Custom Red Copper Flat Lock Cricket in Centerville

This is one of the smallest pieces of work we have ever photographed — and one of the most important. A few square feet of red copper, folded and locked by hand into a diamond-patterned cricket on a waterfront roof in Centerville. Two days of work. And yet this single detail tells you everything about how a roof should be built: because the places nobody looks at are exactly the places where roofs fail — or don't. Over two days, our master tinsmiths hand-formed every panel of this custom flat lock cricket, creating a detail that channels water away from the structure and will keep doing so for decades.

The Most Important Detail You've Never Heard Of

Ask most homeowners what keeps a roof dry, and they will say "the shingles." But water on a roof is patient. It hunts for the places where something interrupts the flow — a chimney, a wall, an intersection of planes. Left alone, water piles up against those interruptions, backs up under the material, and finds its way in. Debris follows water. Ice follows debris. And a leak follows all of it.

A cricket is the answer: a peaked structure built behind an interruption to split the water and send it around, the way a bow wave parts around a boat's prow. It is invisible from the street once the roof is finished, and it is one of the biggest differences between a roof that merely looks right and a roof that is right. On this Centerville home, the cricket received the full treatment — custom-built in red copper, in the flat lock tradition.

Flat Lock: Metalwork From the Old World

Flat lock is not a product. It is a technique, and an old one: individual metal panels, each edge folded, each fold locked into its neighbor so the field becomes a continuous, flexible skin. The result is the diamond pattern you see in the photo — a pattern that is not decorative at all, but the visible record of every seam doing its job.

Why build a cricket this way instead of bending one large sheet? Because small locked panels conform to complex peaks without stress cracks, move with thermal expansion instead of fighting it, and can be repaired panel by panel generations from now. It is slower. It is harder. It is also the reason hundred-year-old copper roofs still stand. Our tinsmiths folded, seamed, and locked every panel of this cricket by hand — the same way it was done a century ago, with modern underlayment beneath it.

Two Days, One Diamond

Day one was measurement and formation: patterning the peak, folding each copper panel on the bench, test-fitting on the roof, and adjusting until the geometry ran true. Day two was locking and integration: seaming panel to panel, tying the cricket into the surrounding flashing, and lapping it correctly over the premium synthetic underlayment so water always moves from higher to lower, never sideways into the deck.

Look closely at the photo and you will even see the tinsmith's shadow at the edge of the frame — a fitting signature for work this personal. When the shingle field is completed around it, most visitors will never know the cricket is there. That is precisely the point.

Waterfront Rules: Built for Salt and Decades

The pond glinting behind the ridge in this photo is a reminder of where this roof lives. Centerville's waterfront air carries salt, and salt is merciless to shortcuts. Copper is the shore's own answer: it shrugs off corrosion, seals tight, and weathers into a patina that protects it further. Combined with a premium synthetic underlayment — the same disciplined base we bring to every asphalt roofing installation — the detail becomes a system, and the system becomes decades of dry ceilings.
