Client Testimonials

"I think it's a incredible accomplishment for us all to have 2 acres of copper 55, copper FS, Bitumen, PVC and slate roofing systems working in conjunction with hundreds of details on some complicated skylights, multiple penetrations and several penthouses without a single leak or problem that I am aware of as I sit here today. This was all accomplished above some incredibly sensitive areas and all without adversely disrupting the daily operations of the (Massachusetts) State House."

James Sanderson, J.K. Scanlan Company
