Single Ply & GRP Roofing
GRP Roofing
GRP Roofing: Extreme Durability and Perfect Finish
GRP (Glass Reinforced Plastic) roofing, also known as fibreglass, is a robust, joint-free waterproofing system. It's applied in liquid form, reinforced with fibreglass, creating a monolithic layer that adheres perfectly to the surface.
At Three3col, we provide high-quality GRP installations to ensure long-lasting protection and a superior aesthetic finish.
Key Benefits of GRP:
Complete Waterproofing: With no joints, it eliminates weak points for leaks.
High Resistance: Withstands impacts, punctures, and is ideal for pedestrian traffic areas.
Long Lifespan: Designed to last over 20 years with minimal maintenance.
Chemical and UV Resistance: Maintains its integrity and colour in harsh conditions.
Clean Aesthetic: Offers a smooth, modern finish, available in various colours.
Ideal for:
Walkable terraces and balconies.
Flat roofs requiring maximum durability.
Areas with machinery on the roof.
With Three3col, you'll get a reliable, attractive, and low-maintenance GRP roof.






Single Ply Membranes
Single Ply Membranes: Lightweight, Flexible, and Highly Durable
Single Ply Roofing membranes are a cutting-edge and efficient solution for waterproofing flat and low-pitched roofs. These systems are known for being lightweight, highly flexible, and easy to install, offering robust protection with minimal impact on the building's structure.
At 3 col, we work with the most recognised and highest quality types:
EPDM: A synthetic rubber with exceptional elasticity and UV resistance. It's ideal for roofs that need to adapt to structural movements and temperature fluctuations.
TPO: Composed of polyolefin and rubber, this material stands out for its high chemical resistance and ability to reflect sunlight, contributing to the building's energy efficiency. Its seams are heat-welded for extra security.
PVC: Extremely versatile and resistant to a wide range of chemicals and greases. Like TPO, it's joined by thermal fusion, ensuring continuous and seamless waterproofing.
Key Benefits of Single Ply Membranes:
Quick Installation: Their lightweight nature and single-layer design allow for a swift installation process, reducing project timelines.
Great Adaptability: Their superior flexibility allows them to conform to structural movements without cracking.
Long Lifespan: They offer high resistance to weathering and UV radiation, ensuring long-lasting protection.
Low Maintenance: Their smooth surface makes inspections and any spot repairs easy.
Energy Efficiency: Light-coloured membranes reflect heat, helping to reduce building cooling costs.
Ideal Applications:
Flat and low-pitched roofs on commercial, industrial, and residential buildings.
Renovation projects seeking a lightweight and efficient solution.
Green roofs, thanks to their proven root resistance.
