Stop Water Damage Before It Starts: Choosing the Right Flashing

Flashing at exterior windows and doors is critical for shedding rainwater. It ensures a dry, durable building. Without proper flashing, water intrusion leads to moisture damage, deteriorated building materials, and indoor air quality issues. Homeowner callbacks can be costly, sometimes requiring removal of finishes or even replacement of structural elements. Flashing is your first line of defense, directing moisture away from vulnerable areas and protecting your structure long-term.

What to Look for in Flashing

Not all flashing is created equal. Before choosing a product, ask these key questions:

• Year-Round Installation – Can it be installed in any season, regardless of temperature?
• Extreme Durability – Will it perform in hot, cold, and harsh environments?
• Aggressive Adhesion – Does it stick firmly to the surface for lasting protection?
• UV Resistance – Can it withstand sun exposure for up to a year?
• Seamless Seal – Does it prevent leaks around nails and fasteners?
• Complete System Compatibility – Is it part of a full weather-resistive barrier system?

Henry® Flashing: Trusted Performance

Henry delivers Building Confidence^™ with high-performance window and door flashing. The Henry 1-2-3 Moisture Control System streamlines weatherization with a straightforward, three-step approach:

1. Choose the right barrier – A weather-resistive barrier (WRB) protects the structure.
2. Select reliable flashing – Henry® flashing integrates seamlessly with the WRB.
3. Use a proven sealant – Proper sealing ensures long-term moisture control.

This system is backed by a 15-year warranty covering materials and labor, helping you prevent costly leaks and callbacks.

Flashing Best Practices

Following best practices ensures flashing is effective. The National Association of Home Builders (NAHB) provides clear guidelines for both the design and construction phases. 

Design Phase

• • Integrate flashing shingle-fashion with the WRB, window/door frames, and trim.
  • Use caulks, sealants, and adhesives compatible with the WRB and windows/doors.
  • Include detailed flashing installation plans in construction documents.

Construction Phase

• • Inspect flashing installation for proper layering and WRB integration.
  • Never rely on caulk or sealant as a substitute for flashing.
  • Follow manufacturer specifications and local building codes.
