Anacortes Siding Why Board & Batten Is Having a Moment in Skagit County
Board and batten has been around for over a century, originally as a practical way to cover gaps between wide barn boards. Today it's back on Anacortes homes for a different reason: it gives a house strong vertical lines, deep shadow lines, and a clean, modern-farmhouse look that stands out from the flat lap siding on most of the block. It works on a full exterior, as an accent over a garage or entry, or mixed with horizontal lap siding to break up a large wall plane.
The look is simple. Getting it to perform for thirty years on a house that sits a few miles from saltwater, gets pounded by driving rain off Rosario Strait, and grows moss on anything that stays damp too long is the hard part. Board and batten has more vertical seams and more battens fastened through the field than lap siding, which means more places for water to find a way in in if the wrong material or the wrong crew is behind it. That's the whole reason this page exists.
What Board & Batten Actually Is
Board and batten siding is built from two elements: wide flat panels (or boards) installed first, followed by narrower strips called battens that cover the vertical seams between them. The battens do double duty — they hide the joint and they create the shadow-line rhythm that gives the style its character. Reverse board and batten flips the order, with the wide panel proud of the narrower boards, giving a flatter look with less pronounced shadow lines.
In James Hardie's system, this is built with HardiePanel vertical siding as the field panel and HardieTrim boards as the battens, all factory-finished in ColorPlus so the panels and battens match exactly and the color is baked on before the material ever reaches Anacortes. That consistency matters more on board and batten than almost any other siding style, because the eye reads the vertical lines and joints immediately — any mismatch in sheen or tone stands out.
Board & Batten vs. Reverse Board & Batten
- Board and batten: narrow battens proud over wide panel joints — the classic farmhouse look, strong vertical shadow lines.
- Reverse board and batten: wide boards proud, narrow gaps recessed — a flatter, more contemporary read.
- Mixed elevation: board and batten on gables or an entry feature, lap siding on the rest of the house — common on Anacortes remodels where the goal is an accent, not a full re-side.
Why the Material Behind the Look Matters So Much Here
Skagit County's climate is not brutal in the way a hurricane zone or a deep-freeze climate is brutal. It's brutal in a slower, more patient way. Long stretches of damp, overcast weather. Salt-laden air drifting in off the water. Rain that comes in sideways during a fall or winter blow. Moss and algae that will colonize any surface that holds moisture, especially on north-facing walls and anything shaded by fir trees, which describes a lot of lots around here.
Board and batten's extra seams and extra fastening points make the choice of material more consequential than it would be on a plainer wall. A few examples of how that plays out:
- Wood-based panels (spruce, engineered wood, some LP-style products) rely on a factory or field-applied coating to keep moisture out of the wood fiber. Once a batten edge or a cut end is exposed — from a nail split, a caulk failure, or just normal weathering — moisture can wick into the substrate and the panel starts to swell or delaminate from the inside out, often invisibly until the paint is bubbling or the batten is soft.
- Vinyl board and batten is installed with expansion gaps and hung, not fastened tight, which is fine for vinyl's job but means it can rattle in a strong wind off the water and it will visibly fade and chalk faster in UV and salt exposure than a factory-baked finish.
- Fiber cement (James Hardie) is cement, sand, and cellulose fiber — there's no wood fiber to rot and no significant thermal movement to fight the fasteners. It doesn't feed moss the way wood substrates can, and it holds a factory finish for the length of the warranty instead of relying on field-applied paint or coating.
