ByTed Sellers October 23, 2026October 23, 2026

Can Freeze-Thaw Cycles Loosen Standing-Seam Roof Clips in Minnesota?
ByTed Sellers October 9, 2026October 9, 2026

Freeze-thaw cycles alone aren’t a reliable explanation for loose standing seam roof clips. A leak after a Minnesota thaw can indicate a seam, flashing, drainage, or attachment problem.

Are Metal Roof Ice Dams Different From Shingle Ice Dams?
ByTed Sellers September 16, 2026September 16, 2026

Short answer: Yes. Metal roof ice dams can form when attic heat melts snow above a cold roof edge, as they can on asphalt shingles. Both systems can develop ice dams under those conditions, but water behaves differently. Backed-up water can move beneath shingle tabs, while metal roofing can carry it under panels, seams, transitions,…

Can Snow Load Damage Commercial Roof Deck Fasteners?
ByTed Sellers September 9, 2026September 11, 2026

Yes. Snow load roof damage can affect a commercial roof deck’s fasteners, but snow rarely pulls a sound fastener out by itself. Drifts and deck deflection can compress insulation, deform plates, enlarge deck holes, and open seams.

Don’t chip at ice, walk on a slick membrane, or make broad permanent repairs before the source and moisture spread are documented. A frozen roof leak can look inactive by morning…
