Southern Michigan gets the winter the rest of our territory only tastes
We work the first tier of counties across the Michigan line out of Fort Wayne, and a bit beyond it. The difference from northeast Indiana is the snow. Lake-effect off Lake Michigan is a real event in the western counties and tapers as you go east toward Hillsdale and Lenawee. It comes earlier, there is more of it, and it stays.
For a roof, the deep cold is not the problem. The freeze and thaw on either side of it is. Snow melts against a warm deck, refreezes at the cold eave, and backs water up under the roofing. Metal changes what happens when that ice forms, not whether it forms: a mechanically seamed panel gives the backed-up water no fastener head or shingle edge to work under. The attic ventilation and the membrane at the eave still do the real work, and I will say so if your attic runs warm.
Metal also sheds snow all at once. A roof plane's worth letting go over a doorway, a deck or a propane line is not a small event, and on the lake houses snow retention above anything you walk under belongs in the quote from the start.
The houses
Southern Michigan is lake country, college towns, older industrial cities and farm ground, and the roofs split accordingly. Lake cottages take wind off open water, where a concealed-clip panel with no screw head exposed earns its cost. The older city neighborhoods and the historic towns have steep, cut-up roofs where the flashing is the job and the plank decking has sometimes been wet. The farmsteads already have screw-down panel on the barn, and that is a fair trade there; on the house you plan to keep, the rubber washers under the screws wear out around year ten to twelve, and I steer people to a concealed-fastener system. We will not install exposed fastener under 4/12 anywhere.
A mechanically seamed standing seam fits the long runs and the low-slope additions. An interlocking metal shingle fits the steeper traditional roofs at 3/12 or better. Stone-coated steel I am cautious recommending for a house, because it manages water after it gets in.
When I tell Michigan homeowners not to do this
If you are selling in the next few years, good asphalt is the rational choice. If one flashing or one pipe boot is leaking on a roof with life left in it, that is a repair — we do not take repair calls. If you want shingles again, you want a different contractor. If the smallest number this year is the question, metal loses that comparison.
Being straight about distance
Michigan is not our home market — Fort Wayne is. The near towns along the line are about an hour and a quarter from the office; Kalamazoo, Battle Creek, Adrian and Jackson are closer to two, and that is the far edge of where we work. If you would rather have a contractor whose crew is ten minutes away, that is a legitimate thing to want, and there are good ones up here.
What we bring is that we install metal only, our crews are manufacturer-certified, and the warranty transfers if you sell. We are licensed and in good standing in Michigan; our business identification number is 802491909, and we carry general liability, workers' comp, auto and umbrella insurance on every project. If that is what you are shopping for, the drive does not change the roof. The communities we serve are listed below.
