What Nasi Roofing, Llc does

Nasi Roofing, LLC is a privately held commercial and residential roofing contractor headquartered in Appleton, Wisconsin, founded in 1983 and operating as a regional entity within the Royalty Roofing family of companies. The company specializes in Duro-Last single-ply membrane roofing systems for flat and low-slope commercial roofs, leveraging factory-controlled prefabrication that completes up to 85% of seams off-site to reduce leak risk and shorten installation time. It is a top-3% Duro-Last contractor by volume and an authorized installer across Wisconsin and Michigan, with additional staffed offices in Minocqua and Hurley serving northern Wisconsin. Customer verticals include industrial and manufacturing, retail and office, education and nonprofit, restaurants and franchises, apartments and multi-family, cold storage, and Wisconsin residential homeowners, served through a direct enterprise field-sales motion for commercial work and direct-to-consumer outreach for residential jobs.

The business model is project-based roofing services revenue plus warranty-backed recurring repair and maintenance work. Commercial projects span new installation, full replacement, metal retrofit (Duro-Last membrane installed over existing metal roofs without tear-off), and inspection, with 15- to 30-year Duro-Last material and labor warranties available. Residential revenue comes from Owens Corning architectural shingle installation, repair, and replacement as a Platinum Preferred Contractor, supplemented by add-on services such as gutters, siding, soffit, and fascia. Pricing is quote-based with free estimates, free inspections, and free long-term budgeting, and residential customers can access up to $55,000 in financing through a referral partnership with Contractor Loan PRO (Momnt Technologies). Marketing is multi-channel and regional, combining educational blog content with organic social (Facebook, LinkedIn, Instagram, YouTube) and bottom-of-funnel conversion through free inspection offers and financing.

The company's principal competitive moat is its four-decade authorized relationship with Duro-Last and its sustained Platinum-tier award record, which confers procurement scale, manufacturer-backed warranty strength, and quality assurance inspection on every job. Principal risks include concentration in two regional states (Wisconsin and Michigan), dependence on Duro-Last and Owens Corning as upstream technology and brand suppliers, project-based revenue lumpiness, and limited public disclosure of financial or headcount data.
