Anacortes Roofing Board & Batten in a Waterfront Skagit County Climate
Board and batten is one of the most requested siding styles we see in La Conner, and it's easy to understand why. The vertical lines suit the town's mix of historic waterfront homes and newer builds along the Swinomish Channel, and it reads as clean, tall, and a little more custom than standard lap siding. But board and batten is also one of the least forgiving siding styles to get wrong. Every vertical seam, every batten, every horizontal joint is a place water can find its way in if the assembly behind the boards isn't built correctly — and La Conner's climate does not give a mediocre installation much room for error.
We install board and batten exclusively in James Hardie fiber cement. This page walks through what La Conner's weather actually does to a vertical siding system, what a correct installation involves underneath the boards you see, and why hiring a crew that already works this stretch of Skagit County matters more here than in a lot of other places.
What Salt Air, Driving Rain, and Moss Season Do to Vertical Siding
Salt Air and Fastener Corrosion
Homes near the Swinomish Channel and the broader Salish Sea shoreline sit in a mild but persistent salt-air environment. Salt doesn't rot fiber cement, but it does accelerate corrosion in anything metal — nail heads, batten fasteners, flashing, and trim hardware. A board and batten wall has more exposed fastener points than a standard lap wall, since battens are face-nailed or blind-nailed along their full length. If those fasteners are the wrong grade of corrosion-resistant material, you get rust streaking down the boards within a few years and eventually fastener failure, which is a maintenance headache long before the siding itself would ever need replacing.
Wind-Driven Rain at Vertical Seams
Skagit County gets a long, wet fall-through-spring stretch, and storms coming off the water bring rain sideways, not straight down. On a lap-sided wall, gravity and shingle-style overlap do a lot of the work keeping water out. On a vertical board and batten wall, there's no natural overlap doing that job — the water resistance has to come from the drainage plane and flashing details behind the boards, not the boards themselves. This is the single biggest difference between board and batten and horizontal siding, and it's the reason a rushed or corner-cutting install shows problems faster in a place like La Conner than it would somewhere drier and calmer.
A Long Moss and Algae Season
Shaded walls, north-facing elevations, and anything close to overhanging trees stay damp for extended stretches through the region's moss season. Moss and algae growth is mostly cosmetic on a properly finished fiber cement wall, but it's a real maintenance issue on wood, and it can mask early water intrusion signs on any siding if it's allowed to build up unchecked around battens and trim.
What a Correctly Built Board & Batten Wall Actually Looks Like
The boards and battens you see are the last thing installed, not the first. What's underneath determines whether the wall performs in La Conner's climate for decades or becomes a callback within a few wet seasons. A correct assembly, working from the studs outward, includes:
- A continuous weather-resistant barrier (WRB) installed shingle-style, lapped correctly at every seam
- A drainage gap (rainscreen furring) behind the siding so any water that does get past the surface has somewhere to go and dry out
- Flashing at every horizontal transition — window heads, door heads, trim boards, and any place the wall plane changes
- Kickout flashing wherever a roofline meets a sidewall, directing water away from the wall instead of behind it
- Correct fastener type, length, and spacing per the James Hardie installation manual for the specific product and exposure
- Sealed and primed cut edges — factory-primed ColorPlus panels lose their protection wherever they're cut on site unless that edge is properly sealed
- Proper clearance between the bottom of the siding and grade, decks, or roof surfaces so splashback and standing water aren't sitting against the boards
Skip the rainscreen gap or shortcut the flashing, and the wall can look identical to a correct install for the first year or two — the difference only shows up later, in the sheathing behind it, which is the expensive kind of mistake to find out about.
The James Hardie Products We Use for This Look
Board and batten in fiber cement is typically built one of two ways, and we choose based on the home and the look the owner wants:
Panel-and-batten: Large HardiePanel vertical siding sheets (smooth or lightly textured) are installed over the rainscreen and WRB, with Hardie trim battens fastened over the panel seams at regular intervals. This is the more common, more cost-effective approach and gives a clean, tailored look.
Board-on-board: Individual vertical boards are installed with a gap between them, then a narrower batten is fastened over each gap. This gives a deeper, more dimensional shadow line and is closer to the traditional farmhouse look, at a higher material and labor cost.
All of it comes finished in James Hardie's ColorPlus factory finish — baked-on color that isn't dependent on a field-applied paint job holding up against salt air and driving rain. In a climate that's hard on painted wood trim, not needing a repaint cycle every several years is one of the more practical advantages of going this route over a wood or engineered-wood batten system.
