GRP Flat Roofing Replacement Boston, Spalding, Peterborough

Signs Your GRP Roof Needs Replacing

Fibreglass roofs begin to fail when cracks, splits or worn patches appear, allowing water to soak into the boards beneath. You may also notice lifting edges, soft spots, damp marks inside the property or pooling after rain. 

These signs usually mean the surface is no longer bonded securely and can no longer protect the roof structure.

When these issues become regular, replacing the GRP system is the most effective way to restore strength, prevent leaks and ensure long term reliability.

Trusted Across Lincolnshire

Fibreglass Flat Roof Replacement Services

Our replacement service removes ageing flat roof materials, checks timber conditions and installs a new GRP laminate system that bonds securely for long lasting strength. Every stage is completed with care, from re boarding to edge trims and finishing coats.

The result is a durable, watertight fibreglass roof suitable for homes, extensions, garages and commercial properties.

Full fibreglass flat roof replacement

We carry out complete GRP flat roof replacement that removes all weakened materials and rebuilds the surface with new boards, trims and a fresh fibreglass system. 

This restores the structure, prevents recurring leaks and gives your property a smooth, long lasting and dependable finish.

Removal of old roofing materials

All worn roofing layers are stripped back, including felt, asphalt, vegetation and damaged boards.

Removing these materials allows us to check the timbers, improve drainage and create a clean surface for the new GRP laminate. This ensures your replacement roof bonds securely and performs reliably.

Installation of new GRP laminate system

The new GRP system is applied as a wet lay process using resin and fibreglass matting that bonds together as one solid layer.

This creates a seamless, durable and watertight surface that withstands weathering, resists cracking and offers long term protection for homes and extensions.

Fibreglass trims and edge detailing

We install pre formed GRP trims around the roof edges to direct water correctly and prevent pooling or overspill.

These trims provide essential protection, support proper drainage and give the roof a clean, accurate finish that strengthens the overall durability of your new GRP system.

Roof insulation upgrades

During replacement, we can add insulation beneath the new GRP system to improve heat retention and energy efficiency. 

Upgrading insulation at this stage creates a warmer, more efficient property while ensuring the new fibreglass surface is supported by a secure and correctly prepared structure.

Protective topcoat application

Every replacement roof is finished with a tough polyester topcoat that improves durability, weather resistance and overall appearance.

This protective layer shields the laminate from UV exposure, impacts and daily wear, helping the roof stay clean, strong and watertight for many years.

35+ Years Experience


What Is GRP Flat Roofing

GRP flat roofing is a fibreglass system made from layers of resin, reinforced matting and a protective topcoat that bond together to form a solid, seamless surface. 

It is watertight, weather resistant and suitable for both domestic and commercial buildings.

The material does not crack easily, requires very little maintenance and performs well in changing temperatures. Many properties in Boston choose GRP because it provides long lasting reliability and strong protection for a wide range of flat roof structures.
