Flat Roof Options for Missouri Homes and Commercial Buildings
Flat and low-slope roofs are common on commercial buildings, multi-family properties, and certain modern-style homes in the St. Louis area. Choosing the right flat roofing system is critical for preventing leaks and keeping your building protected.
Perfect Pitch Roofing & Exteriors installs and repairs flat roofs throughout Eureka and the surrounding counties, including TPO and other commercial-grade systems.
Common Flat Roofing Systems We Use
- TPO (Thermoplastic Polyolefin)
- Single-ply membrane, typically white or light-colored
- Highly reflective and energy-efficient
- Heat-welded seams for strong, watertight connections
- Popular choice for commercial buildings and some residential flat roofs
- Modified Bitumen
- Asphalt-based system with added polymers for flexibility
- Installed in rolls; can be torched, cold-applied, or self-adhered
- Good option for smaller flat roofs and certain residential applications
- EPDM (Ethylene Propylene Diene Monomer)
- Synthetic rubber membrane, usually black
- Durable and flexible, especially in cold temperatures
- Common on older commercial roofs; still used today in some applications
How We Recommend the Right Flat Roof System
We look at:
- Building type and use – Residential vs. commercial, foot traffic, rooftop equipment
- Roof size and layout – Drains, penetrations, and existing structure
- Budget and long-term plans – How long you plan to own or occupy the building
- Energy efficiency goals – Reflective TPO can help reduce cooling costs
We’ll walk you through the pros and cons of each system and explain our recommendation in straightforward terms.
Flat Roof Maintenance Tips
Flat roofs require regular maintenance to perform their best:
- Keep drains and scuppers clear of leaves and debris
- Schedule routine inspections to catch seam issues, punctures, or ponding water
- Address minor problems early to avoid leaks and interior damage
