Yes, in many cases it can. Winter leaks should not be ignored because repeated freezing and thawing can make the damage worse and allow more moisture into the roof system. Some materials have limitations in colder weather, but targeted repairs can often still be completed when conditions are safe and the repair method is appropriate. At Aucoin Roofing, we assess the roof carefully and recommend the best solution based on the season, the urgency of the issue, and the condition of the affected area.
