Had someone stop today and wanted to know I needed my roof shoveled. I said no, as I've got a roof rake, and used it quite a bit before I had my roof fixed. I figure there is a good foot up there, and I have one section which is shallow at 30 degrees. More in the forecast, so perhaps it would be good to pull some down? Taking care to not nick any shingles, of course.

Roof rake? Interesting. Never thought about it. Good for the second story? Do it out the windows or from the ground?
Probably good practice no matter what the forecast or where you live...

A 12 pitch, as the roofers call them, shouldnt hold snow very well.

Nor any roofers.

I find it holds snow quite well. I didn't think to take a pic, but certainly is getting deep up there. This is an old pic, and you can see that I removed from the right side, but left side still has snow. I'd say I have more than that up there, close to a foot.

With the low water content snows we have been receiving, there shouldn't be much of a load.
The the rain to snow ratio is like 0.03.

The only time I've seen a snow load that concerned me was at work. We have a flat roof and the snow had built-up on it due to wind conditions. Then the rain came. The snow absorbed the rain and it got quite heavy up there. Typical small plant construction, the walls supported by the floor (of course) and the ceiling is hung from the roofing system. With this construction you could see the roof deflection where the ceiling panels met the walls. In some places it was obvious the roof was deflecting downward 1 to 2 inches. That did spook me...
I roof rake usually only the lower couple feet to help minimize ice dam potential, but if we get a lot of snow I rake as high as I can. I have 3 extensions for a total of about 16+ feet. Problem is my shingles have taken a beating from the scraping action and I'd like to put some skids on the bottom of the rake. If it rains onto a foot of snow then the snow will be very heavy so I like to rake before that happens. Also if you only have one layer of shingles then you have more capacity for added weight on the roof.
