In addition, it was reassuring to see that Roof's quality control plan is personalized for each project — it isn't boilerplate or off the shelf. It reflects what the specific project requirements are. Roof took full responsibility.

I would like to thank you again for the hard work you and your team have put into the successful completion of our Project. Your strong attention to keeping and improving the schedule is the major reason for the timeliness of completion.

Roof's Interactive Solutions provides digital tools to industrial, manufacturing and processing facilities worldwide, including Sim-pro, an Internet-based virtual reality tool for training and evaluating plant operators.
