WTSC is your answer to expensive factory-made perimeter edge flashings. Let us test your parts with our state-of-the-art testing apparatus to ensure compliance with the ANSI/SPRI ES-1 standard. All 50 states have adopted some version of the International Building Code that includes the requirement of ES-1 tested parts on commercial low-slope roofs. Isn’t it time to say “YES” to more projects?!

WTSC will provide all ANSI/SPRI ES-1 testing and final certifications utilizing our equipment. We will test the fabricated edge details that you produce in your shop at an economical cost per condition. Yearly ongoing facilities audits are performed each year to ensure that fabrication processes are being maintained. We charge for this service per audit plus travel. The cost is very economical and is an easy way to maintain compliance with building codes.
