low slope roofing

Not every roof is built with the same pitch and that matters more than most homeowners realize.

Low slope roofing is designed for areas of your home where water doesn’t drain as quickly, like porches, additions, garages, and flat roof sections. These areas require specialized materials that are built for waterproofing, not just water shedding.

What is Low Slope Roofing?

  • Low slope roofing systems

    A low-slope roof typically has a pitch of 3:12 or less; it requires a different system than standard shingles to prevent leaks.

  • Built for waterproofing, not just shedding water

    Low slope roofing materials create a continuous barrier to protect against leaks, especially important in New Hampshire’s snow and ice conditions.

  • Common in Dover NH homes & additions

    You’ll often find low slope roofing on porches, dormers, garages, and home additions throughout the Seacoast area.

  • Specialized materials required

    Unlike standard roofing systems, low slope roofing uses membranes and rolled materials designed specifically for these conditions.

Low Slope Roofing Options We Install

  • Rubber Membrane Roofing (EPDM)

    A high-performance roofing system designed to fully seal and protect low slope areas.

    • Made from durable synthetic rubber designed for waterproofing

    • Installed in large sheets to minimize seams and leak points

    • Flexible material that handles temperature swings without cracking

    • Proven long lifespan with minimal maintenance

    • Long lifespan (20–30+ years) with minimal maintenance

    Rubber membrane systems are one of the most widely used low slope solutions because they provide a continuous waterproof barrier and long-term performance. 

  • Asphalt Roll Roofing

    A cost-effective solution for smaller low slope areas.

    • Budget-friendly roofing solution

    • Quick and efficient installation

    • Ideal for porches, sheds, and small additions

    • Reliable protection for low slope applications

    Roll roofing is often used when homeowners in NH need a straightforward, affordable solution for smaller low-slope areas.

Why Low slope roofing matters?

  • Incorrect materials lead to leaks

    Using shingles instead of flat or low slope roofing systems can cause serious water intrusion issues.

  • Membrane systems create a sealed surface

    Instead of overlapping pieces like shingles, low slope systems are designed to act as one continuous waterproof layer.

  • Every roof is different

    Low slope roofing is always installed based on the structure, pitch, and layout of your home; there is never a one-size-fits-all approach.
