OVERVIEW

Roofs in the Puget Sound fight 150+ rain days a year. We use upgraded synthetic underlayments, ice-and-water shield at every penetration, and step + counter flashing details that pass inspection on the first try. The roof itself is the cheap part — flashing is what fails.

Composition shingle is still the right answer for most Seattle homes (30-year architectural, GAF Timberline or CertainTeed Landmark). Standing-seam metal is the upgrade when you want 50+ years and don't mind the upfront cost. Flat-roof assemblies use TPO or EPDM with proper drainage detailing.

What we build

SCOPE
  • 01Composition + metal roofing
  • 02TPO / EPDM flat assemblies
  • 03Synthetic underlayment
  • 04Ice-and-water shield
  • 05Step + counter flashing
  • 06Gutter + downspout integration

Phased process

PROCESS
  1. 01

    Inspection & estimate

    Walk the roof, identify flashing failures, check decking for soft spots, measure precisely for material order.

  2. 02

    Tear-off & dry-in

    Strip to deck, replace damaged sheathing, install ice-and-water at eaves and penetrations, synthetic underlayment on field.

  3. 03

    Flashing

    Step flashing at sidewalls, counter flashing at chimneys, vent boots, kick-out flashing at wall terminations.

  4. 04

    Roofing install

    Starter strip at eaves, composition shingles with 6-nail pattern, ridge vent or standing-seam panels installed to manufacturer spec.

  5. 05

    Final & cleanup

    Magnetic sweep for nails, gutter clean, final inspection, manufacturer warranty registration.

Cost drivers

COST
  • Roof complexity (gables, valleys, dormers)+15–40% labor over simple ranch roof
  • Decking replacement+$2–$4/sf for any sheathing replacement during tear-off
  • Roof pitch (steep slope >9/12)+30–60% labor for staging, safety, and slower production
  • Material upgrade (comp → metal)Comp $6–$9/sf → standing-seam $14–$22/sf installed
  • Skylights, vents, and penetrationsEach new penetration is +$400–$1,500 with proper flashing

Codes & permits

COMPLIANCE
  • IRC R905 (roofing)

    Sets underlayment, flashing, and ventilation requirements. Ice-barrier required in regions with average January temp under 25°F — Seattle is borderline; we install ice-and-water shield as best practice regardless.

  • WSEC 2021 (cool roof / radiant barrier)

    Optional in residential but reduces summer heat gain. We discuss for south-facing high-sun roofs.

  • Manufacturer warranty conditions

    30-year shingles warranty requires manufacturer-approved underlayment, ventilation, and starter strip. We document at install.

WHEN_YOU_NEED

Is roofing the right call?

  • Roof is 18–25+ years old or showing curling, granule loss, or visible patches
  • Active leaks during winter storms
  • Selling within 5 years and inspection will flag the roof
  • Combining with insulation, solar, or attic ventilation upgrade

Roofing questions

FAQ
  • Q.01

    How long does composition shingle last in Seattle?

    25–35 years for 30-year architectural shingles, properly installed with synthetic underlayment and ventilation. Premature failure (15–20 years) is almost always traceable to inadequate ventilation or shortcut underlayment.
  • Q.02

    Should I switch to a metal roof?

    Worth considering if you plan to stay 15+ years. Standing-seam metal lasts 50+ years, sheds rain and moss aggressively, and supports solar mounting without penetrating the membrane. Upfront cost is 1.6–2.5× composition.
  • Q.03

    How long does a re-roof take?

    Typical 2,000 sf single-family roof: 2–4 days. Add 1–2 days for complex roofs with valleys, dormers, or multiple penetrations. Metal roofs take longer (5–8 days) because of panel layout and seaming.
  • Q.04

    Do you handle insurance claims?

    Yes — we document damage, work with adjusters, and bid to insurer's pricing system on storm-damage and water-loss claims. Most insurance roofs in Puget Sound trace to wind or fallen-tree damage.
