OUR STORY
The father taught the trade. The son taught it to keep files.
Mike Delaney spent the 1980s roofing for other Columbus companies, and in 1990 he started his own small repair outfit in Clintonville, working out of a rented garage bay off Indianola Avenue. His operation ran on paper: handwritten estimates, a wall calendar, and referrals that traveled by kitchen-table recommendation through Worthington and the north side. He built the business on the jobs bigger companies waved off, the single leak, the one failed flashing, the boot that took out a bathroom ceiling, and on a rule he treated as the whole business plan: repair the roof until repairing it stops making sense, then tell the homeowner the truth about that, even when the truth is the smaller sale postponed and the bigger one is not yours to push.
His son Ryan did the company's labor before he did its thinking. Ground crew at fifteen, shingles carried up ladders through Columbus Julys, full time on the crew in 2009. What he learned up there was the diagnostic half of the trade: water enters at one place, travels along wood, and accuses another place entirely, and the roofer's real skill is reading that journey backward. In 2016, with his father's knees done with ladders, Ryan took over. The crew stayed small. The rule stayed word for word. Everything else got rebuilt: scheduling moved online, and every inspection took on the discipline the paper era never could: the water's path traced back to its entry point and explained to the homeowner before any price is discussed.
In 2017 the company took the name it carries now, Olentangy Roofing, for the river that runs through the middle of its map, from Delaware down past the Ohio State campus to the Scioto confluence where Columbus began. Mike still comes in for coffee and for the leak cases that make the office go quiet. He hears the traced paths now instead of climbing to look, and he has been heard to admit, at least twice, that a good trace beats a bad knee.
Tessa Alvarez joined in 2019 and runs the office: schedule, callbacks, and the order of the day. Three people, one metro, thirty six years of one family's opinions about roofs.
What we run on
Evidence over adjectives
Old, worn, and damaged are claims. A traced entry point at your valley, your boot, your north slope, named and explained, is a fact you can weigh yourself. This company traces first and describes second, because a homeowner holding the findings does not need to take anyone's word for the size of a problem.
The founder's rule, unamended
Repair until it stops making sense. Not repair until a quota is met, not replace because replacement is tidier to sell. When the day comes that repair stops making sense on your roof, you will hear it from a company whose living has come from repairs, and you will see why in the findings.
A roof is a history, not a visit
Every roof has a story worth getting straight: when it went on, where the water has been, what was done about it. Roofs live for decades and homeowners stay for years; the company memory should be at least as long as both.
One metro, two generations deep
The Delaneys have roofed within the same map since 1990, which means the crew has watched whole suburbs be built, age, and start leaking on schedule. That long view is worth something specific: knowing that your street's roofs were installed in one summer, by one builder, is knowing what your roof is about to do before it does it.
