Homeower roof anchor for fall restraint needed.
 
Every year I need to remove large amounts of snow off my roof. This year was 41" deep in a few spots. Also to clean tree debris, inspections, repairs, etc.

I am on the roof often enough.

I DO tie off to secure ground structures on the opposite side of the roof area I am working on. I work for an arborist and am highly proficient with harness systems and TREE heights.

I am looking for a more permanent central anchor for rooftop attachment.

Can the "roofer" homedepot ridge anchors be left installed? Or any other ideas that require minimal alteration to the roof itself?

Ok so you get one mounted up there, then what, leave a rope hanging from it so you do not have to climb up to attach the rope and harness each time you need it?
I've never seen one that's meant to be left in place and would be a sure way to have a roof leak.
Concider something like one of these.

Run a taunt cable from gable to gable at the ridge line. Then hook your fall restraint line to that

Seen roofers do it many times with the temporary anchors, crawl up there then nail the thing in place, then hook in. I was hoping bolting it in place and sealin it would be a suitable permanent life attachment point.

Right now I pull the whole rope over the house with a throwline, not too bad but kinda a pita.

Now that I think of it, would have to find the anchor under the snow first.

back to the drawing board...

Can not recommend but I have tied into many one those old satellite dish mounts. They have all been very strong.

Miller makes permanent stainless steel anchors, that are installed under the ridge caps, the D rings hang underneath. I believe they were $60-70 last time I bought one.
If your uncomfortable walking it until your tied off, look into a hook ladder. Hook it on the ridge, climb up and tie off.

I think Eplumber has it nailed. A 1/2 inch forged Eye bolt through bolted to the structure at the ends of the ridge, and possibly one in the middle. Then a 3/8 inch galvanized or stainless wire rope stretched between with three clamps on each end. You could then use a pulley to run along the wire rope (Like a dog run) You could leave a small diameter UV resistant rope through the pully as a lead line to pull your heavy line through when you want to go up slope.

Hook ladder does not perform well with snow, tried. Think I will look into an under shingle Dring style. For now will still toss the rope, need the practice anyway for trees.
