What is the proper method for nail placement when roofing?

• A. Nail at an angle
• B. Nail straight and flush
• C. Nail diagonally
• D. Nail anywhere

Answer: (B)

Nail placement in roofing hinges on driving fasteners straight into the surface so the head sits flush against the shingle. When the nail goes in perpendicular to the roof, it grips securely and the sealing area around the nail remains intact, helping to keep wind from lifting the shingle and water from seeping in. If you drive nails at an angle, the head can sit unevenly, create gaps, or even pull the shingle away under wind loads. Angled or diagonal nailing can also risk splitting the material or missing the proper nailing zone. Nailing haphazardly or anywhere else won’t secure the shingles effectively or maintain a proper weather seal. Keeping nails straight and flush ensures a tight, durable connection and better protection against leaks.
