Are white shingles really cooler?

rosemintSeptember 11, 2010

Hello,

I hope this is the right forum for this question.

I'm replacing a white tar and gravel roof with 30-year Gaf Timberline shingles. I'm deciding between "aspen white" and "hickory." Does anyone know if the house itself

will feel significantly hotter with the darker color?

I live in Southern California, but don't have central A/C. I haven't needed it up til now.

Thanks!

It depends on the exposure of the roof and how much insulation is in it but the surface of the roof will definitely be cooler. In a well insulated house in a moderate climate, white shingles will probably have more effect on the lifespan of the shingles than on the temperature of the interior spaces and the quality of the shingles will have more effect on the lifespan than color.

You are replacing a flat roof with a slanted shingle roof?

If that is what you are doing, adding a sufficient amount of insulation in the new attic space will be more efficient that any shingle color.

Thanks, Macv and handymac!

Yes, we're replacing the flat roof with a slanted roof.
There's enough pitch for it.
