Metal Roofing from supplier - scratched

[ururk]

I usually write a long winded description. I've linked to a Flickr photo album of some of the scratched pans from a metal roofing supplier. Are these scratches something I should be worried about?

I'm primarily concerned about the metal rusting through.

The mfg of the steel says the paint warranty is still valid, except of course any rust areas due to scratches will be excluded (which would be expected).


Long-winded explanation:

I purchased some metal roofing from a local sheetmetal contractor. He did all of the trim work - the bends were perfect but his QC was a bit lacking - the plastic covering on the trim was not in the greatest shape. Still, once removing the plastic the metal underneath was OK.

22 gauge, Kynar over Galvalume AZ50.

Fast forward to the pans... out of 175 (approx) pans, about 50 had to have little touch ups - which I expected. However, 24 have scratches that are too long or too frequent to paint over. I put together a Flickr album with pictures of some of the pans.

The long scratches will catch a fingernail, but no glint of metal.

What I don't have are photos of the scuffed panels - several of the 24 pans have white scuff marks.

Here is where I screwed up - I already paid him for the balance of the project. I'm an idiot, I'll admin freely.

Any advice will be appreciated. I feel like a fool at this point, and don't really know what to do.

I emailed him - he said he might be able to replace a few of the pans with extra from another job, but haven't heard from him since.

Did the installer give you written repair / replacement warranty that matches the steel manufacturers warranty for the paint?

If not, will they?

Some of it is machine marks and there is no excuse for that. The scratches are poor handling. Maybe they hoped you wouldn't notice them on the roof. Scratches happen but that is excessive. I would want them replaced. When we do a SS roof I usually order some extra panels for just this reason.

I'm the installer. I would have to ask him to write up a warranty to guarantee the scratched pans won't rust. I'm not too certain he'll do that.

Correct. I was out of town when he delivered the panels - I was not expecting them while I was out (but that is on me for not communicating it well enough). It was raining, and they just decided to unload them in the rain, so I suspect they made a quick job of it. I had to (carefully) remove each panel from the piles and wipe them each down and restack carefully in the barn.

Quick update - he has 70' of coil leftover from a project, some flat sock, and can reuse some of the pans by cutting them down (hey, that's not my problem if he reuses them). So, this might get resolved somewhat, but I don't know how to proceed if he won't replace all of the scratched ones.

 

[ururk]

70' will only do 10 of the 'A' pans, I'm doing a final count tonight.

 

[ururk]

I went out tonight and did a final count. I have this many bad panels:

A: 1 - would not snap down, warped

A: 10
B: 1 (I painted over a bad scratch, and am probably OK not replacing this one)
C: 6
D: 0
E: 0 (One has some short thin scratches, probably can paint over)
Short: 24

End pieces: A, B, C, D were scuffed, but since they are the end pieces, I'll thinking I'll just touch them up.

Total linear ft: 168

Cost-wise, for a 16" SS panel / 3/4" rib, how much could this cost? The mfg is CMG (Coated Metals Group), one of their metallic colors.

I've been doing sheet metal for over 28 years. These scratches are from multiple handlings and carelessness when transporting. That being said, I wouldn't worry about any rust through on 22 ga unless it was a very deep scratch down to bare metal. Chances are pretty good that you'll scratch them during install too, it's hard to avoid sometimes. Luckily, NONE of this will be visible within a few weeks. Your roof collects an amazing amount of dirt, and small scratches disappear...

if it showed up scratched from the supplier. Take it back and get some unscratched stuff

 

[ururk]

I've been pretty good about not scratching the panels as I've installed them - I only scratched my transition flashing and that I touched up immediately. The same when hemming - I've been very careful with storage, storing them vertically and inserting two pieces of newspaper art the top of the pan (longest pan is 7') to keep them apart. A bit excessive.... yes... but since I'm doing the job might as well take my time and limit the amount of touchup.

The scratching/scuffing probably won't be visible due to siting and pitch of the roof, height.

I'm really concerned about long-term (20, 25 years) rust formation. I did a metal roof so that in 25 years I won't have to replace it. The long thin scratches are what worry me most - the larger scratches I have paint for, as much as it bugs me that there are quite a few.

Hopefully I hear from him today - I sent the list.

I stopped there this morning. He was surprised, didn't know what could have caused the scratches - but will be running all new panels with stock he has on hand. I know he will be using some of my pans, so it isn't a total loss for him - and he had extra left over because of some minimum purchase amount on the job he is doing right now (hence the extra). So... I'm a bit worried but hopeful/

Sounds like he's trying to make it right. Good luck. Remember to only fix one end of the panel so it can expand and contract. One of the major pluses of standing seam.

It's a built-in flange style, so I have to put screws every 18-24 inches. He did say to make sure the top screw was in the top of the slot to keep the hem from popping out of the bottom. I wanted a clip style... but he doesn't have a die for that style panel.

Did you not say the metal came protected/covered w/ plastic?

I have never worked with the painted stuff

Just the trim has plastic covering...

the plastic covering on the trim was not in the greatest shape. Still, once removing the plastic the metal underneath was OK

In talking with him this morning I asked why the pans didn't come with the plastic. He said that it was very difficult to remove once bent, and it adds 5 cents/sq ft per pan. Honestly, I would have paid the extra had I known - we're only talking about $70ish dollars. I don't mind taking a bit of time to remove it. He did say he has been thinking about buying an add-on to his machine to add a blue plastic to the pans to protect them.

Update:

He was able to run all new pans for me. As he was running the material, he discovered the coil stock was damaged - it wasn't his machine. Evidently he must have run some of my pans on stock he had on hand, as he wasn't sure which metal supplier they came from. I don't really care - I'm just happy he was able to make new pans for me. I'm picking them up tomorrow.

 

[ururk]

Picked up the pans - he didn't make 6 of the C's as he forgot - then he realized that was why he had some material left over. He has to order 3 sheets, which he will be doing.

Of the pans he made for me, they were all OK. I hemmed a few and...

They are not snapping easily. That is to say, I hit it with the mallet I've been using on the other pans (I've put over 50 pans on) and it just doesn't lock down. Even new pan to new pan, I had difficulty snapping them. I was only able to get 4 pans on, and they are all dented along the rib where I had to beat on it. They are locked in, I tried prying on the pan. Not too concerned about the ribs, too far to see any dents, but something is off.

It is colder today than it has been - 32/34 versus 42/45 - could that make it harder to snap? I'm going to email him but I don't know what to say.
