While here, I pointed out my construction techniques on my porch, and he thought it looked pretty good. He did have one caveat though - if it had been him building it, he would have doubled up the supports at the outside edge of the porch roof.
This was something that I had originally put into my plans. I even told myself that I would add this in the fall/winter when there was an actual snow load on the roof. At the moment though, I'm not sure if I want to add this to the monetary or time budget. Instead, I opted for another solution that just involved routine maintenance... Keeping most of the snow clear!
Previously, I had used a long branch that Grandpa had rigged up with the end of an old gravel rake and a small piece of plywood wired to it. This worked passably to clear snow from the dojo tent and the outside edges of the sauna porch roof, until it self-destructed.
I spend the remainder of the winter poking the dojo tent roof and yurt roof from underneath - VERY challenging work! My shoulders were screaming by the end. Then I stood on a step ladder and tried to use a snowshovel to clear snow from off of the sauna roof. Not very safe (I recall actually falling off into the snow), and not very effective. I wasn't willing to actually step up on the roof with the snow there too, and no real, permanent supports in place.
In any case, this year I decided to bite the bullet and purchase one of those "angled snow shovels for pulling snow off the roof" - which it turns out has its' own name - a "Roof Rake".
I looked at pricing in the area; all were between $43.00 and $50.00. Most of them had about 5' or 6' segments that you clicked together to get the length you desired. Canadian Tire had a version with a telescopic pole that caught my eye, and it also was apparently better because the tube had an oval profile, which should lend it greater transverse strength.
I purchased that one, at about $46.00. It was relatively easy to assemble, and actually using it was such a joy! I was stunned with the ease of use and effectiveness. I would certainly recommend one to anyone who has similar needs.
My greatest regret is that I didn't buy it the first winter. It would surely have prevented the collapse of the dojo tent - a tough, time-consuming tragedy. I can say it has a real use here on our particular homestead.
