Are shingles on a plastic ridge vent only for cosmetic appearance? (About 8ft of shingles blew off the ridge vent; vent itself is fine.) If I don't use shingles at all and just cover the plastic with some ultraviolet resistant covering (which would be easier for me to do vs. nailing in shingles), would that probably last 5-7 years or so in the sun in the NYC area? For the UV-resistant covering, I was thinking maybe Gorilla tape,

Gorilla tape, as good as it is, won't last one summer. I have a
plastic garbage can lid with a 4" crack patched with gorilla tape and
it's lasted for a year, but it's on the shady side of the house, n ot on
the roof.

or even roof cement spread over the ridge vent. The ridge vent is GAF Cobra roll, and the data sheet for that says the plastic contains Carbon black, which is good for UV resistance, but I want to cover that ridge vent plastic also, to provide more UV shading. Thanks.

What's so hard about nailing on cap shingles? Sounds a lot easier to me than
trying to kludge something half-assed together that's going to be an obvious
kludge job. You can just cut regular shingles
or some manufacturers offer cap shingles that don't need to be cut. Find ones
that match the roof.

Heck, it's trim. It can contrast with the rest of the roof and still
look good. OR, I patched my roof a year ago near the roof ridge and I
kicked myself that I didn't save the brand and color of the original
roof, so I could get matching shingles. (And I even let a few left-over
shingles get ruined and threw them away. Kicking myself again.)

So I let roofer get whatever he thought was good (and he only had two
possible shades of tan) and you know what? There is too much light** in
the sky and I can never tell if it matches or not. **Except at night,
and I can't tell then either. Maybe if I had a one-story house it
would be visible, even noticeable. But I don't think so. You can't see
the roof when you get close to the house.

That roll stuff is just flimsy material and it's intended to be
covered with shingles for it to last and to keep water out. I'm sure there are plenty
of youtube videos showing how to do it.




I looked that stuff up. It is not what we call ridge vent.
The stuff we use is mushroom shaped aluminum with holes up under the
dome, The shingles go up to the cut in the sheathing and this goes on
top.
