Flat Roofs in Maryland: Lifespan & Maintenance
Flat roofs are actually very common in Maryland, especially on rowhomes in Baltimore, commercial buildings, and modern-style homes. Here’s how long flat roofing systems typically last and what impacts their lifespan in Maryland’s climate:
EPDM (Rubber Membrane)
Lifespan: ~15–25 years
Pros: Cost-effective, flexible in cold weather, easy to repair
Cons: Vulnerable to punctures, can shrink over time
Tip: Re-seal seams and edges every 5–10 years for best performance
TPO (Thermoplastic Polyolefin)
Lifespan: ~20–30 years
Pros: Energy efficient (white reflective surface), resistant to algae and UV
Cons: Can be less flexible in cold snaps if poorly installed
Tip: Great for flat roofs on commercial or modern residential homes
Modified Bitumen (ModBit)
Lifespan: ~20 years
Pros: Durable, layered, and excellent at handling foot traffic
Cons: May absorb more heat if using darker surfacing
Tip: Add a reflective coating to reduce UV wear and extend life
Built-Up Roofing (BUR)
Lifespan: ~20–30 years
Pros: Very tough, multiple layers of felt/asphalt and gravel
Cons: Heavier system, slower to install, older tech
Tip: Best suited for large commercial buildings or historic restorations
🌦️ Maryland-Specific Concerns for Flat Roofs
To get the most life out of your flat roof:
✅ Inspect annually and after big storms or heavy snow
✅ Keep drains and scuppers 100% clear
✅ Patch punctures ASAP — even small ones can leak
✅ Consider a white or reflective coating to reduce heat damage
🛠️ Flat Roof Maintenance Tips
Flat roofs in MD face some unique challenges:
