O’Donnell Roofing Co. Joins Stonegrove Roofing Partners Platform

What happened

O’Donnell Roofing Co., a roofing contractor based in Havertown, Pennsylvania, announced on November 9, 2026, that it had entered a strategic partnership with Stonegrove Roofing Partners (SRP). Kevin O’Donnell will remain an owner and chief executive officer, leading the company’s employees, operations, and strategic direction. The company will keep operating under the O’Donnell name. Through Stonegrove, it gains access to expanded employee benefits, recruiting support, and professional development, along with help on technology, business systems, and purchasing. Neither company disclosed financial terms or what stake, if any, changed hands.

The company

Clement Aloysius O’Donnell Sr. founded C. A. O’Donnell Roofing and Heating in 1924, with a sheet metal fabrication shop at 56th Street and Lansdowne Avenue in West Philadelphia. His son, Clement Jr., took over in 1953 and carried the business into the Philadelphia suburbs. Clement Jr.’s son, Laurence “Larry” O’Donnell, renamed and incorporated the company as O’Donnell Roofing Co. in 1980. Larry added commercial roofing and historic restoration, with projects at Longwood Gardens and the Merion train station. He took the company into solar in 2006. Larry stepped down as president in 2017 and passed the business to Kevin O’Donnell, the family’s fourth generation in the business.

Today the company does residential roofing, siding, windows, gutters, and solar, plus commercial roofing and repair, for homeowners and businesses in Pennsylvania, New Jersey, and Delaware. Its home ground is the Main Line and Delaware, Montgomery, Chester, and Bucks counties. On commercial work it holds approved applicator status with manufacturers including GAF, Carlisle, and Duro-Last. The company bought its first property in 2018 and opened a satellite office in Berwyn in 2021, which houses its sales team and a showroom. Its family of brands includes O’Donnell Solar, RJ Egan Painting, and Excel Slate & Copper, a slate, copper, and historic-roof specialist working in New Jersey and Pennsylvania.

“After more than 100 years in business, we have an incredible responsibility to protect what generations before us have built,” Kevin O’Donnell said. “This partnership gives us the opportunity to strengthen our foundation, invest in our people, and build an even stronger company for our employees, customers, and the communities we serve.”

The partner

Jonathan Shifke and Pierre Abousleiman founded Stonegrove Roofing Partners. The platform is backed by Strand Equity, which lists Stonegrove Roofing in its investment portfolio. Stonegrove describes itself as a collective of residential roofing brands that keeps each partner’s brand, leadership, and team in place. Behind them it supplies shared services, including HR, marketing, finance, recruiting, technology, and vendor purchasing. Its partner brands run from Golden Group Roofing in Greater Boston to Integrity Roofing & Construction in Poulsbo, Washington.

Stonegrove says its model lets owners “take chips off the table while retaining meaningful ownership and continued upside as the business grows.” It says its process takes 60 to 90 days from a signed letter of intent (LOI) to close.

Stonegrove’s brands around Philadelphia

Stonegrove also has partners in two of the three states O’Donnell serves. The Exterior Company (TEC), founded in 2012 and based in Lancaster, Pennsylvania, does roofing, siding, and gutters across Pennsylvania, Maryland, Connecticut, and New Jersey. National Contractors, an exterior building contractor in Ewing, New Jersey, does low-slope and steep-slope roofing.

What this means for roofing owners

For a family roofing company, taking on a platform partner and handing off leadership are two separate decisions, and this deal made only the first. That matters most to a business where the next generation is still the plan, because the partnership does not have to settle who runs the company after the person running it now.
