B.C. roof maintenance should follow the seasons because the risks change through the year. Coastal homes need to prepare for prolonged fall/winter rain, while Interior and northern homes also need snow, ice and freeze-thaw monitoring. The goal is not constant roof work—it is catching small changes at the right time.
What is the complete B.C. roof maintenance calendar?
| Season | Main roof priorities |
|---|---|
| Spring | Check winter/storm damage, clear drainage, inspect flashings and document changes. |
| Summer | Complete planned repairs, manage moss/debris, check attic ventilation and prepare capital work. |
| Fall | Clean gutters/valleys, confirm downspout flow, inspect roof edges and prepare for heavy rain. |
| Winter | Monitor leaks, attic moisture, snow load, ice dams and storm damage without unsafe roof access. |
RCABC's maintenance guidance recommends competent roof inspections at least twice yearly—spring and fall—plus extra inspections after major storms or construction activity that could affect the roof.
Spring: what should you inspect after winter?
- look for missing, lifted or cracked shingles from winter wind;
- check gutters and downspouts for winter debris;
- look for bent or loosened flashing and roof-edge metal;
- inspect ceilings and attic areas for stains or condensation evidence;
- note moss growth, branches and debris that retained moisture;
- check low-slope drains and scuppers where accessible.
RCABC explains that spring inspection is useful because it reveals possible winter damage and gives time to complete repairs in better weather. GAF's homeowner spring checklist likewise emphasizes gutters, flashing and shingle condition.
Summer: what roofing work is best done in dry weather?
Summer is a practical time for planned repairs and maintenance that need dry surfaces or predictable weather. Priorities can include:
- repairing flashing defects identified in spring;
- replacing localized damaged roofing;
- removing debris and managing moss using roof-safe methods;
- checking attic intake/exhaust pathways;
- reviewing roof age and replacement budgets before fall;
- completing chimney, skylight or gutter repairs while conditions are stable.
If attic heat or condensation has been a concern, see how attic ventilation affects roof life.
Fall: how should you prepare the roof for B.C. rain?
Fall is the highest-value maintenance window for many coastal properties. CMHC's seasonal home-maintenance guidance recommends clearing leaves from eavestroughs and roofs and testing downspouts so roof water drains properly.
- clear gutters, outlets, valleys and downspouts;
- check that downspout discharge routes are open;
- remove heavy needle or leaf accumulation from roof surfaces;
- inspect flashing at chimneys, skylights and wall transitions;
- look for cracked sealants or displaced roof-edge metal;
- confirm emergency contact information before storm season.
If clean gutters still overflow, use the guide on what causes gutters to overflow during B.C. rainstorms.
Winter: what should homeowners monitor?
Winter maintenance is mostly observation rather than roof walking. Watch for:
- new ceiling stains or drips during rain;
- attic condensation, frost or damp insulation;
- ice dams or unusual snowmelt patterns in colder regions;
- large branches resting on the roof;
- gutters or downspouts blocked by ice;
- visible roof damage after high winds.
CMHC's winter guidance recommends monitoring homes for excess moisture and checking attics for frost accumulation, roof ice dams or icicles. For cold-region prevention, see ice-dam prevention for Interior and Northern B.C.
What should you do after a major storm?
Do an event-driven check after unusual wind, falling branches, extreme rain, hail or heavy snow. RCABC recommends extra inspections after major storms because roof conditions can change between normal spring/fall cycles.
From a safe location, document missing shingles, displaced flashing, damaged gutters, debris impact and new interior stains. For major wind events, use what to do immediately after a B.C. windstorm.
Do tree-covered and moss-prone homes need a different schedule?
Yes. Homes beneath mature trees may need more frequent gutter, valley and roof-surface checks because needles and leaves can accumulate quickly. Shaded north-facing slopes can also remain damp longer and support moss growth.
Increase observation frequency during heavy leaf/needle drop rather than waiting for one annual cleaning. Keep the focus on drainage and drying—not aggressive roof washing.
When should you schedule a professional roof inspection?
Professional inspection is useful when:
- the roof is entering the later part of its expected life;
- you find recurring stains or leaks;
- the roof experienced major wind or impact;
- safe access is not possible;
- you are planning repair versus replacement;
- you need documentation for a property sale, strata plan or capital budget.

Frequently asked questions
How often should a residential roof be inspected?
A seasonal ground-level homeowner check is useful, while professional frequency depends on age, exposure, symptoms and warranty requirements. Commercial guidance commonly uses spring/fall as a baseline.
When should gutters be cleaned in B.C.?
At minimum, inspect before the heavy fall/winter rain and again after major leaf or needle drop. Tree-covered homes may need more frequent cleaning.
Should I walk my roof to inspect it?
Not if it is wet, steep, icy, fragile or unfamiliar. Ground-level observations, attic checks and professional access are safer.
What roof maintenance is most important before winter?
Clear drainage, inspect flashings and roof edges, remove debris, address known leaks and confirm attic moisture/ventilation issues before colder weather.
Do I need an inspection after every storm?
No. Extra checks are most useful after unusually strong wind, major impact, extreme rain, heavy snow or when new symptoms appear.
Maintenance basis: RCABC's current roof-maintenance guidance recommends competent inspections at least twice yearly, in spring and fall, with extra inspections after major storms or roof-affecting construction. CMHC's seasonal guidance also recommends fall roof/eavestrough cleaning and winter monitoring for attic frost, ice dams and excess moisture.
