Sound Growth Partners Acquires Hydro-Vac Holdings Roof Prep Services

Sound Growth Partners (SGP), a Seattle-based private equity firm, announces the acquisition of Hydro-Vac Holdings, Inc. (RK HydroVac) as of April 1, 2026. The transaction was executed using SGP’s One-Stop Buyout structure, with capital provided by SGP and co-investors. This acquisition adds a market-leading roof preparation services company to SGP’s portfolio, reinforcing its position in the business services and construction sectors.

RK HydroVac, headquartered in Piqua, Ohio, has operated since 1981 as a critical provider of roof preparation services for the repair and replacement of low-slope ballasted roofs across the United States. The company offers specialized dry and wet-vacuum services, ballast removal, pneumatic ballasting, and disposal services, supported by a dedicated fleet of Hydrovac trucks tailored to commercial re-roofing needs.

Founded in 2023, Sound Growth Partners focuses on investing in clear market leaders within the lower middle market, targeting companies with EBITDA between $2 million and $15 million. SGP’s One-Stop Buyout approach provides all necessary capital to close transactions, enabling streamlined acquisitions in niche sectors such as consumer products, business services, distribution, and light manufacturing.

Travis Steele, Partner at SGP, commented, “RK’s 45-year track record and history of operational excellence have positioned the company as an invaluable partner to roofing contractors across the country. We appreciate the opportunity to partner with the RK team and look forward to supporting the company through its next phase of growth.”

The acquisition strategically strengthens SGP’s footprint in the commercial roofing support services market. By integrating RK HydroVac’s specialized service offerings, SGP aims to cross-sell roof preparation services to existing portfolio companies and expand into new commercial roofing contractor segments. The deal also supports geographic expansion, particularly in the Midwest, with potential to extend into adjacent U.S. regions.

Operational synergies are expected through consolidation of back-office functions, optimization of fleet utilization, and bulk procurement of equipment and disposal services. SGP plans to implement advanced fleet management and scheduling systems while enhancing safety and compliance protocols leveraging RK HydroVac’s expertise.

The commercial roofing industry is experiencing consolidation, with niche service providers like RK HydroVac playing a vital role in supporting re-roofing projects. This acquisition positions SGP to capitalize on industry trends favoring operational scale and service differentiation. Competitors may respond with similar consolidation efforts or investments in fleet capabilities.

Financial terms of the deal were not disclosed. The transaction was funded entirely by SGP and its co-investors, consistent with SGP’s capital provision model. No external advisors were publicly reported.

Looking ahead, SGP will focus on integrating RK HydroVac’s operations while maintaining its specialized expertise and customer relationships. Key challenges include aligning corporate cultures and managing fleet logistics without service disruption. Retaining RK HydroVac’s management and technical staff is critical to sustaining operational excellence.

This acquisition marks another step in SGP’s growth strategy to build a portfolio of market-leading companies in specialized service sectors. The firm’s capital and operational support are expected to accelerate RK HydroVac’s growth and enhance its competitive position in the commercial roofing support market.
