I’ve seen flat roofs with 18″ tile and after walking on it I thought it was a great idea. I think the family was from Russia or Ukrainian.
Topped off some trees in the neighbors yard today, after getting their permission (was partly shading the garage roof). It is really pretty easy to do if you make the cuts in the right place. I’ve trimmed trees before, but now I know the secret to make it easy. Every time I try something new I consider changing careers, but only for a few minutes.
To get the state rebate I think one has to prove shading is not an issue, at least to get the full credit.
