Josh from Corona, CA asked:
I have numerous broken flat concrete tiles on my roof. The currently installed tiles are Monier and have had a hard time trying to locate replacements, and when I have been able to find them, they are very expensive. I am going to buy replacement tiles that are not a match. I know I need to replace an entire row with the different type, but where do I install them? As a top row? Any information would be greatly appreciated.
