We were subjected to Natural Slate Roofing and have many regrets. The work needed to be corrected by another roofer. The positives about them is the work fast and bring a large crew. The negative is they work fast, do not hang copper gutters properly causing water to not flow, they left a large pile of trash and debris, the clay tile workmanship was very amateur compared the the roofer we had fix their work and they did not return to finish the scope of work yet sent a full invoice. When we paid the invoice short hoping for their return to resolve, they sent a lien notice. They are the furthest from a company seeking 100% customer satisfaction as stated on the website. Allan will not return calls. I have an equally if not more dissatisfied neighbor about their work on their house. Beware.
