The roofers finally made it out.

The roofing is steel, which comes manufactured already sealed and painted as a big coil of metal.

The roofers have a machine which unrolls the coil and forms it into the profile of the roofing. Each piece of roofing is made as the entire length of the roof from the peak to the bottom edge. There's no breaks, seams, or overlaps anywhere from the top to the bottom. (This process is similar to how "seamless gutters" are made.)

Side to side, each piece overlaps the previous, and covers the screws that hold down that piece. A raised lip, or "standing seam" connects the two pieces and ensures that water can't get between them. Each piece is about 16" wide.

The solar panel racks will clamp on to the standing seam (rather than to a bolt drilled through the roof,) which means that there are NO penetrations in the south side of the roof at all! Zero! It's nearly as leak-proof and permanent of a roof as can be designed.

Here's some photos.











One thing I've noticed so far is that the color of the roof seems to change, depending on the light and the weather. It can look mint green when it's overcast out. When sunny, the color stands out much more the way it should, sort of a bold teal. Please also try to imagine siding on the building, which will be sort of a light buttery yellow, instead of that awful blue-green foam!

The style of this metal roof is called "1-inch nailing strip". You can see a good view of the profile on S-5!'s web page for the N style clamp they sell.
