Convert square old-school skylight to solar tube?

Hi there,

We bought a 1978 tri-level in Seattle in April. It has 2 old school skylights, one above the stairs to the top floor and one in my son's room (also on the top floor). That skylight goes through the top attic whereas, I believe the one above the stairs goes straight into the roof. I know the one in my son's room leaks (we haven't observed it, but there is some water damage. Our home inspector said they needed to be sealed/properly framed out in our inspection report.

I was wondering if anyone knew if it was possible to convert these to solar tubes. The issue is that the largest solar tube I have found online was 21". The skylights are 21" square, but for that I would need an approximately 28" circle. Is it possible to patch that spot on the roof and then do a circular opening of an appropriate size, or should I just try to reseal/update these uber-dated skylights?

Is your tri level a town home or condo that pays dues? If so, exterior issues are typically handled by an associative group. The skylights should be at least resealed to prevent further moisture damage. A concern is that framing may be an issue! This suggests that the skylights were not installed properly and may be a larger problem. I would recommend having a skylight installer look at the skylights for best options.
