Finally building my storage shed.

The pitch is pretty steep. Looks like 12:12 maybe. Whatever it is, much more than 4:12. But, I just checked and the rafters are 4' spacing.

I seem to have trouble with metal roofs... just could be my size isn't a good match plus they sure get slippery in the Pacific Northwest.

So far a quality comp has been the best for me all around... I always use 30# felt and double coverage... my first complete roof done by me was in 1982 and not a single issue... 35 years now and these were bargain shingles at the time...

I was considering a metal roof here in the Pac NW on my house but the roofers quoting the work talked me into a 30 year composite. Said too much moisture forms underneath.

My tin roof keeps getting punctured from falling branches. I have numerous leaks to fix with buckets underneath. It's steep, slippery, and probably has large numbers of exposed screws to slide across if I ever lose traction. Doesn't sound like a fun repair project ...

Due to their size, I have to hire out tree trimming, which is expensive. I keep trimming the centuries-old oaks nearby but they keep dropping branches anyway.

The pole barn room is metal and has a few "Punctures" from trees dropping things in windstorms.

I've been trying to be Firewise and am constructing defensible space around my house and outbuildings. Wildfires are about the only thing that scares me. All my trees are at least 20-50 feet away from our buildings. Nothing is going to fall on the roofs and puncture the metal. When I remember how to estimate the height of the trees, I may increase the distance.

What is the spacing of your trusses and how steep is your pitch? One of the advantages to metal over shingles is that you can space your trusses out a lot farther. Shingles need trusses 24 inches on center, or closer. I personally space my trusses out 4 feet and then use 2x4's on the flat for purlins across the trusses so I have an easy target to screw the metal down. Pitch is how steep the roof is. For metal, you can get away with 2:12 without any issues, but for shingles, you should never be less then 4:12

"you should never be less than 4:12 "..... is not quite correct.
Manufacturers recommend not less than 4:12, for shingles, but....
WILL warranty a shingled roof down to, and including, 2:12 pitch, if Ice & Water Shield is used.

I would need some major logging to get 50 foot clearance between my tin roof and trees ..... the building is 24x36.

Awesome trees! As much as I love trees, those would be far to close for me. With wind, disease and the possibility of wildfire, I wouldn't be able to sleep at night.

Neat picture with the snow and the lights. Will the snow affect the OSB on the walls?

It will be fine. I wanted to get the tyvek on to protect it from water but it will be ok till spring. There is 24" of eve so it does pretty good.
