    These Mongoose and Cobra brand roof vent systems are available here that use asphalt shingles to hide the vent. HOWEVER, the shingles are held in place with 2 inch roofing nails placed via a gun. The wind can get under the shingles, and the small nail head, can not prevent the shingles from being ripped off under 120MPH winds, which happen enough, that I've had two wind events in less then 10 years with these shingles being removed from the plastic vent. And when that does, it is open to the weather, and I had rain damage.
    Nope not a fan of these type of roof vents. They are not wind resistant enough.
    My fix was to put 1/2 sq bar along each edge along the length of the vent to keep the shingle edge from being able to get caught by the wind.
    I screwed that down every two feet or so with long construction screws, with holes in that square bar. I'm getting too old to get up on a 30ft in the air on the roof. So far this fix has worked.
