I have given up finding a contractor to properly install the barrel tiles on my roof, so I am going to try and do it myself. Does anyone know if Tile Bond type roof tile adhesive is available in Cancun. It is a polyurathane adhesive foam that comes in small cans or cylinders. Has anyone seen this used, or know of anyone who uses it to apply tiles? I want to get this done before we are into the most active part of hurricane season. About half of the tiles replaced after Wilma are now loose and will become missles in another storm.
