Over the past 30 years castle mouldings have installed hundreds of fibreglass flat roofs, valleys and gutters on projects ranging from small bay windows up to large commercial units. Using only the highest quality materials coupled with experienced and knowledgable staff we aim to provide the customer with the best possible product - a roof that not only will provide an extremely tough, resilient and extremely long lasting waterproof covering, but will look good for years to come too!

All our work carries a 25 year guarantee against faulty workmanship or materials - although the lifespan of a GRP roof far exceed this.

With a variety of finishes available, such as non slip, rolled lead effect,  solar reflective or custom colours, we work closely with our customers to accommodate their needs.
