Storm Damage in Custer: What Our Climate Does to a Roof
Custer sits in the open, low-lying part of Whatcom County north of Ferndale, close enough to Georgia Strait and Birch Bay that winter storms arrive with real push behind them. That push means driving rain that comes in sideways instead of straight down, and wind gusts strong enough to work under a shingle tab that's already lost part of its seal. Rain doesn't just land on a Custer roof in a storm like this — it gets driven up under laps and around flashing edges that would stay dry in a calmer, more sheltered location.
Salt air off the water is the second factor at work here. It doesn't corrode a roof overnight, but over years it speeds up rust on exposed fasteners, pipe boots, and metal flashing faster than you'd typically see twenty or thirty miles inland. A roof that's already a decade or more old and dealing with salt-accelerated corrosion is far more likely to fail in a storm, because the metal components meant to shed water at seams and penetrations are usually the first things to give out.
Then there's moss. Whatcom County's wet season runs long, and properties around Custer with fir or cedar cover stay shaded and damp well into what would otherwise be drying weather elsewhere. Moss holds moisture against the roof surface, works its way under shingle edges over time, and lifts tabs just enough that the next windstorm has something to grab onto. A good share of what gets called "storm damage" in this area actually started as slow moss damage that a storm simply finished off.

Signs Your Custer Roof Has Storm Damage
Some storm damage is obvious — a missing shingle, a branch through the deck, a gutter torn loose. Most of it isn't. Here's what we tell Custer homeowners to check after a hard blow, from the ground and, if it's safe, from inside the attic:
- Shingles that look lifted, curled, or slightly out of line with the row around them
- Granules collecting in gutters or at the base of downspouts
- Bent, lifted, or missing flashing around chimneys, vents, and skylights
- New water staining on ceilings or in the attic, even a small brown ring
- Daylight visible through the roof deck from inside the attic
- Gutters pulled away from the fascia or sagging after heavy rain
- Moss that's suddenly thicker or that shifted position after wind
- Soft or spongy spots underfoot when the roof is walked (we check this, not homeowners)
If any of these show up, the priority is stopping water from getting further into the roof assembly, not waiting to see if it gets worse. A small leak caught early is a patch. The same leak ignored through another storm cycle can mean wet decking, wet insulation, and interior repair stacked on top of the roof work.
What a Correct Storm Damage Repair Actually Involves
Inspection and Documentation First
Before any repair starts, we walk the roof and document what the storm actually did — not just the obvious spot, but the surrounding area, since wind damage rarely stays in one tidy patch. We photograph lifted or missing shingles, flashing condition, and any sign that water already reached the decking. That documentation matters for the repair itself, and if you're filing an insurance claim, it gives you a clear record of storm-caused damage versus wear that predates the storm.
Matching Materials and Flashing Details
A repair that just fills the hole isn't a correct repair. Shingles need to match existing course lines and, where possible, the product already on the roof, so the patch doesn't shed water differently than the surrounding field. Flashing is where most repeat leaks come from. If chimney, vent, or valley flashing was bent or lifted in the storm, it needs to be reformed or replaced and properly stepped and sealed — not just caulked over the top. Caulk laid over bad flashing is a short-term fix that tends to fail again in the next hard rain, especially with the salt exposure common in this area.
Checking the Decking and Underlayment, Not Just the Surface
If water made it past the shingles, we check the decking underneath before closing anything back up. Wet plywood or wet underlayment left in place under a new shingle patch just traps moisture and sets up rot that shows up later as a soft spot or a sagging roofline. On any repair where we suspect water reached the deck, we open it up, confirm the condition of the wood, and replace what's compromised before new roofing goes back down.
Repair or Replace? How We Help You Decide
Not every storm-damaged roof needs a full replacement, and we don't push one when a proper repair will hold. The honest answer depends on a handful of factors we walk through with you on site:
| Factor | Points Toward Repair | Points Toward Replacement |
|---|---|---|
| Roof age | Under 10–12 years, otherwise sound | Already near or past its expected service life |
| Extent of damage | Isolated to one slope or area | Spread across multiple slopes or from repeated storm hits |
| Decking condition | Dry, solid wood found under the damaged area | Soft, delaminated, or rotted decking found |
| Material match | Existing shingle line still available or a close match exists | Product discontinued; a patch would be visibly mismatched |
| Moss and salt exposure | Surface-level, hasn't reached fasteners or deck | Long-term corrosion or rot found during inspection |
We'll show you where your roof lands on that list before recommending anything, and we'll say so plainly if a repair is the right call even when a replacement would be the bigger job for us.
Our Process, Start to Finish
- Call and initial assessment — we get a description of the damage, and for active leaks, prioritize getting someone out quickly.
- On-site inspection — a full walk of the roof, an attic check where accessible, and photo documentation of everything storm-related.
- Written scope and estimate — a clear description of what's damaged, what needs to happen, and a straightforward cost range before any work starts.
- Temporary protection if needed — for active leaks or exposed decking, we get a tarp or temporary cover in place so damage doesn't spread while materials are sourced.
- The repair itself — matching shingles, flashing work, and any decking replacement, done to hold up to the next storm rather than just pass a visual check.
- Cleanup and walkthrough — the site cleared of debris and old material, and we walk the finished repair with you so you know exactly what was done and why.
Working With Your Insurance Company
Most storm damage claims come down to documentation. Insurers want clear evidence that damage is storm-caused and recent, not gradual wear that's been building for years. Our inspection photos and written scope are built to support that conversation directly. We're not a public adjuster and we don't negotiate your claim for you, but we'll give you an honest, detailed account of what we found on your roof so you're not walking into that conversation with guesswork. If an adjuster's estimate misses something we documented — a section of damaged flashing, or decking that needs replacing — we'll point it out plainly so you can raise it.
Why a Crew That Already Works in Custer Makes a Difference
A contractor already working roofs in Custer and around Ferndale knows what these houses are dealing with without relearning it on your roof. We know which roof types and ages are common out here, how far moss tends to travel under the tree cover typical of this part of Whatcom County, and how wind off the water tends to hit a roof compared to a more sheltered inland site. That local familiarity means less time spent diagnosing the problem and more time spent actually fixing it.
It also means faster response. When a storm moves through and Custer takes damage, we're not driving in from out of the area with a backlog of jobs somewhere else ahead of yours — we're already local, working these same conditions on a regular basis. For an active leak, that difference in response time can be the difference between a contained repair and a much bigger interior mess.
After the Repair: Keeping Moss and Salt Air From Causing a Repeat
A repair holds a lot longer if the conditions that caused it are addressed too. A few things worth doing after any storm repair on a Custer roof:
- Keep gutters and downspouts clear so water has somewhere to go besides under the shingles
- Trim back tree limbs that keep sections of the roof shaded and damp longer than the rest
- Treat or remove heavy moss growth before it works its way back under shingle edges
- Check exposed metal flashing and fasteners periodically for early corrosion, especially on roofs facing open water or farmland
- Have the roof looked at after any major windstorm, even if nothing looks obviously wrong from the ground
None of that is expensive or complicated, but it's the difference between a repair that lasts and one you're calling us back about within a year.
If a recent storm left you with a leak, missing shingles, or just questions about what shape your roof is really in, we're glad to come take a look. The estimate is free, there's no pressure to move forward, and you'll get a plain answer about what's actually going on with your roof.
