Soffit vs Fascia: Understanding the Critical Difference
Your home's soffits are working 24/7 to protect your property from water damage, pests, and structural deterioration. But when soffits fail, the consequences can be devastating—and expensive. In this comprehensive guide, we'll cover everything Myrtle Beach homeowners need to know about the critical differences between soffits and fascia.
What is a Soffit?
A soffit is the horizontal surface beneath the eave overhang of your roof—the exposed surface you see when you look up at your roofline from outside. Soffits bridge the gap between your home's exterior siding and the roofline, creating a finished appearance while serving critical functional roles.
Primary functions:
- Attic ventilation: Vented soffits allow cool air intake for proper attic airflow
- Weather protection: Shields roof rafters from rain, humidity, and coastal salt air
- Pest prevention: Seals gaps that birds, squirrels, and insects could use to enter your attic
- Aesthetic finish: Provides a clean, professional appearance to your roofline
What is Fascia?
Fascia is the vertical board mounted at the point where your roof meets the outer walls of your house. It runs along the roofline and is the board to which gutters are attached. Fascia provides the mounting point for gutter systems and creates a barrier between the edge of the roof and the elements.
Primary functions:
- Gutter support: Provides structural mounting for gutter systems
- Roof edge protection: Protects roof edges from water infiltration
- Rafter protection: Shields the ends of roof rafters from weather damage
- Aesthetic appeal: Creates a finished edge along your roofline

Why Both Matter for Coastal Homes
In Myrtle Beach and other coastal areas, both soffits and fascia face unique challenges that make their condition critical for home protection. Salt air, high humidity, intense UV exposure, and hurricane-force winds all take a toll on these components.
Coastal challenges:
- Salt corrosion: Accelerates material deterioration and fastener failure
- High humidity: Promotes mold, mildew, and wood rot
- UV exposure: Degrades protective coatings and causes material breakdown
- Storm damage: High winds can tear off poorly maintained soffits and fascia
