Project Planner / Residential Division Manager

John Graham heads the residential division for Williams American Construction, Inc. John knows what it takes to have a quality roof installed on your home or business.

John J. Reidler
Operations Manager

As operations manager for Williams American Construction, Inc. it is my responsibility to assure our clients of the best roofing installation available.

As a cub roofer I spent years installing roof systems and moving up the ranks from laborer to foreman and then superintendent. I bring an abundance of roof knowledge to our company and get involved with many facets of the operations including roof designs with our project planners.  

As Henry Ford, the innovative automobile manufacturer said “if you think you can or if you think you can’t, you are correct”. At Williams American we know we can and we do.

We are able to offer our clients the best value for their roofing budgets. Designing roof systems includes taking into account the building use, projected length of stay and energy needs. Installing “energy efficient” roof systems is now a huge consideration of our building owners. I have been involved in LEED (Leadership in Environmental, Energy Design) for several years now and know that if we can offset the high cost of energy usage through our roof system designs, we have a satisfied owner.
