Had actually been wondering if the very problem you discuss (Bearhouse) was a factor in roof longevity... that’s definitely concerning and makes be wonder if anyone has come up with a means to overcome it.
Tell It Right — I’m actually with you on your points: my aim was to do a bit of a lampoon against the Press Sec’s stupidity (and yes, I included a full-on roof replacement with that 20 yr. swag), but I have been considering whether a retirement monies withdraw might be well spent in this direction... it avoids loans, reduces monthlies, and avoid the TVA’s eye-popping price increases.
Certainly no instant payoff, though... that much is certain.
Even with that, solar on the roof is worth consideration only if you don't have good land for a solar array. I'd pick ground based over roof based if it didn't mean cutting down a bunch of trees. There are other considerations before going solar too, like if both you and your spouse work (which means little electricity consumed during the day when the sun is out, thus you need more battery storage and inverter strength to power all the appliances you run all at once after office hours), if your area gets good sunlight, if your area tends to have sunny days during the temperature extreme days, etc. And even if solar is good for you, I'd first spend money on other energy improvements like better insulation, caulking cracks, and replacing old appliances with more efficient ones (though if you do the latter it's best to have solar and inverters in mind when picking the appliances so you can do things like power them by solar alone when possible, especially if the grid power is down). Then there are other things like if you're going to charge an EV, what times of day you'd normally charge it, and if your normal EV use will let you get by without charging it for a few days if there's no sun (I charge mine with solar only if the EV has at least 100 miles left on the charge and we have no plans out-of-town getaway).
