Main Street Capital Corporation completed a $20 million first‑lien, senior secured term debt investment in Chamberlin Holding LLC, a specialty roofing and waterproofing contractor headquartered in Houston, Texas. The financing is intended to fund Chamberlin’s acquisition of a commercial roofing contractor in the southeastern United States, expanding the company’s geographic footprint.
The follow‑on comes five years after Main Street’s initial $33 million investment in February 2018, which included debt, equity, and an undrawn credit facility. The new financing deepens Main Street’s partnership and signals confidence in Chamberlin’s growth strategy.
Chamberlin, founded in 1897, has built a reputation for high‑quality roofing and waterproofing services across the Southwest. The southeastern acquisition will broaden its reach, potentially increasing revenue streams and achieving economies of scale in procurement and labor.
Main Street’s broader strategy focuses on providing customized, long‑term debt and equity solutions to lower‑middle‑market companies. The $20 million debt aligns with that approach, offering Chamberlin a low‑cost capital structure while preserving Main Street’s credit exposure.
CEO Dwayne L. Hyzak said the investment “reinforces our commitment to supporting portfolio companies that demonstrate strong operational performance and growth potential.” He added that the partnership will help Chamberlin accelerate its expansion plans and deliver value to investors.
Analysts view Main Street’s portfolio as diversified and resilient, with a consensus rating of “Hold” and modest upside expectations. The new investment is expected to strengthen the firm’s asset base and support future deal flow.
