Why Choose Us

Why choose GRP for your flat roof?

Unlike traditional multi-layer mineral felt, which can crack and fail over time, GRP fibreglass is a cold-applied system that forms a single, joint-free barrier. This seamless construction prevents the common issue of water ingress at the seams, which is the primary cause of leaks in many local flat roofs. Because the application process requires no open flames, it is a safer option for your property, and the resulting finish is robust enough to handle occasional foot traffic while resisting UV degradation.

Who We Are

Addressing common flat roof problems in Surrey Heath

Many properties across Frimley and Surrey Heath suffer from water pooling on aged, uneven flat roof surfaces. If your current roof is showing signs of sagging, moss growth, or internal staining, it is time for an inspection. We evaluate the structural integrity of your roof deck and the existing falls to ensure that water drains effectively. By upgrading to a modern GRP system, we resolve persistent damp issues and protect the underlying structure of your building from further deterioration.

Do you need a full replacement or a repair?

We offer thorough site surveys to determine the most cost-effective and practical solution for your home. While some minor issues may be addressed with targeted repairs, extensive degradation often necessitates a full replacement to restore full weatherproofing. When replacing your roof covering, we always consider current Building Regulations Part L requirements. If the scope of work qualifies, we ensure your insulation is upgraded to meet today’s thermal performance standards, helping to keep your home warmer and more energy-efficient.
