What is a GRP Flat Roof?

GRP flat roofs (sometimes referred to as fibreglass roofs) are one of the most popular flat roofing solutions available from Jacob James Roofing. GRP stands for Glass Reinforced Polyester and is a composite material formed by strengthening plastic using fine fibres made of glass. The single-ply laminate has been used as a reliable type of covering and waterproofing for roofs for over 60 years. GRP has also been used on a wide array of other applications such as boats, lorries, water tanks and ponds plus more commonly on commercial and domestic buildings. Many of our clients choose GRP roofing systems because of their simplicity and safety plus the finished product has a long lifespan.

Reasons to Choose Fibreglass Roofing

Fibreglass roofing has become very popular across UK construction, here are some reasons why our customers are opting for this type of roofing system – 1. Durability – GRP roofs have a reputation for being strong and durable meaning they will last for years to come. 2. Weight – Fibreglass roofs are lightweight and more environmentally friendly compared to other roofing systems. 3. No Joints – Because the material is in liquid form it means there are no joints or seams on the roof’s surface after it is installed. This creates a smooth finish that any other roofing system cannot achieve. 4. Repairs – Repairs for fibreglass roofs are easy because of the material being used. Maintenance can also be carried out quite easily. 5. Aesthetics – Fibreglass comes in a number of colours that provides plenty of choice for property owners. It is much easier to match your new roofing with an established colour scheme using GRP roofs.

How to Lay GRP Flat Roofs

GRP flat roofs start with a layer of catalysed resin being applied to the high-quality roof decking. A layer of fibreglass mating will then be laid on top followed by another layer of catalysed resin to complete the roofing system. Once cured, a fire retardant topcoat resin will then be applied to weatherproof the roof and provide an attractive finish. Bespoke designed edge trims and drip trims are fitted to the edges of the roof and abutments before the GRP roofing is laid down.

How Much Does a GRP Roof Cost?

The overall cost of a GRP roofing system depends on whether a new roof is being constructed or an existing roof is being altered or repaired, with the latter being cheaper. The surface area of the roof is one of the main considerations when budgeting for your new GRP roof. You will also need to consider if any structural repairs need to be carried out on the roof and if alterations are needed for guttering or downpipes. GRP roofing systems are considered more expensive than EPDM rubber roofing, but when you factor in its impressive longevity plus the lack of maintenance required, its weather resistance and attractive laminated finish; GRP flat roofs are definitely worth the investment.
