Hi- Due to a poorly installed solar panel system on my roof (1950's suburban ranch; deck is ~1x4 pine slats- common for the period; recent architectural asphalt shingles within 15yrs; new york), the panels and tracks and electrical fittings must be removed in order for the shingles and membrane to be removed and replaced. (The roof started leaking a few months after installation- now there are 5 leaks). There are already numerous 'patched' penetrations made by the original solar panel installers from 1) when they made an error and mounted the panel tracks in the wrong place: 3/8" lag bolts were screwed into rafters.. several missed their target, and 2) when they cut 2" holes for electrical cable/ fittings. I'm trying to get the installation company to cover the cost of the reroofing job and am wondering if the entire roof area is going to need to be re-sheathed, or what the best way is to patch the holes made for electrical openings and the lag bolt penetrations. Thanks in advance. Jeff
