We had Roof Rejuvenate brand coating (not Roof Maxx). They first seal all penetrations on the roof with calk and they lay a thick coat of their product. It leaves a shine on plants and is not harmful. The grit loss off the roof immediately stopped. Yes, the idea is to maintain flexibility especially in a storm. It is more expensive than I expected but I’m happy with the results. My insurance company is Tower Hill. The product is known to them but too new to garner a discount. Tower Hill Exchange also pro-rates roof claims much like your car tire warranty, so their exposure is less and they have no 15-year limit.
