It's okay to a add ridge vent to your architectural shingles, but I do
hope that you have the warranty from your contractors if something were
to happen. It is fine, actually. It would look more appealing if you
installed one. Next time, however, ask your contractor about your
warranty first, just so you can be sure to be able to get your money
back before you pursue what it is youâ€™re planning.
Yes, and there's no other venting that's better. Just make sure you have soffit intake-vents to start with and that you close-off any gable or other roof exhausting vents or the ridge vent won't do much of anything.
