Inventory upstream materials.
Show retained roof, gutter and wall components that could contribute runoff.

Siding in Keyport, WA.
Siding in Keyport using metallic-coated steel needs an assessment of upstream materials as well as direct contact.
Show the provider any retained copper roofing, guttering or other component whose runoff could reach the new wall. Physical separation alone may leave a wetting path unresolved.
Siding replacement
Trace copper-bearing runoff before selecting steel cladding.
Ask the provider to identify the actual wall metal and materials above it, then assess where rain or condensation travels. Keep an upstream copper source in the compatibility review even if it does not touch the siding. Agree any change to the source, drainage or cladding with the responsible providers before the finish is ordered.
Describe the wetting path.
Share safe photographs and observations without assuming a stain establishes its cause.
Coordinate the remedy.
Ask the cladding and drainage providers to resolve material compatibility and define the included work together.
Before work begins
Confirm the parcel’s actual village review.
Ask DCD to identify the property’s zone and applicable exterior-review requirements. The County quick reference’s commercial design-review triggers should not be treated as universal residential thresholds.
Keep removal, repair and any changed drainage work recognizable in the proposal and application. A compatible color sample does not settle the construction scope.
Siding questions for Keyport homeowners.
Does a gap between the metals settle compatibility?
Ask whether runoff still carries exposure to the proposed cladding.
Does matching the color identify compatible materials?
Request the actual substrates and product-specific compatibility assessment.
Can a visible corrosion mark simply be painted over?
Have the cause and affected material assessed before selecting a remedy.
Show what drains toward the proposed wall.
Share the intended cladding and any retained upstream copper or unexplained wetting pattern.
