- Who flashes the mounts, and who is liable if a penetration leaks later?
- Does the mounting hardware affect the roofing manufacturer's warranty?
- If the roof needs replacing later, what does taking the array off and putting it back cost? Removal and reinstall pricing
- Are you doing both trades, or coordinating with a separate solar company?
