Does the concrete tile crack after long exposure to the sun? Any special advantages of using concrete tile versus clay tile? Does it discolor after long period of time?

Concrete tile does not crack from long term exposure to the sun. Some of the advantages of concrete tile over clay tile are the greater color and profile selection, lower installed cost and better walkability. Roof tiles are subject to a certain amount of oxidation and surface erosion that will result in some appearance change over time but the degree of change will depend on which type of tile is selected and the climate conditions where it is installed. I have a 3 year old Lifetile roof and am now going to paint the house. Please advise best way to prevent breakage while accessing upper parts of the walls requiring climbing on the roof. Most of the pitch is 5 on 12. The most common method used by trades people who perform rooftop work is to place walking boards on the roof that will effectively cushion the impact of foot traffic and spread the load over a number of tiles.  more
