said by ke4pym:It's the ones around the cells you will have to address. Are you planning on just replacing those and leaving the shingles under the cells? Even if it is touted as being a 30 year roof we all know how that works out. said by Jack_in_VA:
It will be sooner than that. Your roof will need replacing before then and the panels will have to be removed. 25 years is a stretch for a shingled roof.
Just put a brand new, 30 year roof on last Tuesday. See you in 24 years, 6 months
The shingles under the panels outta last a WHOLE lot longer since the sun will never shine on them.
