"My dad started this company on a promise: treat every roof like it's your own family's. That promise hasn't changed."
Real neighbors. Real roofs. Real results. These are unedited reviews from Google.
"After the hail storm in March, Bob Harmon showed up within two hours. He walked my roof himself, explained every issue clearly, and had a crew here by Friday. No pressure, no upselling. My neighbors couldn't believe how fast and clean the job was."
"We've used Harmon Roofing twice — once in 2011 and again this year for a full replacement. Both times: punctual, professional, and priced fairly. The crew cleaned up so well you'd never know they were here. Highly recommend to anyone in Hamilton."
"I was nervous about getting ripped off — I'd heard the horror stories. A friend referred me to Harmon and I cannot express enough how different the experience was. Bob took time to explain my insurance claim, fought for the right coverage, and delivered a perfect roof."

Bob Harmon answers his own phone. When you call Harmon Roofing, you get the person who's been doing this for 30 years — not a salesperson reading from a script.
Every job is completed by our own trained crew. No subcontractors, no strangers on your roof. The same team you meet at the estimate is the team doing the work.
Our quotes are itemized and explained in plain English. We don't hide fees or manufacture urgency. If your roof doesn't need replacing, we'll tell you that too.
Lifetime workmanship warranty on all replacements. If anything we installed leaks, we come back — no charge, no argument. That's been our promise since 1994.
In 1994, my father Gerald Harmon started this company with a single truck, a $3,000 loan, and a belief that Hamilton deserved a roofer they could actually trust. He didn't advertise much — he just showed up on time, did the work right, and let the neighbours talk.
I took over in 2009. The name on the truck changed, but nothing else did. We still use the same crews — some have been with us over 15 years. We still answer the phone ourselves. And we still believe your home deserves the same care we'd give our own.
We've replaced over 2,400 roofs across Hamilton-Wentworth. We've helped families after every major ice storm and wind event to hit the area. And we've never once walked away from a warranty claim.
