A roof has a 25-30 year life expectancy, so occasionally a roof replacement may be required to install panels. In these situations the Federal ITC can be applied to the cost of the roof as well as the panels if they are done as the same project. By offering roofing services only for our solar customers, we are able to do the jobs at-cost with no upcharge offering you the lowest possible option for the quality, even before considering your ITC.
