Why Choose Us

Why GRP Fibreglass is Ideal for Marlow Homes

Flat roofs often struggle with pooling water, particularly on shallow-pitched residential extensions. GRP fibreglass creates a seamless, monolithic membrane that eliminates the vulnerable joints where leaks typically develop in felt systems. Because it is a cold-applied process, we remove the fire risks associated with hot-torch alternatives. This material is highly resistant to UV degradation and can even support light foot traffic, making it a versatile choice for modern and period homes in the Marlow area.

Who We Are

Meeting Building Regulations and Thermal Standards

When replacing a flat roof, it is vital to consider current energy efficiency standards. We ensure all our installations align with Building Regulations Part L regarding thermal performance. This is particularly important for Marlow homeowners upgrading older extensions or outbuildings. By integrating correct insulation layers during your roof replacement, we help improve the heat retention of your living space while providing a watertight, long-lasting exterior finish.

Is your flat roof showing signs of failure?

If you notice interior staining, blistering on the roof surface, or consistent water pooling, your flat roof may be nearing the end of its lifespan. Our diagnostic process involves a thorough site survey to assess the underlying deck and determine whether a repair or a full replacement is the most cost-effective path. We understand the local building stock well, from post-war suburban designs to contemporary architecture, and we tailor our material application to ensure the roof performs reliably against the variable Thames Valley weather.
