One thing i do suggest if the skylights are 10 years old i suggest replacing them.
How to replace a skylight on a metal roof.
Yes you can put skylights in a metal roof.
Even the best skylights have only a 20 year warranty.
Align the grooves on the skylight fins with the grooves on the corrugated roofing.
Place the skylight unit on the roof at the desired location.
Mark an outline along the outer edges of the fins.
Better to replace them now than in 5 years.
The good news is that if you are considering a metal roof for your business adding skylights is never out of the question.
