Valley leaks
Where two roof slopes meet
A chimney can let water in without the roof being involved at all. A cracked crown, a missing cap, spalled brick or eroded mortar joints all admit water into the stack, where it travels down and appears inside looking exactly like a roof leak. Because the symptom is identical, chimneys are a common source of leaks that have been repaired at roof level more than once without success.
Dallas sits in one of the most active hail corridors in the country, and hail is the roof killer here in a way that is easy to underestimate. The stone rarely punches through a shingle. It bruises the asphalt mat beneath the granule surface, leaving a soft spot that sheds water for another season or two and then fails — which is why a leak in Dallas County so often traces back to a storm the owner had stopped thinking about. Insurers know the pattern and scrutinise the gap between storm date and claim, so the roofs that get paid for are the ones that were documented when the hail fell rather than when the ceiling stained. Wind arrives with the same systems and does the quieter damage: lifting tabs, breaking the seal strip underneath, and leaving a roof that looks untouched from the driveway.
Dallas has a population of about 1,329,491, and the housing stock here sets the pattern for what fails first on a roof.
Both present almost identically. Flashing leaks usually show at ceiling level where the stack passes through; masonry leaks often show lower, on the breast itself, and worsen with wind-driven rain from a particular direction. Checking both before working on either saves repeating the job.
More so, arguably. An open flue on a disused stack takes rain straight into the structure with nothing drawing it back out, so the masonry stays wet and deteriorates faster than one in use.
