Hot ceiling and roof and skylights
I have a 1950s triplex building with a flat roof, no attic and no insulation. The units get very hot in the summer, even though it's near the beach. I plan to have the old single pane skylights switched to dual pane. Should I do the expensive velux glass with solar remote opening, or the dual acryclic dome? And I've heard painting the roof with a white reflective paint will cut heat. anyone try this?
The roof is only 4 -5 years old. Thanks
