Metal, hopefully the snow will slide off in the winter and fire won't burn the shed in the summer.

Metal at the cabin for fire protection.
Metal on the suburban home for long life and an annual insurance reduction. Plus we liked the look.

We used 26 gauge. There is a lot of 29 ga available at home centers. The lower the number, the thicker the metal.

I used metal mostly because I plan to harvest rainwater.

Which colors are available and does the red metal color fade to pink eventually?

We have a green, metal roof. The colour hasn't faded at all. In the winter the snow slides off so we don't worry about snow load. We do have to make sure that if the door is slammed, and the snow decides to let loose, no one is standing too close or they will get hit by the snowslide. *S* I like the sound of rain on the roof at night. Very relaxing. *S*
Due to the amount of snow we receive here, we can't have eavestroughs to collect water. Snow sliding off the roof would take out the eavestroughs if they were there. That is the only down side I can think of with a metal roof. We definitely prefer it to shingles.

Regarding snow. If the roof structure is built to withstand the expected snow loads gutters can be installed for saving water as long as devices are installed to keep the snow from sliding off. This has been done in Switzerland and Austria for years/centuries.
The more elegant solution is to use "snow birds". Many rural locations I've seen over there use a more utilitarian method. Pipes are mounted just above the roof surface near the eve, parallel to the eve. They keep the snow on the roof. And they do get a lot of snow there.
The roof shown with snow birds is slate, just about as slippery as metal.

If you are going to do any amount of rain water harvesting the metal roof would be the way to go also.

Does anyone have a concern of metal roof being too noisy during rain?

Not if it's installed over osb or plywood sheathing and the attic or roof itself is also insulated.

here is a link that you might find useful, it has helped me in planning my metal roof, mostly on the "How to install the panels properly" side of things

Quoting: nathanprincipe "How to install the panels properly"
Quite informative.
Boy, things have sure gotten complex, and even exotic in most every aspect of life, it seems. A lot of wrenches were taken out of my hands when electronic ignition came to be, and try DIY with anything digital.........felt like McGyver when I had to swap out a thermostat.
Now tin roofs come in all shapes, grades, and sizes.
I plan on having a straight roof (no hips or valleys, or even a ridge) on our next structure.
What would be wrong with just slapping down some corregated tin roofing with rubber washered screws, caulking, and forgetaboutit?

Gary O, I completely understand your mind set, I feel the same way alot of the time. My approach when I first started to plan and build my cabin was to keep everything as simple as possible, though I have found the more Involved I get in building it, it starts to consume my mind and thoughts. With that being said I have started to analyze and research every detail. Some times I have to step back and remind myself that Im not building my dream home, but a place to retreat to one weekend a month........... Back to the roofing thing, what I have found through my research is that 2 things are to be considered when applying metal roofing directly to the structure ( no sheathing or underlayment). 1 is that your roof will have to be sufficiently vented because moisture will build from condensation and could leak down to your roof insulation, and I dont need to explain how that could be bad over time. 2nd is that the nailing pattern should be sufficient enough to hold the roof structure from racking and swaying, otherwise wind and or other forces will move your structure back and forth just enough to possible wallow out your "water tight screws" and a leak occurs at that point. I decided not to sheath my roof because the structure is to steep and high off the ground so I will be installing my metal roof directly over furring strips that connect to my rafters.
If my project doesnt turn out to be as good or "professional" as I might hope, I still have to tell myself its better then sleeping in a tent all the time!

Yeah, I hear that.
However, I plan to use 2x6 T&G or car decking for initial roofing.
Hope the photo shows that well enough.
BTW, great build Nathan.
