Flat Roofing Specialists

At The Flat Roofing Specialists, we recently completed a full flat roof replacement for a double garage and adjoining lean-to porch in Pay Street, Densole, Kent. The existing roof had reached the end of its lifespan, with ageing felt and polycarbonate sheeting no longer providing reliable protection against the elements. The homeowner was experiencing ongoing issues and wanted a long-term, cost-effective solution that would improve durability while still allowing natural light into the lean-to area.

Assessing the Existing Roof

Upon inspection, it was clear that both the felt roofing and polycarbonate sections had deteriorated significantly. This is a common issue across Kent, particularly in exposed and coastal areas where wind, rain, and UV exposure can accelerate wear and tear on older flat roofing systems.

Key issues identified included:

• Worn and failing felt covering
• Reduced weather resistance and risk of leaks
• Outdated polycarbonate panels offering poor insulation
• Roof structure requiring a solid, modern upgrade

Rather than carrying out temporary repairs, the customer opted for a full replacement to ensure long-term reliability and better performance.

Preparing the Roof Structure

The first stage of the project involved carefully removing the existing felt and polycarbonate materials. Once stripped back, we were able to assess the underlying structure and prepare it for a new, high-performance flat roofing system.

The roof was then fully re-boarded using 18mm OSB (Oriented Strand Board), creating a strong, stable base ready for the installation of a GRP fibreglass system. Proper boarding is essential in flat roofing, as it ensures the new system adheres correctly and performs as intended for years to come.

Installing the GRP Fibreglass Roofing System

GRP (Glass Reinforced Plastic), also known as fibreglass roofing, is one of the most durable and long-lasting flat roofing solutions available. It is particularly well-suited for garages, extensions, and porches where a seamless, watertight finish is essential.

The installation process included:

• Fitting high-quality perimeter edge trims for a clean, secure finish
• Installing trims around skylight openings to ensure watertight detailing
• Applying resin and reinforcing matting across the entire roof surface
• Carefully jointing all areas to eliminate weak points
• Finishing with a durable topcoat for UV protection and longevity

The result is a seamless, fully bonded surface with no joints or overlaps — significantly reducing the risk of future leaks.

Maintaining Natural Light with Cost-Effective Skylights

A key requirement for this project was maintaining natural light within the lean-to porch. The customer wanted a practical and budget-friendly solution without compromising the overall performance of the new roof.

We installed polycarbonate skylights within the new GRP system, allowing plenty of daylight to filter through the space below. This approach offers several benefits:

• Cost-effective compared to glass alternatives
• Lightweight and easy to integrate into the roofing system
• Provides immediate improvement in natural lighting
• Flexibility to upgrade to glass skylights in the future

This forward-thinking approach ensures the homeowner has the option to enhance insulation and thermal performance later, without needing a full roof replacement.

The Finished Result

The completed project has transformed both the double garage and lean-to porch. The new GRP fibreglass roof provides a clean, modern appearance while delivering exceptional durability and weather resistance.

The homeowner now benefits from:

• A long-lasting, low-maintenance flat roof system
• Improved protection against leaks and weather damage
• A brighter lean-to space thanks to integrated skylights
• Peace of mind with a professionally installed solution
