When calculating the amount of Net Free Area needed using Hip Ridge Vent how do I account for the staggered slot perhaps reducing the vent’s Net Free Area?
If the slot is properly cut in width and length according the installation instructions you will not reduce the vent’s Net Free Area. The only case in which a staggered slot can reduce the Net Free Area is when the remainder slot to be cut at the junction of the hip ridge and peak ridge cannot be done due to the necessary 12″ of solid deck from the peak ridge to the hip ridge slot and the 8″ of solid deck from any joint overlaps.
