Mrocek & Co. is a family-run roofing and exterior company proudly serving Washington County, Pennsylvania and the greater Pittsburgh region. Founded by Derek Mrocek, the company is built on 20+ years of hands-on roofing and construction experience, backed by a career rooted in precision inspection and quality control.

Our expertise extends far beyond a single roofing product. Mrocek & Co. has extensive experience working with a full range of residential and commercial roofing systems, including architectural shingles, commercial rubber roofing (EPDM/TPO), standing seam and metal roofing, and natural slate. Every system we install is completed strictly in accordance with manufacturer specifications and industry best practices — because proper installation is what determines whether a roof lasts 5 years or 30.

What truly sets Mrocek & Co. apart is our field team. Our journeyman crews each bring 15+ years of real-world experience serving the greater Pittsburgh area. These are seasoned professionals who understand the nuances of Western Pennsylvania weather, ventilation requirements, flashing details, and long-term roof performance. Simply put: we do not send inexperienced labor onto your home.

In addition to roofing, Derek’s background in the oil and gas inspection sector — specializing in coatings and pipeline work — brings an elevated level of scrutiny and attention to detail to every exterior project we perform.

At Mrocek & Co., clients receive big-company expertise with small-business accountability. From insurance claim support to code-compliant installation and warranty protection, every project is executed with precision, transparency, and pride.

Built right. Installed right. Done right the first time.
