What Interstate Roofing does
Interstate Roofing (legal entity Interstate Roofing & Waterproofing, INC.) is a privately held, family-owned commercial roofing contractor founded in 1968 and headquartered in Onalaska, Wisconsin. The company installs, replaces, and services roofs for businesses, warehouses, industrial facilities, educational institutions, healthcare providers, government buildings, and historical structures across a four-state Upper Midwest footprint (Wisconsin, Minnesota, Illinois, and Iowa). Its core service lines are commercial roofing, historical restoration, wall panel systems (pre-finished steel, aluminum, zinc, stainless steel, copper, and composite materials), and 24/7 emergency leak repair backed by 15–30 year manufacturer's workmanship warranties on low-slope installations. Additional specialties include metal roofing, green (vegetative) roofing, and industrial roofing.
The company reports 75 skilled workers, 350+ completed projects, 57 years of operating history across three generations, and 27 industry awards. Its technology differentiators are rooted in materials breadth and trade expertise rather than software: expertise across metal, membrane, and green roofing substrates; wall panel and rain-screen systems configured for weather protection, fire safety, and resistance to mold/rot; and a dedicated service department with multiple crews available 24/7 for emergency leak dispatch. Underlying workflow tools support estimators who handle client relations, project management, and drafting — not AI-driven automation.
Interstate Roofing operates on a project-based, quote-driven revenue model: customers request estimates through the website or via departmental phone lines (leaks/service, estimates, billing, accounts receivable, etc.), and field crews execute installations or repairs on a regional, fixed-fee basis. Revenue streams include one-time roofing installations and reroofs, historical restoration projects, wall panel installations, and recurring service/warranty work. Pricing is not publicly disclosed and is delivered per quote; no subscription or recurring SaaS-style revenue exists. Leadership transitioned from founder Charlie Kasten (50-year career) to second-generation President Derek Kasten and Vice President Jon Kloehn; the firm remains privately held with no external institutional capital.

Interstate Roofing competitors and assessment
Company assessmentBroad incumbents
- Tecta America: Largest commercial roofing contractor in the United States with national coverage. A direct competitor on large enterprise accounts, but with significantly greater scale, multi-region density, and capital resources that could pressure smaller regional players like Interstate.
- Nations Roof: National commercial roofing contractor with locations across the U.S. Overlapping service offering in commercial installation, reroofing, and repair, with greater geographic reach and a similarly broad customer base in industrial, retail, and institutional segments.
- Roofing Corp of America (RCA): PE-backed national roll-up platform acquiring leading regional commercial and residential roofing contractors. Comparable to Interstate in operational profile but with substantially more capital and an explicit acquisition strategy that could make Interstate a target.
- CentiMark Corporation: National commercial roofing contractor offering installation, repair, and maintenance across the U.S. and Canada. Competes with Interstate for enterprise and industrial accounts, and serves as a potential acquirer of regional contractors.
- Flynn Group: Canada's largest roofing contractor with growing U.S. commercial roofing presence. Competes for large enterprise and industrial accounts and represents the kind of well-capitalized, multi-region incumbent that constrains regional contractor growth.
Direct peers
- Deer Park Roofing: Cincinnati-based commercial and residential roofing contractor serving Ohio, Kentucky, and Indiana. Comparable Midwest regional contractor with similar commercial flat-roof installation, repair, and historical/specialty work — direct competitor for similar enterprise accounts.
- Greenwood Industries: Mid-sized commercial roofing and sheet metal contractor with a strong historical restoration and architectural metal panel practice. Highly comparable to Interstate's mix of commercial roofing, wall panel systems, and historical/architectural specialty work.
- Bone Dry Roofing: Indianapolis-based commercial and residential roofing contractor serving the Midwest with multiple branch locations. Closest geographic and service-line peer to Interstate Roofing, with a similar mix of commercial installation, repair, and multi-state regional coverage.
Regional players
- Baker Roofing Company: Raleigh, NC-based commercial and residential roofing contractor serving the Carolinas and Southeast. Comparable in business model (commercial installation, repair, sheet metal), but operates in a different geography — useful comp for sizing regional commercial roofing peers.
Others
- Tremco Roofing: Major commercial roofing manufacturer and service provider offering installation, maintenance, and warranty programs. Adjacent to Interstate through the roofing value chain — Tremco's warranty/service programs interact directly with contractor-installed projects.
