At the Delta Slate Company, we are all about our customers. Our first task is to assess, explain and advise on slate roofing issues, then listen. We provide expertise: a thorough knowledge of every kind of slate, its sourcing, availability and correct installation; a complete understanding of copper roofs; chimney, vent-pipe, ridge and valley flashings; sheet metal work and soldering. Our foremen and helpers are courteous and show respect toward our customers and their property. They are proud of their trade-skills and appreciate the opportunity to practice them. But without question, as a company, we work on the proven principle that what is best for our customers is always best for us.
