There is no synthetic material that fully replicates the character of natural wood siding. The grain variation, the warmth, the way it holds and reflects light — these qualities are inherent to the material and are why wood siding has remained a choice for Greater Seattle homes for as long as people have been building here. The classic craftsman bungalow, the Pacific Northwest farmhouse, the midcentury modern with clear cedar cladding — wood siding is woven into the architectural identity of the region.
Integrity Roofing & Construction installs natural wood siding throughout Greater Seattle. Wood siding in the Pacific Northwest requires a level of installation expertise and moisture management detail that is higher than in drier climates. When it’s installed correctly and maintained, wood siding delivers decades of beauty and performance. When it’s not, it becomes a recurring maintenance problem. We build wood siding systems that are designed to last — backed by our 20-year workmanship warranty.

Wood Siding Profiles We Install
Cedar Lap Siding (Bevel Siding)
The most common wood siding profile in Greater Seattle — a tapered board installed horizontally with the thick edge at the bottom, overlapping the board below. Cedar lap siding is available in clear (knot-free) and knotty grades and in a range of widths. It’s the defining material of the craftsman bungalow style and suits a wide range of Pacific Northwest residential architecture.
Cedar Shiplap and Channel Rustic
Shiplap and channel rustic profiles interlock at the edges rather than lapping — creating a flatter wall plane with shadow lines at each board joint. These profiles are popular in contemporary and farmhouse-influenced designs and provide a clean, modern appearance compared to the dimensional shadow lines of traditional lap siding.
Board and Batten
Board and batten siding uses wide vertical boards with narrow battens covering the joints between them. It’s historically associated with agricultural and rural architecture but has become popular in contemporary Pacific Northwest residential design. Board and batten can be installed vertically or horizontally; vertical installation requires specific flashing and drainage details at horizontal surfaces.
Cedar Shingles (Sidewall Shingles)
Cedar shingles installed as siding — rather than as roofing — create a textured, dimensional wall surface that’s closely associated with Pacific Northwest cottage and craftsman architectural styles. Sidewall cedar shingle installation has specific installation details that differ from roofing application, including exposure, fastening, and corner and trim treatment.
Wood Siding Installation Details That Matter in Greater Seattle
Weather-Resistive Barrier
The WRB behind wood siding is the building envelope’s primary water defense. In Greater Seattle’s climate, this layer must be installed with meticulous attention to lapping, sealing at all penetrations, and integration with window and door flashings. We install WRBs to the detail level that Greater Seattle’s weather demands — not the minimum required by code.
Proper Back-Priming
All six sides of every piece of wood siding should be primed before installation — including the back face and ends that will face the WRB and trim joints. Back-priming seals the wood against moisture absorption from behind and at the most vulnerable points — end grain. Skipping back-priming on wood siding in Greater Seattle’s climate is one of the most common sources of premature paint failure and end-grain decay.
Clearances from Horizontal Surfaces
Wood siding must maintain specified clearances from rooflines, decks, and grade — typically 2 inches from horizontal surfaces and 6 inches from grade. Inadequate clearances allow water to wick from horizontal surfaces into the butt ends of siding boards, causing end-grain decay that begins before the siding is even visible from the street.
Corrosion-Resistant Fasteners
Cedar contains tannins that react with standard steel fasteners, causing corrosion and staining that bleeds through the paint surface. We use stainless steel or hot-dipped galvanized fasteners rated for cedar and other tannic wood species on every wood siding installation.
Common Wood Siding Problems in Greater Seattle — and How We Address Them
Paint Failure and Peeling
Paint peeling on wood siding in Greater Seattle is almost always related to moisture. Common sources include: inadequate back-priming at installation; moisture infiltrating from the wall cavity behind due to a failed WRB; condensation from inside the home pushing through the wall in winter; and caulk failure at joints allowing water infiltration. We investigate the source of moisture before repainting — surface preparation without addressing the underlying cause produces paint that fails again in the same cycle.
End-Grain Decay
The butt ends of wood siding boards — particularly at trim joints, corners, and window and door trim interfaces — are the most vulnerable to moisture absorption and decay. End grain absorbs water at a rate many times faster than face grain, and once decay begins at a butt end, it spreads into the board length. Regular caulk inspection and maintenance at all end-grain exposures is the most important preventive maintenance task for wood siding in Greater Seattle.
Nail Pops and Fastener Failure
Wood siding that expands and contracts significantly through seasonal moisture cycling can cause nails to work loose over time — particularly if the original fasteners were too small, too few, or driven into the wrong location. Nail pops create openings for water infiltration and are a precursor to more serious paint and substrate damage. We reset or replace popped fasteners and assess whether the original fastening pattern was adequate.
Rot at Bottom Edges and Corners
The bottom edges of siding boards and the inside corners of trim details are chronic moisture collection points on wood-sided homes in Greater Seattle. Water draining down the wall surface pools at these locations, wicking into the wood over time. We address rot by removing decayed material, treating adjacent wood, and rebuilding the affected section with proper back-priming, flashing, and clearance to prevent recurrence.
Frequently Asked Questions About Wood Siding in Greater Seattle
How long does wood siding last in the Pacific Northwest?
Properly installed, back-primed, and maintained wood siding typically lasts 25 to 40 years in Greater Seattle’s climate. Maintenance is the key variable — wood siding that is inspected and re-caulked annually and repainted on a 5 to 8-year cycle approaches its full potential lifespan. Neglected wood siding can show significant failure within 10 to 15 years.
How often does wood siding need to be painted in Greater Seattle?
In Greater Seattle’s wet climate, most wood siding benefits from repainting every 5 to 8 years — and annual inspection and spot caulking in between. North-facing and heavily shaded surfaces may need attention more frequently. Quality paint products rated for Pacific Northwest conditions extend the repainting interval.
Is wood siding harder to maintain than composite alternatives?
Yes. Wood siding requires more consistent maintenance than fiber cement, engineered wood, or vinyl alternatives in Greater Seattle’s climate. For homeowners who value the authentic character of natural wood and are willing to commit to the maintenance schedule, wood remains a rewarding choice. For those who prioritize low maintenance, a composite alternative may be more practical.
Can individual boards of wood siding be replaced without replacing the whole wall?
Yes. Selective board replacement is one of wood siding’s practical advantages. When decay or damage is localized to specific boards, we remove and replace the affected sections, matching the profile and grade as closely as available, and finish to blend with the surrounding siding.
What warranty does Integrity Roofing provide on wood siding installations?
All wood siding installations are covered by our 20-year workmanship warranty. The longevity of the installation beyond that period depends significantly on maintenance adherence; we’ll provide a realistic maintenance schedule and plan during your consultation.
