Best design for winter/snow
Posted 02 December 2012 - 07:55 AM
I plan on building a larger observatory, something around 10'x16' that can house 2 telescopes. With winter in mind, what is the best design?
I am thinking about a ROR. Just roll and observe. I lose some of the summer benefits of a roll-around/dome, but likely gain for winter.
Another option is the flip top version. I built one before as an 8'x8', but my new one will be around 10'x16'. I do not think this design would work due to the size.
Any ideas would be greatly appreciated, as well as experiences that did not work out that well.

Here in snow country, my main house roof is 12/12 metal, it usually dumps, the ell is 10/12, it sometimes dumps.....

If you do plan on the roof shedding snow be sure the entrance door is on one of the sides without a lot of snow pile-up.

That's probably a good idea to use metal roofing. They do shed snow nicely in our climate. I'm not as confident though about Canada, where days above freezing may be few and far between.
Doesn't have to be above freezing for the snow on a metal roof to start melting enough it will slide off, as long as it's a clear sunshiny day. If it's a very heavy snow, I will also use a pushbroom to get the majority of the heavy snow off; then it doesn't take much sun for the rest to start sliding off. Now, I'm not talking about cold below 20F.

Metal roofs are used all the time in Canada on home roofs. I used to have one on a previous home. The snow diffenitely comes off as the temp gets close to freezing, event on a 4/12 or 5/12 pitch. When the roof snow gets 3 feet deep, it comes off quick and you better not be under it!

Also, in warmer times dew has a tendency to drip off the roof onto the floor with this config. I have a couple of dedicated old beach towels I toss up on the edge of the roof to rectifiy when conditions call for. It is not really an issue.

A 10'x16' flip top would be very heavy regardless of construction materials used. I did play around with splitting a 10'x14' roof in half thus having two sections that could flip open on either side. The weight would be reduced and it would allow you to keep parts of the roof closed for wind/temp management. This is important when the temps drop to -20F. The middle section should seal well by overlapping the one section on top of the other. This is how the ends of the roof worked over the gables of my previous flip top and I never had an issue with weather getting into the observatory.

A 10x14 or 10x16 multiple flip top certainly puts my engineering skills to the test.

My warm room is a one-person space that is about the size of a tree-house I had as a kid (my first construction job).

Could you post a photo of your warm room? Thanks.

I enclosed an area that would be underneath of the ROR when the observatory is open. My observatory roof is split in the middle, so the enclosed area is 1/2 the obs area. At first, I was using this area as storage for my lawnmower, but when I got the hankering for a warmroom, I enclosed about 1/3 of it for the warm room. So the warm room is pretty tiny, about 1/6th the obs area, or 3 x 6 feet. More of a cubbyhole than a room (but warm!).

With a metal roof, it seems likely that a clever individual could create a de-icing system that would warm the roof to make snow and ice melt or otherwise slide off of it.
Care to speculate why there is no snow on my observatory roof? We have had more snow than usual this year. Most has been the heavy wet variety that sticks to everything.
No heating system in the roof either.
If an observatory roof was to be crushed by a snowfall I would tend to blame the builder for that problem not the snow.
By the way how deep is the snow in Alabama this winter, got enough for snowmobiling yet
