NIR founder writes book on commercial roof care

HUNTLEY – Building owners are wasting hundreds of thousands of dollars in overhead – the roofs over their heads.

Timothy K. Lynn, founder and chairman of National International Roofing Corp., 11317 Smith Drive, Huntley, wants to fix that.

Lynn has has authored his first book,“The NIR Difference,” to educate building owners, property managers and facility directors the proper way to care for roofs.

“Commercial roofs can cost hundreds of thousands of dollars,” Lynn said. “Most people do the broke-fix method. I pioneered service agreements in the commercial roofing industry.”

The book describes the roofing industry, past and present, and shows how National International Roofing helps building owners maintain their investment.

Lynn said most commercial roofs are replaced 30 percent too soon.

Lynn writes NIR has proven proper care of a roof system will result in a reduction of leak occurrences and more importantly, a larger return on investment.

“The NIR Difference” believes having the same properly trained professional inspecting and repairing minor issues on the roof on a regularly scheduled basis produces the best results.

“An assigned Certified Roof Care Specialist has the tools, equipment and professional knowledge to effectively care for your roof,” Lynn said. “Your roof is money, so protect it.”

Lynn, who said his company is 80 percent service and 20 percent replacement, recommends a roof under 10 years old be inspected twice a year; over 10 years old four times a year.

Data going back about 25 years show that a NIR RoofTop Maintenance Service Agreement reduces annual roof spending by 20 percent, increases the roof life up to 12 additional years (average roof life is 17.5 years), mitigates leak occurrences by 72 percent, prevents premature roof replacement, and provides accurate budgeting for future roofing needs

Service agreements run about $1,250 annually. Local NIR customers include Centegra Health System buildings in McHenry County and Sears headquarters in Hoffman Estates.

Lynn founded National International Roofing in 1980. The company employs about 50 people.

His daughter, Tana Dvorak, is NIR president and CEO. Her husband, Scott Dvorak, is vice president and chief operating officer.

Lynn said NIR services roofs in Illinois, Wisconsin and Indiana. “Our goal is to be in all 50 states in the next five years. We want to be the Roto-Rooter or ServiceMaster of the roofing industry.”

The book currently is available in paperback at and   

Lynn said response to the book has been strong. “One hundred people bought it right away,” he said.
