Flashing Installation

What This Service Involves

New flashing is essential wherever a roof plane changes direction or meets a vertical surface, and getting it right the first time is what keeps a Northwest home dry for decades. On new additions, dormers, skylights, and chimneys, we integrate step, counter, and base flashing into the underlayment so water is directed out and over the roofing rather than behind it. We favor heavier-gauge, corrosion-resistant metals here because our salt-influenced marine air and near-constant damp are hard on thin, builder-grade material. Every run is lapped in the direction of flow and tied into the drainage plane, which matters enormously on the low-slope roofs common around Seattle and Tacoma.

Benefits

Seals vulnerable joints correctly from the start rather than relying on caulk alone; Uses corrosion-resistant metal suited to marine and high-moisture air; Integrates flashing into the drainage plane so water sheds outward; Protects new additions, skylights, and chimneys against wind-driven rain; Provides a clean, finished appearance that complements the roofline

Our Process

1) Review the roof geometry and identify every joint and penetration needing flashing; 2) Select the appropriate metal, profile, and gauge for the exposure; 3) Integrate base, step, and counter flashing into the underlayment and roofing layers; 4) Fasten, lap, and seal each run and verify positive drainage

What Affects the Cost

Number and complexity of penetrations and roof transitions; Choice of flashing metal, from galvanized steel to copper; Roof pitch and height affecting access and labor; Coordination with skylights, chimneys, or new framing; Integration required with existing underlayment and roofing

Best Time of Year

Installation pairs best with the drier summer months, though we can flash new penetrations year-round when a project cannot wait.
