Bellingham Roofing Board & Batten Siding for Columbia Homes
Columbia is one of Bellingham's older, closer-in neighborhoods, and it shows in the housing stock: a mix of craftsman-era homes, mid-century infill, and newer builds sitting on the same blocks. Board and batten siding fits naturally into that mix. It reads as classic Pacific Northwest — clean vertical lines, strong shadow reveal, a look that works equally well on a century-old bungalow addition or a new build trying to fit in with its older neighbors. It's also a style choice homeowners in this part of Bellingham ask for specifically, whether as a full re-side or as an accent on gables, dormers, and entry features paired with lap siding elsewhere on the house.
What board and batten is not, though, is a forgiving style. The vertical boards and the battens that cover their seams create a lot of linear joint length compared to horizontal lap siding, and every one of those joints is a potential water path if the material or the installation isn't right. In a climate like Whatcom County's, that difference matters more than it would somewhere dry.
What Bellingham's Climate Demands From This Style
Salt Air Off the Bay
Columbia sits close enough to Bellingham Bay that homes in this neighborhood get a steady dose of salt-laden air, especially on west and south exposures. Salt air accelerates corrosion of fasteners and metal flashing, and it degrades paint and coatings faster than inland exposure would. On a board and batten wall, where dozens of extra fastener lines run down every batten, that adds up. Corrosion-resistant fasteners and a factory finish that's actually engineered to hold color and integrity in coastal air aren't optional extras here — they're the difference between a wall that looks good in year twelve and one that's chalking and staining by year five.
Driving Rain
Storms coming off the Salish Sea don't just fall straight down — wind pushes rain sideways into walls, and board and batten's vertical seams give wind-driven water more opportunities to find a way behind the cladding than a horizontal lap profile does. Every batten joint, every board end, every point where trim meets siding is a place water can be forced in under pressure, not just gravity.
A Long Moss Season
Bellingham's wet season runs long, and shaded north and east walls in tree-covered neighborhoods like Columbia stay damp for weeks at a stretch. That's exactly the condition moss and mildew need. Siding material that absorbs moisture, or a wall assembly that traps it against the substrate, turns that seasonal dampness into long-term rot risk instead of just a surface cleaning chore.
Why We Only Install James Hardie for This Style
We install James Hardie fiber cement exclusively — we don't offer board and batten in vinyl, LP SmartSide, primed wood, or cedar. That's not a marketing position, it's a practical one built around exactly the exposures described above. Fiber cement doesn't absorb water the way wood-based substrates can, so it doesn't swell, cup, or feed rot at the cut edges and joints that board and batten has so many of. It's non-combustible, which matters given how many Whatcom County homes back up to trees and brush. And Hardie's ColorPlus factory finish is baked on and warrantied against fading and flaking in a way field-applied paint on wood or engineered wood trim generally isn't — a real advantage when the air itself is working against the finish twelve months a year.
We're not going to tell you wood board and batten can't look beautiful, because it can. But it needs a maintenance commitment — recaulking, repainting, watching every joint for the first sign of moisture — that most homeowners underestimate until they're three years in. Hardie's HZ5 product line is engineered for exactly this Pacific Northwest exposure, and it's what lets us stand behind the work without asking a homeowner to become a part-time siding caretaker.
What a Correct Board & Batten Installation Actually Involves
The Rainscreen Gap
Board and batten should never go on flat against the weather-resistive barrier. A furred-out rainscreen gap behind the siding lets any water that does get past the battens drain and dry instead of sitting against the sheathing. Skipping this step is one of the most common shortcuts on vertical siding jobs, and it's invisible once the wall is closed up — which is exactly why it matters who's holding the nail gun.
Fastening and Batten Layout
Batten spacing needs to land on the panel joints underneath and on framing, not just wherever looks even from the ground. Fasteners need to be corrosion-resistant and driven to Hardie's specified pattern and depth — overdriven or underdriven fasteners are a leading cause of premature siding failure, board and batten included. Batten width and reveal should be consistent across the whole elevation, especially where it transitions to lap siding or trim.
Trim, Flashing, and Joints
Every horizontal joint, window head, and transition needs proper flashing integrated with the weather-resistive barrier, not just caulked over. Board and batten's vertical seams should be backed, not just butted and sealed, and joints should be planned to avoid stacking at weak points like window corners. This is the detailing work that separates a wall that sheds Bellingham rain for decades from one that's back on the repair list in five years.
Comparing Board & Batten Material Options
| Material | Moisture Behavior | Coastal/Salt Air Durability | Finish Life |
|---|---|---|---|
| James Hardie Fiber Cement | Does not absorb and swell; engineered HZ5 formulation for wet climates | Strong; non-combustible, corrosion resistance depends on fastener/flashing quality | ColorPlus factory finish, warrantied against fade and flaking |
| LP SmartSide / Engineered Wood | Wood-based; treated but still moisture-sensitive at cut edges and joints | Fair; more joint sealing and monitoring needed near the bay | Field or factory finish, shorter repaint cycles than fiber cement |
| Primed Wood / Cedar | Absorbs moisture readily; classic look but highest maintenance | Weakest in salt air and constant damp without diligent upkeep | Repaint or reseal every few years |
| Vinyl Board & Batten Profile | Doesn't rot, but relies entirely on drainage plane behind it | Can become brittle and fade; limited profile depth for true board and batten look | No repainting, but color is baked in and can't be refreshed |
Our Process for Columbia Homeowners
We start with an on-site walkthrough of the house, not just a measurement — looking at wall orientation, existing moisture damage, roofline and gutter interaction, and where the current siding is failing, if it's failing at all. For a full board and batten re-side, we plan batten layout and reveal against the actual elevation rather than a generic spec sheet. Where board and batten is being mixed with lap siding or trim accents, we plan the transitions before any material goes up so the seams land in sensible, low-stress locations.
Installation includes the rainscreen furring, corrosion-resistant fastening to Hardie spec, and integrated flashing at every horizontal break — window heads, transitions, and the base of the wall. We walk the finished job with the homeowner before we call it done, because board and batten's clean lines make sloppy fastening or uneven reveals obvious in a way lap siding sometimes hides.
Maintenance: What Board & Batten Actually Needs Here
- Rinse pollen, salt residue, and grime off the siding once or twice a year — a garden hose is enough, no pressure washer directly at joints or battens
- Walk the exterior each fall before the wet season and check caulking at trim and window transitions for cracking or gaps
- Keep gutters clear so overflow isn't running down the wall face, especially above board and batten sections
- Trim back branches and shrubs holding moisture and shade against shaded elevations to slow moss growth
- Watch north and east walls specifically for early moss or mildew and address it before it spreads across a full elevation
- Report any soft spots, staining, or bubbling paint near the base of the wall right away — early moisture is far cheaper to fix than rot
Why Hire a Crew That Already Works This Neighborhood
Board and batten done wrong doesn't usually fail in year one — it fails in year six or eight, quietly, behind a wall that still looks fine from the street. A crew that's worked Columbia and the rest of Bellingham knows which elevations take the worst of the wind-driven rain, which older homes have wall assemblies that need extra attention before new siding goes on, and how to detail a rainscreen and flashing system for a climate that doesn't give a wall many dry months to recover in. That's local experience you can't get from a national siding outfit rotating through on a install-and-leave schedule, and it's the difference between board and batten that holds up through Whatcom County winters and board and batten that becomes a callback.
