02 — The Craft
The shop · Folsom Street, San Francisco
We build likearchitects.Finished like furniture makers.
Meridian is a thirty-one-year-old roofing house. We work from a single shop on Folsom Street with two field crews — eleven journeymen between them — and we take on no more than twenty-four projects in a calendar year.
Every roof is drawn, full-scale, in the shop before it leaves the bench. Every fastener pattern, every flashing detail, every seam length is set on paper, mocked up in metal, and approved by the architect of record before we touch the building.
We are a Master Elite installer for GAF and a SELECT ShingleMaster for CertainTeed — the top two percent of the trade nationwide. Our workmanship warranty runs fifty years. Most of our work never needs it.
