How Our Flat Roofing Process Works.
1. Free Site Visit & Comprehensive Roof Assessment
2. Fixed, Fully Detailed & Transparent Quotation
3. Professional Installation by Specialist Fibreglass Installers
4. Final Quality Checks, Clean-Up & Workmanship Guarantee
1. We begin with a free, no-obligation site visit anywhere in Kent.
During this visit, our specialist will:
Assess the condition of your existing roof
Identify any visible issues such as leaks, cracks, blistering, rotten decking or poor drainage
Measure the roof and confirm access points
Check whether a repair, overlay, or full replacement is the most cost-effective option
Discuss warm roof options (insulation + vapour control layers) if suitable
Explain the installation process clearly so you know exactly what to expect
You’ll also have the opportunity to ask any questions, compare options and receive honest advice based on what’s best for your home — not what’s most expensive.
2. Fixed, Fully Detailed & Transparent Quotation
Once your assessment is complete, we prepare a clear written quotation that includes:
The full specification of the materials
Details of decking, vapour control layer, PIR insulation (if chosen)
Fibreglass laminate system and UV topcoat
Waste removal and preparation work
Expected installation timeframe
Weather considerations
Workmanship guarantee details
You’ll always know exactly what you are paying for, why we recommend certain materials, and how long the project will take.
There are no hidden extras or surprise charges — everything is agreed upfront.
3. Professional Installation by Specialist Fibreglass Installers
When you choose to move forward, we book your job into our schedule and begin installation on the agreed date.
Our trained specialists will:
Prepare and secure the roof decking
Install vapour control layers and insulation (if required)
Apply the fibreglass laminate system seamlessly across the entire roof
Fit all trims, edge details and drip systems
Finish the job with a high-performance UV-stable topcoat in your chosen colour
Throughout the process:
We keep you updated every step of the way
We maintain a clean and tidy workspace
We complete all work in accordance with best industry practice
Weather dependency:
Fibreglass roofing requires dry conditions and appropriate temperatures. If the weather isn’t suitable, we will contact you immediately, adjust the schedule and ensure your roof is installed under the right conditions for a perfect finish.
4. Final Quality Checks, Clean-Up & Workmanship Guarantee
Once the fibreglass system has cured, we conduct a full quality inspection, ensuring:
All trims and edges are watertight
The roof surface is smooth, seamless and properly finished
All areas meet our high installation standards
The site is cleaned, cleared and left tidy
We then walk you through the completed roof, answer any final questions, and provide your workmanship guarantee certificate, which you can keep with your home documents for future reference or property sales.
Your roof is now protected with a long-lasting, seamless, waterproof system designed to perform for decades.

Flat Roofing FAQs
Click below to find out more
A. A high-quality fibreglass (GRP) flat roof from Fibre Form can last 25–30 years or even longer with very little maintenance. Because it’s installed as a single, seamless, fully waterproof system, it avoids the common problems found with traditional felt roofs, such as split joins and water ingress. This makes fibreglass one of the most durable and cost-effective roofing options for homeowners across Kent.
A. Yes. Fibreglass is generally stronger, longer-lasting and more durable than felt or EPDM. It’s applied as a single seamless membrane, eliminating weak points where water can penetrate. It also offers better fire resistance, UV stability, and overall lifespan compared to traditional flat roofing methods.
A. Yes. All new fibreglass flat roofs we install come with a full workmanship guarantee. The length of the guarantee is detailed in your quote and depends on the type of system installed. You’ll receive your guarantee certificate on completion for future home sales or insurance documentation.
A. Yes. Fibreglass requires the correct weather conditions — dry and within a suitable temperature range — to cure properly. If the weather changes, we’ll reschedule and keep you fully updated. This ensures your roof is installed to the highest standard with a perfect finish.
A. In many cases, yes. We can repair minor cracks, small leaks, and damaged sections. During your roof assessment, we’ll advise whether a repair, overlay, or full replacement is the most cost-effective and reliable option. Our goal is always to recommend the best solution for your situation, not the most expensive one.
A. Costs vary depending on the size of the roof, condition of the existing decking, insulation requirements, and the build-up needed. We keep our pricing as competitive as possible, while ensuring enough budget to use premium materials and complete the job to a high standard. Every customer receives a fixed, transparent written quote with no hidden extras.
A. Yes. A fibreglass roof is ideal for a warm roof build, which includes PIR insulation and a vapour control layer. This helps reduce heat loss, improve energy efficiency, and prevent condensation inside your property. Warm roofs are popular for extensions, garage conversions, and newly renovated areas.
A. We provide flat roofing services across all of Kent, including Ashford, Maidstone, Canterbury, Folkestone, Dover, Tenterden, Tonbridge, Tunbridge Wells, Sittingbourne, Chatham, Gillingham, Herne Bay, Whitstable and all surrounding villages. If you’re unsure whether we cover your area, just give us a call — we most likely do.
