Derek Mrocek, the owner of Mrocek & Co., a family-run roofing and exterior company serving Washington County, PA, and beyond.

I started my company in 2024, but I’ve been in the roofing industry for nearly a decade. After years of installing Owens Corning shingles and mastering proper installation techniques, I knew it was time to branch out and offer full-service exterior solutions, including, Gutters (Custom, Leaf Guards, and More!), Soffit & Fascia, Siding, Commercial Rubber & Metal Roofing.

Beyond roofing, I’ve spent my career as an inspector in the oil & gas industry, specializing in coatings and pipeline work. That level of precision and attention to detail is exactly what I bring to every roofing and exterior project we take on.

At Mrocek & Co., we combine big-company expertise with small-business care. We know insurance claims, proper installation specs, and warranties inside and out, ensuring that every project is done right the first time.

Let’s Talk! Whether you need a roof replacement, new gutters, or siding, I’d love to help.
