Great vendor for my roofing company. They had what we needed in stock and the shipment arrived on time. Next time I need Slate Roofing materials/tools this is where I'm going to get them from.

The items I ordered shipped the next morning. I received them two days earlier Then I expected… Which worked out great because the weather was not as bad as predicted, and I could start my job sooner. The slate roof repair items that I ordered are very good quality! I will definitely be back to order more items as my slate roof needs repair! Great customer service and high-quality. What more can someone ask?

I’ve had a great experience with John Stortz tools. The build quality is excellent, and the tools are clearly designed with professional use in mind. They feel solid in hand, work efficiently, and hold up well over time, even with regular use. Customer service was responsive and helpful when I had questions, and shipping was prompt. Overall, John Stortz provides reliable, well-crafted tools that I would confidently recommend to anyone looking for durable, high-quality equipment.
