Emergency tarping
Buying time when the roof cannot be fixed today
Attic ventilation works as a pair: intake low at the soffits, exhaust high at the ridge. Get the balance wrong — or block the intake with insulation pushed into the eaves — and the roof space stops breathing. The result shows up as condensation on the underside of the decking, as shortened shingle life from trapped heat, and in colder parts of the state as ice damming, because a warm roof melts snow that then refreezes over the cold overhang. A lot of apparent leaks are actually ventilation problems.
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.
Routinely. Condensation forming on cold decking drips onto insulation and shows up as damp patches that behave almost exactly like ingress. The tell is that it tracks cold weather rather than rain.
No. Mixing exhaust types — ridge vents and powered fans, say — can make a fan pull air from the ridge instead of the soffits, which short-circuits the whole system. Balance between intake and exhaust matters more than total area.
