NORTHEAST WISCONSIN – For 15 years, Nasi Roofing, LLC – an Appleton-based commercial contractor has installed “The World’s Best Roof©” (according to roof manufacturer Duro-Last) atop businesses, schools, churches, apartment complexes, hospitals and government buildings alike across Wisconsin and the Upper Peninsula (UP) of Michigan.
Owned and operated by wife and husband Tess and Todd Nasi, Nasi Roofing was founded in 2010 when the couple took over the roofing division of Todd’s father’s construction company, Wayne Nasi Construction.
“It was a seamless transition,” Todd said. “When the company restructured in 2010 and Nasi Roofing was formed, it wasn’t just about stepping into a thriving sector – it was about carrying forward the work I had been deeply invested in for years.”
Prior to the restructuring of Wayne Nasi Construction, Todd said he had dedicated his entire post-college career to bolstering the roofing division of his father’s business.
“Early in my career, I knew I had a passion for the industry, which is why, after graduating college, I took the lead in running the roofing operations at Wayne Nasi Construction,” he said. “Over the years, I dedicated myself to growing the division, building relationships and providing quality roofing solutions.”
Statewide longevity
When the couple took over Wayne Nasi Construction’s roofing division, Tess said all company operations were based in Wisconsin’s north central region.
“When we took over the roofing division of the company, everything was based in Hurley, but Todd and I lived in Minocqua,” she said. “We opened our office in Minocqua so we could work from that area.”
Years after establishing the Nasi Roofing Minocqua office – “we were in Minocqua for 12 years” – Tess said she and Todd decided to move again, this time to Wisconsin’s northeast region.
“My husband and I moved down here – it’ll be three years now in July,” she said. “We had always wanted to expand our business to the Appleton area, so we opened the office here in Appleton, but we (still) have offices in Hurley and Minocqua.”
The headquarters of the business, Tess said, follows her and Todd.
“(Appleton) is definitely the headquarters, because this is where Todd and I are,” she said. “So I guess the headquarters are always where we (are).”
Tess said Todd has racked up nearly 40 decades of roofing industry experience.
“My husband has actually been installing Duro-Last roofs since he was in college,” she said. “His father was one of the very first roofing contractors for Duro-Last when it started. So, Todd has known this system inside and out since the late ’80s, and, basically, it’s all he really loves to do.”
According to its website (duro-last.com), Duro-Last manufactures The World’s Best Roof using a factory-controlled, custom prefabrication process that Todd said results in “precision (and) reduces on-site labor and installation errors – making the process faster and less disruptive.”
“As for the claim of being The World’s Best Roof, Duro-Last backs this up with its extensive warranties, proven performance over decades and billions of square feet installed across various industries,” he said. “The company emphasizes its Edge-to-Edge & Deck-to-Sky approach, which ensures comprehensive protection for buildings.”
Todd said Duro-Last roofs are highly resistant to leaks and, according to Nasi Roofing’s website (nasiroofing.com), “up to 85% of the seams” are prefabricated prior to installation.
“The prefabricated seams eliminate many of the vulnerabilities found in traditional roofing systems,” he said.
Furthermore, Todd said Duro-Last roofs are designed to resist punctures, chemicals, grease, high winds and fires.
“(They) also withstand extreme temperatures, ensuring long-term performance,” he said. “The white Duro-Last membrane (also) has one of the highest retained reflectivity ratings among single-ply membranes – (which helps) to lower cooling costs.”
Industry challenges
As compared to the residential roofing industry, Todd said the practice of installing commercial roofs varies greatly.
“Commercial roofing projects often involve massive square footage, which requires careful coordination of materials, labor and scheduling,” he said. “Unlike residential roofing, where crews can complete a job in a day or two, commercial projects demand weeks or months.”
The lengthier timelines, Todd said, also makes installing commercial roofs in the Midwest especially challenging due to unpredictable weather.
“Harsh winters and rainy seasons can delay commercial roofing projects, unlike residential roofs – which can be installed quickly between weather shifts,” he said. “Commercial roofs require longer dry periods.”
The level of industry experience and expertise required to install commercial roofs, Todd said, is also much greater than that of residential roofers.
“Commercial roofs often involve flat or low-slope designs that require specialized materials like TPO, PVC and EPDM,” he said. “These materials demand expert installation techniques – like heat welding and seam sealing.”
Todd also said commercial roofing projects often face tight budgets and timelines, as well as skilled labor shortages.
However, with every downfall, Todd said there are many benefits to installing commercial roofs – like longevity.
“Commercial roofing systems are designed for long-term performance and often last 20-40 years, compared to 15-30 years for residential roofs,” he said.
Because he’s been in the industry for so long, Tess said there are roofs Todd has installed that are now decades old.
“He’s got roofs that have been out there for 35 years,” she said.
Commercial roofs, Todd said, also allow for more customization and functionality.
“They allow for things like rooftop HVAC systems, solar panel installations and even green roofing options,” he said. “These features optimize space utilization and increase a building’s efficiency.”
Also, because of the materials used to manufacture commercial roofs, Todd said they typically require minimal maintenance and repair following installation.
“Commercial roofing materials are engineered for durability,” he said.
Competition, accolades
Tess said Nasi Roofing is not the only Duro-Last contractor in the State of Wisconsin.
“There’s 60 that are signed up (as contractors) and about 20 that we actively compete against,” she said.
Though the competition is fierce, Tess said Nasi Roofing has been ranked the No. 1 Duro-Last contractor in the state for 10 years.
This year, Duro-Last announced that “in recognition of outstanding achievement in quality workmanship, customer satisfaction and 2024 sales excellence,” Nasi Roofing was presented with the Eagle Award – “which honors contractors achieving more than $2.5 million in sales” – at its annual National Sales Seminar in San Antonio, Texas.
“We believe in the company, and we believe in the material, so it’s kind of a no-brainer,” Tess said. “You do one thing and do it well, is kind of how we’ve always looked at it – though now that we’re down here (in Appleton), we are actually going to be expanding into other products.”
Though they truly stand behind the Duro-Last brand, Tess said in order to maintain its competitive edge, Nasi Roofing is beginning to open itself up to more brands.
“We basically need to keep up with the changing times,” she said. “There’s a lot of times that a PVC look (for a roof) isn’t spec’d in a bid, so we can’t bid on it. So we’ve decided that if we’re going to continue to bid on these jobs and be a player in the market, we have to expand.”
One of the new brands Tess said Nasi Roofing is expanding into is MuleHide – which, according to its website (mulehide.com), is a company made up of commercial roofing experts who are passionate about the industry and serving its people.
With a statewide territory that also stretches up into the U.P., Tess said there’s “no job too big or small” for Nasi Roofing.
“We just did three small post offices throughout northern Wisconsin,” she said. “Those are going to be run of the mill – probably a one-day project. Then another project that we’re working on is a very large apartment complex in Madison – Signature Point Apartments. “(We’ve been working on those roofs) for more than a year, and we’re still not done, because they’re (currently) building them. So we work on (the roofs) as they build (the apartments).”
The next 15 years
Because of their familial connection to Wayne Nasi Construction, and his involvement in its roofing division, Todd said it only made sense for him and Tess to take it over that side of things when the company restructured.
“It made sense for Tess and I to take the lead in shaping its future,” he said. “It was a natural progression, not just an opportunity.”
With his heart and his career invested in commercial roofing, Todd said it was easy for them to see the viability of a stand-alone roofing company.
“We saw the potential to take Nasi Roofing to the next level,” he said, “and we’ve worked hard to make that vision a reality.”
