Free Roof with Solar?

[Mariah Monson]

We just bought our first multifamily and it needs a new roof. We were able to get seller credit to help off-set the cost, but now we have heard of some people getting a free roof with the installation of solar. Obviously, most companies aren't advertising this openly. Does anyone have personal experience with this? Any recommendations would be appreciated. We know we'd still have to pay for the solar, but it'd be nice to get a two-for-one and pay over time rather than all at once.
