2nd question: What is the best way to fix all those ---- holes.
Already proposed:
A. Nail up a 2X2 under the errant holes using screws to plug the holes.
B. Cut up a bunch of Lexan 1/2" squares and glue them over the holes (IPS weld-on #3?)
C. Buy 44 16' sheets of new Lexan.
D. Use clear silicone to fill the holes (not sure if it's compatible with polycarbonate or if it will will stand up to UV/water over time).

Looked at your drawing. That is a pretty easy roof to work on, appears to be about 30 degree slope. Most roofers would not even stage that with roof jacks / planks. Just stand and walk around. Roof jacks are little triangle adjustment critters that allow putting temporary staging planks on a roof in the immediate work area that progressively move as work is done. Probably not totally necessary here.
My assumption:
You have this Lexan in long sheets, so-so wide. You don't attempt to get "
ON it. Basically would work to the side of it, to place and fasten. Typically work right to left, assuming most workers are right handed. You stand with feet on roof, lean over Lexan to work, never put your full weight on it, plus probably is slippery. Similar to installing metal roofing. You work to the side of the material itself.
Most local building dept's will require that a roofer "Stage a roof" to provide a safety platform to catch any worker that slips or falls. Can be done using standard pump jacks / platform with usually a ladder laid / tied to upper wing to give the safety rope / barrier. Usually this is positioned within 12" of the gutter. Also can be done with ladder jacks. Many roofers don't do it and many inspectors are lax in enforcement. Common sense says do it you are inexperienced, basically are building an area to allow any material / worker to slide onto and safely stop if they fall. Plus makes getting materials on to the roof itself easier.
One hazard in your case is probably wind. Large sheets of anything are tricky to handle in a breeze on a roof.
Would think this project is well within a rookie ability. If you know how it should be done, not much skill required on this particular roof. I might also consider collar ties right under the ridge beam and maybe a bit further down. Pretty good span there, you probably have no snow load to worry about but maybe can get some higher winds.
The usual drawback to a non-roofer is the specialized equipment / materials required to stage a roof. Probably not that revelant here.
As to #2, some method that is more permanent. I like that idea of using Lexan bits with some sort of glue / weld material that makes a permanent bond. A filter is probably going to fail at some point in the future.
I lived a couple years in Hawaii while in the Navy. Sorry I am not available to help you out. Be nice to get out of this ---- snow. Had more today.