Board & Batten vs. Lap Siding for This Kind of Exposure
Owners considering board and batten for a La Conner property often ask how it actually compares to standard horizontal lap siding once you factor in the local weather. There's no universally "better" answer — it depends on wall exposure and what the home needs — but the trade-offs are worth knowing before you commit to a style.
| Factor | Board & Batten (Vertical) | Lap Siding (Horizontal) |
|---|---|---|
| Water shedding on its own | Relies on the drainage plane behind it; no natural shingle overlap | Natural gravity overlap sheds most surface water before it reaches the wall |
| Best exposure | Works well anywhere when built with a rainscreen; especially suited to gable ends and accent walls | Traditional choice for full wind- and rain-exposed elevations |
| Visual style | Farmhouse, craftsman, modern-coastal; strong vertical lines | Traditional, most common in the region; wide color and reveal options |
| Fastener exposure | More face fasteners (battens), so fastener grade matters more | Fewer visible fasteners with concealed-nail installation |
| Typical use | Full home, or as an accent mixed with lap siding | Full home, most common as the primary field material |
A lot of the board and batten homes we work on in this area actually mix the two — vertical siding on gables, dormers, or an entry feature, with lap siding across the main wall planes. It's a good way to get the look without putting every square foot of the exterior on a system that depends entirely on flawless flashing.
Our Process, Start to Finish
- On-site assessment: We look at existing siding condition, sheathing, wall orientation relative to prevailing weather, and any existing moisture or moss issues before quoting anything.
- Tear-off and sheathing check: Old siding comes off and we inspect the sheathing underneath for rot or water damage — common in this climate wherever a previous installation lacked proper flashing.
- WRB and rainscreen installation: A new weather-resistant barrier goes on correctly lapped, with furring strips creating the drainage gap behind the siding.
- Flashing: Window and door heads, trim transitions, and roof-to-wall intersections get flashed before any siding goes up over them.
- Panel or board installation: HardiePanel or individual boards are installed per Hardie's manual specifications for fastener type, spacing, and gapping.
- Battens and trim: Battens are set to the layout line, fastened per spec, and all trim and corners are finished.
- Sealing and touch-up: Cut edges are primed and sealed, seams are caulked where specified, and touch-up paint is applied to match the ColorPlus finish.
- Final walkthrough: We review the finished wall with the homeowner before calling the job complete.
What Correct Installation Costs, and Why
Board and batten pricing varies more than lap siding pricing because the two construction methods (panel-and-batten versus board-on-board) carry different material and labor costs, and because the amount of trim, corner, and flashing work scales with the home's design.
| Cost Factor | Why It Matters |
|---|---|
| Panel-and-batten vs. board-on-board | Board-on-board uses more linear material and more fastening labor per square foot |
| Rainscreen furring | Adds material and labor but is not optional in a climate this wet — skipping it isn't a real savings |
| Number of gables, dormers, or accent walls | More wall breaks mean more flashing detail and cutting |
| Existing sheathing condition | Rot repair discovered during tear-off adds cost but has to be addressed before new siding goes on |
| Trim complexity | Corner boards, window casings, and batten spacing decisions all affect labor time |
We'd rather walk a homeowner through these factors up front than quote a number that doesn't reflect what the wall actually needs. A rainscreen gap, correct flashing, and proper fastener grade aren't upgrades in this climate — they're the baseline for a board and batten wall that's supposed to last.
Checklist: What to Confirm Before You Sign a Contract
- Is a rainscreen/drainage gap included, or is siding going direct-to-sheathing?
- Does the quote specify James Hardie products by name, product line, and finish?
- Are fastener type and grade specified, not just "corrosion-resistant nails"?
- Is flashing detail (window heads, kickouts, trim transitions) called out in writing?
- Will cut edges be primed and sealed on site, and is touch-up paint included?
- Does the contractor carry manufacturer certification for James Hardie installation?
- Is there a clear plan for sheathing repair if rot is found during tear-off?
Why a Crew That Already Works in La Conner Matters
La Conner sits close enough to open water that wall exposure can vary a lot from one side of a lot to the other — a gable facing the channel takes a very different beating than a wall tucked behind a garage or a stand of trees. A crew that's worked this specific stretch of Skagit County knows which elevations need extra attention on flashing and fastener grade before they even walk the site, instead of learning that lesson on the homeowner's dime. Local experience also means knowing how the area's older homes were typically built, so tear-off doesn't turn into guesswork about what's hiding behind the existing siding.
