The house I bought earlier this year had a failing roof and defunct solar pool heater. I'm planning to replace both this year. This puts me in the semi-unusual position of being able to plan for the solar system while having the roof re-done. So I'm wondering if anybody has any tips or advice. I'm mostly interested in whether any roofing systems are more conducive to solar pool heaters, and whether there's anything I can do when doing the roof to reduce the chance of roof leaks (e.g. somehow minimize roof penetrations needed for the solar).
FYI- I have a low-pitch roof (2:12) and am currently considering a torch down, PVC, or standing seam metal roof.
I'm fascinated by the idea that a metal roof allows you to clamp onto the seams for securing things, which means no roof penetrations. I know people install PV panels this way, but I don't know if it'd be suitable for the pool heater panels / headers. Anybody know?
Anyway, if anybody happens to have any insights / tips, I'd appreciate it. I'm fairly new to roofs, pools, and solar.
