Shingles without support on ridge

I recently had a new roof put on and it looks like the roofer cut too much of the plywood for the ridge vent to go. They then filled in the hole with shingles and no support on the bottom. Is this work done correctly and could it cause leaks? This continues for most of the roof line. The contractor stated that it will not cause a problem and is ok.


That is normal. The shingles you are seeing are “cap shingles”.


So there doesn’t need to be any plywood, or support underneath the cap shingles?

No. (Stupid character minimum)……
