What is Roll Vent®? Roll Vent is the first ridge vent on a roll and was created by Benjamin Obdyke in 1987. Aren’t all ridge vents the same – Why should I use Roll Vent? Roll Vent has some unique qualities over the competition such as the “gull wing” design that prevents shingles from bending over the sides. Roll Vent also has a see-through hinge which makes it easier to center over the ridge. Finally, the visible nail line helps assist with the alignment of shingles. What is the net free area (NFA) of Roll Vent? 18 square inches per linear foot—As much as 50% more NFA than other ridge vents. Can Roll Vent be used without a soffit system? No. A balanced system is necessary to achieve proper ventilation. The use of a ridge vent without equal or greater soffit vent could cause the ridge vent to act as an intake rather than an exhaust vent. Can Roll Vent be installed with a nail gun? It is not recommended as nail guns can only use a maximum nail length of 1 ¾ inch--that may not be sufficient to properly fasten Roll Vent to the roof deck in order to prevent blow-offs. Does Roll Vent need separate end plugs? No. End plugs are not necessary if ridge cap shingles are lapped over end of product and down onto the ridge. Optionally, Roll Vent can be installed right to the gable ends using an integral end plug that involves cutting the matrix and folding the fabric over the matrix. See the Roll Vent installation instructions. Can Roll Vent be used with gable vents? No. Never combine ridge vents with gable vents. Air will move from the gable to the ridge and the remainder of the attic will not be effectively vented; therefore leaving hot, moist air to cling to the underside of the sheathing. This could create ice damming. When installing a ridge vent, be sure to also install soffit vents and block off the interior of the gables; using them for aesthetic value only. Is there a problem if Roll Vent is installed with the fabric side facing up? Yes. The warranty is VOID. Will Roll Vent clog? No. Roll Vent has been tested using fiberglass insulation in both dry and wet conditions. Results show less than 3% of the total exposed Roll Vent showed any adherence. What is the difference between Rapid Ridge® and Roll Vent? Rapid Ridge has a lower profile for nail gun-able application; Roll Vent cannot be installed with a nail gun. Rapid Ridge has a net free area of 12.5 inches per linear foot, while Roll Vent has maximum ventilation with 18 inches per linear foot of net free area. Does Roll Vent come with nails? Yes. Each roll of Roll Vent comes with 2 ½ inch nails. |
