Both — and we’re intentional about how we use each. Our in-house team handles smaller repairs and serves as our quality control backbone on every project, making sure installations meet Owens Corning standards so we can back your roof with the Owens Corning Preferred Warranty. For specialized work, we partner with subcontractors who are genuinely exceptional at their craft — people who have spent their careers mastering what they do. We don’t sub work out to cut corners. We do it because the right partner does certain things better than anyone, and our homeowners deserve that level of quality across the board.
