Black Cat Services Group provides fibreglass (GRP) flat roof installation and repair services across Guernsey, offering a durable and low-maintenance solution for a wide range of buildings.

Fibreglass roofing is a strong and weather-resistant system commonly used for extensions, garages, garden buildings, sheds, dormers, and other flat roof structures. When properly installed, GRP roofing creates a seamless waterproof surface designed to withstand the harsh coastal weather conditions often experienced in Guernsey.

We can carry out new fibreglass roof installations as well as repairs to existing GRP roofs, helping restore waterproof protection and extend the lifespan of the roof.

Services include:

• Installation of new fibreglass flat roofing systems
• Repairs to damaged or leaking fibreglass roofs
• Localised patch repairs and resealing
• Replacement of worn or damaged sections

Whether installing a new roof on a shed, extension, or outbuilding, or repairing an existing fibreglass roof that has begun to deteriorate, we provide a practical and reliable solution to help protect your property from water ingress and long-term damage.
