Flat Roofing Materials
flat roofing contractors systems are durable and low maintenance. But the material used can make a big difference on the performance and lifespan of the roof. Here are the main options:
EPDM (Ethylene Propylene Diene Monomer)
EPDM is a synthetic rubber roofing membrane that has been around in the flat roofing industry for years. It’s popular for its durability and weather resistance.
EPDM:
Advantages:
· Longevity: up to 50 years with maintenance.
· Flexibility: stays flexible in freezing temperatures, good for all climates.
· Ease of Installation: lightweight and easy to install, reduces labor cost.
Disadvantages:
· Appearance: EPDM comes in black or dark grey; not all looks are good.
· Seam Issues: although seam technology has improved, seams are still a weak point.
TPO
TPO roofing is a newer option that combines the durability of rubber with the heat reflective properties of a thermoplastic. It’s designed to be energy efficient.
TPO advantages:
· Energy Efficiency: TPO membranes are reflective and reduce cooling costs by reflecting UV rays.
· Resistance: good puncture, tear, and impact resistance.
· Cost Effective: TPO is cheaper than other roofing options while still performing well.
Disadvantages:
· Heat Aging: TPO can become brittle over time due to heat exposure and may crack.
· Limited Track Record: as a newer material it doesn’t have the long term performance history of EPDM.
PVC (Polyvinyl Chloride)
PVC roofing is a single-ply membrane that’s known for its chemical and environmental resistance. It’s commonly used for commercial applications.
PVC advantages:
· Durability: PVC is resistant to chemicals, fire, and water and is good for roofs with harsh exposure.
· Reflectivity: like TPO, PVC membranes are reflective, which reduces energy costs.
· Seam Strength: Heat-welded seams in PVC roofing are strong and waterproof.
Disadvantages:
· Cost: PVC is more expensive than EPDM and TPO.
· Installation: requires specialized skills, adds to the overall cost.
Modified Bitumen
Modified bitumen is an asphalt-based roofing material that has been modified to improve its performance. It’s used in areas where high environmental resistance is required.
Pros of Modified Bitumen:
· Strength: Modified bitumen is durable and resistant to UV and physical damage.
· Flexibility: It stays flexible in cold temperatures to prevent cracking.
· Easy Maintenance: Modified bitumen roofs are easy to repair and maintain.
Cons:
· Installation: Installation is complex and requires professional expertise.
· Aesthetic Limitations: Modified bitumen may not look as modern as other options.
Basement Waterproofing and Flat Roofing: An Integrated Approach
When you’re thinking of flat roofing, you should also think of basement waterproofing. A flat roof can lead to water accumulation if not managed properly which can affect the basement and the overall building. Materials like EPDM and PVC are great for both roofing and waterproofing because of their water resistance and durability.
