Tile Roof Replacement in Surrey BC — The Complete 2026 Conversion Guide

Your concrete tile roof is cracking. The manufacturer closed years ago. Replacement tiles do not exist. This guide covers everything Surrey homeowners need to know about converting old tile roofs to modern systems like asphalt shingles, metal, Enviroshake , Brava composite tile , or Euroshield rubber — including why we always deck with plywood and never OSB, real 2026 costs, and the exact process our team follows.

Why Surrey’s Concrete Tile Roofs Are Failing

The tiles look fine from the driveway. That is the problem.

Concrete tile was designed for Mediterranean coastlines and Southern California. It excels at reflecting intense sun and shedding occasional rain. Surrey, British Columbia delivers the exact opposite: 1,400+ mm of annual rainfall spread across 169+ rainy days, winter humidity that rarely drops below 81%, and roughly 25 to 35 freeze thaw cycles every year as temperatures repeatedly cross zero between November and March.

Here is what happens underneath those tiles you cannot see. Concrete is porous. Each tile absorbs up to 13% of its weight in water during Surrey’s months of relentless rain. When that moisture freezes overnight, it expands roughly 9% inside the tile matrix. Spider cracks form. Each cycle widens them. After 15 to 20 years, tiles are often too brittle to walk on for basic repair work without causing more damage.

But the tiles are not the real failure point. The underlayment is. Traditional felt paper beneath concrete tile lasts only 12 to 20 years. Many Lower Mainland tile installations from the 1990s used organic cardboard underlayment or thin polyethylene sheeting that degrades even faster. The tiles may have a 50 year theoretical lifespan, but the waterproofing layer beneath them fails at the halfway mark. By the time you see a ceiling stain, water has been migrating through failed underlayment for months. We find this on essentially every tile roof assessment we conduct across Surrey.

The tiles survive. The system under them doesn’t. That’s what we find, project after project.

Columbia Roof Tiles and Unicrete Are Gone

This is the practical trigger forcing most Surrey homeowners into full conversion. The tiles they need no longer exist.

Columbia Roof Tiles was founded in the mid 1970s and based right here in Surrey. They manufactured extruded concrete tiles in four profiles — Double Roman, Northwest Shake, Northwest Slate, and Northwest Split Shake — each stamped “Columbia” on the reverse. Each tile weighed roughly 1,000 lbs per roofing square. Columbia ceased operations around 2015. Their tiles sit on thousands of Surrey roofs, but replacement stock was exhausted years ago.

Unicrete, based in Calgary, abruptly closed its factory in July 2014 after nearly 40 years. No concrete roof tile manufacturer currently operates in British Columbia or Western Canada. Other historical brands — Marley, Lifetime, Speo, Bar Tile — have similarly discontinued Canadian manufacturing. The nearest source is Eagle Roofing Products in the United States, but Eagle tiles are different profiles and colours from what is on existing Surrey roofs. They do not match.

Insurance claims for storm damaged tile roofs have become especially complicated. Adjusters sometimes declare no viable repair option exists. The reality is clear: repair and partial replacement are functionally impossible. Full conversion is the only path forward.

Why Plywood — and Never OSB — for Roof Decking in BC

When tile comes off, the deck beneath almost always needs replacement. Many tile roofs were installed over nothing more than underlayment draped across trusses with 1x4 cross straps nailed over top. No plywood sheathing at all. Even where sheathing exists, decades of moisture exposure under failing underlayment means rot, soft spots, and structural compromise.

We re deck with plywood. Always. The difference in BC’s wet climate is not marginal. It is categorical.

After multiple wet dry cycles, OSB swells up to 45% of its original thickness. Plywood swells just 7 to 9%. Once dried, plywood residual swelling drops under 6%. OSB never fully recovers. Worse, OSB suffers permanent irreversible edge swelling — when moisture reaches panel edges, the compressed wood strands release their manufacturing stress and expand forever. The panel never returns to its original dimension. This creates visible ridging under shingles that tears the roofing surface as it cycles through temperature and humidity changes.

After wet dry cycling, CDX plywood retains approximately 86% of its original strength. OSB retains only 63 to 70%. Plywood’s cross laminated construction provides inherent dimensional stability that OSB cannot match. Its nail holding ability remains superior when wet and it dries faster after exposure.

Our standard: half inch CDX plywood for rafters or trusses spaced at 16 inches on centre. For 24 inch spacing, 5/8 inch. Three eighths inch plywood is acceptable only as an overlay on existing solid board decks, never as primary structural sheathing. OSB costs 40 to 50% less per sheet. But plywood’s performance in BC’s climate makes the cost difference negligible across the life of the roof.

Five Replacement Options for Your Tile Roof

Once the tile is removed and the deck is properly re sheathed with plywood, you choose from five modern systems. Every option weighs dramatically less than the 900 to 1,100 lbs per square your concrete tile imposed for decades. That weight reduction alone removes enormous structural stress from your home’s framing.

Option 1 — Architectural Asphalt Shingles

The most popular tile conversion choice in Metro Vancouver. Architectural shingles from CertainTeed , Malarkey , and IKO weigh 175 to 350 lbs per square — roughly one quarter of concrete tile. They deliver 25 to 50 year warranties, Class A fire ratings, and dramatically better wind resistance than previous generation shingles. Malarkey Vista AR includes SBS modified rubber asphalt and algae resistance coating, both critical in Surrey’s wet climate.

