proper nailing practices contribute to effective waterproofing and overall performance of the roofing system. The other approaches, such as being flush with the surface or not penetrating the sheathing at all, do not provide sufficient anchorage and could result in roofing failures. Anchoring only to the framing without nail penetration through the sheathing may also not provide the necessary security for the shingles.
