How to Get an Existing Commercial Roof Under New Warranty?

Your roof's warranty has expired — or is about to. You don't want to pay for a full replacement, but you need ongoing warranty protection. Here's how a coating restoration gets your roof under a new manufacturer's warranty.

The Requirements

To qualify for a new manufacturer's warranty through restoration, three conditions must be met: the existing membrane must be in acceptable condition (not delaminating or extensively failed), wet insulation must be removed and replaced, and the work must be performed by a manufacturer-approved contractor using approved materials.

The Process

A qualified contractor performs a thorough inspection with core samples to assess moisture levels. Wet sections are replaced. The existing surface is power-washed and repaired. A coating system is applied at the required mil thickness — and the manufacturer issues a new 10–20-year warranty.

Cost vs. Replacement

Getting an existing roof under a new warranty through coating restoration typically costs 50–70% less than a full replacement. For building owners who need warranty coverage but aren't ready for a major capital expense, restoration is often the clear solution.

What Warranty Length Is Available?

Most manufacturers offer 10, 15, or 20-year warranty options depending on coating thickness applied. Thicker coating = longer warranty. A contractor can help you choose the right option based on your budget and timeline goals.
