Case Study: Custom Flashing Production for Coastal Construction in Rhode Island

Introduction: Why Flashing Matters in Coastal Rhode Island

In coastal regions of Rhode Island—such as Newport, Narragansett, Westerly, and South County—custom flashing plays a critical role in protecting buildings from harsh environmental conditions.

Unlike inland construction, coastal projects require flashing systems that can withstand:

Salt air corrosion
Heavy rain and wind-driven water
Temperature fluctuations
Expansion and contraction of materials

Flashing is not just a finishing detail in these environments—it is a primary defense against water ingress and structural damage.

This case study explores a small roll forming and fabrication business producing custom flashing for coastal construction projects, including:

Machine setup and fabrication process
Material selection
Environmental challenges
Production problems
Solutions implemented
Final performance results
