Roof Repair in Burnaby, BC: Guide by Home Type | NuRoof
Burnaby looks like one city, but its roofs live in very different conditions. A townhouse near Metrotown, a 1960s house on Capitol Hill and a home on the slopes of Burnaby Mountain face different weather, different rules and different repair problems.
Burnaby's housing has also changed fast. Single- and two-family homes made up about 42% of the city's housing in 1996 and about 22% by 2021, according to the City. Most Burnaby homeowners now live in townhouses, low-rises and other multifamily buildings, where the first question about a roof leak is often "who's responsible?"
This guide is organized the way Burnaby is: by the kind of home you own, the part of the city it's in, and the time of year. It covers what typically goes wrong, what you're responsible for, the permit and tree rules that apply, and a season-by-season checklist to keep small problems from becoming big ones.
Roof repair by Burnaby home type
Home type | Most common roof problems | Who usually arranges the repair |
|---|---|---|
Older detached house (1950s–1970s) | Aging chimney flashing, multiple re-roof layers, worn vent boots, rot at the eaves | You |
Newer detached house or duplex | Shingle wind damage, valley leaks, skylight seals | You (check any builder or new-home warranty first) |
Townhouse or rowhouse in a strata | Leaks at shared walls and roof-to-wall joints, clogged shared gutters, moss on shaded rows | Usually the strata corporation |
Flat or low-slope roof (additions, garages, laneway homes, modern builds) | Seam failures, blocked drains, ponding water | You, or the strata if it's common property |
Older detached houses
Many of Burnaby's single-family homes date from the post-war decades. Their roofs have often been re-shingled more than once, sometimes with a new layer laid over the old one. Extra layers add weight and trap moisture, and they hide problems in the deck underneath. Chimneys are the other weak point: as mortar ages, the counter-flashing that seals the chimney to the roof pulls away and lets water in. If your home is in this group, a repair often starts with checking how many layers are up there and what condition the deck is in.
Townhouses and stratas
Townhouse rows have long, continuous roofs with many joints where one unit meets the next, where roofs meet walls, and where dormers break the line. Those joints are where leaks start. Because the roof is usually common property, the strata corporation is normally responsible for repairing it. Report a leak to your council or property manager in writing, with photos and dates, before calling a roofer yourself. Some stratas designate roofs as limited common property, so check your bylaws.
Flat and low-slope roofs
Flat roofs are common on Burnaby additions, garages, laneway homes and newer infill. They are sealed with membranes such as torch-on (SBS) and fail in predictable places: seams, drains and anywhere water sits after rain. Keep drains and scuppers clear in the fall. Torch-on work involves open flame, so ask any roofer how they manage fire safety and whether they carry insurance for torch work.
Higher ground: Burnaby Mountain and the hills
Burnaby rises from the Fraser River flats to the top of Burnaby Mountain, and the weather changes on the way up. Simon Fraser University notes that Burnaby Mountain gets more than 50 cm of snow a year, mostly from December to March, and its cooler temperatures turn rain to snow more often than in the lower city.
For homes on the mountain's slopes and other high ground, that means:
Snow sitting on the roof. Heavy wet snow adds load and can hide damage until it melts.
Freeze-thaw cycles. Water that gets under a lifted shingle can freeze, expand and widen the gap.
Ice at the eaves. Where heat escapes through the roof, melted snow can refreeze at the cold edge and back water up under the shingles. Better attic insulation and ventilation fix the cause; the roof repair fixes the symptom.
If you're on higher ground, check the roof and gutters after the first real snowfall, not just after rain.
Trees, roofs and the Burnaby tree bylaw
Burnaby is a green city, and big conifers and maples are a major cause of roof wear. Overhanging branches scrape shingles in the wind, drop needles that clog gutters and valleys, and shade the roof so moss can take hold.
Before you remove a tree that is damaging your roof, check the Burnaby Tree Bylaw. For most residential lots, the City treats any conifer 30 cm (12 inches) or more in diameter, and any deciduous tree 45 cm (18 inches) or more, as a protected tree that needs a tree cutting permit to remove. Lots under a development application have a lower threshold of 20 cm. Other trees can be protected too, such as those in streamside areas or under a covenant.
The City's tree page doesn't spell out the rules for pruning, so call the City's tree line before cutting back large branches, or hire a certified arborist who knows the bylaw. Trimming branches back from the roof is often enough to stop the damage without removing the tree.
A season-by-season roof checklist for Burnaby
Season | What to do | Why it matters in Burnaby |
|---|---|---|
Early fall (Sept–Oct) | Clean gutters and flat-roof drains, book a roof inspection, fix anything found | The last dry window before rain sets in for the winter |
Late fall (Nov) | Walk around the house after each storm; check the attic after heavy rain | November is one of the wettest months in the region |
Winter (Dec–Feb) | Check for lifted or missing shingles after windstorms; on high ground, watch for ice at the eaves | Windstorms and snow on Burnaby Mountain and the hills |
Spring (Mar–May) | Treat moss, clear needles from valleys and gutters, look for winter damage | Moss grows through the mild, damp winter |
Summer (Jun–Aug) | Schedule bigger repairs and replacements; trim branches back from the roof | Dry weather gives the best conditions for roofing work |
Do you need a permit for roof repair in Burnaby?
The City of Burnaby says minor, non-structural repairs to the outside of your home don't need a permit, which covers most small roof repairs. Repairs to restore a roof after a fire, flood or other disaster do need a building permit, and work that alters the structure generally does too.
If you're not sure, the City recommends contacting its Building Department before you start. A reputable roofer will also tell you whether your job needs a permit.
What roof repair costs in Burnaby
Most residential roof repairs in Burnaby cost a few hundred dollars to about $1,500, in line with the rest of the Lower Mainland. Shingle and vent boot repairs sit at the lower end; skylights, flat roofs and repairs that uncover rotted decking cost more. For a full breakdown by repair type, see our guide to roof repair costs in Vancouver; Burnaby pricing is similar.
Two things push Burnaby repairs up: multi-layer roofs on older houses, where the old layers may need stripping, and townhouse rows, where access and coordination with the strata add time.

Frequently asked questions
I live in a Burnaby townhouse. Who pays to fix the roof?
In most stratas the roof is common property, so the strata corporation is responsible for repairs. Report the leak to your council or property manager in writing, with photos. Some stratas designate roofs as limited common property, so check your bylaws.
Do I need a permit to repair my roof in Burnaby?
Minor, non-structural exterior repairs generally don't need one. Repairs after a fire, flood or other disaster, and structural changes, do. If you're unsure, contact the City of Burnaby's Building Department before starting.
Can I cut down a tree that's damaging my roof?
Possibly not without a permit. On most lots, conifers 30 cm or more in diameter and deciduous trees 45 cm or more are protected under the Burnaby Tree Bylaw. Trimming branches back from the roof often solves the problem. Check with the City or a certified arborist first.
Does snow on Burnaby Mountain damage roofs?
It can. Heavy wet snow adds load, freeze-thaw cycles widen small gaps, and ice at the eaves can back water under the shingles. Check the roof and gutters after the first big snowfall.
My older Burnaby house has two layers of shingles. Can you repair it?
Usually yes for a small area, but multiple layers hide the condition of the deck and add weight. If the roof is near the end of its life, stripping it to the deck and re-roofing is often the better long-term fix.
When should I book roof work in Burnaby?
Inspections and repairs in early fall, before the heavy rain. Bigger repairs and replacements in summer, when it's dry. Leaks still get fixed in winter: the area can be tarped in a storm and repaired in the next dry spell.
