Innovation in Roofing Technology

By working with advanced materials and the latest installation techniques, KNJ Roofing delivers roofing systems that are not only highly effective but also visually refined. These solutions are designed to offer long-term performance while supporting improved energy efficiency and sustainability.

Tailored Systems for Every Property

Specialising in GRP fibreglass roofing, KNJ Roofing offers a versatile selection of flat roofing options to suit a variety of budgets and structural requirements. In addition to waterproofing systems, the company also provides roofline services, including fascias, soffits and guttering, ensuring a complete exterior solution.

Why GRP Roofing Has Become a Leading Choice

For decades, traditional bitumen-based systems were widely used across the industry. While effective, the need for longer-lasting and more visually appealing alternatives led to the rise of GRP roofing.

GRP, commonly known as fibreglass, is a composite material formed by combining a durable resin with fine strands of glass fibre. This creates a strong yet lightweight surface that can be shaped and adapted to suit virtually any roof design.

Key Benefits of GRP Roofing

  • Exceptional strength combined with low weight 
  • Seamless, fully waterproof finish 
  • Flexible design options for various shapes and sizes 
  • Long lifespan with minimal maintenance 
  • Clean, modern appearance 

With its adaptability and performance, GRP has quickly become one of the most sought-after flat roofing solutions in the UK.

Long-Term Guarantees for Peace of Mind

KNJ Roofing offers extended guarantees on GRP systems, with coverage typically ranging from 20 to 35 years depending on the materials and specifications used. This ensures long-term confidence in both durability and performance.

The Importance of Quality Materials

Not all GRP roofing systems deliver the same results. KNJ Roofing places a strong emphasis on using premium, fully certified materials that meet industry standards.

Lower-cost alternatives, such as reprocessed or “re-blended” resins, are sometimes available in the market. While cheaper, these materials can contain inconsistencies or impurities that affect curing times, durability and overall lifespan. KNJ Roofing avoids such compromises, ensuring every installation benefits from reliable, high-grade components.

Built for Performance and Longevity

From initial consultation through to final installation, KNJ Roofing focuses on delivering flat roofing systems that combine technical excellence with long-term value. By prioritising quality workmanship and proven materials, the company provides property owners across the New Forest with roofing solutions designed to perform for decades.
