Specification Support

We are here to support you

From dedicated technical project support to CPDs. We understand the challenges faced in the gutter and roof environment and how to help you specify the right system. We are always at the end of a phone to talk through your specific needs.

Making your Project Flow

We offer a full service support called Project Flow to guide you at every stage of the process. Starting with the specification process, we initially provide site surveys, condition reports and bespoke specification support, and then work hand in glove with our network of Approved Contractors during the installation process, then undertake rigorous site inspections and audits prior to authorising release of the systems guarantees. In this way, quality is assured for all project stakeholders.


We work with all key stakeholders to ensure the highest quality of installation and system specification. We work with installing contractors through rigorous training programmes and subsequent site inspection and audit regimes. We work with specifiers to deliver bespoke system specifications to stop leaks for good. This ensures the highest quality of gutter and roof refurbishment and total satisfaction for the end customer.

Technical Specification Support

We provide high levels of technical support with specifications, access to technical libraries (including technical information and system specifications), CPDs and dedicated system training programmes for specifiers and contractors.

Have you booked your CPD?

We have two accredited CPDs available:

"Why gutters fail and the options to repair, replace and refurbish: A specifier's guide"

"Metal roof refurbishment: A specifier’s guide to good practice"

These CPDs look specifically at commercial and industrial gutter and roof types and give a better understanding of the primary reasons why they fail, along with the refurbishment options available. Finally, we end with a purpose made mobile rig demonstration.
