O'Leary Roofing & Contracting | General Contractors & Roofing in Philadelphia, PA 19135

Philadelphia's humid summers and cold winters can create moisture issues in attics if ventilation and insulation aren't properly balanced. Poor ventilation traps warm, moist air, leading to condensation, mold, and ice dams in winter. We assess your existing roof system to ensure adequate airflow and recommend insulation solutions that manage moisture effectively, protecting your home's structure and improving energy efficiency year-round.

As a full-service general contractor, we manage the entire project from planning to completion. This includes coordinating all necessary trades—like carpenters, electricians, and plumbers—pulling required permits for Philadelphia's specific building codes, sourcing materials, and maintaining a clear timeline and budget. Whether you're updating a single room or undertaking a larger renovation, we handle the details so you don't have to, ensuring a smooth process and a quality finish.

Absolutely. As a single-source contractor offering both roofing and siding services, we can comprehensively address storm damage. This integrated approach means we can inspect the full exterior envelope of your home, provide a coordinated repair plan, and ensure all work is completed to the same high standard. It simplifies the process for you, often resulting in a more seamless repair and a consistent warranty on the materials and labor.
