Roof Flashing Leaks

Roof leaks can happen in the center of a roof, but they usually don't. Roof leaks happen where the roof touches up against non-roofing materials such as walls or chimneys. Metal flashings protect water from leaking into these intersections. Caulk is not a replacement for these flashings.

Efflorescence Causes

Efflorescence, white stains, can occur on brick, masonry and concrete. They are caused by salts that are in the brick and mortar or are transferred into the masonry by water. This salt can even be in the dirt used to backfill these walls. When the water evaporates, the salt comes to the surface and dries there. Removal can be difficult.
