Original post: Care to comment on a new roofing job

babaganoosh Member

We just had a new roof put on along with skylights.

We have not had the best of luck with contractors. Not sure if we expect too much.

I really don't know much of anything about roofing.

I took pictures and wonder if anyone could comment if these look okay.

Other people we know used this installer. They are supposedly preferred/certified.

Not sure if I just worry too much or know just enough to be dangerous. Other people aren't going on their roof to look over the work of a pro and second guess them. I kinda didn't want to go up there because I figured I'd see things I'd wonder about. But I needed to go up there to install an antenna.

I found about a half a dozen nails laying up there. Some heads were pushed into the shingles (like someone stepped on it?). Do these cuts self-heal? Are they a big deal?

Does the flashing around the skylights look okay?

Should the flashing around the chimney be above or under the shingles? I would think water would run down the roof and get under that metal. Or is there also some of that metal under the shingles?

I saw this ding in a shingle — something gouged it a bit. Is it self-healing? There are loads of other layers of things below, will that stop water? Or is it a problem?

Should walking on the roof cause some granules to come off already? I know the old roof had loads of granules in the gutter. Not wanting to disturb the roof was part of why I didn't want to go up there. Is walking on a roof a big issue?

I think you're being overly critical.

Yes, there should have been roof sealant used on the exposed nail heads.

Yes, the shingles should have been slid under the chimney flashing just on the low side of it so water would run over it, not under it.

You did not say exactly how far those shingles hang out beyond the roof in that gutter area.

You want it hanging over about 1 inch so water does not run behind the gutters.

There's always going to be a few loose granules on a new roof.

In a few of those pictures, I would be upset if that work was done on my house. I just responded to another user's recent post regarding roof work. In my honest opinion, many roofing contractors are cutthroat pirates. I don't know if they think you won't climb on a ladder to inspect their work or what.

A friend told me about a guy who put a vent on the roof without cutting the hole in the roof. It was on an elderly couple's house.

Depending on how hot the weather is we would even brush off the shingle "crumbs."

I would get someone else up there to inspect. The problem you may run into is: will that person protect the previous contractor's job or be honest and touch up/correct any mistakes?

If nails were left on the roof I can almost guarantee nails are on the ground. Do you recall if they ran a magnet around the house? My first summer as a grunt I was responsible for the final pass, that being any nails or debris on the roof/ground.

Norm — I would agree with you but then people point out issues. I may be paranoid, but that doesn't mean people aren't out to get me.

Lip — what are some things you see that you take issue with?

Joe — how would you correct the chimney flashing? I'm not sure which side you are saying is the issue? The right or left picture? I am thinking the right picture? Does water run down the roof and under the flashing?

We asked for some spare shingles for repairs. The guy said it's warrantied, call and I'll fix things.

I envision that's his laissez-faire answer to issues. Yeah, I'll get up there and caulk the nail heads, the chimney flashing. The guy either gave a story about never having a problem or said there are other things under there that are protecting things or said its under warranty, so give me a call if you see water and we'll fix it.

Oh, Lip — the ground didn't have nails. He said "we go over with the magnet brush. You see three nails, we come back."

That's how he was — a good salesman who hit the details. We use 5-ply plywood, not 3-ply plywood which is not as sturdy, costs more but worth it. They were up there with leaf blowers. So it's weird finding the loose nails up there.

I don't like some of those holes/nicks where the nail went through. Skylights seem to be problematic to begin with and I don't like that one seam. I've only known three or four people with them but they've all leaked over time. It looks like you can see the white underlying material in your one skylight picture. In my limited experience, and again I haven't worked on a roof in a long time, but I remember all flashing being under the shingle regardless if it was at an edge or a chimney. If I were to do it the way they did in the picture I'd have a bead of sealant/tar around the flashing edge. And I still don't think that would be the right way to do it.

I kinda don't like looking "behind the curtain" when I get work done because I'll question what I'll see.

I went on the lower roof.

He talked about the roof behind the chimney. It would catch leaves and be wet back there. He talked about putting in a cricket. There's no cricket there, right?

Should shingles be this close to the roof? Seems like snow/water will wick into the shingles and there should be some air gap between the shingles and the roof.

That's not the case here. And this is one layer of roof. I think there were two layers before.

Is that fixable now? Do they trim the shingles?

Is it just me being picky?
