Copper & Roof Architecture Case Studies
Copper and roof geometry are where most failures begin — and where the best heritage exteriors distinguish
themselves. These projects show how Heritstone treats copper, valleys, crickets and roof architecture as
one disciplined exterior system, not an accessory to “roofing.”
Case Study 1 — Copper Cricket & Dead Valley Reconstruction
A stone chimney sat directly in the path of converging roof planes, creating a persistent dead valley and
chronic leakage. Multiple sealant and patch attempts had failed.
- Existing patchwork metal and sealants fully removed
- Roof framing locally adjusted to improve drainage pitch
- New copper cricket formed and soldered as one continuous assembly
- Counter-flashings cut and set into chimney masonry reglets
- Adjacent slate fields lifted and reset over proper copper bibs
Result: Dead valley eliminated and water redirected cleanly around the chimney for long-term performance.
Case Study 2 — Full Copper Porch Roof Over Masonry Entry
A primary masonry entry had been capped with a temporary low-slope roof that clashed with the architecture.
The owner wanted a permanent copper solution scaled correctly to the façade.
- Existing membrane and framing removed and redesigned
- New timber framing proportioned to match the stone surround
- Continuous copper pan formed and locked with standing seams
- Integral drip edge and concealed gutter returns fabricated
- Wall flashings stepped into stone joints, not face-sealed
Result: A copper porch roof that reads as original to the masonry entry, not an afterthought.
Case Study 3 — Bay Roof Conversion to Copper & Slate
The bay windows on a stone home had been roofed with short-lived materials. Water had begun to track back
into the wall assembly at the upper transitions.
- Removal of failing coverings and saturated underlayment
- Decking repaired and pitched correctly for copper seams
- Copper pans installed beneath slate in critical tie-in zones
- Slate fields laid to scale with the bay geometry
- Upper wall flashings and head flashings rebuilt in copper
Result: A bay roof language that matches the main slate and copper assembly, with water exiting cleanly.
Case Study 4 — Low-Slope Transition Behind Main Gable
Behind a tall gable, a low-slope roof section had become a chronic leak point where asphalt and pieced-in
metal had been used in place of proper copper detailing.
- Low-slope area reframed where needed for consistent falls
- Continuous copper pan fabricated wall-to-wall
- Vertical upstands formed to meet masonry and siding interfaces
- Slate and shingle transitions rebuilt over copper with correct overlap
- Overflow pathways designed in case of extreme weather events
Result: A concealed copper solution that resolved chronic leakage without altering exterior appearance.
Case Study 5 — Roofline Re-Architecture on a Stone Estate
An estate home had accumulated small additions and changes that disrupted the original roof language. Water
was collecting at awkward junctions, and the massing no longer read as a coherent design.
- Existing roof planes documented and re-drawn as a single envelope
- Redundant or conflicting roof breaks simplified where structurally possible
- New copper valleys, saddles and junctions designed to match the revised geometry
- Slate fields re-laid to follow corrected lines and drainage
- Chimney, wall, and parapet interfaces re-detailed in copper
Result: The roof regained clear, disciplined geometry and reads once again as a deliberate design, not a patchwork.
Copper & Roof Architecture Materials
- 20 oz copper used for valleys, crickets, saddles, pans and crowns
- Hand-formed, soldered seams — no caulk-as-system solutions
- Copper integrated with slate and masonry as one assembly
- Proper reglet cuts and step flashings at all wall interfaces
- Underlayment and decking corrected before copper is installed
- No face-sealed trims, exposed fasteners or short-term metals

Most failures at heritage roofs begin where geometry gets complicated — chimneys, dead valleys, low-slope
transitions and wall interfaces. A Heritage Site Visit focuses on these high-risk zones and determines what
must be rebuilt in copper and how rooflines can be corrected for long-term service.
