Roof-to-façade interfaces
Parapets, upstands, copings and adjoining facade zones are coordinated around structure, membranes, insulation and installation sequence.
Roofing, drainage and envelope interfaces
The roof is only resolved when water, structure and façade meet.
ALM coordinates falls, outlets, membranes, parapets, interfaces and adjoining envelope systems as one buildable design basis.

Where the interfaces are resolved
Start with the whole water path.
Falls and drainage strategy
Falls, outlets, overflows and drainage routes are developed against the available geometry and confirmed project criteria.
Membranes and continuity
Weather, air and thermal control layers remain continuous through junctions, penetrations and movement zones.
Construction-stage review
Current details and site evidence are reviewed while interfaces remain visible and corrective action is practical.
What the appointment needs
Confirm the project criteria, then carry the water path through every interface.
Current project basis
Roof geometry, rainfall and drainage criteria, specifications, structural zones, facade build-ups and outlet strategy.
Reviewable outputs
Coordinated interface details, drainage strategy, falls and outlet review, design notes and construction-stage observations.
The right point to appoint
When roofing, drainage and facade packages need one coordinated technical view.
