Overview of Commercial Flat Roof Types
Commercial flat roofs are usually built with a slight slope for water drainage, but their low-profile nature can make them prone to specific challenges. Various materials are designed to address these challenges, among them are:
- Thermoplastic Polyolefin (TPO)
- Polyvinyl Chloride (PVC)
- Ethylene Propylene Diene Monomer (EPDM)
- Modified Bitumen
- Built-Up Roofing (BUR)
In-Depth Review of the Best Roofing Materials
TPO
TPO is one of the most popular roofing materials for commercial flat roofs, especially for buildings in areas with intense sunlight. Its heat-welded seams make it super strong and durable. Plus, it’s highly reflective, making it an energy-efficient choice that helps lower cooling costs.
Benefits:
- Reduces heating and cooling costs due to high reflectivity.
- Has excellent resistance to UV rays, chemicals, and punctures.
- More affordable than some alternatives, but still offers strong performance.
Drawbacks:
- Installation can be tricky if not done by professionals, as it can shrink or become brittle over time.
PVC
PVC is made from strong, flexible vinyl material—famous for its durability and resistance to UV exposure. This material is often used in areas with high chemical exposure or extreme temperatures as it is resistant to cracking and tearing.
Benefits:
- Highly resistant to UV damage, chemicals, and extreme weather conditions.
- Easy to maintain and clean.
- Has a long lifespan and is energy-efficient.
Drawbacks:
- More expensive than TPO.
- Installation may need skilled labor to ensure proper welding of seams.
EPDM
EPDM—commonly known as rubber roofing—is one of the most cost-effective options for commercial flat roofs. It has a long lifespan, and is resistant to ozone, UV radiation, and weathering.
Benefits:
- One of the most budget-friendly roofing materials for flat roofs.
- Withstands harsh weather, making it a good choice for regions with extreme temperature swings.
- Small tears or punctures can be repaired without much hassle.
Drawbacks:
- Less energy-efficient compared to TPO and PVC.
- Prone to damage from pooling water if the roof is not properly maintained.
Modified Bitumen
Modified bitumen is an asphalt-based roofing material reinforced with modifiers to boost its flexibility and durability. It’s often used in areas with fluctuating temperatures and heavy foot traffic.
Benefits:
- Best for climates with extreme temperature swings.
- Can be installed in rolls, which reduces labor costs.
- Great for buildings with a high volume of foot traffic.
Drawbacks:
- Needs more maintenance than TPO or PVC.
- May not be as energy-efficient.
BUR
BUR roofs are made from multiple layers of bitumen and reinforcing fabrics. They’re usually topped with gravel, durable, and great at keeping water out.
Benefits:
- Long-lasting with excellent weather resistance.
- Multiple layers offer superior waterproofing.
- Great for buildings with high drainage concerns.
Drawbacks:
- Can be very weighty and may need extra structural support.
- Higher initial cost and more complex installation.
How Weather & Climate Affect Your Roof Choice
When choosing a roofing material for a commercial flat roof, factor in the local climate and weather patterns. For example, in areas with harsh winters and rapid snowmelt, TPO and EPDM are excellent choices due to their weather resistance and durability. PVC is great for places with high UV exposure, as it’s highly resistant to UV degradation.
In regions with frequent storms, Modified Bitumen or BUR may be ideal due to their superior resistance to wind and moisture. Additionally, roofing materials with reflective surfaces—like TPO—can help cut down on the cooling load in buildings in hot climates, saving on energy costs.
Common Mistakes to Avoid When Choosing Roofing Materials
- Choosing Based on Price Alone: While cost is always a factor, it’s also important to think about the long-term durability and energy efficiency of the roofing material.
- Not Considering Local Climate: Failing to choose materials suited to your region’s weather can result in premature damage and higher maintenance costs.
- Neglecting Professional Installation: Even the best materials can fail if not installed correctly. Always hire a certified roofing contractor for installation.
- Ignoring Long-Term Maintenance: Some roofing systems, like Modified Bitumen or BUR, need more regular maintenance. Make sure you’re prepared for the upkeep of the material you choose.
