Standing Seam Metal Roofing in the Puget Sound
What Is Standing Seam Metal Roofing?
Standing seam is a premium metal roof system built from long vertical panels, raised seams, and concealed fasteners.
Instead of exposed screws across the roof surface, the fasteners are hidden beneath the seams. That means fewer obvious leak points, cleaner lines, and a sharper architectural finish.
Cascade Standing Seam installs standing seam systems for ADUs, garages, additions, porches, backyard offices, and straightforward residential roofs across the Puget Sound.
Why Homeowners Choose Standing Seam
• Clean vertical panels running from ridge to eave
• Strong compatibility with future solar installations
• Concealed fasteners instead of exposed screws
• Valuable curb appeal
• Resistant to moss, mildew, pests, and rot and easier to clean
• 50+ year performance
• Substantially longer-lasting than standard asphalt roofing
• Can reduce summer cooling costs by up to 40%
• Usually weighs 50% to 75% less than asphalt shingles, reducing dead load on the structure
• Paintable later if you want a different aesthetic or want to extend coating life
Good Fit
Standing seam works best on simple residential roofs, ADUs, garages, additions, porches and backyard offices with clean roof planes and limited penetrations. It is especially strong for homeowners who care about long-term value, clean lines, and fewer replacement cycles more than installation speed.
Riskier Fit
We usually bow out early on projects with multiple valleys, several dormers, low-slope sections, complex skylight or chimney details, or hidden decking and fascia damage that changes the scope. If another roofing system or an installer with more appetite for variables makes more sense, we’ll say so.
