Gravity roof vent help - texas coast 120mph exp C
Hello to all,
New user here.
I currently have a contractor, who ordered 80 mph roof vents (gravity) on my 120 mph exposure C building.
The contractor states there are no gravity roof vents up to 44"x44" roof curb size on the market.
I personally found a couple "penthouse styles" that could work in a pinch from Miami-Dade County (NPJ), but a more conventional design that meets 120 mph and up to 70 psf is desireable.
Anyone know of other "high wind" manufacturers?
