Protecting Your Missouri Home: The Critical Role of Roof Flashing
Flashing may be the unsung hero of your roofing system, but it’s essential for keeping your home dry. Here’s why flashing matters—and how to make sure yours is doing its job:
What Is Roof Flashing?
Flashing is thin metal installed around roof joints, chimneys, vents, and valleys. It directs water away from vulnerable areas, preventing leaks.
Why It Fails
- Improper Installation: Poorly installed flashing can pull away or crack.
- Aging & Weather: Missouri’s storms and temperature swings can rust or loosen flashing over time.
- DIY Repairs: Inexperienced fixes often overlook flashing, leaving gaps for water intrusion.
Signs of Flashing Trouble
- Water stains on ceilings or walls
- Visible rust or gaps around chimneys or vents
- Dripping water inside after storms
