Any professional roofers here?

[Dexter]

I'm getting a metal roof put on my currently under construction home right now and wondering if I'm getting taken...

They first put down a blue glue, then applied the blue peel and stick (for winter I gather). I was told that the home is now waterproof. Well... after the big rains last night, the roof leaked.

The builder said there was a couple holes in the peel and stick. One specifically being a hammer dent. They fixed the holes with some sort of glue/caulk (what I don't know).
I'm sure shoveling off the snow created multiple holes over the roof, most now covered in metal without being fixed.

He tells me once the metal goes up it won't matter anyhow, and that I shouldn't be worried. REALLY?? That peel and stick was expensive, it shouldn't be full of holes?
Maybe I'm wrong but I worry about the fact I will be in this house forever, and I chose metal because it should out last me!!!

Any ideas? Suggestions? I don't want them to rip it off but will ask them to if required.

AND while I've got you, how long should a warranty be? I don't mean the 40 years for metal, I mean how long should I expect to be leak free?

THANKS!!

the underlayment should be a butyl rubber used to seal around the nails/fasteners that hold the metal on. as far as leaks, if the roof is installed correctly, you should get the full 30-40 years bar any wind or mechanical damage like tree limbs.

Thanks for your response.
I see what you are saying (in an ideal situation, as per manufacturers suggestions)
But, if there is a fastener/nail failure- will the water not enter into the area between metal and membrane, and leak into the house?

There are surely multiple small tears in the membrane, mainly from shoveling snow off with a ragged plastic shovel.

You being in B.C. and me being in Kentucky. Things might be done different. In Kentucky I would have put tar paper on to protect from the weather. Then when putting on the roof I would put fan fold board down and then the metal roof.

Tar paper to keep water out and fan fold board to keep condensation off the tar paper so it wont trap mostiure under the metal.

With small tears in the peel and stick after the metal is put on the roof shouldnt leak.
Just have the builder cover the tears with a patch of peel and stick or tar paper.

If you have valley areas on your roof make sure that those are 100 precent water tight.
Its your house and its your right that the repairs are made to the peel and stick.

There are different styles of metal roofing. There is the kind you see on pole barns ant there is the kind called standing seam. Standing seam is flat except at the seam.

I believe the blue "ice shield" should be totally water-proof. Under the pole-barn style metal roof, you will get a fair amount of condensation. Any holes in the membrane will collect that moisture, eventuall leading to mold and/ or rotten wood.

You can't put metal roofing over snow, but I don't think shoveling is advisable, either.
IMHO, the leaks in the membrane must be repaired before the metal goes on.

What are they using as fasteners? Screws or nails?

who did the shoveling. if it was you than you don't really have a leg to stand on and better get out your check book if you want it fixed. if it was the contractor then they should make it right, by right I mean that the underlayment should be waterproof on its own. if it leaks now, it will leak when condensation gets under the metal. I've used underlayment on numerous roofs in the rocky mountains and they stayed water tight for several years before I got the metal on.

First of all the 40 year warranty is only on the paint, if the paint comes off they'll give you a panel to replace that panel with. Pretty much a uaeless warranty. Most of the players involved will be long out of business in 10 years or less and installing 1 new panel will look terrible and wouldn't be worth the labor. I have heard of them paying for paint so you wouldn't have to replace the panel, that's right YOU because no one is going to pay the labor.
I'm guessing whatever was agreed to beforehand and written in the contract is what the roofers warranty is. If it's like most there is no written contract so there is nothing stated so it's just good will and up to the roofer.

Where are they putting the screws if it's a ribbed roof? Did they pre drill the holes?

[Dexter]

It was the contractors labour who shoveled the blueskin, not me. Personally I thought they were being rough but the stuff is supposed to be invincable (...)
Yes screws are in pre drilled holes.
What I was worried about was moisture including condensation weeping through remaining holes.
Naturally, it is unlikely they will find all the holes.

[Dexter]

Yeah, half to 2/3 of the roof has metal already.
I would love it if they'd pull it up and take a look, however that could cause as many or more problems too, especially since it is cold out, less pliable.
It's a pretty upsetting situation.
