I am looking at leaks on a front door canopy, and wondering what the pro solution is? The problem came from bad placement/alignment for the eave tiles. Here's the rough layout of the tiles. I am guessing on the bits that are not normally visible externally. Blue: concrete tiles. Black: first row of tiles. Yellow: eave tiles. Red: locations of leaks. The tiles on the side edge of the canopy are mortared in place. How the other tiles are fixed I don't know. How do I find out? Thanks.
