Recently Insulated --- Now too hot!
Hmmm. Thanks for the info. In my particular case it is an old rowhome with a flat roof and there are not now nor have there ever been vents. Guess that wasn't how they built the 75 years ago. So, I'd imagine without the insulation the roof breathed better, no? Interesting to know that it could cause the problem.
So, how does one vent a flat roof? I am guessing a mechanical vent of some sort, perhaps solar powered? Any recomendations? How big? And the most important question, how can I install it without welcoming leaks. My roof is covered with rolled asphalt material. I will replace the roof eventually, but would love to solve the problem sooner rather than later. Any thoughts?
