I had 6 valleys where the roof basically turns at 90 degrees. With large amounts of snow, ice builds up on the tin (some say it is poor insulation, others say it is the nature of the beast) and as gravity sucks it down the valley, it rips the tin. A heavier tin will help but it may still rip. I had valleys rip and flashing rip. The manufacturer replaced the tin the first year but after that I was on my own. I had a combination of 8/12 and 6/12 slopes. Like I said above, without the valleys the tin works great.That's funny you mention that about your house, I was kicking around the idea of putting tin on my roof. Shingles are done, so I need to replace later this summer. Other than re-tightening the screws, what were some of the other cons of tin? ( apologies for the topic segway ).
If you are in a snow belt when you close your front door it is usually the time it starts the roof avalanche. Tin directly over plywood for some reason causes black mold on the bottom side of the plywood... moisture maybe.That's funny you mention that about your house, I was kicking around the idea of putting tin on my roof.

Wonder how metal shingles would fair out? Might be better than corrugated metal sheeting, but shingles period are reasonably inexpensive for sure and to a degree no sliding of snow.I had 6 valleys where the roof basically turns at 90 degrees.

When we replaced the tin with asphalt shingles there was no movement (no avalanches) and no problem.

I didn't want to take the chance.Wonder how metal shingles would fair out? Might be better than corrugated metal sheeting, but shingles period are reasonably inexpensive for sure and to a degree no sliding of snow.
This isn't with the keeping of the thread but I suppose since I started it, I can add to the derailment. It is better than all the COVID/Conspiracy BSneed better airflow, roof vents,whirly birds, clear soffits
That's a pile of snow for sure, you must have had a front end loader. Did you move to the banana belt now because of that amount of snow lol!I didn't want to take the chance.

With today's builds, there is lots of attic air flow with the soffits available and/or roof vents. The simple solution is a straight gable roof; plain and simple. A good design will not have any doors or basement windows below the eave where the avalanche debris pile ends up. I learned that from experience.
Note the garage doors, they are south facing. With the metal roof, the apron was a chore to clean of snow when the roof slid. Prevailing winds were from the south and the north side of the house avalanched much more. The rear door/railing was a real pain with the metal roof. With shingles nothing slid. I replaced the log railing just before I sold the house and I don't know how the aluminum railing held up but I wouldn't think very well. Easily 6-7 feet of snow on the concrete pad below the wooden deck. Proper design is very important.
The real reason for the black mold, had to mitigate a few roofs with this problem. You will have to back this video up to the start.
It was all by hand other than the driveway (used a quad with a plow). The last two years I did have a snow blower for the back of the house.That's a pile of snow for sure, you must have had a front end loader. Did you move to the banana belt now because of that amount of snow lol!
Well ferniesnow actually covered how to address this issue in his building code comment.Heating an uninsulated building is a no no, I've heard sea cans are bad and rig buildings
Warmer air on the underside of the tin causes condensation, airflow evaporates that moisture before it gets wet.
Looks awesomeNew client this month (July 2022). A 12’x 8’ “play house” for a young daughter. The son has a tree house so they had this built for the daughter.
