I live in Canada and I just had my roof done on my house.
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?
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?
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.
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.
