I'm in Florida too.
I opted against tesla roof because it cost quite a bit more than shingle. And insurance companies tend to start jacking up rates as you approach 17 years of roof age. So even if tesla roof lasts longer than shingle, it might not be cost effective to keep it that long.
I opted against powerwall because I have net metering, so no cost savings with time shifting power consumption. The cost of the powerwall would be just for UPS backup and it's not worth anywhere near that amount to me. If I wanted standby power, a NG generator would cost less and have unlimited runtime without needing sun to recharge. If I ever NEEDED backup power, it would be because of a hurricane and extended power outage (longer than 2 days), which has yet to happen to me and I've been in the state since 1999. To store the excess power generation that can't go to the grid, I'd need at least 4 power walls. The cost of a NG generator would be at least half the price.
I bought a 17kw system + new roof for ~60k before incentives this Feb. My roof is over 5000 sq ft of shingles - covered area over pool cage and over garage too, so my roof only estimates were anywhere from 18k to 30k when I shopped. Panels are panasonic N330 with 25 years on both panels and enphase microinverters. Roof has 20 year workmanship and 50 year product guarantee. Tesla's current PV pricing is a bit less now than in Feb (actually lower than I paid for solar), but I don't regard their new solar panel mfg as highly as panasonic, and their inverters don't carry 25 year warranty anymore either. With their new lower pricing, if I were in the market, I'd strongly look at their PV offerings despite the lesser panel and warranty. It could well be worth it, but I'm happy with what I have installed. I've heard some people had luck asking for Panasonic panels as an optional upgrade. Guess that depends on what they have in stock.
PS: There is zero chance the new tesla roof adds 100k value to the home. By the time you sell, the prices will have dropped, and your stuff is older and will generate less efficiently. Your batteries will have degradation, etc. Even less if the old panels end up with a bad reputation due to longevity or other issues. Also consider what happens if Tesla goes bankrupt or sells off the solar portion of the business.
I would mostly value solar around 50-70% or so of the monthly power reduction multiplied by the expected roof lifespan remaining to get a value proposition for the house. Reason for the discount is that if the home didn't have it, the owner could install and pick quality, size, etc. And there is a fairly large cost involved with removing and reinstalling solar, so whenever the roof is redone, the solar becomes a headache they wouldn't have otherwise had. Using this logic, any PV system is more valuable than the tesla roof as tesla roof costs more per kw than PV. If you gain additional value above and beyond the power generation would only matter if the buyer REALLY liked tesla roof and other buyers in the market likewise were willing to pay more for it. This seems unlikely. Most people really only care that the roof is functional and isn't leaking.
PPS: Your ROI should factor in the solar portion only. Your house always needs a roof. There is never a payback period on it. It just depreciates. So if you go with tesla roof, subtract what a traditional roof would have cost from the price, and then figure your ROI on the remaining amount. Personally I'd also subtract the powerwall too, as it doesn't generate savings (unless you have time of use rates)
