Ferndale Siding Board & Batten Siding Built for a Peninsula, Not a Catalog Photo
Point Roberts sits on its own piece of geography — a five-square-mile point of land connected to the rest of Whatcom County only by water or by driving through Canada. That isolation shapes everything about how a home ages here, and it shapes what board and batten siding needs to survive on it. The vertical lines and crisp shadow lines of board and batten look great on the peninsula's mix of cottages, remodels, and newer builds, but the look only holds up if the material and the installation are matched to the site. Salt air off Boundary Bay and the Strait of Georgia, driving rain that comes in sideways off the water, and a moss season that runs longer here than almost anywhere else in the county are not backdrop details — they're the actual design brief.
This page is about that one job, on that one stretch of coastline: board and batten siding installed correctly for a Point Roberts home, using the one product we install everywhere — James Hardie fiber cement.
What Point Roberts' Climate Actually Does to Siding
Salt Air
Being surrounded by saltwater on three sides means airborne salt is a constant, low-grade exposure — not just a storm event. Salt accelerates the breakdown of fasteners, coatings, and caulk faster than it does a few miles inland. Any siding material that depends on a site-applied paint film to stay watertight will show that wear first in a place like this.
Driving Rain
Point Roberts catches wind-driven rain with almost nothing to break it up before it reaches a wall. That means water isn't just falling on the siding — it's being pushed sideways and upward into seams, laps, and butt joints. A board and batten assembly with the wrong flashing details or the wrong gap spacing will take on water in exactly those spots.
Moss Season
Shaded, north-facing walls and roof lines in this part of Whatcom County stay damp for months at a stretch. Moss and algae don't just look bad — sustained moisture against a wall is what rots wood substrate and delaminates poor-quality panel products from the inside out.
None of these three conditions is unique to Point Roberts on its own. What's unique is having all three, at this intensity, on essentially every wall of a home, year-round.
What a Correct Board & Batten Job Actually Involves
Board and batten looks simple — wide boards, thin battens over the seams — but the parts you don't see are what determine whether it lasts. On a site like this, we don't treat any of the following as optional:
- Rainscreen gap: A drainage gap behind the siding lets any water that does get past the cladding drain and dry instead of sitting against the wall sheathing.
- Weather-resistive barrier, installed and lapped correctly: Every seam and penetration gets integrated with proper shingle-lap sequencing, not just stapled and hoped for.
- Flashing at every horizontal transition: Window heads, roof-to-wall lines, and deck ledgers all need metal flashing, not caulk, doing the actual water-shedding work.
- Correct batten spacing and fastening: Battens need to land over structural framing or blocking with the fastener pattern the manufacturer specifies, not wherever looks even.
- Minimal reliance on sealant: Caulk is a backup, not the primary defense. In a driving-rain climate, a design that depends on sealant staying perfect for 20 years is a design that will fail.
This is the difference between a board and batten wall that photographs well at handoff and one that still looks and performs the same way after a decade of Whatcom County winters.
Why We Only Install James Hardie for This Application
Board and batten is one of the styles where the material choice matters the most, because the boards are large, exposed, and vertical — meaning they see more direct rain and more thermal movement than shorter horizontal lap boards. We install James Hardie fiber cement for board and batten applications specifically because:
- Non-combustible core: Fiber cement doesn't rot, and it isn't a food source for the moss, algae, and mildew that Point Roberts' damp shade produces.
- Factory-applied ColorPlus finish: The color and protective coating are baked on at the factory under controlled conditions — not applied on-site where salt air and moisture affect cure quality. That matters directly for how the finish holds up under UV and salt exposure.
- Climate-engineered HZ formulation: Hardie's HZ5 product line is engineered for the Pacific Northwest's wet, freeze-prone conditions, which is a closer match to a Point Roberts winter than a general-purpose siding formulation.
- Dimensionally stable: Fiber cement moves far less with humidity swings than wood-based or engineered-wood panel products, which keeps butt joints and batten reveals tighter over time.
- Strong transferable warranty: Backed by a manufacturer warranty that survives a change of ownership — worth noting on a peninsula where vacation and second homes change hands regularly.
