The Sika Liquid Plastics guarantee offers a single point of responsibility, and ensures that the client is protected against the failure of watertightness caused by incorrect design, defective materials or poor workmanship, through the issue of our Product/Extended Product Guarantee and Final Inspection Certificate. We believe this guarantee is the most comprehensive available in the roofing industry.

The guarantee can provide coverage for 10, 15, 20 and 25 years depending on the specification and when one of our Quality Assured Contractors completes the installation.

Also available is a Sika Liquid Plastics Material Guarantee which covers the material supplied. In this situation the contractor would self certificate their own workmanship.

Once the guarantee is issued to the contractor, an aftercare pack is provided to our clients with details on how to access their guarantee and further information on the maintenance of their roof.
