Architectural Sheet Metal and Roofing
Architectural sheet metal and roofing, followed through a third-year apprentice on a Halifax sheet metal contractor's architectural crew: the building envelope and roof safety, architectural metals, thermal movement and galvanic corrosion, roof edges, step, counter, apron, cricket and valley flashings, penetrations, parapets and copings, gutters and downspouts, standing seam roofing, traditional copper flat-lock and batten seam work, rainscreen wall cladding, snow, ice dams and condensation, heritage restoration, and a capstone restoring a historic church's copper roofs.

What you'll learn
- Explain the building envelope, the forces that drive water into buildings, and where architectural sheet metal fits, and plan roof work with the required fall protection
- Select architectural metals for their use, calculate thermal movement, detail fixed points and cleats, and prevent galvanic corrosion and harmful contact with other materials
- Form, fasten and join drip edges, membrane roof edges and gravel stops, including developed widths, tested fastener patterns, joints and corners
- Install step flashing, counterflashing, apron flashing, crickets, valleys and kick-out flashing so every piece laps the one below
- Flash pipes, curbs, supports, hatches and parapets, and build sloped copings with continuous cleats, movement joints and splice plates
- Size gutters and downspouts from rainfall intensity and drained area, hang them to slope and shed overflow outward, and place expansion joints
- Lay out, clip, seam and trim architectural and structural standing seam roofs to their tested assemblies, allowing for movement
- Make soldered flat-lock, batten seam, hand-seamed standing seam and conical copper roofing, with cleats, expansion fields and full-penetration solder
- Install drained and pressure-equalized rainscreen cladding over an air and water barrier, with designed girt and clip spacing, opening flashings and fire-compliant components
- Control snow, ice dams, wind and condensation with snow retention, eave protection, ventilation, vapour control and wind-resistant attachment
- Survey, document and restore heritage metal roofs by retaining, repairing and replacing in kind under conservation standards
- Plan, estimate, sequence, carry out and close out a heritage copper roof restoration with its take-off, schedule, inspections and records
