Installing a shingle roof in the winter can raise many questions.
“Is it okay to install shingles in the winter?” Homeowners often wonder if proper seal down will occur. As a professional roofing company, we have personal guidelines that we adhere to when cold weather installation is necessary.
While immediate seal down is most likely not going to occur in colder temperatures, shingles will eventually seal down completely. Direct sunlight on newly shingled roofing ensures proper adhesion. Most asphalt shingles come manufactured with thermally activated asphaltic sealants. This sealant bonds the shingles together once applied to the roof and exposed to sufficient heat from sunlight. North slopes may require summer heat to seal down since sunlight will not directly reach the roof surface.
