Winters in Michigan are quite long and typically come with snow, freezing rain, or sleet.
Under these circumstances, in order to have the comfort you need in the living space, you have to ask yourself if your roof is sturdy enough to survive the weather in the cold season. If the roof is very old, it is good to consider renovating it prior to the beginning of winter, to avoid the specific problems of this season. Although they are more expensive, strong and durable roofing materials are preferable to the cheaper ones because they provide much better protection in extreme weather conditions and have a very long life span (some of them come with guarantees 50 years and longer).
If performing a thorough inspection of the roof is not your competence, you should call a specialist able to to provide you with the best solutions.
The condition of the roof cover and the accessories must be impeccable, otherwise repairs are in order and should be scheduled as soon as possible. Also, the perspective of the upcoming cold season should motivate you to think about adding more insulation to your roof, if you have not done it yet.
The gutters and downspouts should be cleaned of leaves, moss and twigs, to ensure proper drainage of rainwater and water resulting from snow melting. A local roofer found here https://www.roofonemichigan.com/port-huron-mi-roofing-experts.html can get your roof in tip top shape for winter.
