In pre-qualifying the bidders for this $535,000.00 project, I focused on well-established local firms with an in-house sheet metal shop and a strong base of repeat clients. Knickerbocker had excellent references and a wide range of experience in built-up coal tar systems and Sarnafil PVC membranes.
Knickerbocker provided a competitive price and the work was performed between July and October, with three different crews that specialized in built-up roofing, Sarnafil membranes and sheet metal work. It was apparent that each crew was supervised by a well trained and experienced foreman who had pride in the quality of the finished product. The training and team spirit of each member of the crews was apparent as they worked quickly and efficiently to produce a good product.
Re-roofing a fully occupied building always created logistical problems and complaints about “inconveniences”. Your workers were always courteous and accommodating in solving these problems.
In particular, I appreciated the willingness of your sheet metal fabricators and installers to work with me in designing a variety of specialized shapes to solve the original detailing problems.
In the three months since the job was completed, we have experienced several rain storms with blowing wind, but no leaks in the new roofing systems. Your company’s attention to detail was instrumental in finally ending a twenty (20) year history of roofing problems at this project.
Thank you for a job well done.
