The key detail that determines the integrity of your entire building envelope.
At the Peter Ross Group, we fabricate metal flashings to exact tolerances and stand behind every transition detail. Because when we handle the roofing, the waterproofing, and the flashing, we own the performance of the entire envelope, not just our piece of it.

Our Metal Flashing Capabilities
We engineer and fabricate custom metal flashing designed specifically for the demands of your project:
- Roofing Terminations: Parapet caps, drip edges, and counterflashing that secure the roofing membrane and direct water away from the building facade.
- Waterproofing Transitions: Custom metal detailing at every point where below-grade or at-grade waterproofing meets the above-grade structure.
- Balcony & Terrace Edges: Precision flashing that performs flawlessly and meets the aesthetic standards of high-end residential and commercial developments.
- Custom Fabrication: Fabricated to fit the exact specifications of the membranes and coatings we install.

The Peter Ross Group, together with Pacific Waterproofing, Universal Polymers, WeatherSeal, Peter Ross Roofing, and Peter Ross CA, is a full-scope Division 7 contractor.
That means one team, one point of accountability, and zero coordination gaps across:

- At-grade plaza decks, sidewalks, and paver systems
- Pedestrian waterproofing for balconies and roof terraces
- Commercial roofing systems
- Metal flashing across all scopes

A Legacy Built on the Details
