What Is TPO Roofing?
TPO (Thermoplastic Polyolefin) roofing is a single-ply membrane commonly used on commercial buildings and flat residential rooftops. Its popularity has grown in recent years because it offers reliable performance, budget-friendly pricing, and energy-saving benefits.
TPO reflects sunlight, helping reduce cooling costs during the warmer months. It also offers impressive resistance to punctures and physical damage, as well as UV rays and chemical exposure.
TPO vs. EPDM vs. PVC: Which Is Best For You?
When selecting a flat roofing system, it’s important to compare your material options based on a variety of factors, such as performance, durability, climate compatibility, and cost. When selecting a flat roofing material, it’s essential to consider the ups and downsides of each option.
Here’s a closer look at the three most commonly used flat roofing materials, TPO, EPDM, and PVC, and what makes each one unique.
TPO (Thermoplastic Polyolefin)
TPO is one of the fastest-growing choices for roofing materials for commercial and residential flat roofs. It’s a single-ply membrane known for its white, highly reflective surface, which helps reduce energy costs by deflecting sunlight and keeping the interior cooler.
Pros
- Optimized Energy Use: A highly reflective surface reduces cooling costs in warmer months.
- Heat-Welded Seams: TPO’s welded seams offer superior waterproofing compared to adhesives.
- Affordable: Less expensive than PVC while still offering excellent durability.
- Mold & Dirt Resistance: The membrane naturally resists buildup from grime, mildew, and debris.
- Flexible Application: Works well on both commercial and residential buildings.
Cons
- UV Breakdown Over Time: Lower-quality TPO membranes may degrade more rapidly under intense sunlight exposure.
- Newer Material: While it’s gaining popularity, TPO is still a relatively new material, meaning it doesn’t have as long a track record as EPDM.
- Inconsistent Manufacturing: Quality can vary significantly between brands.
EPDM (Ethylene Propylene Diene Monomer)
EPDM is an artificial rubber membrane that has been widely used for flat roofs for over 5 decades. It is especially known for its flexibility and weather tolerance, making it a strong choice in colder climates.
Pros
- Proven Longevity: Has a long track record of 20–30+ years of dependable use.
- Weather Resistant: Performs well in extreme cold and fluctuating temperatures.
- Flexible: Ideal for roofs with curves or unusual shapes.
- Cost-Effective: Often the most budget-friendly flat roofing material.
- Low Maintenance: Requires minimal upkeep once installed.
Cons
- Less Reflective: Black surface absorbs heat, which can raise cooling costs in warm climates.
- Seam Adhesion: Uses adhesives instead of heat welding, which may be less watertight over time.
- Appearance: Not as visually sleek or modern-looking as TPO or PVC.
PVC (Polyvinyl Chloride)
PVC is a durable and chemically resistant roofing membrane often used in commercial settings. It is similar in application to TPO but with added benefits that make it ideal for roofs with higher environmental demands.
Pros
- Superior Chemical Resistance: Perfect for roofs with exhaust vents or grease-producing equipment.
- Heat-Welded Seams: Like TPO, it features heat-welded seams for a watertight bond.
- Fire Retardant: PVC membranes are naturally flame-resistant.
- Long Lifespan: Can last 20–30+ years with proper installation and maintenance.
- UV and Puncture Resistance: Strong against both sun damage and physical wear.
Cons
- Higher Cost: More expensive than TPO and EPDM, both in materials and installation.
- Less Flexible in Cold Weather: Can become brittle in extremely cold climates if not properly formulated.
- Environmental Concerns: Contains plasticizers and other additives that may not appeal to eco-conscious buyers.
Common Flat Roofing Issues and How We Repair Them
Flat roofs are prone to certain issues over time, especially if they were improperly installed or neglected.
Some of the most common problems we see include:
- Ponding Water: Water that doesn’t drain properly can break down materials and lead to leaks.
- Membrane Cracks or Punctures: Foot traffic, weather, or debris can damage the surface.
- Loose Flashing: Poorly sealed edges or corners can allow moisture to enter.
- Shrinkage: Some materials may shrink over time, pulling away from edges and seams.
Our repair approach depends on the issue, but always starts with a detailed inspection. From there, we might patch damaged areas, replace flashing, improve drainage, or re-seal seams. Thanks to our decades of experience, we’re equipped to handle even complex repairs without compromising the integrity of your roof.
