[Michael Welch]

Hi William. White roofs can be very effective. SMUD has an extensive white roofs program in Sacramento. Not only do they help cool an individual building, but in inner-city situations they can decrease ambient temperatures.

Nothing will match the weird comp shingles already on our roof, so we are going to not match and re-roof the rest of the house later.  In the meantime, I need to pick a shingle color.  How much difference does a lighter roof color make here in our inland California (Mediterranean) climate?  We get over 100F frequently in the summer.
