Serving Homeowners and Contractors
With Smarter Metal Roofing & Siding SOlutions
At On-Site Metals, we’re focused on one goal: making roofing and siding projects faster, simpler, and more reliable for homeowners and contractors in Central PA. We manufacture and install standing seam roofing and metal board and batten siding, using advanced rollforming machines to create panels directly at your location. When panels are made on-site, you get a perfect fit, less waste, and no delays waiting for factory orders.
Our Story
Back in 2017, Marlin started working in construction and quickly saw a problem: contractors were driving hours to pick up panels, only to waste time cutting and adjusting them to fit. There weren’t local manufacturers offering high-quality rollforming with offset and preset notching.
We launched On-Site Metals to solve that problem. With mobile, high-tech rollforming equipment, we now bring the manufacturing directly to the job site.
“As an installer myself, I understand the challenges contractors face. By staying connected to the installation side, we can constantly improve our products and processes to save you time and material.”
Why We Do What We Do
We believe that better roofing and siding solutions come from understanding the real-world challenges you face. That’s why our work is centered on serving people — homeowners who want a long-lasting, beautiful roof or siding, and contractors who need accurate, efficient products to keep their projects moving.
