Any reno where the roof is removed is a risk for rain damage so long as there's no roof. When we added the 2nd story to our house in Calgary in 2005, we were roofless for about 3 weeks. Not long after they took it off, it rained (on a Sunday morning at 8 AM) and started leaking into my house. I immediately called my contractor, who showed up within 20 minutes and re-tarped me. That one wrecked a bit of ceiling drywall that we should have replaced, for you could still see it years later. Such are the perils of removing roofs.
