I live in Canada and I just had my roof done on my house.
I recently went in my attic and found out that some part of the roof is missing plywood 🙁
In the following picture, there is no nails visible. Which means the shingles behind are not nailed in???
When the contractor did the estimate, he did notice places where the plywood was rotten and told me he would need to replace them. Well clearly he didn't. He just cut away the rotten plywood 🙁
Is that normal practice. Should I be worried or is this ok?
UPDATE:
So I did get in contact with the contractor. Apparently, this is where the old air vents were.
He tells me that there is a metal sheet between the shingles and the membrane.
He told me that the membrane that we can see in the pictures is to protect against humidity.
Is that a good practice when removing old air vents?
UPDATE 2:
Thanks for all the information, really appreciate the help.
Just to clarify, because I might have not been clear, the old vents were removed and new vents installed. I was made aware of that in the contract and the new vents are more powerfully, so for every 2 old vents removed, 1 new vent was installed. I believe this is ok.
I went back in the attic and took more photos
As for the proper amount of nailing, its really hard to tell. I'm no expert and I cant seem to see any kind of patterns with the nails. Here is a photo were I could sort of see a pattern.
UPDATE 3:
So first, I contacted the manufacturer of the shingles and explained the situation. They told me that the shingles installed over the metal sheet are NOT properly installed and that the shingles would NOT be covered under the High Wind Resistance Limited Warranty. They did suggest that I contact an inspector. The contractor that did the job was also certified with that manufacturer. So they will be looking into that.
I wrote to the RBQ, which is my province Code regulator, but did not get a reply yet.
I'm also trying to get in contact with my municipal urban department which, I have been told, can probably help me and tell me if this respects the code or not.
I was able to talk to another contractor in my region and he told me this is ok and that I shouldn't worry about it. We did have very strong wind recently and my roof did resist.
Still not sure what to make all of this.
Thanks for all the comments, really helps.

As a R.R.C. and roofer for over 25 years, this doesn't surprise me. Anyone with a pickup truck and a ladder calls himself a roofer. This is wrong, if they eliminated vents they should have replaced the sheathing. An opening up to 4"x4" can be covered with metal, but anything bigger requires re-sheathing to eliminate a fall hazard. Also the nail pattern should be evident. Thinking you need to call an attorney. If he did this he isn't reputable so it stands to reason he won't back up his work. Always check references and reviews of your contractor. Check with the BBB to see if there are complaints. Look at their work!! Drive by a couple of their jobs, talk to homeowners if possible. Not only end result is important but being done without damaging your property and in a timely manner is just as important.
