Sorry you are having problems! Those bumps might settle down when the shingles have a few weeks in the hot sun to mold themselves together.

As for the vent issues, you might try posting in Home Repair or Roofing (if there is a Roofing forum) about that. Probably some roofers over there!

Good luck.

[EDIT: Home Repair has a ton of threads if you search it for 'roof vents'. The first few were all about which kind of vents to use - right up your alley.]

I can only say make them do it right. Even if they have to redo it. I'm still getting my new roof put on. I think maybe they started in June? Anyways, watch the GAF roofing installation videos and read the installation instructions. Compare that to what is going on with your roof.

At first I was nervous having them tear up so much of the new roof. But in doing so I found more and more installation errors. Luckily the owner of the company seems to have taken ownership and has torn up and redone quite a bit of it. They have definitely spent more time fixing it than putting it in.

I told them that none of the installation crew was welcome back on the job. I also tried not to deal with the assigned project manager because he is the guy who dropped the ball and created this mess. I try to only deal with the owner or people who do not have a stake in the initial installation.

I just couldn't stand the look and made the company remove the ridge vents and redo with standard ridge finish and vent boxes on the backside of the house. To their credit, they've got a sales guy who will let you rant and just look at you, and then tell you that he wants you to be happy. And frankly, everything looks cleaner, straighter, and more acceptable without the ridge vents. The ridge itself was straight, but the ends were godawful.

At least they sent a second team that had an English-speaking member who could communicate with us, and they knocked off by 7 instead of 9. I count that as being listened to a little.

The misadventure included a big hole poked in the bedroom wall (a change in elevation outside and they somehow breached it when installing a skylight), an unexplained power outage that affected half the house, deck furniture and flowerpots pushed all over the place and not put back as promised, damage to some décor, and nails remaining in the flowerbeds. And this is a reputable company.

Good for you! If more people insisted on a good job these shysters wouldn't continue to exist. I read all the reviews, checked the the tons of positive and only one negative BBB review and got personal recommendations (the project manager's sister lives nearby and was one of the recommenders) so thought I was making a good choice. I can only surmise that people are either really ignorant or most of the positive reviews were fake and the negative one was the only real one.

My skylights have yet to go in but they are bringing in an outside guy for it. I think they should have done them first because they have to tear up the new roof to do it but I will have them redo that section of the roof. My sales guy frustrated me because he kept trying to say things like the vent pipes were crooked before, that was like that before etc but luckily there were pictures.

I had specified they need to cover my flower beds with a tarp. They did some but not the main part so I ran out there with my own tarp. They took it in the end but after I told the owner he bought me a new one. Lots of the drip system in those beds were damaged from all the traipsing through. With a tarp properly applied at the beginning they wouldn't have had to walk all over it so much.

My roof was comically bad. Shingles uncut and overlapping the gutters, wrong underlayment put down (mix of synthetic and felt when I specified synthetic in the contract), nails galore showing, nails left between shingles, nails not covered with caulk on the top layer, ice and water shield not applied to the eaves as specified in the contract, vent pipes crooked, they pierced the drywall though in my master bath by pushing down on the vent pipe, bent trim, ragged trim, gaps between the lower roof and upper roof, metal flashing torn not cut evenly, metal flashing unprofessionally bent into place unevenly, gaps in the trim, water diverters not reinstalled properly (twice) that sent a waterfall over my front door, shingles racked or not set at proper offset to each other, edges of shingles not cut properly so had dangly bits on them, starter shingles showing where they cut back upper layer too much, gutters sliced and dented and that is all I can think of right now.

I've got to give props to the owner for being reasonable and helpful. I offered to let him out after the install by giving me my money back and walking away but he wanted to tackle it even though it was going to be painful for both of us. My preference was that he walk away. But so far I haven't been unhappy with his redos. As long as he is personally here supervising things seem to get done well. No leaks so far and things are starting to look very nice. The new color really compliments the house and the new shingles seem to add a bit of sound proofing.

I still have a three item punch list but I'm letting them rest until after the skylight guy is done.

I wish I had you here to check our job - I don't think it's perfect, but don't know enough to be sure what all could be wrong. I forgot to mention a leak that developed in a covered patio from an incorrectly installed rain diverter. There are still a couple of suspicious junctions, but I'm exhausted from dealing with it.

Yeah it is exhausting. I didn't want to look at it after a while because I kept discovering new things. But this is your only chance to make them get it right. Try watching the GAF installation videos on-line. That helps educate you on what to look for. I also had them double their warranty from 5 to 10 years and put in a clause that if we sold the house and the buyer had any issue with the install they would correct it. I asked for this before I let them continue to work on the house but after they had done such a terrible initial install.
