How do solar panels impact the cost of re-roofing?
I am not trying to be a kill-joy, but I am curious about how the complexity of roof-top solar panels impacts the cost of re-roofing.
Nearly all of the houses around here have asphalt shingles although steel roofs are becoming more popular for re-roofing. Asphalt shingles have a service life of 20-to-30 years if the roof is properly vented. Solar panels are usually considered to have a 25 year service life. I suppose one could try to synchronize their life-cycles, but what about the building owner who puts solar panels on a ten or fifteen year old roof?
