TPO vs. EPDM: What’s Best for Your Commercial Roof?

TPO Roofing in Calgary provides a robust, energy-saving option for commercial and residential flat roofs. Renowned for its heat-reflective properties and weather resistance, TPO (Thermoplastic Olefin) is perfect for Calgary’s ever-changing climate.

Its lightweight and cost-effectiveness have made it a favorite among property owners looking for durable performance with minimum upkeep. At Superior Roofing Ltd., our TPO installation specialists deliver quality solutions customized to Calgary’s specific demands, offering dependable coverage through all seasons.

If you’re trying to choose between TPO vs. EPDM roofing in Calgary, it’s important to evaluate their merits against each other in the context of our city’s unpredictable weather. Both are common for use on flat and low-slope roofs, but their distinctions can impact durability and appropriateness.

TPO is fantastic from an energy efficiency standpoint. Its white reflective surface helps the roof absorb less heat, keeping buildings cooler in summer. It is this feature that makes TPO so great for energy-conscious property owners who want to cut down on cooling costs.

Instead, EPDM’s black surface attracts heat, which makes it ideally suited for cold climates where absorbing warmth is beneficial. Although both materials tend to have a similar lifespan of 25-30 years with proper maintenance, TPO is often backed by warranties that last up to 30 years, which showcases manufacturers’ confidence in its durability.

Cost-wise, EPDM typically costs less, with an average price of around $4-$6 per square foot. TPO pricing can fluctuate but ends up in roughly the same place depending on install difficulty. TPO’s energy-saving properties could compensate for its initial expense, particularly in Calgary’s bright summer months.

On the environmental front, TPO wins thanks to its recyclability. Most TPO membranes are recyclable after their life, which minimizes waste. EPDM, though long-lasting, isn’t quite as green.

Both materials’ performance is highly reliant on the type of insulation installed beneath them and how this affects thermal efficiency and overall durability.

Both TPO and EPDM have different strengths, so the decision is very much property-dependent. TPO wins on energy efficiency and environmental impact, whereas EPDM performs well in lower temperatures and budget projects.

Speaking to a roofing specialist is key to guaranteeing the best fit for Calgary’s climate.

TPO roofing has rapidly emerged as a popular option for Calgary property owners thanks to its durability, affordability and green features. This versatile single-ply membrane provides durable, energy-efficient protection tailored to fit different building requirements and climates.

TPO roofing is known for its heat-reflective properties. Its white reflective surface reflects sunlight, decreasing heat absorption and internal cooling costs during Calgary’s warmer months. With a high Solar Reflective Index rating—sometimes hitting 97%—it’s a great choice for energy-conscious property owners seeking to trim their utility bills.

These energy savings add up over time, making TPO a shrewd investment. Another huge benefit is TPO’s resistance to UV rays, ozone and chemical exposure. Calgary’s changing seasons, from brutal winters to sunny summers, can be hard on many roofs.

TPO’s makeup enables it to weather such conditions, resisting harm from extended sun exposure, temperature changes, or industrial pollutants. This durability is echoed by its average lifespan of 20 to 30 years, offering decades of protection for your home.

Affordability is another key aspect. TPO is competitively priced against other single-ply systems such as PVC. Even though it’s more affordable, it doesn’t skimp on quality or durability, so it’s a sensible option for residential and commercial use.

TPO’s seamless, flexible design makes it ideal for flat and low-sloped roofs of any size. For eco-conscious users, TPO is 100% recyclable, minimizing landfill impact and facilitating green construction. With TPO, you don’t just get a trusted roofing system, you make a sustainable choice.

Certified TPO installation best practices maximize the performance—and lifespan—of TPO roofing systems, which can last 20 to 30 years when installed properly. Designed for durability, energy efficiency, and Calgary’s weather, you want to install your TPO using best practices.

Substrate prep is the cornerstone of a fluid TPO installation. Clean, dry and free of debris or sharp objects that could puncture the membrane. Any anomalies like cracks or uneven areas should be repaired before the membrane is applied. A properly prepared substrate doesn’t just make for good adhesion, it stops problems down the road such as leaks or materials failure.

Seasoned TPO contractors are a necessity. TPO membranes use heat-welded seams to form a waterproof connection. This is a craft that must be done carefully to prevent vulnerable spots on the roof. Contractors accustomed to ASTM D6878 can guarantee the membrane satisfies key criteria like tearing strength and weather resistance — essential for Calgary’s diverse weather.

Subsidiary to this, proper drainage must be employed to avoid water pooling on flat roofs. According to the International Building Code, a minimum slope of ¼:12 is required for effective water runoff. When your roof doesn’t drain properly it can cause structural damage or enhanced wear and tear, especially in snow and ice zones.

