Gut R Dun Exteriors was founded on an unapologetic Midwestern standard: treat every customer's home with the honesty, structural precision, and longevity we demand for our own families.
Founder & Managing Director
Dayton Native & Industry LeaderAfter years of witnessing homeowners across Montgomery, Warren, and Greene counties fall victim to fly-by-night storm-chasing sales operations and cut-rate subcontractors, Derek Jacobs launched Gut R Dun Exteriors with a single foundational standard: permanence.
We invested in our own certified in-house crews, established our permanent headquarters on Byers Road in Miamisburg, and earned elite factory credentials with North America's premier exterior manufacturers, including Owens Corning, GAF, and James Hardie.
"A roof isn't just shingles and underlayment; it's everything and everyone you care about underneath it. When our crews arrive at your home, we don't pack up until it's done right."
— Derek Jacobs, FounderEvery Gut R Dun exterior installation is engineered according to rigid local quality benchmarks.
We never compromise with builder-grade components. Only industry-best synthetic ice & water barriers, Class 4 impact shingles, and heavy-gauge seamless gutters.
Our installers undergo rigorous factory training. Every valley, step-flashing junction, and vent boot is triple-sealed for Midwest freeze-thaw extremes.
No hidden line items or surprise price spikes. What we quote in our itemized scope is exactly what you pay—guaranteed in writing for 30 days.
Backed by 50-year non-prorated manufacturer coverage plus Gut R Dun's direct workmanship warranty for total peace of mind.
Whether you need a comprehensive drone roof inspection, surgical micro-mesh guards, or a full exterior restoration, our Dayton team is ready.
