New roof - corners are lifted

Hi all, I'm wondering if you can help. I just got a new roof put on by a reputable company in my area. The thing is that the corners of the roof (both front corners and one back corner) are lifted up. I believe this may have been there before they replaced the roof. However, when I showed them, they said that it was better not to fix this. I don't remember what his explanation is but I showed a couple of people who have actually done 3 roofs themselves and built their own sheds and decks and they said it's wrong and that it will cause major problems. The thing is....I believe it was there before and they said that the the boards weren't rotten or anything. I have a call in with the company tomorrow.

The other thing is that it's lifted right over the gutter too on the pic with the branch in front of it. They said this was necessary because - something about the gutter.

I'd really like your feedback. I thought they would have fixed it even it was there but would love your thought.
Thanks in advance!

I'm not a pro, but I know cold roofing materials are often not flat and will flatten out when the hot sun does its thing. So long as they laid a double shingle layer over watershield barrier, I think it should be fine.

Thanks for your reply! The project manager offered to me that it's been in the sun for 3 days so he didn't think the cold/hot was an issue.

I'm not sure if they did a double shingle layer. Is that standard? I thought a single layer layer was standard? And I hope they put down a water shield barrier. Uh oh.

We live in Western NC.

double layer only on the first course? Are there two courses? Sorry, roofing is new for me.

Did they remove the existing shingles or did they nail the new ones over the old?
The first coarse of shingles either needs a double layer or ice shield so water can't get in between the tabs.

They definitely removed the old shingles first.

And thanks for clarifying that.

I'm a painter not a roofer although I have done diy roofing.
Something is preventing those shingles from laying flat. It would be nice to hear what the roofing rep says when he comes out.

Gotcha! My partner met the guy over there and he said the guy said that it's scalloping due to being old but nothing was rotten and they were in good shape so they kept them as is. My partner said the plywood sheets are sagging between the roof trusses. Does that make sense?

If under supported or too thin the plywood can sag between joists' If that is caused by the plywood I'd think it's more likely that the edge of the plywood is no longer secured to that joists. I don't think that would explain the gutter pic.

They actually said that the gutter pic was correct and had to do with the runoff. Doesn't make a lot of sense but not sure what to think.

Your point, "If under supported or too thin the plywood can sag between joists' If that is caused by the plywood I'd think it's more likely that the edge of the plywood is no longer secured to that joists."

Is a good one. It just doesn't seem right that they left them like they are. Is that what you're saying? That there is an underlying problem that's causing them to curl?

Hard to tell just from a pic. Hopefully the roofing rep will get up on the roof to investigate further.

I think they already did. Two guys met my partner over there. They were on the roof when he got there. And the one guy called me afterwards to explain but I had to go so rescheduled call for later. Then, my partner explained and drew me a picture so I could understand.

It seems like they did check it out. It's so strange that they have a crew do the project and another project foreman but I talk to two people that weren't even on the project. It seems common but strange. I guess the one guy did call the project foreman. But why isn't he just directly calling me. So frustrating.

So how long ago did they do the roof?

As someone noted I had a spot on my shed I did 2 years ago, the felt had a bump which resulted in a bump in the shingle but it did go away after a hot summer. Not saying that is guaranteed but a possibility

Gotcha and thanks for your reply. They finished it on Monday this week. Today is Friday. The roof guy himself even said it's had enough time to settle in if it were a cold/heat issue. So, I don't think that's the issue. And I do think it may have been doing this prior to the new roof. I'm just wondering if they should have fixed it and / or asked me what I wanted to do about it.

When you talk to the rep don't let him go until he's either explained it so you understand or agrees to rectify it.

It's not uncommon for the guy who does the bidding and checks on issues not to be part of the crew that actually does the work.
