How steep can one put up a metal roof?

[JethroB]

A roofer that does steep roofed churches?

Keep in mind metal roofs are a barrier to RF energy.

Does that mean what I think it does Brain?

Yes Pinky. Yes it does. They won't be able to listen to our plot to take over the world.

No one has stated the obvious answer?

The steepest a metal roof can be is about 89 degrees. At 90 degrees it becomes a metal wall.

Seeing as metal siding can be attached vertically there should be no questions about roof pitch.

Biggest problem here is building department issues due to house framing movement when snow sheds. When my barn sheds you can see some movement in framing. The inspectors say this causes damage to drywall, etc in houses that weren’t designed to handle the shedding.

seems like smoke and mirrors to me, but i was told I couldn’t use metal on my house, unless I put in anti shed plates, but those tend to tear off and leave holes in roof.
I went with 50 yr shingles.

Yeah, sounds like BS to me too. Seems to me the whole point of a steel roof in snow country is so the roof will shed snow. If a building won't handle shedding, it probably won't handle large snow accumulation either. Steel roofs are quite common here, never seen a problem with one.

I agree. But they say truss systems are designed differently for steel roof. I don’t believe this. But instead of fighting it , and the fact that wife didn’t want mounds of snow blocking window views, I went with asphalt. Ive had 5 feet of standing ice and snow up there......still standing.

I'm in the middle of putting a 12/12 metal roof on a she shed for my wife. It kind of sucks to do but I like the look both inside and out.

That is similar to my house. I would recommend a custom roof, put on by a reputable roofer. Mine is crimped over, no exposed Fasteners and all joints caulked. We did a total tear off and ice and water on the entire roof. For those that say its noisy, it's not. The metal sits right on in the Ice and water so nothing to be noisy. It's no different than my previous shingles.

Ice and water shield + sheathing is a big help. One of my farms metal barns I store tractors in is so loud in a heavy rain, it really hurts your ears. Of course it’s one open room with little sound absorbtion

One of the reason I chose to build here. No violent rains, no damaging winds and snow accumulation - usually less than 12". I had 50 year shingles installed 15 years ago. They should last the remainder of my life.

Just an occasional volcano....lol

You can put one up on A-frame roof pitches of 16/12 or more. I slid around a bit on a 5/12 pitch in cold weather. I wore sneakers. Sticky climbing shoes would have worked better.
