The American Society for Testing and Materials (ASTM) groups roofing slate into 3 grades—S1, S2, or S3 based on breaking load, water absorption, and depth of softening. The highest grade is S1 with a service life of more than 75 years. New England Slate tests our slate to ensure compliance with ASTM S1.
We believe quality starts with the stone. We select only ASTM S1 grade slate from the premier quarries in the Vermont/New York slate valley, Virginia, Quebec, Wales, and Spain.
New England Slate offers a warranty on all our slate that the service life will exceed 75 years.
Our craftsmen cut, trim, sound, orientate and punch each piece of slate before it is carefully stacked, banded and shipped. Taking this pride and care in our work reduces costs for our customers by minimizing breakage and waste.
New England Slate is a family-owned business that has employed only the most skilled craftsmen in the valley for over 30 years. We believe in setting high standards for ourselves and our slate; a difference you can see and feel.
More than vendors, we are partners who offer true color descriptions, accurate lead-times, and value added pricing. We know that our value depends on being reliable and trustworthy.
New England Slate doesn’t just believe in customer service, we believe in customer success. We know success requires hard work, persistence and a little creativity.

“Good morning. Slate has arrived in Newburyport, Mass. I just wanted to thank you for sticking with me and making sure everything went so smoothly with the new slate quarried and delivered to St. Paul’s Church. The truck is here (early, which is great for me, cause I’m always early and punctual). Thanks again, we are grateful for New England Slate company supplying us with the beautiful Vermont slate. We now have our work cut out for us to get this roof installed. Have a great day.”
