I believe the roof is a modified bitumen. The skylight appears to be a cheapo acrylic. It’s not too big; I measured 16x16 from the inside.
I’ll probably replace the entire roof within the next few years. I might even cover up the skylight at that time. I haven’t decided yet.
What are my options? Do they just sell the acrylic panel, or do I need to replace the entire skylight? I’m thinking it sits on a curb, but I couldn’t get on the roof due to the rain. Do they still sell cheap single pane skylights?