Comparing the Common Board & Batten Materials
| Material | Moisture behavior | Finish durability | Best fit for this climate |
|---|---|---|---|
| James Hardie fiber cement | No wood fiber to rot; won't swell or delaminate from moisture exposure | ColorPlus factory finish, warranted against fading/chipping/peeling | Engineered for it — this is why we install it |
| Engineered wood / LP-style panels | Wood-based substrate; depends on coating integrity at every cut and seam | Factory finish, but wood substrate is the failure point, not the paint | Workable if flashed and maintained perfectly, forever |
| Vinyl board & batten | Won't rot, but hangs loose and can be pushed by wind-driven rain at seams | Fades and chalks with UV/salt exposure over time, no re-coat option | Lowest cost, lowest long-term performance in this exposure |
| Primed spruce / cedar boards | Solid wood; needs a continuous field-applied finish to stay sealed | Depends entirely on repaint schedule and quality of application | Requires the most ongoing owner maintenance |
Where Board & Batten Installations Actually Fail
Most board and batten problems we get called to look at aren't material problems, they're installation problems that any material would eventually expose. This is a style where the install matters as much as the product:
- Batten fastening. Battens have to be fastened into the field, not just into the panel, following the manufacturer's blocking and fastener pattern. Fasten only into the thin batten without solid backing and you get a batten that works loose in the first few years of wind exposure.
- Vertical joint flashing. Every horizontal panel joint on a board and batten wall needs proper flashing and coursing behind it, not just a bead of caulk. Caulk is a wear item; flashing is the actual water management.
- Rainscreen gap. Because board and batten sits proud in places and tight in others, drainage behind the panel needs a clear path down and out. Skip the rainscreen furring and water that gets behind the cladding — which it eventually will, on any siding — has nowhere to go but into the wall assembly.
- Bottom termination. The bottom edge where board and batten meets the foundation or a lower roofline needs a drip edge and clearance off any horizontal surface. Set it too tight and it sits in splashback and standing moisture through every wet Skagit County winter.
James Hardie's Board & Batten Product Lines
James Hardie builds their products in different formulations for different climate zones under their HZ5 engineered system, and the Pacific Northwest formulation is built around the moisture and moss conditions this region actually sees rather than a national average. For board and batten specifically, the relevant products are:
- HardiePanel vertical siding — available in Select Cedarmill (subtle wood grain) or Smooth finish, used as the field panel behind the battens.
- HardieTrim boards — used as the battens themselves, factory-finished to match or contrast with the panel color.
- ColorPlus Technology — the factory-applied finish system used across both, which is what gives the panel and batten color consistency and the extended finish warranty.
Color and Shadow-Line Decisions Worth Thinking Through
Board and batten's whole visual payoff is the shadow line the battens cast, so color choice interacts with that more than it does with flat lap siding.
- Same-color panel and batten lets the shadow lines do all the work — a cleaner, more architectural look that reads well against Anacortes's evergreen and water backdrop.
- Contrasting batten color emphasizes the grid pattern itself, which reads more traditional-farmhouse and can work well as an accent on a gable or entry rather than a whole elevation.
- Darker colors show shadow lines more dramatically but also show dust, pollen, and any moss growth more readily on north-facing walls — worth weighing against your lot's shade and exposure.
What a Correct Board & Batten Install Looks Like, Step by Step
- Remove existing siding down to the sheathing and assess for any hidden moisture damage before covering it back up.
- Repair or replace damaged sheathing; this is the point where problems get fixed, not sealed in.
- Install a weather-resistive barrier per code and manufacturer instructions, lapped correctly at every seam.
- Install vertical furring strips to create a drainage gap behind the panels — non-negotiable in a climate this wet.
- Flash all windows, doors, and horizontal joints before panels go up, not around them afterward.
- Install HardiePanel field panels per Hardie's fastening schedule.
- Install HardieTrim battens over the panel joints with fasteners driven into solid backing at the specified spacing.
- Caulk and seal per manufacturer spec at trim intersections only — caulk is a supplement to flashing, never a substitute for it.
- Final inspection of fastener pattern, gaps, and clearances before calling the job done.
What This Means for Your Home in Anacortes
Whether board and batten is the right call for your house comes down to the look you want and how much long-term maintenance you're willing to sign up for. If you want the vertical-line look with the least ongoing upkeep, factory-finished fiber cement is the version of board and batten that's actually built for salt air and a moss-friendly climate rather than fighting it. If you're set on a wood look, going in with eyes open about the coating maintenance that comes with it is fair — we'll tell you honestly what that commitment looks like rather than talk you into something we won't stand behind.
If you're weighing board and batten against a full re-side, or trying to figure out whether it makes sense as an accent on your home versus the whole exterior, we're happy to walk the house with you and talk through the real trade-offs.
