Not all contractors are created equal

The bitterness of poor quality remains long after the sweetness of a low price is forgotten

Replacing a tired leaking roof or improving the look of your property usually represents a significant financial investment. The consumer needs to be sure that the products and services they invest in represent the highest possible standards.

We've all heard the stories of rogue contractors, they're in every industry and our approved contractors are called out regularly to help the victims.

The common problems associated with failed installations are down to the use of inferior grade materials and poor quality installation. By the time you get an issue with your new roof, the contractor will either want nothing to do with you or may not even be trading anymore.

Each time this happens it causes no end of stress and upheaval, we've seen homes damaged, possessions ruined and tempers frayed.

Allbase marries our high-grade advanced systems with a nationwide network of trained and approved contractors to deliver an unparalleled experience that delivers on both quality and workmanship.


Whether you’re looking for a GRP roofing installer for home extensions, garages, dormer roofs, conservatories, orangeries and more, our nationwide network of trained and approved contractors have the knowledge and expertise to install your new fibreglass roof to an exacting standard.


Our experienced contractors are regularly trained and updated on the latest changes within the industry and are happy to answer any questions you may have. From the GRP roofing system itself to insulation, building regulations, health and safety and beyond.

Professional standards
