If you’re looking for a roofing system that delivers durability, strong UV resistance, and superior energy efficiency for your flat or low-slope roof, TPO (Thermoplastic Polyolefin) roofing is one of the best choices available. Many homeowners and commercial property owners in Surrey, BC prefer TPO because it significantly reduces cooling costs, handles BC’s unpredictable weather, and provides a long-lasting waterproof seal.
At I-M Roofing Ltd, we specialize in professional TPO roofing installation, replacement, and repair—helping you protect your building with a roofing system that performs exceptionally well for decades.
TPO roofing is one of the top choices for Surrey property owners because of its advanced waterproofing and durability. Here’s what makes it stand out:
TPO’s bright white surface reflects UV rays, keeping your building cooler during the summer and reducing energy bills significantly.
The heat-welded seams create a watertight barrier, preventing leaks even during heavy rainfall—a major advantage for Surrey’s rainy climate.
TPO membranes resist tears, punctures, and chemical exposure, making them ideal for both residential and commercial buildings.
TPO adapts well to structural movement and temperature changes without cracking or shrinking.
At I-M Roofing Ltd, we follow a proven, detail-oriented process to ensure your TPO roofing system performs at its best.
We begin by evaluating your roof’s structure, drainage, insulation, and existing materials to determine the best TPO solution.
Proper preparation ensures long-lasting results. We clean the roof deck, repair damaged areas, and install insulation if needed.
We roll out the TPO membrane and secure it using industry-standard techniques for maximum durability.
We use advanced hot-air welding tools to seal seams tightly, preventing leaks and improving structural integrity.

TPO stands for Thermoplastic Polyolefin. It is a single-ply roofing membrane made from polypropylene and ethylene-propylene rubber.
TPO is a white reflective membrane that is heat-welded at the seams. The heat-welded seams create a watertight bond that is stronger than the membrane itself.
TPO comes in three thicknesses:
45-mil: Standard residential and light commercial
60-mil: Commercial, high-traffic areas
80-mil: Industrial, heavy-duty applications
For most Surrey flat roofs, 60-mil TPO is the best choice. It balances durability and cost.
TPO is available in several colors:
White (most common, best energy reflectivity)
Grey
Tan
White TPO is the most popular for energy savings. It reflects sunlight, keeping buildings cooler and reducing cooling costs.
Three main systems are used on flat roofs in Surrey. Here is how they compare.
| Factor | TPO | EPDM | Torch-On |
|---|---|---|---|
| Material | Thermoplastic polyolefin | Rubber | Modified bitumen |
| Lifespan in Surrey | 20-30 years | 20-30 years | 20-25 years |
| Cost per square | $400 to $700 | $350 to $600 | $450 to $750 |
| Installation | Heat-welded seams | Glued or mechanically fastened | Torch-applied (heat) |
| Energy efficiency | Excellent (white reflects UV) | Poor (dark absorbs heat) | Moderate |
| Cooling cost savings | 10-20% reduction | 0-5% reduction | 5-10% reduction |
| Appearance | Clean, modern | Black, utilitarian | Granulated or smooth |
| Repairs | Requires heat welding | Rubber patch | Torch-on patch |
| Ponding water | Good | Excellent | Excellent |
| Foot traffic | Moderate | Moderate | Excellent |
| Best for | Energy-conscious owners, commercial buildings | Budget-conscious projects, complex roofs | High-traffic roofs, strata buildings |
When to choose TPO:
You want to reduce energy costs
Your roof is visible and appearance matters
You want a modern, proven system
You are a commercial building owner looking for LEED points
When to choose EPDM:
You are on a tight budget
Your roof has complex details and penetrations
Ponding water is a concern (EPDM handles it well)
When to choose Torch-On:
Your roof has high foot traffic (HVAC, maintenance)
You want the most durable system
You have an existing torch-on roof and want to match

