Ceiling leak and water stain
Stains, bulges and damp patches inside
Slate lasts a century or more, and what fails first is almost always the fixings rather than the slate itself — nail sickness, where the fixings corrode and slates begin to slip, is the classic failure. Repair is specialised work: slates are refixed with hooks or tingles rather than simply nailed back, and walking the roof incorrectly breaks more than the original fault. Replacement is enormously expensive, so repair is nearly always the right call on a sound slate roof.
Canon 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 Franklin 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.
Canon has a population of about 643, and the housing stock here sets the pattern for what fails first on a roof.
Corrosion of the original fixings, so slates lose their hold and begin slipping one after another even though the slate itself is sound. A few slips in quick succession is the sign, and it means the roof needs assessing as a whole rather than slate by slate.
Almost always. The material has decades of life left and replacement is extremely expensive. The constraint is finding someone who works on slate properly — bad access does more damage than the original fault.
