How Our GRP Flat Roof Installation Works

How Our GRP Flat Roof Installation WorksWe manage every stage of your fibreglass roofing project, from the initial structural assessment to the final weather-resistant topcoat. Here is exactly what you can expect when you choose us for your Swanley flat roofing project:Comprehensive Survey: We begin by thoroughly inspecting your existing roof to check for water ingress, rot, or structural damage beneath the surface.Structural Deck Replacement: A successful GRP roof requires a solid, dry foundation. We strip away the old, failing materials and install a brand-new, high-quality OSB3 timber deck to ensure optimal adhesion.Applying the Base Coat: We carefully apply the catalysed resin and fibreglass matting. This cold-applied process requires no heat or open flames, making it exceptionally safe for residential properties.Seamless Topcoat Finish: Once the base layer has cured, we apply a durable, UV-resistant topcoat. This creates a highly attractive, completely maintenance-free waterproof barrier.

Why Choose Kevington for GRP Fibreglass Roofing in Swanley & Kent?

Why Choose a Fibreglass Flat Roof?

Why Choose a Fibreglass Flat Roof for Your Property?Upgrading to a glass reinforced plastic roof is a smart investment for any homeowner in Sevenoaks or Swanley. Traditional felt roofs often blister, crack, and fail over time, whereas GRP provides long-term peace of mind and superior weather resistance.Completely Seamless: Because the material is applied as a liquid, there are no joints, laps, or seams where water can penetrate, making leak prevention incredibly effective.Exceptional Durability: Fibreglass is tough enough to withstand heavy foot traffic, making it an ideal choice for balconies, walkways, or roof terraces.Enhanced Thermal Efficiency: When combined with modern warm roof insulation, a GRP system drastically improves your home's energy efficiency, helping to reduce winter heating bills.Zero Maintenance: Once installed and cured, your new flat roof will not require the constant patching and repairs associated with older felt materials.If you suspect your current flat roof is failing, do not wait for water ingress to damage your internal ceilings. Contact our Kent roofing contractors to discuss a replacement.

Frequently Asked Questions About GRP Roofing

Frequently Asked Questions About GRP RoofingHow long does a GRP fibreglass roof last? When installed correctly onto a fresh timber deck, a high-quality fibreglass roof can easily last for over 30 years with virtually zero maintenance.Is a GRP roof better than EPDM rubber? Both are excellent options. However, GRP is highly impact-resistant and better suited if your roof will experience regular foot traffic or if you are planning to use the space as a balcony.Can you repair an existing GRP roof? Yes, if your fibreglass roof has suffered isolated impact damage (such as a falling branch), we can easily clean, prepare, and re-coat the specific area without needing to replace the entire roof structure.Does a GRP roof smell during installation? There is a distinct resin odour while the base coat is being applied and curing. However, this dissipates very quickly once the roof is fully cured, usually within 24 hours.

GRP Fibreglass FAQs

Frequently Asked Questions About GRP Flat Roofing

Got questions about upgrading or repairing your flat roof? Kevington Roofing and Building LTD provides expert answers on our durable, cold-applied liquid membrane systems for homes across Croydon & South London, Swanley, Sevenoaks, and Kent.

How much does a new GRP fibreglass roof cost in Swanley?

+

The cost of a fibreglass roof replacement in Kent depends on the size of the area and the condition of the underlying timbers. Generally, while the initial cost is slightly higher than felt, the fact that it lasts twice as long makes it the most cost-effective flat roof installation in the long run. We provide free, itemised quotes so you can see exactly where your money is going.

Can a GRP roof be installed in any weather?

+

Fibreglass needs dry conditions to cure correctly. While we can work throughout the year in Swanley, we carefully monitor the weather. We will never start a resin application if rain is forecast, as this would compromise the waterproof seal. Our team uses temporary coverings to keep your home dry at all times during the process.

Is GRP roofing noisy when it rains?

+

This is a common myth. When installed correctly with high-quality OSB3 decking and proper insulation, a GRP roof is no noisier than any other roofing material. In fact, many homeowners find it quieter than old thin felt roofs because of the solid timber base we install underneath the laminate.

How long will the installation take?

+

Most domestic flat roofs in Swanley, such as a standard garage or kitchen extension, can be completed in one to two days. We aim to work efficiently to minimise disruption to your daily routine, and we always make sure the site is safe and secure at the end of each day.
