How to tell if a new roof was installed correctly

“There was a few things I thought looked odd. My boiler flue and as the guy only took photos from one side I decided to do my own photos and the ridge looks off.”source ↗

“Maybe I'm pedantic, any help would be much appreciated.”source ↗

“Any concerning areas before I make the final payment?”source ↗

“Am I crazy for thinking a lot of this looks very shoddy?”source ↗

“The top right corner of the garage roof is particularly unnerving.”source ↗

“I just wanted to post some pictures of the new roof I got done on my house and if I need to call the contractor back.”source ↗

“I had some flashing replaced with copper a couple months ago, it looks good to me, but I know next to nothing about roofing. What do you all think?”source ↗

“I had a roof replaced today. Haven’t seen this on other roofs I had replaced in the past 2 years.”source ↗

“Getting roof replaced does it look like a good job so far?”source ↗

“Hi everyone, new homeowner here — shortly after moving in, I noticed a leak in the attic where the roof meets the chimney.”source ↗

“I know next-to-nothing about roofing, but the result doesn’t look like I expected, or like other posts of “good” flashing that I’ve seen?”source ↗

“Just hoping for some input/reassurance from those more knowledgeable, thanks in advance.”source ↗

“I don’t know if I’m overthinking this:”source ↗

“The Vented-Ridge Cap seems off to me with the amount of caulk (?) or butyl being used - - the white substance”source ↗

“The metal on the hips don’t seem to be overlapping at all, rather it looks like they are just butting-up-end-to-end”source ↗

“The flashing looks messy, will they keep out water?”source ↗

“The long horizontal “pitch transition” piece to a lower pitch portion of the roof has a gap…”source ↗

“I know nothing about roofing so looking for feedback on how this new roof looks.”source ↗

“If you are a roofing professional, please inspect these photos and tell me if the quality and craftsmanship is good or would you flag any concerns?”source ↗

“This is our brand new roof. They didn’t replace any of the decking. Is that okay?”source ↗

“Thoughts on this Class 4 Roof Replacement for 12 sq roof? $9k estimate”source ↗

“We had our roof redone, and I’m concerned about the work where our flat roof transitions to the shingle roof. What do yall think?”source ↗

“the interior flashing seems to have dents where the bolts are, is that normal or should it be fully straight with not dents after a brand new flashing installation?”source ↗

“there is little a little brown box just sitting there, that seems to have been installed on the roof, does anybody know what that little brown box is?”source ↗

“Tile roof with original felt from 2005, Small leak between the deck boards into the attic, northern California.”source ↗

“But not removing the old felt gives me some pause. He said it's common for a patch job.”source ↗

“what do you guys think?”source ↗

“How bad is this flashing where the chimney meets the roof? Roof was just redone and they also re-flashed the chimney. Should I trust them to come back and correct it or should I have someone else do it?”source ↗

“Does this part of my metal roof look like it was done correctly? I would like to know if this is something that the roofing company should correct before I pay or if this looks okay. If there is an issue with this, how would I explain the problem to them? Sorry I am a total roofing novice.”source ↗

“I am concerned about the waviness and curling up on the edges on a decent number of the shingles and ridge caps.”source ↗

“Is this considered a pro level job?”source ↗

“Looks like half decent materials and garbage workmanship to me.”source ↗

“The obvious buckling is a pretty big red flag.”source ↗

“I am concerned diverters will just hold leaves and debris. If there is already a cricket and counterflashing is installed correctly are diverters a positive or negative?”source ↗

“The roofer said the issue was caused from a nail that fell through and that he caulked it. I was under the impression he would be coming back to finish repairs once dry but the builder is saying the repair to the roof is complete.”source ↗

“Is it okay that a roofer never entered the attic to inspect the damage? Is there anything I should ask about or be aware of?”source ↗

“Just got a new roof recently installed - I’ve been noticing some waviness and the shingle install, and some weird looking venting - see pics. Is this normal or am I overthinking this stuff?”source ↗

“I just had this done, will it perform?”source ↗

“I was/am out of town and have no way to inspect this for at least a month.”source ↗

“Are those screws/nails okay?？Won't water leak through the screws/nails?”source ↗

