Is DIY repair pool solar heater is a doable option?

Have a more than 10-year-old rooftop solar heater system, and hasn't run it for several seasons due to leaking. Recently I have started to think of repairing it. Ran it and found the following problems;

1) 4 or 5 Fafco collector panels (4'x10'x12") leak (9 in total), highly suspect racoons or squirrels bite them or the rubber is too old, they need to be replaced
2) Several valve stem O-rings leak, need to replace
3) some pipes have turned white, need to be repainted to black.

Pipes and valves seem all work properly.

Consulted a contractor who said it took $6000 to repair, which is a big money for me. I wonder if it can be DIYed within an economic budget. Will the repair require special equipment and tools, and whether if it includes any dangerous part or would damage something if not done correctly. Any online resources to explain how to do this job?

If answers go negative I'd have to find a contractor to do it.

Thanks.

The big problem will be finding Fafco replacement panels. Will the local distributor sell you panels?

There is nothing magic to the system. You need to make yourself familiar with how its put together and how to safely work on a roof. Its the roof work that is tough.

Solar Direct sells replacement panels, hardware and I'm pretty sure they sell leak repair kits too. Fafco 4x10 Solar Pool Heating Panels

When my panels have leaked it has been the rubber connector hoses and hose clamps. They move a bit during winter and need to be tightened back up. I have fixed a couple of leaks cheap and easy so far. But, 10 years is what folks say is the lifespan of solar panels so maybe it is time for some new panels.