TPO is a “cool roof” membrane. It reflects sunlight instead of absorbing it.
| Feature | White TPO | Dark EPDM | Asphalt Shingles |
|---|---|---|---|
| Solar reflectivity | 80-85% | 10-15% | 10-20% |
| Surface temperature (sunny day) | 120-130°F | 170-190°F | 150-170°F |
| Cooling cost reduction | 10-20% | 0-5% | 0-5% |
| Building comfort | Much cooler | Hotter | Moderate |
How TPO saves money:
Reflects sunlight: White TPO reflects 80-85% of UV rays
Less heat enters the building: Lower cooling costs
Reduced HVAC wear: System runs less, lasts longer
Lower carbon footprint: Less energy consumption
Estimated annual cooling savings in Surrey:
1,500 sq ft flat roof: $200-$400 per year
2,000 sq ft flat roof: $300-$600 per year
5,000 sq ft commercial: $800-$1,500 per year
Over 20 years, a TPO roof can pay for itself in energy savings alone.
TPO can reduce your cooling costs by 10-20%. Call 236-838-9577 for a quote and see the savings.
TPO roofing costs $400 to $700 per square (100 sq ft) for most Surrey flat roofs.
| Roof Area | 45-mil TPO | 60-mil TPO | 80-mil TPO |
|---|---|---|---|
| 1,000 sq ft (small flat roof) | $4,000 to $5,500 | $4,500 to $6,500 | $5,500 to $7,500 |
| 1,500 sq ft (addition or townhouse) | $6,000 to $8,250 | $6,750 to $9,750 | $8,250 to $11,250 |
| 2,000 sq ft (garage or workshop) | $8,000 to $11,000 | $9,000 to $13,000 | $11,000 to $15,000 |
| 5,000 sq ft (commercial) | $20,000 to $27,500 | $22,500 to $32,500 | $27,500 to $37,500 |
What affects the price:
Thickness (45-mil vs 60-mil vs 80-mil)
Installation method (mechanically fastened vs fully adhered vs ballasted)
Existing roof removal ($1,500-$4,000)
Insulation replacement ($500-$2,000)
Roof complexity (curbs, vents, drains, parapet walls)
Building height (scaffolding costs)
Installation methods:
Mechanically fastened: Fasteners secure membrane to deck. Lower cost.
Fully adhered: Membrane glued to insulation. Higher cost, better wind resistance.
Ballasted: Membrane held down with gravel or pavers. Lowest cost, heavier.
Every roof is different. Call 236-838-9577 for a quote specific to your flat roof.
TPO roofs last 20 to 30 years in Surrey’s climate with proper installation and maintenance.
| Factor | Impact on TPO Roof |
|---|---|
| Heavy rain (1,200-1,600mm/year) | TPO sheds water well. Proper slope and drains are critical. |
| Ponding water | TPO handles standing water. Ensure drains are clear. |
| Freeze-thaw cycles (40-60 per year) | TPO is flexible. Expands and contracts with temperature. |
| UV exposure | White TPO reflects UV. No degradation. |
| Heat welding | Seams are stronger than membrane. |
What eventually fails on a TPO roof:
Seams (if not properly heat-welded)
Flashings (around curbs, vents, parapet walls)
Punctures (from foot traffic or debris)
Shrinkage (membrane can shrink over time)
With proper maintenance, a TPO roof can last 25+ years in Surrey.

1. What is TPO roofing?
TPO (Thermoplastic Polyolefin) is a single-ply roofing membrane used on flat and low-slope roofs. It is heat-welded at the seams for a watertight seal and reflects sunlight to reduce cooling costs.
2. How long does a TPO roof last in Surrey?
20 to 30 years with proper installation and maintenance. 60-mil and 80-mil membranes last longer than 45-mil.
3. Is TPO better than EPDM for flat roofs?
TPO is better for energy efficiency (white reflectivity) and appearance. EPDM is better for affordability and flexibility. The best choice depends on your priorities.
4. How much does TPO roofing cost in Surrey?
$400 to $700 per square (100 sq ft). 45-mil is the most affordable. 60-mil and 80-mil cost more but last longer.
5. Can TPO be installed over existing roofing?
Yes, in some cases. TPO can be installed over one layer of existing roofing if the deck is solid. However, we recommend tear-off for proper inspection and insulation.
6. Does TPO come with a warranty?
Yes. 20-30 year manufacturer warranty on the membrane. 10-year workmanship warranty from Imroofs.
