We have a terracotta cement tile roof and the tiles are the same color, though and through. It's 13 years old and looks brand new. Here in FL, we have it cleaned each year because of algae growth from all the rain.

Beachlily,
Good to know! We are able to go with Mextile cement at no cost or upgrade to clay. The colors we like look very similar to clay but we were concerned that the deep south sun will fade them and cause us to regret not upgrading.

Here is a link that might be useful:

i went with clay tiles mainly because most of the houses in my neighborhood are clay tile. the concrete does look a little different-- mainly the texture is not as smooth. color-wise, the roofing salesmen told us that the concrete tiles of today are much better than before so the fading is not as bad. but i have heard that if you have a roof repair further down the line, it is easier to match new clay tiles to the old tiles than new concrete tiles. HTH!
