New metal roof leaking, need advice.

[Rustyiron]

It did not leak before the ice, but my question is, has anyone had experience with a metal roof leaking after an ice storm? I don't see a place for water to build up, but what do I know.

Ice (damming) will change the "rules" for any type of roofing material. It's a challenge to locate the problem and correct.
Are you heating any part of the building?

Get with that roofer before things dry up. He should be able to find it and trace it source quite easily and above all remember one thing, BE NICE. Be nice until it’s time not to be nice anymore.

Well, how do we know when that time is?

Sorry it I missed it, but was it real windy when this happened? I'm wondering if wind was a factor forcing water where it normally wouldn't go, like through or under the ridge vent somehow.

That gambrel roof is such a steep pitch, you'd think ice damming or any pooling would be a non-issue.

Any penetrations are the usual leak spot on a standard old school metal roof. I had an Amish metal roof put on my home about 4-5yrs ago. I had to call them back twice to replace and add more ice/snow rails because of the amount of snow I get. Metal roofs are great until you get giant glaciers or snow/ice sliding downward, removing everything in its path.

When my pole barn addition was built, they missed a couple of girts when installing screws on the roof. The screws were off to the top or bottom side of the girt but, of course, just stripped out because they didn't have anything to "grab on to" so they didn't tighten down on the gasketed washer and leaked.

I could see each place where this happened because there was no existing roof, but if that is what happened on your building, it would be impossible to see.

Pretty sure this is not condensation.

You sure the floor spots are not originating from the outside walls?

And are these nails coming through the roof? I had thought your new roof was panels and screws.

Dalton will tell you when that time is (Roadhouse ca 1989)

Those look like they missed when nailing the plywood filling the hole (corner).. and then the nails from nailing the furring strips on (across the center)..?

Just hope you did not have a contractor that did work like this... and these are not even some of the worst examples.

Nope, I have not used any heat since the fall.

That is really shoddy workmanship.
