Hello everyone! I've just noticed a tile out of place on my roof, on a single story part of my house. It's not a flat roof. I climbed up and was able to push the tile back into place but there seems to be a lot of loose tiles up there. I assume this isn't normal and you shouldn't be able to move them by hand? What would be the best thing to do? - Can I just repair it myself by putting some kind of cement on there or should I get a roofer in? The problem is now I don't know whether these loose tiles are just a one off or if there are others on the main roof. The house is only 10 years old. Thanks for any help!