Key best practices for TPO installation include:

• Choosing the right membrane thickness based on project needs (45-mil or 60-mil).
• Backed by Uni-Force reinforced scrim, we manufacture using rolls sized for efficient coverage — 1.9 m x 30.5 m (6′5″ x 100′).
• Having routine inspections to catch any damages from snow or debris.
• Building for energy efficiency by taking advantage of TPO’s reflective properties, which helps to cut cooling costs.

TPO roof maintenance is crucial to extend the life of the roof and to make sure it performs as expected in Calgary’s tough climate. With routine maintenance, along with proper installation and preventative care, a TPO roof can stay in tip-top shape for 20 to 30 years. Inspections, cleaning, and timely repairs are key to keeping small problems from turning into expensive ones.

You should conduct a thorough inspection of your TPO roof once or twice a year to catch any signs of damage before they escalate. A trained roof technician can identify issues like punctures, seam separation or UV degradation before it results in leaks or structural problems. Inspections are particularly critical after severe weather events such as hail storms that can pock the TPO membrane.

Sharp debris, foot traffic or falling branches are other common causes of wear, making professional evaluations crucial. Periodic cleaning of your TPO surface is another key step. Dirt and debris and pollutants can build up, diminishing the roof’s reflective qualities and energy efficiency.

TPO roof maintenance is minimal, and using a soft-bristle brush and mild cleaning solution can help maintain its white surface, which reflects sunlight and reduces cooling costs. Stay away from harsh chemicals, they could wreck the membrane.

That’s why sealing seams or repairing punctures immediately is essential to stop leaks. TPO membranes are very resilient. Locations around seams or fasteners might be prone. They provide prompt repairs that keep your roof watertight and intact.

• Have it inspected each year or every other year by a trained professional
• Clear of debris and clean periodically to preserve reflectivity.
• Use walk pads to control foot traffic and prevent damage.
• Repair seams or punctures immediately to prevent water infiltration.
• Limit roof access to essential personnel to reduce wear.

TPO roofing in Calgary has been gaining popularity due to its durability, energy efficiency, and sustainability benefits. Knowing its broader value can assist homeowners in making highly educated choices.

TPO roofing can play an important part in LEED certification for green buildings. Its reflective surface, frequently laid in luminous white, reflects UV rays, reducing heat absorption. This not only helps reduce the urban heat island effect but also reduces cooling requirements during Calgary’s hot summers.

For flat and low-slope roofs, TPO’s energy-saving qualities translate into significant ecological and economic savings.

• 100% recyclable materials, reducing landfill waste.
• Superior UV resistance, decreasing energy costs for cooling.
• Compatibility with solar panel installations due to reflective surfaces.
• Lightweight design, reducing structural stress on buildings.
• Durable, if well taken care of, helps you to be more long-term sustainable.

Long-term cost-savings are another huge benefit of TPO roofing. Lower energy bills, due to its reflective qualities, and low maintenance make it a cost-efficient answer.

With maintenance and inspections designed to catch damage early, TPO roofs can extend to 30 years or more, providing fantastic value for your buck.

There’s some myths about TPO, especially around its lifespan. Although others think it’s less durable, installation and maintenance are key.

TPO membranes are available in multiple widths, which makes it easy to choose the correct size for your roof. For roofs with under 25% saturated insulation, silicone restoration systems can buy more life instead of complete replacement.

Navigating local building codes is important in Calgary for TPO roofing. These codes are important for safety, durability, and city compliance. They can be tricky and time-consuming to navigate. Missing these could result in fines or delays, so strategic planning is important.

Ensuring that TPO complies with Calgary’s codes should be priority one. TPO roofing has to comply with local building codes regarding energy efficiency, durability, and environmental impact. Take, for example, Calgary’s climate, with its temperature fluctuations and bouts of extreme weather, which requires materials that can endure these elements.

Make sure whatever TPO product you select complies with these before you start your project. Insulation and fire resistance are other concerns. We had to navigate Calgary’s local building codes, which require minimum R-values for insulation — a vital consideration for flat-roofed buildings.

Fire resistance ratings are just as key, particularly for commercial properties, to provide safety and meet local fire codes. Checking your city’s regulations or consulting with an experienced roofing contractor can streamline this process.

Securing permits is important. In Calgary, roofing projects require permits, and the process typically involves at least two inspections: one mid-project and another upon completion. In many areas, residential permits can be approved in 3-14 business days depending on their complexity and commercial permits in up to four weeks.

If you don’t obtain the right permits, you could be fined hundreds or thousands of dollars. Below is a summary of key TPO roofing requirements in Calgary:

TPO roofing provides durability, energy savings, and rock-solid performance for Calgary’s unique weather. It’s a savvy option for flat roofs, no matter if you’re retrofitting a commercial building or bidding on a new one. Properly installed and maintained, TPO can take on brutal winters and sizzling summers while keeping energy bills low.
