Strand Equity-backed Stonegrove Roofing Partners welcomes O’Donnell Roofing, adding a century-old Main Line roofer to its Pennsylvania footprint

Stonegrove Roofing Partners, the New York residential roofing platform backed by family office Strand Equity, has welcomed O’Donnell Roofing Co., a Havertown, Pennsylvania roofer that has served homes and businesses on Philadelphia’s Main Line since 1924, into its network. O’Donnell announced the partnership on its own site, and Stonegrove welcomed the company on LinkedIn. Terms were not disclosed.

The asset.

Founded by C.A. O’Donnell, the company has been family-owned and operated for four generations. It installs, replaces, and repairs residential and commercial roofs, adds windows and skylights, and works from Havertown, Berwyn, and Upper Darby, with a service area that now reaches into New Jersey and Delaware. Stonegrove credits it with a 100-plus person year-round crew and manufacturer credentials from CertainTeed, GAF, and VELUX, among others. Kevin O’Donnell, the fourth-generation leader, will remain an owner and chief executive, and the company keeps its name. “After more than 100 years in business, we have an incredible responsibility to protect what generations before us have built,” he said.

The platform.

Stonegrove describes itself as a collective of residential roofing brands that keeps each partner’s brand, leadership, and team in place, then layers on shared resources — in O’Donnell’s telling, benefits, recruiting, technology, and purchasing — rather than folding partners into a single name. Strand Equity lists Stonegrove Roofing among its active services investments. O’Donnell is one of 16 brands on Stonegrove’s partners page and its third in Pennsylvania, joining McClellands Contracting and Roofing in Oakdale and The Exterior Company in Lancaster.

Filling in a state, not planting a flag.

The structural point is density. With western Pennsylvania and Lancaster already covered, O’Donnell gives Stonegrove the Philadelphia suburbs and a reach into New Jersey and Delaware, through a brand with a century of local referrals rather than one it would have to build — and a commercial roofing book alongside a platform that leads with residential.

What it means.

For owners of multigenerational roofing companies weighing succession, a keep-the-brand buyer is still adding partners, and still leaving the family name on the trucks and the family in the corner office. A long-tenured brand with a deep referral base, documented manufacturer credentials, and a leader willing to stay on is the profile that fits, and owners in states where Stonegrove already has a partner are the more natural next conversations than those in markets it has yet to enter.
