Sure, you can replace a roof in winter, but it's trickier than doing it in milder weather. The cold can make shingles brittle and harder to work with, plus snow or ice on the roof creates a safety hazard. You also need to deal with shorter daylight hours. But if there's an emergency leak, or you're set on doing it now, a good roofer will use special techniques like heating the shingles or working in sections. Just expect the job to take a bit longer and cost more because of the conditions.
