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. Our highly skilled technicians and engineers provide essential support services throughout the project life cycle—from the early design stages to the completion of the bid package. Support services can include: conceptual product information, building science, wind uplift data, national and local code understanding, FM Global® and UL® regulations, fastening patterns and sheet layouts, installation guidelines and standard details.
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
To ensure the quality of the roofing installation, JM's field technical 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.
