Our guarantee process reflects our commitment to excellence
The Siplast Guarantee issuance process is rigorous. It begins prior to material ordering and concludes with a successful final inspection by a Siplast Representative. This thorough review process is part of our commitment to be with you every step of the way.
Extend your guarantee coverage with our Encompass Program
We developed the Encompass Program to help owners build a specific regimen of regular maintenance and inspection, which are often overlooked. With proper measures in place from the beginning, it's possible for a properly managed Siplast roof to become eligible for extended terms without a gap in coverage.
