Solar nuances and hopefully a free (or discounted) roof?

[Nash Mittelman]

Hi BP! 

Getting to the end of my roof's lifespan, and was wondering fi there were any programs or partnerships that I should be aware of if I were was to add solar whilst replacing my roof? I heard there used to be programs where the solar companies would actually replace the roof for you when adding solar?

I have a duplex so also curious about the nuances of adding solar to a home that I currently live in, but might turn into a rental, or sell down the line?

Thx BP!
