Lynden Siding Roofs on the Border Take a Different Kind of Beating
Homes near the Aldergrove border crossing sit in an odd little climate pocket. You're close enough to the Strait of Georgia and Puget Sound to get salt-tinged, moisture-heavy air moving through on the prevailing westerlies, but far enough inland and up against the foothills that wind gusts funnel and swirl instead of blowing through cleanly. Add a wet season that stretches from October well into May, and a roof here is working overtime almost year-round. We service this stretch of the Lynden–Aldergrove corridor regularly, and the storm damage patterns we see are consistent enough that we can usually tell you what's wrong before we're even off the ladder.
This page is specifically about storm damage roof repair for homes in and around Aldergrove, BC — not a general roofing overview. If a windstorm, hailstorm, or heavy winter system has left you with missing shingles, a leak, or debris damage, here's what actually needs to happen to fix it right.
What Storm Damage Actually Looks Like Here
Most storm damage in this area isn't dramatic. It's rarely a tree through the roof. More often it's the kind of damage that's easy to miss from the ground and easy to underestimate once you do spot it:
- Shingles lifted or creased at the tab by wind gusts, then not resealing properly once the weather calms
- Shingles or ridge caps blown off entirely, leaving a bare strip of exposed underlayment or decking
- Granule loss from wind-driven rain and hail, showing up as bald or discolored patches
- Flashing pulled loose around chimneys, vents, and skylights where wind gets underneath and works it back and forth
- Gutters and downspouts torn loose or clogged with storm debris, backing water up under the roof edge
- Moss mats loosened by wind and rain, pulling granules and shingle material with them as they slide
That last one is worth pausing on. Moss doesn't cause storm damage on its own, but a roof that already has a moss problem is far more vulnerable when a storm hits — the moss holds moisture against the shingle surface, softens the mat underneath, and gives wind something to grab onto. A storm often just finishes the damage moss started months earlier.
Why a Quick, Correct Assessment Matters More Than Speed
After a storm, the instinct is to get someone up there fast and get it patched before the next system rolls in. Speed matters, but a rushed assessment is how small problems get missed and turn into ceiling stains six weeks later. A correct storm damage inspection covers the whole roof system, not just the spot where the leak showed up inside:
What we check on every storm call
We walk the full roof plane, not just the area over the leak — wind damage is often worse a few feet away from where water actually found its way in. We check the decking underneath any missing or lifted shingles for soft spots or rot, since a shingle repair over damaged decking is a repair that fails again within a year. We inspect all flashing points — chimneys, plumbing vents, skylights, and roof-to-wall transitions — because these are where storm-driven water actually gets inside, far more often than through the shingle field itself. And we check the attic side when access allows, since staining, wet insulation, or daylight through the roof deck tells us things the exterior inspection can't.
What a Correct Repair Actually Involves
Not every storm-damaged roof needs a full replacement, and we're not going to tell you it does. But a repair that's done correctly involves more than nailing a few replacement shingles over the gap. The steps that matter:
1. Removing damaged material properly
Cracked, creased, or granule-stripped shingles get pulled, not just covered. A shingle that's structurally compromised will keep failing even if it looks fine from the driveway.
2. Checking and repairing the decking
Any decking exposed by missing shingles gets checked for moisture damage before anything goes back down. Soft or delaminated plywood gets replaced — patching over it just relocates the problem.
3. Restoring the underlayment
The underlayment is your actual water barrier; the shingles are largely wind and UV protection on top of it. Torn or missing underlayment gets replaced, not skipped, even though it's invisible once the job is done.
4. Reflashing where needed
If flashing was lifted or bent by wind, it gets resealed or replaced rather than just pressed back down and caulked. Caulk is a stopgap, not a repair.
5. Matching materials as closely as possible
We match shingle color, profile, and where possible manufacturer to the existing roof. An exact match isn't always available, especially on an older roof, and we'll tell you honestly up front if it isn't — better to know before the work starts than to be surprised after.
Repair vs. Replacement: How We Make That Call
This is the question every storm-damaged roof raises, and the honest answer depends on more than just how much of the roof is damaged.
| Factor | Leans toward repair | Leans toward replacement |
|---|---|---|
| Age of roof | Under 10–12 years | Approaching or past expected lifespan |
| Extent of damage | Isolated area, one or two slopes | Widespread across most of the roof |
| Decking condition | Solid, dry, no rot found | Soft spots or rot in multiple areas |
| Moss/algae history | Minimal or recently treated | Long-term buildup, mats in multiple areas |
| Shingle match availability | Close match found | No reasonable match, patchwork look likely |
| Insurance scope | Adjuster approves repair scope | Adjuster or contractor documents full-slope loss |
We'll walk you through where your roof falls on that table honestly. A repair that will genuinely hold is always the cheaper and less disruptive option, and we'd rather do the smaller job right than talk anyone into a replacement they don't need. But we'll also tell you plainly when a repair is just delaying an inevitable replacement, because that's information you need to plan around, not a surprise for later.
Insurance and Documentation
Most storm damage repairs in this area involve a homeowner's insurance claim, and how the damage is documented matters almost as much as how it's repaired. Before any repair work starts, we photograph the damage as we find it — not staged, just what's actually there: lifted shingles, exposed decking, damaged flashing, granule loss patterns. That documentation is what supports your claim if an adjuster's initial estimate comes in low or misses damage that isn't visible from the ground.
We're not a public adjuster and we don't represent your insurance company or you in a claim dispute. What we will do is give you a straightforward, itemized scope of the actual repair work needed, so you're working from an honest number rather than guessing at what a fair estimate looks like.
Why It Matters That We Already Work This Border Corridor
Aldergrove sits right at one of the more frequently used crossings between Whatcom County and British Columbia's Fraser Valley, and homes on both sides of that line deal with the same weather systems moving through in the same week. A crew that already routes through this area for other jobs can get to a storm-damaged roof faster than one that has to plan a special trip, and that matters when a tarp needs to go up before the next front rolls in.
Familiarity with the area also means we're not guessing at what's normal wear versus what's storm-caused when we show up. We've seen enough roofs on this stretch to recognize the difference between a slope that's simply due for replacement and one that took real damage from a specific event — which is a distinction that matters both for your repair plan and for your insurance claim.
What to have ready before we come out
- Rough date of the storm or weather event, if known
- Whether you've noticed any interior leaks, stains, or drips
- Photos of any visible exterior damage, taken safely from the ground
- Your insurance company's claim number, if you've already filed
- Roof age or install date, if you have it on hand
After the Repair: Keeping Moss From Undoing the Work
A repaired roof in this climate still faces the same long moss season every other roof here does. Moss thrives in exactly the conditions this region provides — shade, consistent moisture, and mild temperatures that never quite dry the roof surface out for long stretches. Left unmanaged, it works its way back in around the same spots that just got fixed.
A few habits go a long way after a storm repair: keep gutters clear so water isn't sitting against the roof edge, keep overhanging branches trimmed back so shaded, damp areas of the roof get some sun and airflow, and have the roof looked at once a year rather than waiting for the next obvious problem. None of that is complicated, but it's the difference between a repair that lasts and one that's undone by the same conditions that caused the original damage.
