SanteFe, I am taling about putting solar on an existing roof, say 5 years later a new roof is needed, Many panels must be removed to get at the shingles to tear them off, repaper and reshingle. The cost of removing panels and putting them back could be double the installation time of first putting them and the roofers help might damage some of the panels and be liable any maybe five years after installation, those same panels are not made anymore. Again, the hiden cost of a very expensive new roof could be huge.