“same situation. When raining, won't the wate leak through the nails/screws?”source ↗

“Nails into the siding.”source ↗

“I dont want to go back to them usless its really a potential problem.”source ↗

“Hoping to get professional opinions before I do anything.”source ↗

“I’m a typical homeowner, not in the trades. Do you have any concerns about the flashing sitting on top of the shingles without sealant or is that normal?”source ↗

“Thank you for exposing in detail what’s happening. I appreciate having a little understanding of the work.”source ↗

“I thought the same thing when I had a new roof put on.”source ↗

“I was told it would settle overtime and not to worry but I would like your advice, is this supposed to be like this when new or is it a bad install?”source ↗

“Should I be concerned that the flashing does not always go into the reglet. They cut about 1/4" to 1/2" deep and the bed in the flashing is only about 1/4".”source ↗

“what do I know as a home owner...”source ↗

“Is this a real problem? Does this proposed solution make sense? Is installing new decking over the existing decking across the entire roof a reasonable way to handle this situation, or is there another approach we should be asking about?”source ↗

“Before I ruin my roofer’s day with this complaint, I wanted to double-check with roofers here about the flashing and panel installs:”source ↗

“At the two intersections of the ridge & hips, I can confirm that the ridge is higher than the hips… but whether or not it respectively overlaps the hips at the intersection, I can’t tell… and it seems (and feels to me) that the panels are butting-against each other and folded rather than overlapping.”source ↗

“Ive never seen that.”source ↗

“Does this like right to you? I mean cmon, no this is not remotely correct, that’s clear as day to see”source ↗

“The shingles are not properly staggered, there aren’t enough nails, God only knows what is causing the buckling!”source ↗

“AI analysis of the photos is strongly telling us that the roof looks wavy from warped/soft decking. Thoughts ? We prefer professional human opinions obviously.”source ↗

“We had a roofer do just finish some work on our condo. AI says it's not right, and it doesn't look quite right to me, but it'll be a great relief if somebody can tell me, "Yes, this is good, solid work." Any professionals who can offer an opinion?”source ↗

“The repair looks good, I think not removing the old felt is an interesting move, they wouldn’t see if the plywood was damaged.”source ↗

“I would say a 7 maybe? Ice and water shield should always be applied directly on to the deck even if it’s just a “patchwork”, sticking it on to old felt is a hit or miss”source ↗

“Does this look right? We had other issues with the crew, so this is suspicious to me.”source ↗

“They almost killed us I think, BTW, so my suspicion level is high.”source ↗

“scrutinizing every detail.”source ↗

“My roof looks pretty good from far but when I look close up, I have noticed some imperfections. I have no idea if this is normal for this type of metal roof installation or if I should ask for corrections to be made.”source ↗

“I am supposed to be paying the remaining amount in the next day or so but before doing so, I am curious what the experts on here think of these pictures. Should I just accept that it is not perfect?”source ↗

“Just had this installed and several of the trim pieces appear to be not overlapping properly.”source ↗

“I know it's not going to be absolutely perfect but these seem like it should be done with a higher standard.”source ↗

“The crew ran metal valley flashing, but at each valley the lower end of the flashing is kicked up with a visible gap underneath and none are folded flat or sealed down.”source ↗

“Is this an acceptable way to terminate valley flashing, or should each end be folded flat and sealed?”source ↗

“Got a new roof, long story short I’m not impressed with some other things the crew did and it has me concerned about the roof quality.”source ↗

“Anything look off? Specifically the one with the tree covering, are those shingles lifting or is this a common thing with the edges?”source ↗

“They put one on either side of that part. Don’t know why… the vents seem to be common for my area from what I noticed, but again don’t know why I got two extra so low.”source ↗

“I took a different photo of the corner that worries me, is this normal?”source ↗

“Do you think there’s any risk to it not being fixed?”source ↗

“I'm glad I'm not being a nuisance and these are legitimate complaints.”source ↗

“Cost quite a bit of money and although I’m not a roofer, I feel like this isn’t up to scratch. Am I right to want to raise it with the roofer?”source ↗

“I don’t think there should be gaps in behind the flashing?”source ↗

“I also am not happy with the mess in between pots and the crack on the new cement for the haunching.”source ↗

