Fibreglass Flat Roofing
Our fibreglass flat roofing solutions provide durable, waterproof protection for residential and commercial properties. Using Glass Reinforced Plastic (GRP), we create seamless, joint-free roofs resistant to UV exposure, extreme temperatures, and foot traffic. Ideal for garages, extensions, and commercial buildings, these systems require minimal maintenance and come with a 25-year guarantee. The non-porous surface prevents water ingress, ensuring long-term structural integrity and energy efficiency.
Pond Lining
We install custom fibreglass pond liners that offer permanent, leak-proof solutions for garden ponds and water features. Our liners resist punctures, UV degradation, and chemical damage while maintaining safety for aquatic life. The flexible design allows integration of waterfalls, steps, and filtration systems, with a range of finish options to complement your outdoor space. This durable solution eliminates the need for frequent replacements associated with traditional liners.
Warm Roof Insulation
Warm roof insulation systems improve energy efficiency by placing insulation above the roof deck. This method reduces heat loss, prevents condensation, and extends roof lifespan. Ideal for both new builds and renovations, our warm roof solutions enhance thermal performance while maintaining compliance with building regulations. The system ensures optimal temperature control and reduced energy bills for residential and commercial properties.
Cold Roof Insulation
Cold roof systems feature insulation between roof joists with ventilated airspace to prevent moisture buildup. This cost-effective solution suits shallow roof spaces and existing structures requiring improved thermal performance. Our installations balance ventilation and insulation to mitigate condensation risks while maintaining structural integrity. Particularly suited to period properties and budget-conscious projects across the West Midlands.
Roof Repairs
We provide rapid-response flat roof repairs for urgent leaks, storm damage, and structural issues. Our team addresses cracks, blisters, and water ingress using compatible materials to ensure seamless integration with existing systems. Emergency services prioritise immediate protection against weather damage, with long-term solutions to prevent recurrence. Regular maintenance plans are available to extend roof lifespan and avoid costly interventions.
