A roofer friend told me the life expectancy on the solar panels being installed isn't even going to be the 20 years without vigorous maintenance. He will not take roofing jobs that have the panels because the labor and risk is just too large. The normal heat and cool cycle will deteriorate the roof around the installation brackets and then people get a leaky roof around the mounts which will cause enough damage before it's noticed to demand new shingles and decking. Then the panels have to be removed without damage and reattached. He says the risk just isn't worth it.
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.
And they prolly wont last that long in hot climates, like Phoenix. The sun will eventually warp and destroy the panels, just like it does on those those solar powered outdoor Malibu lights.