“But I assumed the gaps behind the lead was not acceptable.”source ↗

“Roof tiles are what’s just been added to fill cracked tiles from the scaffold and look a complete shambles too.”source ↗

“I feel like moisture could easily get behind these and just create more rot in a different spot.”source ↗

“I HATE to be that customer that complains, and I know they cut some corners to save me money, but I don't think this would be a difficult fix. Am I wrong?”source ↗

“Does this look correct? Should it be wrinkled like this?”source ↗

“First time dealing with a new roof and don't want to bring up to project lead if this is typical stuff but if it is problematic, I will.”source ↗

“I am wondering how the flashing is here against the house, from afar it doesnt seem like a huge gap but zoomed in it looks pretty open at the peek, will water get in easily?”source ↗

“Is this ok? Roof done today and I'm wondering if this is safe?”source ↗

“Will rain/snow get in? Will wind blow it off? Old roof was flush”source ↗

“I went up in the attic to take a look yesterday and was slightly concerned about a few items.”source ↗

“Without even consulting me, they removed it completely and there is now just OSB over it”source ↗

“In the attic of our extension, the OSB does not meet up in the middle.. i’m assuming this is where a vent is, I can see daylight coming in.”source ↗

“I’m just really concerned that shortcuts were taken.”source ↗

“Is there anything I should look out for before making a final payment?”source ↗

“Other than being a big cutting hazard up in the gutter, will it at least be ok as drip edge?”source ↗

“Was this installed correctly?”source ↗

“I honestly don't know what I'm looking at/for.”source ↗

“Not pictured is scuff marks on the siding from the roofers tossing shingles. Is that considered normal?”source ↗

“New roof being installed. It looks so much worse than our old roof in terms of the way the shingle colors are likening up and these cuts.”source ↗

“The shingles need to be on top the flashing. Any water running down the shingles will just run underneath the flashing. I've never seen it done this way.”source ↗

“New roof, new decking, etc. saw out the second story window that the apron flashing was screwed down through the metal and shingles into the decking. This seems wrong to me as the screws have a rubber gasket and caulking and would therefore be restricted during extreme heat or cold. That seems like a place for leaks.”source ↗

“The roofing company says the fix is they remove the screws, patch the holes with caulk and caulk down a row of shingles over the flashing. I don’t want to accept this flashing with holes in it in a $25k new roof. Advice?”source ↗

“We just had some roofers come through to do our roof and in the back it looks really really weird.. like all the shingles are in different odd shapes and not lined up.”source ↗

“Is that normal? We paid like 20k for the roof..”source ↗

“Most of the ridge vents on the house (1950s house with a complicated roof due to additions) are like the 2nd picture but 1 is open on the end. I can see some sort of white fluffy material. Is this incorrect and if so, was it installed incorrectly or could it have broken (It was installed a few years ago)?”source ↗

“You guys think I'm being too picky? I think the valley in picture 1 looks terrible With the bent and crushed front.”source ↗

“In #5 the flashing is nailed down with exposed, unsealed nails. And it looks like the shingles are damaged on the 4th and 5th row.”source ↗

“I'm not flipping this house, I'm planning to be here for the next couple decades. This wasn't the highest bid, but wasn't the lowest bid either.”source ↗

“Should the ridge cap be so high? On my previous roof you could barely see the underneath part.”source ↗

“The plumbing vent doesnt look sealed.”source ↗

“I didnt even post the pictures where they forgot to re-attach my gutters and the wood below the flashing is all exposed. :/”source ↗

“Sorry for the poor quality. The picture was sent to me, planning on going up tomorrow and taking a closer look”source ↗

“He fixed the wavy ice and water seal by slitting it and overlapping then put the shingle on so basically IMHO doing a shitty repair job to a new roof.”source ↗

“Got it, but should it stick out like that?”source ↗

“Have to replace my roof. Getting multiple quotes. All pretty expensive from 18k to 29k for a 2500 double story house in Seattle.”source ↗

“Can someone tell me which of these are important to consider: - Ridge vent vs regular vents - Class 3 Shingle vs Class 4 - Shingle brand”source ↗

“Some quotes say life time warranty on labor and material. Does it really mean something?”source ↗
