Why Proper Flashing Is the Secret to a Leak-Free Roof

How Small Pieces of Metal Protect Your Home From Big Problems

Shingles might be the most visible part of your roof, but flashing is what really keeps water out. Flashing is the thin metal installed around chimneys, skylights, valleys, and vents that directs water away from vulnerable areas.

When flashing fails, leaks aren’t far behind.

✅ Where Flashing Matters Most

  • Chimneys and skylights

  • Roof valleys

  • Vent pipes and boots

  • Edges where roof planes meet

✅ Why Flashing Fails

  • Poor installation (caulk used instead of layered flashing)

  • Rust or corrosion over time

  • Storm damage loosening seals

✅ Risks of Ignoring Flashing Problems

Even a small flashing gap allows water intrusion, which can cause hidden rot or mold long before you notice interior stains.
