Flat Roof Replacement Built for New England Weather
Flat roofs in Southern NH and Maine face unique challenges, including:
- Heavy snow accumulation and ice buildup
- Freeze-thaw cycles that stress seams and membranes
- Ponding water from improper drainage
- High winds and driving rain
- UV exposure during summer months
A proper flat roof replacement isn’t just about new material — it’s about correct system design, insulation, slope management, and quality installation. Tall Pine Roofing focuses on complete flat roofing systems that perform year-round.
Flat Roofing Systems We Install
We install proven flat roofing systems known for performance, flexibility, and durability in New England climates.

EPDM Rubber Roofing
EPDM (ethylene propylene diene monomer) is one of the most reliable flat roofing materials available. This rubber roofing system offers:
- Excellent resistance to temperature extremes
- Strong flexibility during freeze-thaw cycles
- Proven long-term performance
- Cost-effective replacement solutions
EPDM is a popular choice for commercial buildings and condos throughout NH and ME due to its durability and repairability.

TPO Roofing Systems
TPO (thermoplastic polyolefin) is a heat-welded membrane that provides strong seam integrity and energy efficiency. Benefits include:
- Reflective surface to reduce cooling costs
- Strong resistance to UV exposure
- Clean, modern appearance
- Excellent performance on low-slope roofs
TPO is a great option for property owners looking to improve energy efficiency while maintaining long-term protection.
Modified Bitumen Roofing
Modified bitumen is a reinforced asphalt-based roofing system designed for durability and foot traffic resistance. It’s well-suited for buildings that require added toughness and layered protection.
When to Consider a Flat Roof Replacement
You may need a flat roof replacement if you’re experiencing:
- Persistent or recurring leaks
- Cracked, blistered, or deteriorating membrane
- Wet insulation or interior water damage
- Pooling water that doesn’t drain properly
- A roof that has exceeded its service life
Our team performs detailed inspections to determine whether a full replacement is the most cost-effective solution or if repairs are still viable.