Best for: Budget conscious conversions. Homeowners selling within 10 years. Maximum curb appeal per dollar spent. Conversion cost: $30,000–$55,000 total.

Option 2 — Standing Seam Metal Roofing

Metal roofing offers the longest service life at 40 to 70+ years. Standing seam panels shed Surrey’s heavy rain instantly, resist wind uplift exceeding 160 km/h, and support zero moss growth. Weight: 100 to 150 lbs per square. If you plan to stay long term, metal is the one and done solution.

Best for: Long term owners (20+ years). Zero maintenance preference. Lowest lifetime cost over 50 years. Conversion cost: $50,000–$80,000 total.

Option 3 — Enviroshake Synthetic Cedar Shake

Enviroshake is Canadian manufactured composite cedar shake from 95% post industrial recycled materials. Each tile is moulded from 3D scans of real cedar shakes. At roughly 260 lbs per square, it weighs about 75% less than concrete tile. Class A fire rating. Wind resistance rated to 290 km/h. Class 4 impact resistance. The Gold Level 50 year warranty is fully transferable.

For Surrey specifically: no moss, no mildew, no algae, no insects. Water runoff is potable. For homeowners converting from tile who want the cedar shake character that defines West Coast architecture, Enviroshake delivers it without the retreatment cycle real cedar demands in Surrey’s humidity.

Best for: West Coast cedar aesthetic. Eco conscious homeowners. 50 year performance with zero organic maintenance. Conversion cost: $30,000–$50,000 total.

Option 4 — Brava Composite Tile

For homeowners wanting to maintain a tile aesthetic, Brava Roof Tile offers composite profiles replicating slate, cedar shake, and Spanish barrel vault. Made from 100% recycled polyethylene with UV resistant mineral pigments infused through the full thickness — colour cannot wear off. Old World Slate: 1 inch butt thickness, the thickest synthetic slate available. Spanish Barrel Vault: just 281 lbs per square — 70% lighter than concrete barrel tile. All profiles: Class 4 impact, wind to 340 km/h with screws, 50 year warranty.

Best for: Preserving tile roofline character. Panorama Ridge and South Surrey custom homes. Conversion cost: $35,000–$65,000 total.

Option 5 — Euroshield Recycled Rubber Roofing

Euroshield is manufactured in Calgary from approximately 70% recycled tire rubber. Each roof diverts 250 to 1,000+ tires from landfill. Standard Beaumont Shake: 210 lbs per square. All profiles: Class 4 impact. Vermont Slate HP: warranted hail proof against any size hailstone for 20 years. Standard 50 year warranty. Rubber naturally repels moisture and handles freeze thaw without degradation. Superior sound dampening during heavy rain — a genuine benefit when it rains 169+ days per year.

Limitation: Class C fire rating, lower than Enviroshake and Brava’s Class A.

Best for: Maximum impact resistance. Environmental sustainability. Conversion cost: $35,000–$60,000 total.

Surrey Neighbourhoods With the Most Tile Roofs

Concrete tile is concentrated in Surrey neighbourhoods that experienced their primary building boom between 1985 and 2005 — the era when Columbia Roof Tiles was at peak production.

Real Tile Conversion Costs in Surrey for 2026

Tile conversion costs more than a standard re roof because of the heavy tear off, disposal logistics, and near certain need for full re decking. For a typical 2,500 sq ft roof in Surrey:

Tile tear off:$7,500–$12,500 (2–3x standard asphalt removal due to weight). Disposal:$2,000–$3,500 for 2–4 dumpster loads at ~$595 each. Full plywood re decking:$5,500–$8,000 (~78 sheets of half inch CDX plywood installed).

Financing available. The lifecycle math is compelling: one Enviroshake or Brava at $40K outlasts two asphalt cycles costing $60K+ combined over the same 50 year window.

The Tile Conversion Process Step by Step

Post Conversion Maintenance by Material

One of the biggest advantages of converting from tile is dramatically reduced maintenance.

Asphalt shingles: Annual inspection , moss treatment every 12 to 18 months, gutter cleaning twice yearly. Still far less than tile which required all of this plus periodic underlayment replacement.

Metal roofing: Annual visual inspection. Gutter cleaning. Occasional rinse. That is it. The lowest maintenance option available.

Enviroshake: Annual inspection. Composite surface resists moss and algae naturally. No retreatment cycles unlike real cedar. Essentially maintenance free beyond keeping gutters clear.

Brava composite: Annual inspection. Mineral infused colour does not fade. Non porous surface means no moss penetration. Maintenance free beyond gutter clearing.

Euroshield rubber: Annual inspection. Rubber repels moisture and organisms. Flexible material handles temperature cycling without cracking. Minimal ongoing attention required.

Which Replacement Is Right for Your Surrey Home

Four questions cut through everything else. How long are you staying? Under ten years: asphalt. Over twenty: run the lifetime cost comparison — metal nearly always wins. Does the roofline character matter? If your home is defined by its tile profile, Brava’s Barrel Vault preserves it at 70% less weight. A flat shingle on a tile designed home reads as a downgrade. Composite does not. Do you want the cedar shake West Coast look? Enviroshake delivers it with a 50 year warranty and zero retreatment. Is environmental impact a priority? Euroshield diverts 250–1,000 tires from landfill per roof.

Contractor selection matters more than material selection. The best shingle fails in fifteen years if the underlayment is wrong, the ventilation is inadequate, or the flashings are poorly detailed. Before signing any contract, ask for manufacturer certifications, references from completed tile conversion projects specifically, and read the workmanship warranty in full.
