How long does a GRP flat roof actually last?

We frequently answer questions from homeowners comparing different flat roofing materials. Here are some of the most common queries we receive about GRP fibreglass:How long does a GRP flat roof last? A professionally installed fibreglass roof can comfortably last 30 years or more, significantly outperforming traditional felt coverings.Can you install GRP in the winter? Fibreglass requires dry, relatively mild conditions to cure correctly. While summer offers the ideal conditions for new installations, we closely monitor the weather to find safe, dry windows for winter projects.Which is better: GRP or EPDM rubber? Both are excellent, modern alternatives to felt. GRP is rigid, highly impact-resistant, and great for balconies. EPDM is a flexible rubber membrane that is excellent for accommodating building movement. We can advise on the best option during your free consultation.

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.
