Quality Assured Contractor Programme

National Network of Roofing Experts

When specifying Sika Liquid Plastics products we recommend the use of our Quality Assured Contractor Programme, which is made up of audited roofing contractors based throughout the UK.

Guaranteed Quality

The programme offers clients guaranteed quality and assurance because all QA Contractors have received full training from us in all application techniques in order to help them meet our stringent standards.


To promote strict professionalism amongst our roofing contractors, the QA programme also has demanding entry criteria along with a stringent code of practice. Members undergo regular office audits to ensure that the company has a sound corporate identity and follows excellent working practices.

Freedom of Choice

Where possible we will always recommend a selection of QA Contractors for your project, giving you freedom of choice with a guarantee of quality workmanship.
