Why Join National Slate Association?

National Slate Association

The National Slate Association appreciates the history, beauty, and proven nature of natural slate while dedicating it to the mission of supporting it as a material. Other materials feel wasteful and inferior compared to the longevity and eco-friendly nature of slate. The National Slate Association has come together to promote and educate how to use natural slate as a roofing material. By joining, you’re engaging in a community of like-minded people who respect the centuries-long tradition of slate installation. Learn installation specifics from the brightest minds the industry has to offer or shake hands with suppliers who will keep you competitive in the trade. Be listed in the NSA Member Directory as a qualified business in the industry. These are all benefits of joining this prestigious association.

National Slate Industry Resources

Comprehensive Slate Industry Resources, Guides, Videos & Technical Support – All in One Place

The National Slate Association Manual, released in 2010, is the leading resource for slate as a material and best practice roof installation techniques. Not only will you have access to the people who helped create this manual, but you also receive technical updates/bulletins on updated latest trends within the industry. This information pairs nicely with support for architects who are specifying slate as a material and educating the homeowner about what are the benefits of a slate roof. The National Slate Association also puts resources towards educating its audience with tutorial videos, plus a Mobile Field Guide that is useful for on-the-job installation support.
