An ice dam at the intersection of a sloped roof and wall caused damage to the interior ceiling and wall. I cut through the surface of the ceiling and wall when it happened, to allow the collected water to drain, which took a couple days. At first a bunch rushed out, then it trickled out until a day or two after we had the dam fixed. When it was dry to the touch, I scraped/cut away all the damaged areas and applied joint compound with new tape, then used oil-based primer and painted.
Everything looks fine, but I'm worried about whether mold or some other bad stuff) could (or did) form behind the wall, either in the back of the drywall below where I repaired, or on the framing or insulation (probably R13 faced sheets).
Should I leave things as-is, or cut out a big section of drywall on the wall and ceiling and re-do it, or something else? Thanks!
