Metal Roofing Question

[gregs]

Quick question. Do any of the metal roofing suppliers cut the angle for say a hip roof when they make the sheet? Or is it all cut on site?

I can’t guarantee that they all will or all will not.

If you cut the sheets on site you can accommodate any small errors in measurement or design changes.

I see the ads on tv for the metal roof suppliers and it looks like they use a computer program to do the layout. Was wondering if they had the ability to precut the angles as well. Obviously you would need accurate measurements.

I'm in the industry and I've never seen a manufacturer cut panels other than 90 degrees due to the tooling they have in the shops. I've always specified those as "cut on site".

Metal building business here. We have always cut angles on site.
For the supplier to pre cut, all of the sheets would have to be precisely layed out and there could be no deviation in the field.
I have seen machines that cut angles for use in the field but they are very expensive and not really worth it.

Thats what I figured, but thought I would ask about it. I'm sure the whole accurate measuring and dealing with variables is the problem. Was just thinking if they had a way to cut the flat coil on a angle as the panel is finishing being formed it could save some time. I looked at the manual panel shears years ago that match the profile of the panel and come in different angles.

Obviously you would need accurate measurements. I cut wall panels on the ground. Would do roof panels the same. Cutting after fastening the panel can be dangerous and difficult, and if you’re using a grinder with a cutting wheel, you might be throwing steel dust where it’s hard to clean off and it’ll rust.
