Trained Contractor Network

Ensuring quality control

To ensure the highest level of installation quality control, we operate a national network of certified Trained Contractors fully qualified in the installation of our systems. Sharman’s team of external Technical Services Managers work hand in glove with these Trained Contractor partners carrying out inspection and audit and or site certification for all projects as a precondition of authorising the gutter and roof systems guarantees.


Becoming a Trained Contractor

In support of the NFRC’s drive to improve quality standards across the roofing industry, our contractor partners undertake an initial comprehensive and rigorous gutter and roof refurbishment training programme supported by online training resources and project audit.

Correct installation in line with Sharmans installation  methodologies is a key requirement of the lifecycle performance and the authorising of the gutter and roof systems guarantees.
