Experienced Slate & Shingle Installer (Hiring Immediately)

GSM Roofing contributed to the National Slate Association's installation manual. Our lead slater is Master Pro Certified. We are looking for another experienced slater who can work to that standard.

We have been doing slate work since 1946. The portfolio is real slate on real buildings: the home of President James Buchanan at Wheatland in Lancaster, the Maytown Reformed United Church of Christ, the 2026 Vermont Gray restoration at St. Matthew Roman Catholic Church in Tyrone (a National Register property listed since 1993), and the 35,450-piece synthetic slate installation at Penn State's Nittany Lion Inn.

If you have cut, fit, and laid natural slate. If you can match a replacement on a weathered roof so it disappears into the field. If you know what proper head lap looks like, what silicone caulk on a slate joint actually means, and why your last employer kept handing you the historic jobs. Keep reading.

If your experience is a few years of asphalt shingle and you would like to learn slate, this is not that role. We have plenty of openings where you can grow into the trade. This one is for someone who is already there.

The Work

You will install, repair, and restore natural slate, synthetic slate, and architectural shingle roofing on residential, commercial, institutional, and historic properties across Pennsylvania, New Jersey, Delaware, and Maryland. You will work alongside our specialty metals team, the people who fabricate the copper flashings, ridge caps, and snow guards in-house rather than subbing them out.

Some weeks the work is straightforward: a tear-off and reinstall on a steep-pitch shingle job. Other weeks you are matching slate on a church where the original installer is long gone and the quarry has been closed for decades. You will figure it out. That is what we are hiring you to do.

Why GSM

We have been here since 1946. Over 100 of our employees are in our 25-Year Club, with us a quarter century or more. That is not a marketing statistic. It is a description of the room you would be working in.

Our lead slater is Master Pro Certified. The new hire joins the crew as a peer.
