Are our cracked roofing tiles dangerous?
The tiles provide protection to the water proof barriers below it. A chipped tile isn't dangerous if it's still secured to the roof with the mortar or foam adhesives they used today. If it's not secure, it could slip out while you're walking on it and you could fall. Walking on lose tiles could damage the layers below, causing leaks. The chipping or broken tiles usually are caused by people walking on them and stepping close to the tile edges. If you have a pieces, there are many types of roof tile adhesives that match roof tiles and you can reattach the pieces. If whole tiles are broken, you might be able to find replacement tiles. If not, you can get some tile mortar and rebuild the tiles. Throw on some matching paint and you're good to go.
