Valley leaks
Where two roof slopes meet
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.
Dodge County sits in Georgia's hail belt, where the spring storm line coming across the state tends to organise. Hail is the dominant roof killer here and it works slowly: the stone bruises the asphalt mat under the granule surface without breaking through, so the roof keeps water out for another season or two and then starts leaking from spots that were damaged years earlier. Add the summer heat load — Dodge County roofs run extremely hot, which ages the shingle and dries out the sealant around every penetration — and the failures cluster around pipe boots, flashing and anything with a rubber component.
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.
