Complete Guide to Roof Eaves: Coastal Protection for Myrtle Beach Homes
Shocking Industry Truth
If you live within 3,000 feet of the South Carolina coast, your roof eaves face challenges that inland homes never encounter. Saltwater corrosion. Hurricane-force winds. Year-round humidity that breeds rot and mold.
Yet most Myrtle Beach homeowners don't understand what roof eaves are, why they matter, or how coastal conditions silently destroy them—until a $10,000+ repair bill arrives after the next storm.
This comprehensive guide explains everything about roof eaves for coastal homes: what they are, why they're critical for hurricane protection, the unique threats facing Grand Strand properties, and 7 proven strategies to prevent expensive eave damage.

What Are Roof Eaves? (And Why Coastal Homes Need Them)
Roof eaves are the horizontal edges of your roof that extend beyond the exterior walls of your home. Think of them as your roof's protective overhang—the part that creates shade on your walls and keeps rain away from your foundation.
While the term "eaves" sounds old-fashioned, these components serve critical modern purposes, especially for coastal properties in Myrtle Beach, North Myrtle Beach, Surfside Beach, and along the entire Grand Strand.
The Three Parts of Roof Eaves
Understanding eave anatomy helps you spot damage early:
Eave Components:
-
1.
Fascia Board: The vertical board attached to the ends of your roof rafters. This is where gutters attach. On coastal homes, fascia boards face constant assault from salt spray and moisture.
-
2.
Soffit: The horizontal underside of your eave overhang. Soffits contain ventilation holes that allow attic airflow—critical for preventing moisture buildup in humid coastal climates.
-
3.
Rafter Tails: The structural roof framing members that extend beyond your walls to create the overhang. When these rot from water damage, repairs become expensive structural projects.
Why Eaves Matter More on Coastal Homes
For Myrtle Beach properties, properly designed and maintained eaves provide four critical functions:
-
1.
Water Diversion: Eaves channel rainwater away from walls and foundations. During coastal thunderstorms that dump 2-3 inches per hour, this protection prevents water intrusion that leads to mold and structural damage.
-
2.
Wind Uplift Protection: Properly secured eaves resist hurricane winds. According to recent engineering studies, wind speeds of just 45 mph can cause eave failure if components aren't properly fastened—and Myrtle Beach regularly experiences 60+ mph gusts during tropical systems.
-
3.
Attic Ventilation: Soffit vents allow hot, humid air to escape your attic. Without proper eave ventilation, coastal humidity creates the perfect environment for mold growth and roof deck deterioration.
-
4.
Curb Appeal & Value: Well-maintained eaves enhance your home's appearance and resale value. Damaged, rotting eaves immediately signal deferred maintenance to potential buyers.
