Were rafter vents installed in the cathedral ceiling before the insulation was installed?

I have several cathedral ceilings & all have/will have a ridge vents
Its pretty standard to do so
Keeping the roof/roof deck cool will extend the lifetime of the roof

Planning on directly letting in or out environments????? Then, by all means, Vent it.

It has been my experience that this is NOT standard practice!


Here is sumpin' to read...........

That write-up is 10 years old
But it does point out:

Many asphalt shingle manufacturers do not currently warrant their shingles on unvented roofs.​
There are good & bad ridge vents
Proper installation is also key

Also doesn't state where you are located
Up here in New England cooling isn't needed to an extreme
But proper ventialtion to avoid moisture is
And extending the shingle life

When I retrofitted soffits & a ridge vent into my front roof I also retrofitted rafter vents. When I pushed the final rafter vent into place there was a rush of cool air coming up

Even with proper venting & insulation my sunroom roof had ice dams this past winter. We had storm after storm & it faces South, so sun was melting snow & it was refreezing. No leaks - thank you ice & water shield
