Replace 20 yr old Skylights?
We are having a new roof put on next month. We currently have two layers of shingles, so they'll both be taken off down to the decking. We currently have two Andersen skylights aboe the sunroom. I'm assuming they are at least 20 yrs old. Probably closer to 25. They don't seem to leak. At least not in the past 3.5 years we have lived there. There are some water stains, but I think the previous owners left them open on a few occasions.
I got up on the roof last week and wiped the glass down with windex, and I noticed that the metal tabs between the two panes of glass are rusted and flaking. I'm assuming some condensation gets between the glass.
Would you replace the skylight now???
I'm thinking of going with Velux Fixed skylights
Thanks for your adice!
