Mantorville is the county seat of Dodge County, a town of about 1,100 sitting on the Zumbro River roughly 18 miles west of Rochester. The whole downtown district is on the National Register of Historic Places, which means a good share of Mantorville's homes are older builds with the kind of roof lines and aging shingles that need a roofer who knows what's underneath. Older homes near Riverside Park and newer builds out along Highway 57 toward Kasson catch the same Dodge County hailstorms. Gray Duck Roofing is the closest credentialed local roofer; we're a short drive up US-14, not a Twin Cities crew making the trip down after a storm.
Mantorville sits in the same Dodge County hail and wind corridor as Kasson, Dodge Center, and Rochester. Spring storms roll in off the prairie, winter loads the roof with snow and ice, and the freeze-thaw cycle works on every seam and shingle for months. Older homes in the historic district add their own wrinkle, with steeper pitches and decades-old decking that deserve a careful eye. Gray Duck Roofing covers the full exterior so Mantorville homeowners have one contractor to call.

Real reviews from real homeowners in our community.
"We just had our roof replaced by Gray Duck Roofing, and it was a fantastic experience from start to finish. I first met Ryan last year when we were just exploring options, and he stuck with us through a long decision-making process—never pushy, always professional, and incredibly patient. "
"Tremendous service and excellent communication. We’ve had plenty of work done on our house over the years and have never had a contractor be so on top of things. Timelines, budgets, team, quality materials. Can’t say enough good things about Ryan’s group. 10/10 recommend."
"Ryan and his crew did a great job on my new roof! Ryan explained everything, was helpful with picking out colors and was able to get me on the schedule quickly. The crew was friendly, did the job fast and did a nice job cleaning everything up, before leaving. Highly recommend!"
"Highly recommend Ryan and his crew! Great communication and very personable. Showed up on time and work completed very fast but thoroughly from inspection to completion. Couldn't have asked for a better experience for a very frustrating and stressful situation."

""Ryan and his crew were fantastic! If I could give them 10 stars, I would. They finished the job quickly and the cleanup was so thorough it was like they were never even here. Ryan worked with our busy schedules and helped us make all of our selections online, it was such convenient and easy process. We could not be happier with our new roof!
"Ryan and his crews did an amazing job with everything from handling the insurance right down to the final details. I would highly recommend them."
"Great communication, open to our thoughts and concerns. The house has a large roof as there is a 3 car attached garage. In one day they took off 2 layers, repaired a few bad areas and covered vents no longer used, and finished shingling."
"Very promp and timely service! Knowledgeable and courteous. Our problem was just a clogged gutter and Ryan took care of it quickly. Would definitely recommend Gray Duck Roofing."

Answers to our most popular questions.
Most Mantorville roof replacements land between $8,000 and $16,000. The final number depends on roof size and pitch, the shingle line you choose, and whether we find decking or flashing damage when the old roof comes off, which is more common on the older homes in the historic district. Every estimate breaks the cost down component by component so nothing is buried in a single line item.
Mantorville is about 25 minutes from our Rochester shop, just north of Kasson on Highway 57. After a major hail event we can usually have a free inspection scheduled within a few days. Storm-week call volume stretches the schedule, but Dodge County homeowners are inside our regular service area, so you don't get bumped.
Yes. We photograph the damage, write up the scope of repair, meet your insurance adjuster on-site, and stay in the conversation until the claim is approved. Hail claims across Dodge and Olmsted counties are a core part of what we do, and we know what each carrier needs to see.
Owens Corning Duration shingles are our default. The 130 mph wind rating handles the open-field gusts that come across the prairie west of Rochester, and the cold-weather flex makes them a strong choice for Minnesota winters. We walk through other Owens Corning lines on request, including options suited to older or steeper historic-district roofs.
Yes. The City of Mantorville requires a building permit for roof replacement. Gray Duck Roofing pulls the permit on your behalf and schedules the required inspection, so the project stays code-compliant and you stay out of the paperwork.
