Hmmm...

Quote:
in my case with 4" of snow and an effective length of 29 feet of trailer, the snow load is 1054#
Considering that a 200# person can get up on the roof of an Airstream, as long as their weight is distributed...there shouldn't be any trouble with 1054# of snow/ice on the roof. It's well distributed over the whole top (7'x29'=203sf in your case) whereas a person may be only distributed over 16 sf. (on 4'x4' padded plywood)

200# over 16sf = 12.5# psf
1054# over 203sf = 5.12# psf

I don't think there is a problem...we've never worried about it.

I'm not worried about damage to the roof; not by a long shot!
Its the axle load that was the concern.
Anyway I climbed a ladder and swept it off. We are expecting an ice storm tonight.

If your trailer is just sitting there with a dead load of 1054# on your axles, it's much different (not as big of an issue) than if it's a dynamic load bouncing down the road. Still don't think there is a problem...but better safe than sorry, if you'll sleep better tonight!

I wouldn't worry

We are getting about a foot of snow tonight. The thought of it being a problem seems very remote to me. Roof loads in Minnesota buildings by code have to hold 40 lbs per sf. That's a lot of load and I doubt, other than snow drifting, the loads ever reached that in Minnesota. There is no snow drifting on an Airstream roof.

Dick, How cold does it get in Minnesota? I think Embarass Minnesota got down to over -60 a few years ago. I live in a depression about 20 feet lower than our road and one winter I registered -43 when the weather bureau was claiming -32. I couldn't believe it so I went out and bought another thermometer to confirm it. It is going to get very cold later this week. I may have to wear a hat and gloves.

We live in North Central Minn & the other night it was neg 22, with wind chills to -45. That was inside the house, can't confirm the outside temps. I worked for a natural gas utility & in the 70's it was down to -52, now that was cold. Had to wear a parka inside the truck. While I have the "Little Gem" under a temp cover ( see photo's on another thread) whenever I see a snow load building I remove it, just for peace of mind. Daveydd if you travel North 169 towards Mille Lacs lake on the West side are several bldgs that gave in to snow loads several years ago when we had that mega storm.
Best,

Well, the new coaches do have some tinting to them in the glass, so sunlight isn't really a problem, but the single pane does let loose some serious cold stuff!

I didn't know that about fiberglass. Good to know when I do my garage project.

Me, I worry more about bird droppings than 4"-8" of snow. Still I do take some off when I can just so I sleep a bit better at night too!

Collapsed roofs

Generally if a roof collapses it is because the drainage system gets clogged and melting water accumulates to the point of failure. Also, if snow drifiting is not accounted for (over and above the uniform design live load) a failure could occur as well. And then there are some buildings that never really met the code or were modified over the years with additional loads. It doesn't hurt to remove as much snow as possible when the snowfall is extraordinary. Duluth, MN got 28" in this storm. They may have some failures.

But, again, I would not worry about an Airstream. The Rocky Mountain states get much more snow. Were there any Airstream failures when Buffalo, NY got that 8 foot dump?

As an aside, the skylights over Camp Snoopy at the Mall of America were designed to carry over 80 lbs of snow load, not because they felt it was needed, but because they did not want even the very minor percentage of glass failure that statistically could occur at code load.

If 100 of us get up on ladders somebody is going to get hurt. I suspect we'll get more northerners providing their feedback this evening...
Hey!
do you think that equation can be applied proportionally to the popularity of LUTEFISK??

Cool, Norby. Cool. Lutefisk is nothing but dried codfish. Not that a cod is purdy, but a freshwater cod relative causes more turned stomachs up here -- the ugly eelpout. 'Specially when you were looking to pull up a walleye. It looks like you can still make your reservations! http://www.poutfest.com/


Dick, I've been aware of your Minnesota saga. I got my Argosy out of Laurel, DE. Small world! Yes, it has all the character issues of an older trailer but looks to be what I was seeking. I'm handy but didn't want to have to fix up, then decorate on top of it -- the inside is in well kept condition. The rest is a topic for another day I guess.

Stay warm y'all!!

They're infamous for wrapping their tail around anything in sight when you get 'em out of the water.

Ya nail the snout to a board, make a slice around behind the gills, then pull back the non-scaly skin with pliers to expose the meat which you then remove....

(note to self: good, I've gotten his mind outa the lutefisk track)

Eelpout

I think I will paint the top of my Tradewind with white paint.

IF I EVER SEE IT AGAIN!

Smile Looks familiar

A lot of snow and cold temperatures to keep it around (and on top).

I solved my snow loading problem by driving South 950 miles.
