APPROVED CONTRACTORS FOR:

Commercial Roofing solutions for your Business

Due to the latest building regulations, non – combustible materials are required on roof installations.

Bitumen Waterproofing

The robust nature of Bitumen Waterproofing Membrane makes these types of roofs resistant to punctures, scratches, and impact damage, meaning they are incredibly long-lasting. 

There are many methods for installing bitumen membrane systems. This includes the torch-on-bitumen method as well as fixing or adhering to the system. At Protech Roofing, we are experienced in fitting and maintaining bitumen membrane roofs. Our expert team can tell you the best installation method for your project.

 

Single Ply Membrane

Not only is the single ply membrane durable and weather resistant but it is also exceptionally lightweight, eight in at around 3kg per metre. If your project has weight and load-bearing considerations, then this is the perfect solution. With over 27 years of experience, Protech Roofing has provided waterproofing services for many reputable projects.

In 2017, Protech was awarded the Best Refurbishment Award by the SPRA (Single-Ply Roofing Association).

 

Hot Melt Roofing System

Hot-melt roofing systems work by applying hot liquid to the prepared roof to create a completely seamless, monolithic layer. This works to protect the roof from rain, snow, frost, and other damage. At Protech Roofing, we partner with some of the best hot-melt waterproofing suppliers and providers in the industry, including IKO and Bauder. 

Aluminium Terrace Decking is the perfect choice for terraces, balconies, and walkways. It has excellent spanning capabilities, quick installations and is guaranteed for 20 years
