Cool Roofs in winter


Hi,

Does anyone know how much colder a house will be in the winter, with the new cool roof shingles? I'm in Southern California, and I already pay a lot for heating bills.

Thank you!

these reflect sunlight to get the performance touted. But in the winter the sun is at more of an angle and not much gain will be realized.

It all depends on the construction details of your home.

Like what details? It's a single story, with a low slope roof. Fiberglass insulation was blown into the attic many years ago. There's an add-on of 300 sq ft that won't have shingles, and which doesn't have an attic since it's too flat.

Everyone comments how weird it is that my house stays so cool in the summer -- I've never needed A/C. I currently have three layers of old tar and gravel roofing. I'm concerned that if I replace them with a single layer of shingles, the house will be too hot -- but I also don't want it to be any colder than it is now, in the winters. I barely stay warm enough as it is.

Are there any layers of rooftop insulation within these layers of old tar and gravel roofing?

AaronB, I don't know. Is there a way to tell without tearing the roof off?
