Architects and builders

Your details, drawn back to you before we form them.

We work from your set. Every valley, ridge, eave and copper element comes back to you as a shop drawing before it is formed, and where our detail differs from yours we say why.

Samples from the lot

Slate samples come from the lot we will install, not a showroom board, so the color you approve is the color you get.

Schedule

Quarry and kiln lead times are on the schedule from the first meeting, and the framing review with your engineer happens before anything is ordered.

The program

Most of a slate roof happens before anyone climbs a ladder.

  1. Phase 1 · Weeks 1 to 3

    Study and drawings

    We measure every plane, draw the roof and its details, and price it line by line.

  2. Phase 2 · Weeks 3 to 16

    Quarry or kiln order

    Slate is ordered by lot so the color matches; clay is fired to order. We inspect samples from the run.

  3. Phase 3 · Before tear-off

    Framing review

    Slate and clay weigh three to five times a shingle roof. An engineer confirms the framing; we coordinate it.

  4. Phase 4 · On site

    Installation

    One plane at a time, dried in every night. Copper is formed on site to fit.

  5. Phase 5 · Closeout

    Roof record and attic stock

    A bound record of quarry, lot and details, and a crate of matched spare slates or tiles left in the attic.

  1. CENTER CRIMP16 OZ COPPEROPEN 5 INDETAIL 1 · SAMPLE

    I

    Open copper valley

    Slate stops short of the center, so water runs on copper, not under stone. The crimp breaks the flow from one slope crossing to the other.

  2. COPPER NAILHEADLAP 3 INDETAIL 2 · SAMPLE

    II

    Slate courses and copper nails

    Each slate covers the joint below and laps the course two below by the headlap. Two copper nails per slate, set so the slate hangs, not pinned tight.

  3. STANDING SEAMCLEATED SADDLEDETAIL 3 · SAMPLE

    III

    Copper ridge saddle

    A formed copper saddle over the last course, locked into a cleat, with a standing seam on top that sheds water both ways.

  4. HALF-ROUND, FORGED HANGERDOUBLED STARTERDETAIL 4 · SAMPLE

    IV

    Eave with a half-round gutter

    A doubled starter course at the eave, a copper drip, and a half-round gutter on forged hangers fixed to each rafter tail.

Private roof study
