As a seasoned roofer, we would be willing to bet that at some point in your career, you have strongly encouraged a homeowner to replace or repair a residential roof prior to the winter season. We would also be willing to bet that said homeowners did not always take heed of your advice and expertise. Although it is best to complete roofing projects before winter, all roofing materials can be installed successfully in cold weather, given adequate precautions are taken.
