Johns Manville Roof TechXpert

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 and strive to provide quality products, tools and support to assist roofing professionals. This app is designed to assist you in using Johns Manville roofing products to achieve high performing, long lasting roofing systems.


The JM Roof TechXpert app features several useful tools to assist roofing applicators at the job site. Tools include a built-in adhesive advisor that gauges approximate flash times by calculating real time temperature and humidity climate data at your location. The application's reference library delivers technical information about JM products as well as application information and how to trouble-shoot roofing challenges. The tool also features a tech rep locator so you can find the JM tech rep nearest your job site.
