Water Stains On Your Ceiling?

If you are seeing water stains on your ceilings near your fireplace, it may be because your flashing wasn't cut into the masonry above, (or laid into the mortar by your masons), and the caulk needs replacing because it is allowing water behind the flashing.

To prevent having this maintenance job to perform frequently, you can cut a 1 inch deep grove into the masonry, fill it with a good caulk, and then drive a piece of flashing with a V at the top overlapping your base flashing.

Overlap and caulk the edges, and the situation should improve. As you can see from the side view of the flashing, the top of the V is shorter, so if water does make it's way into the grove, it can't get over the top of the V.
