If you live in Surrey, Delta, Langley, or anywhere in the Fraser Valley, you already know what’s coming: months of steady rain. Fall is the best time to get ahead of it. A quick fall roof and gutter inspection — done yourself or with a professional — can catch small problems before the wet season turns them into expensive repairs.
Home inspections in Surrey this time of year almost always include roof and gutter condition, because water intrusion is one of the most common issues found in Lower Mainland homes. Here’s what to check, what to watch for, and when to call in a professional.
Why Fall Is the Critical Window for Roof Checks in the Lower Mainland
The Fraser Valley’s rainy season typically runs from October through March. Roofs, gutters, and drainage systems take the heaviest punishment during these months. Damage that started during the dry summer — cracked flashing, lifted shingles, clogged gutters — may not show symptoms until the first sustained rainfall.
Catching these issues in October or November gives you a window to make repairs before winter weather makes roof work difficult or unsafe. It can also protect you when buying: fall inspections frequently reveal roof and gutter defects that become negotiating points between buyers and sellers.
What to Check on the Roof
You can spot many roof problems from the ground with a pair of binoculars — no ladder required.
- Missing, cracked, or curling shingles. Wind and summer heat can loosen or crack shingles. Curled edges are often a sign of an aging roof.
- Damaged or missing flashing. Flashing around chimneys, vents, and valleys is a common leak point. If it looks lifted, rusted, or separated, water can get in.
- Moss and algae growth. Moss is especially common on roofs in the Fraser Valley’s damp climate. It can lift shingles and trap moisture against the roof surface.
- Sagging areas. Any visible dip or sag in the roof line can indicate a structural issue and should be evaluated by a professional.
- Debris buildup. Leaves, branches, and needles trap moisture and add weight. Clearing debris off the roof surface helps it drain properly.
If your roof is more than about 15–20 years old, or you see several of these signs at once, a professional roof assessment or full home inspection is worth considering before the rains set in.
What to Check in the Gutters and Downspouts
Gutters are your roof’s drainage system. When they fail, water goes where it shouldn’t — behind siding, into the attic, or pooling against the foundation.
- Clogs and standing water. Scoop out leaves and debris. After a rain, check whether water sits in any section instead of flowing to the downspout.
- Sagging or detached gutters. Gutters should slope slightly toward downspouts. Sections pulling away from the fascia can indicate rotten fascia boards or failed fasteners.
- Leaks at seams and corners. Drips at joints during rainfall often mean seals have failed. These are usually straightforward to repair.
- Downspout discharge. Downspouts should carry water at least 4–6 feet away from the foundation. Extensions or splash blocks can help if water pools near the house.
- Overflow during heavy rain. If water sheets over the gutter edge during a downpour, the gutters may be undersized, clogged, or improperly sloped.
While you’re at it, check that the ground around your home slopes away from the foundation. Poor grading combined with clogged gutters is a common recipe for basement or crawlspace moisture.
Check the Attic Too
The attic tells the story of what’s happening under the roof. A quick fall attic check can reveal problems long before they show up on your ceilings.
- Water stains or dark spots on rafters, sheathing, or insulation — these can indicate an active or past roof leak.
- Damp or compressed insulation — wet insulation loses much of its insulating value.
- Daylight showing through the roof boards — visible light can mean gaps around vents, flashing, or damaged sheathing.
- Ventilation. Attics need airflow to move moisture out. Blocked soffit vents or a missing ridge vent can trap humidity and encourage mold growth, especially in older Surrey and Delta homes.
If you find stains or moisture in the attic, note where they are and have them evaluated — the source of the leak can be tricky to trace from the outside.
Fall Maintenance Beyond Roof and Gutters
While you’re in fall maintenance mode, a few extra checks can save trouble later:
- Trim overhanging branches. Limbs rubbing against the roof damage shingles and drop debris into gutters.
- Check exterior caulking and seals. Gaps around windows, doors, and penetrations let water in and heat out.
- Test the furnace or heating system before the first cold snap, and consider replacing filters.
- Inspect the crawlspace (if you have one) for standing water, musty odours, or damaged vapour barriers — moisture problems often start there.
When to Call a Home Inspector
A DIY walkthrough is a great start, but some situations call for a professional set of eyes:
- You’re buying a home this fall and need a full inspection before subject removal.
- Your roof is aging or showing multiple issues and you want an objective assessment.
- You’ve noticed stains, musty smells, or unexplained moisture inside the home.
- It’s simply been a few years since the home was professionally inspected.

FAQ
How often should I have my roof inspected in the Fraser Valley?
A visual check each fall and spring is a good habit for homeowners. A professional inspection is typically recommended before buying a home, and again every few years for aging homes or after major storm events.
Do clogged gutters really cause foundation problems?
They can. When gutters overflow, water pools near the foundation instead of being carried away. Over time this can contribute to basement or crawlspace moisture and soil erosion around the home.
Can moss on the roof cause damage?
Yes. Moss holds moisture against shingles and can lift them over time, creating pathways for water. On roofs in the Lower Mainland’s damp climate, moss removal is a routine part of roof maintenance.
What does a fall home inspection typically cost?
Inspection fees vary based on the size, age, and type of the home. For a current quote, it’s best to contact an inspector directly with your home’s details.
Should I get a home inspection if I’m not buying or selling?
Yes. Periodic inspections help homeowners catch maintenance issues early, plan for future repairs, and protect the home’s value — fall is an ideal time to schedule one before the rainy season.
Get Your Home Ready for the Rainy Season
Don’t wait for the first leak to find out what’s wrong with your roof and gutters. If you’re buying a home this fall, or you just want peace of mind before the wet months arrive, a professional inspection can identify issues while there’s still time to act.
