Gutter materials

Best gutter materials for Seattle rain

Choosing the right gutter material and guard system prevents overflow, protects siding, and keeps Rainwise projects compliant.

Seattle’s heavy rainfall demands seamless gutter systems that resist corrosion and manage pine needles, moss, and fir cones. Osprey Exterior installs aluminum and steel gutters with custom mesh guards that outperform national franchises while keeping Rainwise rebate eligibility intact.

Seamless aluminum vs. steel

Seamless aluminum remains the most popular option for Pacific Northwest homes thanks to its lightweight construction and wide color range. For waterfront or exposed sites, we recommend galvalume steel with baked-on coatings. Both pair well with cistern downspout diverters when you plan to capture Rainwise rebates.

Guard systems that actually work

Big-box filter brands often clog at the first sign of cedar needles. Our in-house mesh guard features a marine-grade stainless screen that keeps debris out while allowing high-volume flow. The micro-mesh design also meets Seattle’s stormwater code when combined with inspection-ready documentation.

Installation and maintenance

  • Precision fabrication: Every gutter run is extruded onsite for perfect lengths and minimal seams.
  • Hidden hangers: Premium hangers spaced every 18 inches withstand snow loads on the Eastside.
  • Maintenance plan: Enroll in our quarterly or annual cleaning to keep warranties valid.

Integrating gutters with our service comparison table helps homeowners understand timelines and maintenance requirements relative to Rainwise or drainage projects.

Signs it’s time to upgrade

Look for peeling paint, fascia rot, siding streaks, or basements with damp corners after storms. These are early indicators that gutters are undersized or clogged. We can bundle replacements with Seattle or Bellevue service area packages for rapid scheduling.
