I’m ripping the roof off of our summer camp and putting a new roof on. The roof deck is constructed of 3/4" T&G pine boards. I’m about to order materials and am curious what length roofing nails I should use. I’m installing Grace Ice and Water Shield over the entire deck and then GAF Timberline HD shingles. The deck boards are visible underneath the soffits so I likely need shorter ones for that area so they don’t penetrate through. Also, I thought about using ring shank nails but it looks like Grace recomends smooth shank for better sealing. Any info on proper length roofing nails to get would be appreciated.
