At Bolsover Roofing Company, we specialise in high-performance GRP flat roofing systems for residential and commercial properties across Chesterfield and the surrounding areas. Also known as fibreglass roofing, GRP (Glass Reinforced Plastic) is a durable, seamless and low-maintenance solution designed to provide long-lasting protection against the British weather.

As a reputable team of roofing contractors in Chesterfield, we are known for delivering expertly finished GRP systems that are built to stand the test of time.

What Is GRP Flat Roofing?

GRP flat roofing is a modern roofing system formed by applying layers of fibreglass matting and resin to create a fully bonded, watertight surface. Once cured, it forms a strong, seamless membrane with no joins or weak points.

This advanced system is ideal for:

  • Home extensions
  • Garages
  • Dormer roofs
  • Garden rooms and offices
  • Balconies and walkways
  • Commercial premises

Unlike traditional felt roofing, GRP does not blister, split or degrade quickly. Its clean, smooth finish also enhances the overall property appearance.

Benefits of GRP Flat Roofing

Choosing GRP flat roofing offers numerous advantages:

  • Exceptional Durability – GRP roofs are highly resistant to cracking, shrinking and weather damage. When professionally installed, they can last 20–30 years or more.
  • Completely Seamless Finish – With no joints or overlaps, the risk of water ingress is significantly reduced.
  • Low Maintenance – Fibreglass roofing requires minimal upkeep compared to felt or asphalt systems.
  • Weather Resistant – GRP performs exceptionally well in heavy rain, frost and UV exposure, making it ideal for the UK climate.
  • Modern Appearance – The smooth, uniform finish provides a clean and contemporary look suitable for both domestic and commercial buildings.

At Bolsover Roofing Company, we follow a meticulous installation process to ensure maximum performance and longevity. As a team, we prepare each roof deck thoroughly, apply high-quality materials, and finish with a durable topcoat for enhanced protection.

Every project is completed to strict industry standards, ensuring:

  • Proper drainage and fall
  • Secure edge detailing
  • Reinforced corners and trims
  • A fully bonded waterproof membrane

We work efficiently while maintaining exceptional skills, ensuring minimal disruption to our customers and their properties.

GRP Flat Roof Repairs and Replacements

When a flat roof is leaking, sagging or showing signs of deterioration, we provide comprehensive inspections and honest advice. In many cases, replacing an outdated felt system with a new GRP roof offers a more cost-effective long-term solution.

As time-served roofing specialists, we start by accurately assessing each structure, recommending the most suitable approach, and carrying out the work with precision and care.
