Most homeowners focus on shingles when replacing a roof, but two of the most important parts of any roofing system are proper flashing and attic ventilation.

At 4th Perry LLC, we regularly inspect roofs throughout Columbus and find major issues caused by improper flashing and poor ventilation — even on newer roofs.

What Is Roof Flashing?

Flashing is the metal waterproofing system installed in areas where water is most likely to enter the home.

Critical flashing areas include:

• Chimneys
• Roof-to-wall transitions
• Pipe penetrations
• Valleys
• Around siding and gutters

One of the most overlooked components is kick-out flashing, which directs water away from siding and into the gutter system. Without it, water can run behind siding and cause rot, mold, and interior damage.

Proper step flashing should also be installed piece-by-piece anywhere the roof meets a wall. Shortcuts in these areas are one of the leading causes of roof leaks.

Why Roof Ventilation Matters

Your attic needs balanced airflow to properly remove heat and moisture.

A proper ventilation system includes:

• Intake ventilation through soffits
• Exhaust ventilation through ridge vents or roof vents

Without proper ventilation, homeowners may experience:

• Higher energy bills
• Mold or moisture in the attic
• Premature shingle aging
• Ice dams in winter
• Reduced roof lifespan

Roofing Is More Than Just Shingles

A roofing system only performs correctly when all components work together — shingles, flashing, ventilation, underlayment, and drainage.
