Leaking skylight repair advice
I live in Zone 4a and the pic below shows a skylight on the roof of my neighbor’s house. It leaks when it rains.
We are trying to buy him some time.
We used some “through the roof” on flat areas around the skylight, over the tar; however, I think it is leaking through a dry rotted gasket where glass meets metal.
This was tarred over some years back as seen in pic. I thought to put some “through the roof” around the frame and onto the glass and tar along the edge: but, “through the roof” is not good for puddle locations/submersion and that is the reality at the bottom edge of the skylight/glass panel 1/2″ deep puddle which can last for several days at a time in this location.
I had considered a good sealant, but, the ability to adhere to tar, glass, and metal is an important quality it would need.
Thanks for any advice.
