Working on a 10/12 pitch asphalt shingle roof

steep 10/12 pitch roof

Time and Patience needed when working a steep roof like this!

Rich's climbing skills were priceless during the initial stages of the installation

Oh my goodness!!! The pictures looked like a nice easy 6/12. When I got up on the roof I IMMEDIATELY realized it was more like 10/12. That’s JUST SHY OF 45 DEGREE SLOPE! Almost perfect for our 39 degree latitude in the Cincinnati area, but NOT MUCH FUN to get started.

We set 90 feet each with two 3 1/2 inch lag bolts and a 3 inch spacer (Unirac-I product) and that took from 8AM till 1:30 PM. The feet made navigating the roof much easier, since there were at least some footholds to stop from sliding. Of course, I had my OHSA approved harness and rope line on. It was like cliff climbing!! We managed to get two panels in two rows on a small shade room addition mounted as an instruction area before having all the helpers tackle the 10/12 pitch roof!!

I wasn’t about to go up/down any more than I needed to, so I didn’t get any pictures today, but I’ll be back to finish the job tomorrow, and I’ll come home with some spectacular pics to add to this section!!

17 panels on the 10/12 pitch; one row of five, one row of seven, and the bottom row is five in landscape style to fit the trapezoidal roof section. One row of five panels on each side of a 3/12 pitch shade room roof facing north south, but still exposed to LOTS of sun.

NOT A TREE BLOCKING THE SUN FROM ANY DIRECTION!! This guy will make MULTI-MEGAWATTS of solar power! See ya’ll tomorrow when I get back!

FInished installation 17 panels on main and 10 panels on sub roof. 6345 watts!

  1. Joe is officially the man! He will get panels on your house… You should hire him and save tons of $$$ if you don’t mind doing some work yourself. He will give you everything you need and help you through the entire process… THANK YOU JOE!!!!

    • 6/12 is about the limit for normal unassisted (roof jacks) work. Always wear a harness! WATCH where you are stepping once you get feet and rails installed. The chance of accidents increases as roof pitch goes up. I think there’s a garage roof in the blog with a 6/12 pitch.
