NEW GAS APPLIANCE PIPING

New RTU gas piping for commercial roofs. We size, design, and install Schedule 40 gas mains and branch lines for new rooftop units – laid out clean, properly supported, pressure-tested, and ready for inspection and start-up. Sizes from 1 1/4” - 2” Threaded.

Adding RTU’s? We re-size, re-route, and rebuild existing piping in proper Schedule 40, add isolation valves and supports, clean up hacked-in branches, and bring everything up to code so your new RTUs get the gas volume they actually need — no guessing, no shortcuts.

We strip out tired, crooked, under supported rooftop gas piping and rebuild it as a proper RTU gas run. Clean, straight routing, correct pitch, isolation valves where they should be, unions positioned for service, and supports set to spec so nothing sags, binds, or fights you during maintenance or change-outs. Having roofing done? Need your existing gas pipe removed and re-installed? We can handle it.

Unpainted rooftop gas piping isn’t just ugly — it’s not up to code. We prep, prime, and paint exposed gas lines in proper safety colors, tighten up supports, and tag valves so your RTU piping is protected from the elements and ready for inspection.
