How much does a new roof cost in Surrey BC?
$10,000–$18,000 for a standard Surrey detached home (1,500–2,500 sq ft) with architectural asphalt shingles, full tear-off, and all flashings. Metal roofing for the same home runs $22,000–$38,000. Townhouses from $7,500. See our full cost guide.
How long does a roof last in Surrey BC?
Architectural asphalt shingles last 22–32 years in Surrey’s climate with maintenance. Metal roofing lasts 40–60 years. Cedar shake lasts 18–28 years without regular treatment. See our complete roof lifespan guide.
Do I need a permit for a roof replacement in Surrey BC?
Yes, in most cases. The City of Surrey requires a building permit for full roof replacements. I-M Roofing handles the permit application as part of the project. See our roofing permit guide for Surrey BC.
How long does roof replacement take in Surrey?
1–2 days for most Surrey homes. Small homes in one day. Large or complex rooflines may take 2–3 days. Weather is the main variable in Surrey. See our timeline guide.
Should I repair or replace my Surrey roof?
If your roof is under 15 years old with isolated damage, repair is usually right. If it’s 20+ years old with widespread granule loss or multiple areas of damage, replacement is more cost-effective. Use the cost threshold rule: if repair costs more than 30% of replacement cost on a 10–15 year roof, replace. See our 7-point repair vs replacement guide.
How often should gutters be cleaned in Surrey BC?
Minimum once per year (November/December) for low-canopy properties. Twice yearly for moderate canopy. The November clean is most critical — clears fall leaf accumulation before Surrey’s heaviest winter rain. See our gutter cleaning guide.
What is soft-wash roof cleaning and why is pressure washing bad for shingles?
Soft-wash uses low-pressure application of biodegradable biocide to kill moss at the root without damaging shingles or removing granules. Pressure washing physically strips granules off asphalt shingles and voids all major manufacturer warranties. Never hire a contractor who pressure washes asphalt shingle roofs. See our moss removal guide.
What is the difference between re-roofing and full tear-off?
Re-roofing (lay-over) installs new shingles directly over the existing layer. Full tear-off removes everything down to the decking first. BC Building Code allows maximum 2 layers total — if you already have 2 layers, tear-off is legally required. Most manufacturer warranties are void on re-roof installations. See our re-roofing vs tear-off guide.
What does a roofing inspection cost in Surrey BC?
$150–$250 for a full residential inspection with written report and photos. Pre-purchase inspections (real estate) are $200–$300 and include a damage cost estimate for negotiation. See our inspection service page.
Is there a best time of year to replace a roof in Surrey BC?
June through September is ideal (driest, longest days). September and October are excellent — still dry, cooler working conditions, and faster crew scheduling than peak summer. November through March requires more weather-window flexibility but is manageable with experienced Surrey roofers who track 7-day forecasts.
Does a new roof increase home value in Surrey?
Yes. A new roof typically prevents $8,000–$15,000 in buyer credit requests for an aging roof, and improves listing appeal. Returns approximately 60–80% of replacement cost in improved offer price in Metro Vancouver’s market.
What warranty should I expect from a Surrey roofing company?
Minimum 5-year workmanship warranty from any reputable Surrey roofer. I-M Roofing provides 10 years on all full replacements. Manufacturer warranty (25–50 years, prorated) applies when a full tear-off installation uses registered brand shingles. See our warranty guide.
