How it works
Properly setting flashings before shingles are installed protects the critical roof and wall intersections where leaks begin.
Explore the house to see how edge flashing, step flashing, valleys, and other critical openings work together.
The risks
Left unchecked, moisture can create costly damage behind the surfaces you see. A complete flashing system helps stop it at the exterior.

Persistent moisture creates the conditions mold needs to spread.

Trapped water weakens framing and sheathing over time.

Vulnerable roof edges allow backups to reach the structure.

Leaks spread into drywall, insulation, and attic spaces.

Moisture reduces insulation performance and creates conditions for long-term damage.
