Valley leaks
Where two roof slopes meet
Flashing fails more often than shingles do, and the chimney is where it fails first. Masonry and roof framing move at different rates, which over years opens the joint where counter-flashing is set into the mortar. Step flashing up the sides, counter-flashing into the brick, and the cricket behind the stack are the usual suspects on a leak where the roof itself looks fine. On older chimneys the mortar joint holding the counter-flashing is often the actual failure rather than the metal.
Clermont sits in the Blue Ridge foothills, which puts it in a different roofing climate from most of Georgia. The mountains get real freeze-thaw cycling: water works into a hairline gap in flashing during the day, freezes overnight, expands, and opens the gap a little wider. Repeat that through a Hall County winter and a joint that was watertight in October is leaking by March. Ice at the eaves is the other one — meltwater running down a warm roof refreezes over the cold overhang and backs up under the shingle course, which is how water ends up inside a roof with no visible damage at all. Steep pitches shed snow well but make access harder, and older stock here runs to standing-seam and pressed metal, which fails at the fastener rather than the panel.
Clermont has a population of about 1,021, and the housing stock here sets the pattern for what fails first on a roof.
Sealant buys a season at most. It is applied over a joint that is moving, so it cracks at the first full temperature cycle. Where flashing has genuinely failed, rebuilding it is the repair; caulk is a way of paying twice.
It can. A cracked crown, a missing cap, or spalled brick lets water into the stack and it shows up inside looking exactly like a flashing leak. Worth checking both — they are different trades and different fixes.