We don't install vinyl, LP SmartSide, or cedar board and batten, and we won't pretend that's simply a matter of taste. Vinyl board and batten depends on trim and channel systems that trap moisture in a rain-heavy climate. Engineered wood products can perform well when detailed and maintained perfectly, but that's an on-going maintenance bet we don't think makes sense against this specific coastline. Cedar looks beautiful and ages naturally, but natural wood board and batten in a moss-prone, salt-air environment means a recurring maintenance and refinishing cycle that most homeowners don't want to sign up for indefinitely. James Hardie is the one product in this category where we can stand behind the long-term result without qualifications.
How the Job Runs, Start to Finish
1. Site & Exposure Assessment
We look at which walls take direct wind-driven rain, which stay shaded and damp longest, and where the existing siding or substrate already shows moisture damage before a single board comes off.
2. Substrate Check
Board and batten replacements often uncover sheathing or framing that's been quietly absorbing moisture behind failing siding for years. We check for this before covering anything back up — it's cheaper to fix now than to find out in five years.
3. Weather Barrier & Flashing Install
This is the step that actually determines whether the wall stays dry — done correctly, in the right sequence, before any batten goes up.
4. Board & Batten Installation
Hardie panels and battens are installed to manufacturer fastening spec, with attention to reveal consistency and correct clearances at the foundation, roofline, and trim.
5. Final Inspection
We walk the finished wall for flashing, caulking at the few joints that need it, and fastener pattern before calling the job done.
Board & Batten Material Comparison
| Material | Salt Air Resistance | Driving Rain Performance | Moss/Moisture Resistance | Long-Term Maintenance |
|---|---|---|---|---|
| James Hardie Fiber Cement | Strong — factory finish, non-porous core | Strong when detailed correctly | Doesn't feed moss or algae growth | Low — occasional wash, repaint on decades-long cycle |
| Cedar | Moderate — needs consistent sealing | Moderate — prone to cupping/checking | Susceptible without regular treatment | High — refinishing cycle required |
| Vinyl Board & Batten | Moderate — can become brittle over time | Weak at trim/channel joints | Can trap moisture behind panels | Low labor, but limited repair options |
| Engineered Wood (LP-type) | Moderate — sensitive to sustained moisture | Weak if edges/seams aren't sealed perfectly | Vulnerable if coating is compromised | Moderate to high — edge sealing is ongoing |
Cost Factors for a Point Roberts Board & Batten Project
| Factor | Why It Affects Price |
|---|---|
| Wall exposure | Walls facing direct wind-driven rain often need extra flashing detail work |
| Substrate condition | Rotted sheathing or framing found during tear-off adds repair scope |
| Board width & reveal design | Wider boards and custom reveal spacing change material takeoff and labor time |
| Trim & corner detailing | Board and batten has more visible trim than lap siding, adding material cost |
| Site logistics | Material delivery and crew scheduling to Point Roberts take extra planning versus mainland Ferndale jobs |
Maintenance Checklist for Homeowners
- Rinse siding annually to remove salt residue, especially on walls facing open water
- Check shaded, north-facing walls each fall for early moss or algae growth
- Inspect caulking at trim and penetrations yearly — replace if it's cracked or pulling away
- Keep gutters clear so overflow doesn't run down and pool behind battens
- Walk the foundation line after major storms to check for standing water against the bottom board
Why a Crew That Already Works Point Roberts Matters
Point Roberts isn't a normal service call. Crews and material deliveries either cross an international border through Canada or come in by boat — there's no quick same-day run back to a supply yard if something's short. A contractor who hasn't planned for that reality shows up unprepared, and unprepared crews cut corners to make the schedule work. We already build Point Roberts logistics into our scheduling and material staging out of Ferndale, so the border crossing and the remote location are a planning detail on our end, not a problem on the homeowner's.
Being based in Whatcom County also means we're not guessing at how this climate treats a wall — we see the same salt air, the same driving rain, and the same moss season on jobs across Ferndale and the surrounding coastline. That's the experience that shows up in flashing details other crews skip.
