Roofing, Siding, Windows

The building envelope — done watertight.

Your roof, siding, and windows are the envelope that keeps Pacific Northwest weather out of your walls. We install and replace all three as a system, so flashing details line up and water goes where it should — off the building.

Most envelope failures happen at the transitions: where the roof meets a wall, where a window meets siding. We detail those connections properly with the right underlayment, flashing, and drainage plane. Composition and metal roofing, fiber-cement and LP siding, and energy-efficient windows that cut your heating bill and pass current energy code.

What's included

  • Composition, metal, and flat roofing

    Composition shingle, standing-seam and other metal roofing, and low-slope membrane systems — installed with the underlayment, ice-and-water and ventilation details that make a roof last.

  • Fiber-cement, LP, and wood siding

    Fiber-cement (HardiePlank and similar), LP SmartSide and wood siding over a weather-resistive barrier and rain screen, so water that gets behind the siding drains out.

  • Energy-efficient window replacement

    Energy-efficient windows that pass the current Washington State Energy Code, flashed into the WRB in the right sequence so the wall stays dry.

  • Proper flashing and weather-resistive barrier

    The transitions — roof to wall, window to siding, deck ledger to house — flashed as a system, because that's where most envelope failures start.

  • Gutters and drainage

    Gutters and downspouts sized for 40 inches of rain, discharging away from the foundation.

  • Dry-rot repair at failed transitions

    When we open siding and find rot at a failed window or roof-to-wall transition, we repair the structure, document it and re-detail the envelope so it doesn't come back.

How it works

  1. 1
    Free advice visit

    We look at the roof, siding, windows and the transitions between them, and tell you what needs replacing versus repair.

  2. 2
    Scope and selections

    Materials, colors and profiles chosen; windows measured; a permit pulled where the jurisdiction requires it.

  3. 3
    Tear-off and repair

    Old roofing or siding off, sheathing and framing inspected and repaired, dry rot replaced.

  4. 4
    Install as a system

    Underlayment, WRB, flashing, roofing, siding and windows in the right sequence.

  5. 5
    Final walkthrough

    Every transition checked, the site cleaned, the final inspection passed where permitted.

The same ten-step process runs every project we build — see how we work.

What it costs

Roofing is priced by area and pitch, siding by wall area and material, and windows per opening by size and type — with tear-off, sheathing repair and the amount of dry rot found driving the difference between a clean job and an expensive one. Doing roof, siding and windows together costs less than doing them in three separate mobilizations because the flashing is detailed once.

Timeline

  1. Scope and ordering

    Measurements, selections and window lead time.

  2. Tear-off and repair

    Old materials removed and the structure inspected; rot repair happens here.

  3. Install

    Roofing first on a combined project, then windows and siding, each flashed into the next.

  4. Gutters and cleanup

    Gutters, downspouts, final details and a site clean.

Permits and codes

Re-roofing and window replacement need a permit in many Washington jurisdictions, and siding replacement does when sheathing or structure is repaired; windows must meet the current energy code's U-factor requirements. Rules vary by city.

We pull the permits, document rot repair for the inspector and schedule the inspections around the tear-off so the house isn't open longer than it has to be.

Questions, answered

Repair when the failure is local — a flashing, a few shingles, a roof-to-wall transition — and the rest of the roof has life left. Replace when the shingles are at the end of their life across the roof, when there's more than one layer, or when repairs keep coming back. We tell you which after we're on the roof.

Fiber-cement is non-combustible, holds paint well and resists rot and insects; LP SmartSide is an engineered wood that's lighter, easier to work and takes impact well. Both perform in Northwest weather when installed over a proper weather-resistive barrier and rain screen, which matters more than the brand.

Windows are flashed into the weather-resistive barrier in sequence — sill pan first, then jambs, then head — so any water that gets past the siding drains out, not in. A rain screen is the small gap behind the siding that lets that water drain and the wall dry; together they're why a wall stays dry for decades.

In many Washington jurisdictions, yes — re-roofing and window replacement are permitted work, and siding is when structure is repaired. We confirm your city's rules and pull what's required.

Replacement windows must meet the Washington State Energy Code's maximum U-factor for fenestration, which in practice means modern double- or triple-pane units with low-e coatings. The permit documents it, and the savings show up on the heating bill.
