I own a flat roofed row how that gets extremely hot in the summer. I have been advised to install attic vents on my roof. I am having trouble figuring out which product would be best: 1) a solar powered vent fan by Solatube that costs about $550 each 2) wind driven ventilator , which is about $100 each 3) or a solar/wind combination ventilator. My concern is that the solar-powered fan will only work during the day and when the sun goes down the attic will begin to heat up again. Any advice would be most helpful.

  1. Attic heat builds up primarily during the day so a solar fan matches that. How well it works I couldn’t research when I was thinking of installing one. It’s also much more expensive than a regular fan (but that would require an electric line, so maybe it’s a wash). Also, check how well it runs on cloudy days (because it can still be hot)
