Emergency Flashing Repair in Seattle & the Eastside
When flashing fails, water can enter the building envelope quickly and cause serious damage. Emergency flashing repair is often needed after heavy rain, wind-driven storms, or when improper installation allows water to bypass gutters, roofs, or siding and run directly into wall assemblies.
Synapse Construction provides emergency flashing repair services throughout Seattle and the Eastside, focusing on identifying the source of failure and repairing it correctly — not just covering it up.
What’s Happening
Flashing is designed to direct water safely away from vulnerable transitions on a building. When flashing is missing, damaged, or improperly installed, water follows gravity and wind pressure straight into the structure.
Common situations that trigger emergency calls include:
- Sudden interior leaks during heavy rain
- Water dumping behind siding at roof-to-wall transitions
- Gutter ends directing water into walls
- Leaks appearing near ceilings, windows, or exterior corners
Often, the visible leak is only a symptom of a deeper flashing failure behind the exterior cladding.
Why Flashing Failures Are Urgent
Uncontrolled water entry can cause damage rapidly, especially in the Pacific Northwest climate.
Delaying repair can lead to:
- Hidden rot inside wall cavities
- Mold growth and indoor air quality concerns
- Structural deterioration
- Insulation failure and energy loss
- Escalating repair costs
Early intervention typically allows for smaller, more targeted repairs.
How Synapse Construction Handles Emergency Flashing Repairs
We take an investigation-first approach to emergency flashing repair. Our goal is to identify exactly how water is entering the building envelope and correct the failure at its source.
Our process typically includes:
- Exterior inspection and water path analysis
- Selective removal of siding or roofing materials (only where needed)
- Evaluation of existing flashing, WRB, and transitions
- Installation of proper flashing details, including kick-out flashing, step flashing, and head flashing where required
- Restoration of waterproofing layers
- Reinstallation and finishing of exterior materials to match existing conditions
This method prevents repeat leaks and protects the surrounding structure.
Common Flashing Failures We Find
During emergency repairs, we frequently discover:
- Missing or undersized kick-out flashing
- Improper roof-to-wall flashing transitions
- Flashing installed behind, rather than over, WRB layers
- Window and door openings without head flashing
- Aging or corroded metal flashing
These issues are often concealed until a leak becomes active.
