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
- 1Free advice visit
We look at the roof, siding, windows and the transitions between them, and tell you what needs replacing versus repair.
- 2Scope and selections
Materials, colors and profiles chosen; windows measured; a permit pulled where the jurisdiction requires it.
- 3Tear-off and repair
Old roofing or siding off, sheathing and framing inspected and repaired, dry rot replaced.
- 4Install as a system
Underlayment, WRB, flashing, roofing, siding and windows in the right sequence.
- 5Final 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.

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