Cedar Roof Cleaning
in Hilton Head Island, SC
Salt air, subtropical heat, and year-round humidity make Hilton Head one of the toughest places in America for cedar roofs. Moss, algae, and black streaks eat your shingles alive. Our professional soft-wash cleaning and premium sealing protects your investment and restores your roof's natural beauty.
Cedar Roofs on Hilton Head Island Face a Unique Challenge
Hilton Head Island's combination of Atlantic Ocean salt air, subtropical heat, and near-constant humidity creates some of the most aggressive conditions for cedar roof deterioration in the United States. Unlike inland climates, there is no dry season to slow biological growth — moss, algae, lichen, and black algae streaks establish and spread year-round.
The island's maritime environment also means cedar wood fibers are constantly breaking down faster than in other regions. Salt particles carried on the breeze settle into cedar shingles, accelerating weathering and making it easier for spores to take hold. What begins as a cosmetic stain quickly becomes a structural problem.
Professional cedar roof cleaning in Hilton Head Island, SC is one of the most cost-effective maintenance decisions a homeowner can make. Replacing a cedar shake roof on the island typically runs $25,000 to $60,000 or more. A professional clean and seal is a fraction of that cost — and it works.

What's Damaging Your Cedar Shake Roof
Hilton Head Island's coastal position in the South Carolina Lowcountry makes it one of the most challenging environments in the Southeast for cedar roofs. Here's what we find on nearly every cedar roof we inspect on the island:
Moss & Mold Growth
Hilton Head's 52+ inches of annual rainfall and high humidity create perfect conditions for moss and mold to take root between shingles, trapping moisture and accelerating rot.
Black Algae Streaks
Dark staining from Gloeocapsa magma algae is extremely common in Hilton Head's coastal climate. It signals active biological growth that is eating into your shingles daily.
Salt Air Corrosion
Being a barrier island, Hilton Head roofs face constant salt spray. Salt particles penetrate cedar fibers, weakening the wood's natural oils and dramatically shortening shingle lifespan.
Lichen & Wood Rot
Lichen adheres to cedar at the cellular level and is notoriously difficult to remove. Left unchecked on Hilton Head's warm roofs, it leads to wood softening, splitting, and full shingle failure.
UV Weathering
South Carolina's intense sun grays and dries out cedar shingles quickly. Unprotected wood loses oils, becomes brittle, and is far more vulnerable to biological invasion and moisture damage.
Tree Canopy Debris
Hilton Head's beautiful live oaks and pines drop debris year-round. Accumulated leaves and pine straw stay wet for days, creating ideal nurseries for moss and fungal growth on cedar.
The Same Roof, Restored — Not Replaced
This is what a proper cedar roof cleaning and sealing looks like. No replacement, no tear-off. Just professional soft-wash cleaning followed by a penetrating sealant that protects for years.
How We Clean Cedar Roofs on Hilton Head
We use a proven low-pressure soft-wash process engineered specifically for cedar shake roofs. High-pressure washing destroys cedar fibers — we never use it, period. Here's exactly what happens when we service your Hilton Head Island property:
Free Inspection & Assessment
We evaluate your roof's condition in person — identifying moss, lichen, algae, damaged or cupped shingles — and provide an honest assessment of whether cleaning is the right call versus replacement. No pressure, no obligation.
Full Property Protection
Before any treatment begins, we pre-wet all vegetation, protect your Lowcountry landscaping with coverings, and secure gutters and downspouts. Hilton Head's native plants and coastal landscaping are treated with care throughout the process.
Soft-Wash Biological Treatment
A biodegradable cleaning solution is applied at genuinely low pressure — never more than a garden hose. The solution kills moss, algae, lichen, mildew, and mold at the root level. No scrubbing, no blasting. Safe for your coastal waterways and Beaufort County environment.
Complete Rinse & Inspection
We rinse the roof and surrounding surfaces thoroughly, then walk the full perimeter to confirm all biological growth has been eliminated and the surface is clean, even, and ready for sealing.
Premium Cedar Sealant Application
A penetrating, professional-grade cedar sealant is applied to protect the wood against Hilton Head's salt air, UV exposure, future moisture intrusion, and biological regrowth. Quality sealant lasts 5 to 7 years in Lowcountry conditions.
