A correctly installed GRP roof lasts 25 to 30 years or more with no measurable deterioration. Regular maintenance — keeping gutters clear and sweeping the surface twice a year — extends that life further. Nottingham's freeze-thaw winters do not affect a well-installed GRP roof. Some systems carry manufacturer material guarantees of up to 25 years when installed by approved contractors.

Yes — GRP and fibreglass are the same product. GRP stands for Glass Reinforced Polyester, which is the correct trade term. You may also hear it called glass fibre roofing. All three names refer to the same system: fibreglass matting bonded with polyester resin and finished with a UV-stable topcoat.

The cost depends on the size of the roof, whether the existing deck needs replacing, whether insulation is required, and the access situation. We provide written, itemised quotes on every job after a FREE Drone Survey — so you know exactly what you are paying for before work begins. Call 0115-647-0560 to arrange your free survey.

It depends on the condition of the existing deck. If the deck is structurally sound, dry, and free of rot, a GRP layer can sometimes be applied over it. If the existing roof is damaged, blistered, or holding moisture, the old material must be stripped and the deck replaced before GRP goes down. We assess this during the FREE Drone Survey.

Most GRP flat roof replacements fall under Permitted Development Rights and need no planning application. Exceptions include properties in conservation areas such as The Park Estate, listed buildings, and properties where permitted development rights have been removed by an Article 4 Direction. If you are unsure, ask us before any work starts.

This is normal and is caused by thermal expansion and contraction. As the roof heats up during the day and cools overnight, the GRP surface moves slightly. Expansion joints fitted at installation reduce the noise significantly. If the sounds are new or louder than usual, it is worth having the roof checked.

Yes — as long as the correct specification is used at installation. Balconies and roof terraces need double-layer 450g matting or 600g matting, with anti-slip granules in the topcoat. If your current GRP roof was specified for no foot traffic, we can assess whether upgrading it is possible or whether a new installation is the right approach.

A warm roof places PIR insulation above the deck, under the GRP membrane. This prevents condensation forming in the roof build-up and meets current Part L Building Regulations for thermal performance. A cold roof places insulation between the joists and requires a ventilated air gap above. For new extensions and full replacements in Nottingham, we recommend a warm roof build-up — it performs better in the UK climate and avoids condensation problems long-term.

Yes — garage roofs are one of the most common GRP applications we carry out in Nottingham. A GRP garage roof is seamless, needs no maintenance beyond seasonal gutter clearing, and typically outlasts felt garage roofs by 15 or more years. If your garage roof is leaking or showing blistering and cracking, it is worth getting a FREE Drone Survey before spending money on patch repairs.

Most GRP roof damage can be repaired without full replacement. Pinholes, topcoat flaking, and isolated cracked sections can all be fixed by cutting out the damaged area, grinding back the surrounding GRP, relaying new matting and resin, and applying a fresh topcoat. Full replacement is only needed when alligatoring is widespread, the deck has rotted, or the roof is structurally compromised. Our FREE Drone Survey tells you which applies to your roof.

If your flat roof is leaking, cracking, coming to the end of its life — or you are planning a new extension and want a roof that performs for decades — this is the right time to call. We have been working on Nottingham roofs for over 20 years as part of Nottingham House Extensions. We have installed GRP fibreglass roofs on extensions, garages, dormers, and terraces across every part of the city — from West Bridgford and Beeston to Arnold, Hucknall, and Long Eaton.
