Nico Del Monaco inherited a roofing business already at the top of its market—now he's focused on keeping it there.

Del Monaco was appointed president of Owens Corning's Roofing business in 2025, succeeding Gunner Smith. He came to the role with 25 years of experience at the company, most recently leading the Insulation division, where he expanded capacity across multiple product lines and strengthened the business's market position. Before that, he ran Owens Corning's European operations, overseeing both insulation and nonwovens products—experience that gave him a cross-divisional perspective on the company's building products portfolio.

Now leading roofing operations, Del Monaco is pursuing a dual strategy: expanding manufacturing capacity in high-growth regions while equipping contractors with digital tools that streamline operations. That includes the Prattville, Ala., shingle plant—a strategic expansion into the Southeast, the nation's largest asphalt shingle market—and continued investment in the Owens Corning Tech Stack, the company's integrated digital platform for contractors.

In this Q&A, Del Monaco discusses his first-year priorities and how he's positioning the roofing business for sustained competitive advantage.

We continue to invest in our business, product development, and the services and partnerships that contractors need to grow their businesses. I’m really excited to meet more of our customers and learn how we can continue to innovate to help them win in a competitive marketplace.

"Over the next 3–5 years, we envision deeper, more digitally enabled partnerships with contractors and distributors. This means … tools like the Owens Corning Tech Stack will make interactions more seamless—helping contractors manage leads, visualize projects, and track performance in real time.” — Nico Del Monaco

RC: Drawing from your operations background, what are your immediate priorities for improving roofing's manufacturing footprint?

NDM: In manufacturing, our priorities have been unlocking efficiencies and creating network flexibility through ongoing debottlenecking efforts and strategic investment to service our growing contractor network. Last year, we announced our strategic investment in Prattville, Alabama, where we are building a new shingle plant in the Southeast, the largest asphalt shingle region in the country. I also want to commend and thank our teams for their collaboration and unconditional commitment to safety as they produce the high-quality products that our customers rely on.

RC: When will contractors begin to see the benefit of Prattville shingle plant?

NDM: Construction on this 250,000-square-foot plant will start early this year. The plant will feature leading technology and have the capacity to produce approximately 6 million squares of laminate shingles annually, enhancing service across our network.

RC: How do you plan to leverage technology and automation to enhance production efficiency?

NDM: Digital solutions will continue play a transformative role in the roofing business by empowering contractors to work smarter, faster, and more efficiently.

NDM: Continued product innovation is at the core of Owens Corning’s strategy to meet evolving customer needs. We are committed to developing roofing solutions that deliver superior performance, durability, and aesthetics, while addressing key market trends such as sustainability and energy efficiency.

RC: How do you expect OC’s relationships with contractors and distributors to evolve over the next few years?

NDM: Over the next 3–5 years, we envision deeper, more digitally enabled partnerships with contractors and distributors. This means: Digital Integration: Tools like the Owens Corning Tech Stack will make interactions more seamless—helping contractors manage leads, visualize projects, and track performance in real time.
