A roof that exceeds 10% of the purchase price is likely to push the house outside of the price range of buyers in the target market.

I know a friend of mine (who has a solar system, not quite the same) but basically got almost nothing for it. The aesthetics of a "Solar Roof" is better but I don't see it raising the value of the house by more than 10%.

I used their calculator using the estimates when I had my roof done last time, and it is just not economically feasible.

$60k roof vs. $6k roof.

Net of $12k savings over 30 years.

$60k over 30 years (adjusting for inflation in conservative investments) is easily going to hit $180k.
