The bottom row of tiles on my roof are loose.Depending on the weather(wind) I have to move the tiles back every 3 weeks as they are slipping down.How do I fix this without ripping up all the tiles just to nail down this one row?I do not have a gutter.
If they are the newer cement tiles, I would try a small cement drill, about the size of a 16 penny nail. Try to gently drill a hole in the tile where you want to nail it to the roof. Or use screws that don't rust. Don't nail or screw down to the tile, that will break it. You just want the nail to hold the tile in position. If they are the older mission tiles, made of clay, the same might work. But they are very brittle and may need a wood support shaped the same as the tile to put under before drilling.................JJJ
Take a length of galvanized wire bend a hook on the end pass under fixed tile above the loose tile And turn to hook up at top Put loose tile back bend wire up at bottom to hold in place. It works with slates so should work with tiles
