The Different Parts of a Roof

Understanding the anatomy of your roof helps homeowners make smart decisions when reviewing an estimate or identifying damage.

Core Components:

• Roof Shingles – The outermost, visible layer
• Underlayment – Provides water resistance under shingles
• Valleys – The channels where two roof planes meet
• Decking – The plywood base beneath everything
• Flashing – Metal pieces that protect edges and valleys
• Fascia – The front board along your roof’s edge
• Soffit – Provides attic ventilation under roof overhangs
• Ridge Vents – Key to attic temperature and moisture control

Gutters & Downspouts – Essential for directing water away from your foundation

One of the most commonly neglected and most frequently damaged parts of the roof is the valley area, especially in tile roofs. We see more repair calls for tile valleys than any other component. Valleys are prone to debris buildup and water flow issues, making them especially vulnerable over time.
