Why Roof Inspections Matter in Rainy Vancouver

How Vancouver’s rain, moss and coastal weather wear down roofs

Few cities punish a roof the way Vancouver does. Months of uninterrupted rain, constant moisture trapped under tree canopies, and wind-driven sideways storms create the perfect environment for early roof breakdown. Moss creeps into shingle edges. Algae stains spread across north-facing slopes. Flashings corrode faster in salt-influenced air drifting from the Strait. Even small weaknesses—an exposed nail, a lifted shingle tab—turn into leaks far faster here than in drier climates. Regular inspections are the only way to stay ahead of slow, weather-driven deterioration that Vancouver hides well until the damage is extensive. For a deeper look at how we structure these assessments, the Vancouver roof inspection page breaks down our full process.

Why “no visible leaks” doesn’t mean your roof is fine

A dry ceiling tells you nothing about what’s happening under the shingles. Vancouver homes often have leaks that soak plywood, rot rafters or saturate insulation long before any water ever reaches the drywall. Valley failures, chimney flashings, skylight cracks and wall tie-ins can leak internally for months—sometimes years—before a stain appears. In the attic, moisture can evaporate before it ever becomes visible inside the home. “No leaks” simply means “no symptoms you can see.” A proper inspection uncovers the hidden issues before they turn into structural or indoor air-quality problems.

How regular inspections extend roof life and prevent surprise costs

A roof typically doesn’t fail all at once. It fails in stages—granule loss, loose flashings, clogged valleys, early signs of rot, poor ventilation, moss buildup. An annual or bi-annual inspection catches these early markers so they can be corrected with minor repairs instead of waiting until a full replacement is unavoidable. In Vancouver’s climate, proactively maintaining the roof can add years of extra performance, postpone major expenses and dramatically reduce the risk of emergency leak events during atmospheric river storms.

12 Signs It’s Time to Call a Professional Roof Inspector in Vancouver

1. Missing, cracked or curling shingles after our winter or fall storms

Wind, heavy rain and freeze–thaw cycles loosening or curling shingles.

2. Granules in your gutters, downspouts or at the bottom of your driveway

Asphalt shingles shedding their protective layer faster than normal.

3. Dark streaks, moss and heavy algae growing on your roof

Persistent moisture on north-facing and tree-covered Vancouver roofs.

4. Water stains on ceilings or walls after heavy rain

“Mystery” stains that come and go with storms or long wet periods.

5. Peeling paint or moisture damage around skylights and chimneys

Failing flashings and sealants at high-risk penetration areas.

6. Sagging areas or soft spots you can feel when walking the roof

Potential rot in the plywood deck or long-term water saturation.

7. A hot, stuffy or musty-smelling attic

Poor ventilation, trapped moisture and possible mold risk.

8. Ice dams or frost buildup inside the attic in colder months

Heat loss, condensation and ventilation issues common in older Vancouver homes.

9. Rusted metal flashings, exposed nails or open seams

Small details that turn into major leaks in our coastal climate.

10. Old roofing nearing the end of its typical lifespan

Cedar, asphalt or torch-on systems that are “ageing out” even without leaks.

11. Recent storm, tree impact or construction near the roof

Windstorms, falling branches or trades walking the roof surface.

12. You’re buying or selling a home in Vancouver

DIY Check vs Professional Roof Inspection in Vancouver

What homeowners can safely look for from the ground

From the ground, you can safely check for obvious issues: missing shingles, visible sagging, moss-heavy patches, clogged gutters, detached downspouts and debris in valleys. Binoculars help you spot damaged flashing or exposed nails without climbing the roof. But beyond those surface clues, most problems lie where you can’t see them.

Why climbing steep, wet Vancouver roofs is risky

Vancouver roofs are rarely dry for long, and many neighbourhoods—Kits, Dunbar, North Shore, Renfrew—have steep pitches that get slick instantly in mist or drizzle. Mix in moss, algae or frost and the risk grows. Falls are one of the leading causes of homeowner injury. Even roofers rely heavily on fall protection, anchors and proper footwear here.

What a professional inspector sees that you can’t

A trained roofer knows where Vancouver roofs fail: sidewalls, step flashings, chimneys, valley metal, skylight frames, plumbing vents, dead valleys, parapets and penetrations. They know how moisture migrates inside attics, how insulation affects airflow, how bad flashing sequences look under shingles, and how to detect early rot. They’re not just looking at the roof—they’re reading the story of how the system has handled years of weather.

What Happens During a Professional Roof Inspection

Exterior inspection – shingles, flashings, valleys and penetrations

We walk the entire roof (if safe), checking material condition, installation quality, flashing integrity, open seams, membrane adhesion, fastener exposure and signs of aging or failure.

Attic inspection – insulation, moisture, ventilation and structure

Inside the attic, we look for staining, mold, frost, delamination, airflow blockages, bathroom fan venting issues, insulation coverage gaps and structural concerns. Attic inspection is often where the truth comes out.

Photos, notes and a clear report with repair or replacement recommendations

You receive a straightforward summary: what’s good, what’s failing, what needs attention soon, and what the expected lifespan looks like. With photos. With explanations. With zero pressure.

How Often Should You Schedule a Roof Inspection in Vancouver?

General guidelines for typical asphalt, cedar and flat roofs

• Asphalt shingles: every 1–2 years
• Cedar shakes: annually
• Flat/torch-on membranes: annually plus after heavy storms

Extra checkups after major storms or visible damage

Windstorms, falling branches, construction debris or a neighbour’s trades walking across your roof can create issues you won’t notice from the ground. A post-storm check prevents small damage from snowballing into full leaks.

Why older roofs and heavily treed lots need more frequent attention

Homes under constant shade—Kits, Renfrew, North Van, Shaughnessy—develop moss faster. Older roofs also deteriorate unevenly. Inspections catch failures before they spread.
