Whitefish Chain Contemporary — Standing Seam Metal

This home sits on Cross Lake near the dam, one of the 14 connected lakes that make up the Whitefish Chain — the kind of shoreline where you can run a boat from Big Trout down to the dam without ever trailering. The 2008 build has a clean, low-slope roof plane by design: large fixed-glass walls facing the water, a narrow 8/12 shed section over the lakeside porch, and a 4/12 main field the original builder covered in TPO membrane instead of a traditional profile.

The membrane did its job for about 15 years, but seam integrity was failing and the owners had dealt with two slow leaks over the past few winters — the kind of thing that's easy to miss when you're not at the cabin every week. They wanted something they wouldn't have to think about again. Standing seam metal was the answer: the 4/12 slope sits comfortably within the range for mechanically seamed panels, and a home facing open water on Cross Lake needs a roof that sheds wind-driven snow instead of holding it.

We used 24-gauge Galvalume steel with a matte charcoal PVDF finish, 18-inch panel width. On a low-slope system, the panels move more with heat and cold than they do on a steep roof, so we specified floating clips throughout the 4/12 field and fixed clips on the 8/12 shed section, which is standard at that pitch. Every panel lap was mechanically seamed, and we soldered the valley seams and sealed every penetration with a butyl tape backup.

The job ran five days, with an extra day for custom sheet-metal work around a skylight curb that needed a new aluminum adapter to marry with the panel system. The finished roof is flat-seam clean — no exposed fasteners, no penetrations in the field. Clamp-on snow guards went in above the lakeside porch, since a slab of snow sliding off a metal roof onto a walkway is a real hazard on a lake home. First winter under the new system came and went without a call.
