Blaine Roofing Board & Batten Siding Built for Lynden's Weather
Lynden sits inland from the coast, but that doesn't mean it's spared from the weather that defines this corner of Whatcom County. Homes here still deal with salt-laden air pushing in off the Strait of Georgia, long stretches of driving rain through the fall and winter, and a moss season that can run for months on any siding that holds moisture. Board and batten siding, done right, is one of the better-looking and more durable ways to handle all three — but "done right" is doing a lot of work in that sentence, and it's where most board and batten jobs go wrong.
This page covers what board and batten siding actually is, what a correct installation requires in this climate, and why we install it exclusively in James Hardie fiber cement rather than the vinyl, LP SmartSide, or cedar versions you'll also see offered around the county.
What Board & Batten Siding Is
Board and batten is a vertical siding style — wide flat panels installed vertically, with narrow strips (battens) covering the seams between them. It's a classic Pacific Northwest farmhouse look, and it's especially popular on Lynden homes with barn-style, craftsman, or modern-farmhouse exteriors. The style also works well as an accent on gable ends, entry features, or a mix with horizontal lap siding elsewhere on the same home.
What most homeowners don't realize is that "board and batten" describes an appearance, not a material. You can build that look out of vinyl panels, engineered wood, cedar boards, or fiber cement. The material underneath the battens is what determines whether the siding actually holds up to a Whatcom County winter or starts showing problems in five to eight years.
Why the Vertical Style Matters Here
Vertical siding sheds water differently than horizontal lap siding. Done correctly, board and batten gives rain fewer horizontal ledges to sit on and more of a straight path down and off the wall — which matters when your siding is dealing with driving rain for months at a stretch. Done incorrectly, the battens and seams become exactly the kind of trap where moisture sits, wood swells, and moss gets a foothold.
Why We Only Install This in James Hardie
We install board and batten siding using James Hardie's fiber cement panel systems — never vinyl board and batten panels, LP SmartSide, or raw cedar boards. That's a deliberate standard, not a sales preference, and it comes down to how each material behaves once it's actually up on a wall in this climate.
| Material | How It Handles Salt Air & Rain | Where It Struggles Long-Term |
|---|---|---|
| James Hardie fiber cement | Non-combustible, dimensionally stable, factory-cured ColorPlus finish resists fading and doesn't rely on paint film to stay sealed | Requires correct install detailing (it's not forgiving of shortcuts) and costs more upfront |
| Vinyl board and batten | Won't rot, but expands and contracts more with temperature swings, which can open gaps at battens over time | Can crack in cold snaps, fades with UV exposure, seams are a weak point in wind-driven rain |
| LP SmartSide (engineered wood) | Reasonable moisture resistance when the factory coating is intact | Wood-based core is vulnerable if edges, cuts, or seams aren't sealed exactly to spec — a common failure point in wet climates |
| Cedar boards | Natural, breathable, ages well when maintained | Needs ongoing refinishing, is a food source for moss and mildew in constant damp conditions, and is combustible |
We're not telling homeowners these other products don't have a place — LP SmartSide and cedar both have real fans, and vinyl board and batten is a legitimate budget option. We're telling you why we, specifically, stopped installing them: we were seeing the same climate-driven problems repeat themselves on callbacks and inspections, and we'd rather stand behind one system we trust completely than offer several we have reservations about.
What Correct Board & Batten Installation Involves
The board and batten look is unforgiving of bad water management, because every batten seam is a potential entry point if it's not built correctly. A proper installation isn't just nailing boards to the wall — it's a system.
Weather-Resistive Barrier and Drainage Plane
Every wall gets a continuous weather-resistive barrier behind the siding, with a drainage gap so any moisture that does get past the cladding has somewhere to go besides your sheathing. This matters more on vertical siding than horizontal, because water traveling down a wall in a driving rain has more distance to cover before it hits a flashing detail.
Batten Spacing and Fastening
Battens need consistent spacing, correct fastener placement into framing (not just sheathing), and the right nail pattern for the panel width — James Hardie publishes specific fastening schedules for its board and batten systems, and skipping them is one of the most common corner-cutting moves we see on other crews' work.
Clearances That Keep Moisture Out
Siding that runs too close to grade, a deck surface, or a roofline gives moss and standing water a place to work on the bottom edge of the panel. We hold the manufacturer's minimum clearances at grade, roof lines, and decks — non-negotiable, even when it means an extra step during install.
Caulking and Sealant Details
Butt joints, trim intersections, and penetrations (hose bibs, vents, light fixtures) all get sealed with a product rated for the movement and exposure involved — not just whatever caulk happens to be in the truck.
Our Process for a Lynden Board & Batten Project
- On-site assessment of your current siding, sheathing condition, and any moisture or moss damage already present
- Written estimate covering material, tear-off, and installation — no vague allowances
- Removal of old siding and inspection of the sheathing underneath before anything new goes up
- Installation of weather-resistive barrier and drainage plane per manufacturer spec
- James Hardie panel and batten installation with correct fastening schedule and clearances
- Sealing, trim work, and paint touch-up per the ColorPlus or field-paint system you've chosen
- Final walkthrough so you know exactly what was done and what maintenance, if any, it needs going forward
Why a Crew That Already Works Lynden Matters
Board and batten siding isn't exotic, but it does reward experience with local conditions. A crew that's worked across Whatcom County knows which walls on a given lot orientation take the worst of the driving rain, how much moss buildup is normal versus a sign of a bad water management setup, and how salt-laden air moving in off the water affects fastener choice and finish longevity even well inland. That's not something you get from a general contractor doing their first board and batten job — it's something you get from having done this specific work, on this specific type of home, in this specific climate, more than a few times.
It also matters for the boring-but-critical stuff: knowing what building permits or inspections apply in your area, sequencing a tear-off around Whatcom County's wet season instead of leaving sheathing exposed during a storm cycle, and having a crew size that can actually finish a wall section before the weather turns.
Maintenance and What to Expect Over Time
One reason we like fiber cement for board and batten specifically is the low ongoing maintenance. James Hardie's ColorPlus finish is factory-baked and warranted against fading and cracking, so you're not on a recurring repaint schedule the way you are with cedar. That said, no siding is maintenance-free in this climate:
- Rinse pollen, dust, and mildew film off the siding once or twice a year — a garden hose is usually enough
- Keep gutters and downspouts clear so water isn't sheeting down the wall in places it shouldn't be
- Trim back vegetation and keep mulch beds from piling up against the bottom edge of the siding, which traps moisture and encourages moss
- Have caulking and trim seals checked every few years, especially around penetrations
What Affects the Cost of a Board & Batten Project
| Factor | Why It Matters |
|---|---|
| Home size and wall complexity | More corners, gables, and trim details mean more cutting, fitting, and batten work |
| Tear-off vs. new construction | Removing old siding and repairing any sheathing damage found underneath adds labor |
| Finish choice | Factory-applied ColorPlus finish costs more upfront than field paint but needs far less maintenance over the siding's life |
| Accent vs. full board and batten | Many Lynden homeowners use board and batten on gables or entry features only, paired with lap siding elsewhere — which changes total material cost |
| Site access and lot conditions | Setback, landscaping, and how the home sits on the lot affect staging and labor time |
We give a written, itemized estimate before any work starts — no broad allowances that turn into surprises later.
