Load not a problem. Some jurisdictions actually "legal" from research I did. Easy fix though. I called the local county code office and roof requires a tear-off to wood slats. I have called for a complete tear-off (to the rafters). Contractor still wanted to fight me on it so I ordered a code inspection for tomorrow morning. Man is he going to have a bad day. (-;

Thanks for the feedback.

P.S. This is same guy who reduced 4" DWV in home to 3" and had four 90 degree bends on pipe between were it left crawlspace to septic tank! That would have to be some agile t*rds to get around those bends without clogging. And inlet tee extended 3 feet into the tank! Blockage waiting to happen six ways to Sunday.

First home I personally inspected that actually had several layers of shingles installed over cedar shake roof. Learn something new every day. I love it.
