Roofing Systems Guarantee, Technical and Warranty Services
Working with today’s commercial roofs is more complex than ever and requires considerable technical and industry knowledge. At Johns Manville, we emphasize the roof as a complete system. JM’s financial strength allows us to provide some of the strongest and most comprehensive guarantees in the roofing industry. We offer roofing warranties and 10-, 15-, 20-, 25- and 30-year No Dollar Limit (NDL) roofing guarantees, depending on the roof system selected. Even if you never have cause to fall back on the JM Peak Advantage® Guarantee, Johns Manville Roofing Systems provides you with additional value by offering technical assistance to the building owner throughout the life of the agreement.
By purchasing a Peak Advantage Guarantee, you get:
- Expert installation by approved JM contractors
- Advanced technical assistance
- Timely issuance of all guarantee documents
- Efficient processing of any claims or complaints
- Prompt service from highly trained personnel
Technical Services IN the Field
To ensure the quality of the roofing installation, our technical field staff around the country monitors roofing applications during installation and makes a final inspection on each guaranteed roofing system upon completion. These roofing experts ensure the roofing system meets all the qualifications for a JM Peak Advantage Guarantee.

Roof Maintenance
Keep in mind that your roof still needs to be maintained. We suggest to inspecting your roof twice a year as weather and unseen issues can cause problems on your roof.
Here we provide a checklist to keep as a reminder on things to look for on your roof. Use this as a guideline for semi-annual maintenance, and maintain the records to help ensure the integrity of your roofing system.
Preventative Maintenance Guidelines
Guarantee Extension Program
As much as we would like them to, today’s buildings don’t last forever. Wear and tear occurs, and when that happens, decisions about whether to invest in the repair or replacement of materials have to be made. Johns Manville’s Peak Life Program is designed to maximize the value of your roofing investment by providing guarantee extensions and coordinating maintenance. Initiating a regular inspection and maintenance schedule places you on a path to a better performing asset with more options at the end of the Guarantee term. Peak Life Extensions offer owners a variety of options to extend the Guarantee term depending on their needs. By placing owners in direct contact with JM professionals, Peak Life enables you to make the best decisions for your building.
