looks really great and is supposed to be cheaper over the long term, though it's initially more expensive than other roofing

After researching on the EPA's Energy Star web site, we went with white CertainTeed Energy-Star rated asphalt shingles, which got us an $800 tax deduction. The roofer also put in soffitt vents and a type of ridge vent to keep our attic cooler, and put in new gutters and leaf guards. We think he did a fantastic job.

I will PM you the name of the roofer we worked with, because he is excellent and had very good prices and workmanship. I got estimates from 6 roofers and he was by far the best. My neighbor across the street also had his roof redone by the same company.

and that it doubles the cost

I remember that I wasn't particularly p'o'ed when he said that. LOL

So we get a lot of hot sun. The shade trees are in the back yard. That's why I wanted something that would help reflect the light.

If we can ever afford it, I want to put up some kind of solar panls.

In two different houses, I've replaced those thin, single layer three tab shingles with architectural shingles that have two layers. Add a ridge vent, taking out whirly-gigs, and you're good to go.

in pewter gray or biscayne blue (I think the blue is too light, or I'd have it in a minute)

What do you think?

It ain't just for barns anymore. Although it is VERY nice on a barn

still looks brand new

. . . . very possible.

The "paint" on it is a very high tech coating. The biggest threat to it is abrasion, which is almost impossible to experience except in a sandstorm!

just saying...... Arizona blows and Texas sucks and i'm in the middle

Another beauty about them is that they can, indeed, be recoated. But where you are, they will probably last uncoated.
