What length and type of nail should I use with the Hip Ridge Vent? Can a nail gun be used?
As long as the nail fully penetrates the roof deck any variety of standard roofing nail will work. A nail gun can be used as long as the installer checks the nail gun pressure to ensure the nails are not over-driven or under-driven. Over-driven nails could dimple or distort the cap shingles on the vent. Under-driven nails could contribute to the ridge vent backing out of the deck and lifting. This could lead to blow-off and/or wind/weather infiltration under the lifted vent. Additionally, under-driven nails could cause the cap shingles to blow off.
