Flat Roof Installation – Harrow

GRP fibreglass flat roof in Harrow

The homeowner was experiencing persistent leaks and poor insulation due to an ageing felt roof. They required a modern, durable and low-maintenance solution to protect their property. We recommended a GRP fibreglass system, known for its strength, longevity and waterproofing properties.

Our team carefully removed the old roof, prepared the surface and installed the new system, ensuring a seamless, leak-proof finish that enhances the property's energy efficiency.

Step by step

• Initial inspection & consultation – Identified damage and assessed requirements.
• Old roof removal – Stripped back the existing felt roof and disposed of materials responsibly.
• Surface preparation – Installed a new OSB deck and ensured a level base.
• GRP fibreglass installation – Applied resin and fibreglass matting, followed by a durable topcoat.
• Edge trims & drainage upgrade – Installed trims and ensured proper water runoff.
• Final checks & customer approval – Conducted quality inspections and handed over the finished roof.

The result

• The GRP system offers a seamless, joint-free surface, reducing the risk of leaks.
• Increased thermal efficiency, helping the homeowner reduce energy costs.
• Low-maintenance and highly durable, with a lifespan of 30+ years.
