Hi Any opinions on the plastic rolled ridge venting that is sold in your typical Menards/HD type stores? It just seems chintzy to me and I've been on a few roofs were it appeared to be very clogged with leaves and other debris. If I use it should I tack down some metal screen to double-check the thin strip of plastic mesh on the venting that supposedly keeps the bugs out? Second floor is converted attic so traditional square vents are not an option. Previous owner insulated with the 1 inch gap under the sheathing to allow for air flow, so ridge vent should work properly. Any comments greatly appreciated.
