Why Cedar Roofs in Highlands Suffer More Than Most
Highlands, NC sits at over 4,100 feet in the Blue Ridge Mountains and is one of the wettest towns in the Eastern United States. With over 80 inches of precipitation per year and humidity consistently between 76 and 79% year-round, cedar shake roofs here face relentless moisture exposure. Heavy tree canopy and limited sunlight turn your cedar roof into a breeding ground for moss, algae, lichen and black mold year after year.
Left untreated, these growths physically break down cedar fibers, trap moisture, accelerate rot and cut years off your roof's lifespan. Regular professional cleaning stops the damage before it becomes a costly replacement.
Annual precipitation, among the highest in the Eastern US
Year-round relative humidity, ideal for moss and algae growth
Rain days per year keeping cedar shakes damp far longer than average
Elevation with mountain shade that slows drying time on cedar shakes
What We Treat
Common Cedar Roof Problems in Highlands Homes
Here is what we typically find when inspecting a cedar shake roof in Highlands and why each issue needs prompt attention.
Moss Buildup
Thick moss colonies trap moisture directly against your shakes, causing the wood to stay perpetually damp. This accelerates rot, splitting and structural breakdown. Highlands' shaded, wet conditions make moss the number one cedar roof enemy here.
Black Algae Streaks
Those dark streaks running down your cedar roof are airborne algae that feed on roofing materials. It spreads rapidly in humid mountain climates, degrades cedar fibers and reduces curb appeal if left untreated.
Lichen and Mold
Lichen embeds itself into cedar wood fibers and etches into the surface itself. Combined with mold and mildew, it compromises the structural integrity of your shakes and can void manufacturer warranties.
Debris Accumulation
Highlands is surrounded by dense hardwood and conifer forests. Fallen leaves, pine needles and twigs create damp organic layers where spores thrive and clog gutters, leading to water backup and damage.
Premature Weathering
Biological growth strips protective oils from cedar, causing uneven graying and early breakdown. Regular cleaning preserves cedar's natural color and extends its structural durability significantly.
Hidden Rot and Splitting
Moisture held by moss creates freeze-thaw damage especially common in Highlands winters. Shakes begin to split, cup and rot from the inside out, often invisible until significant structural damage has already occurred.

How We Clean Cedar Roofs in Highlands
Most companies use pressure washers. We never do. High-pressure washing destroys cedar fibers, strips protective oils and forces water under shingles. At Lion Renew we use a proven soft-wash process built specifically for cedar shake roofs.
Free Roof Inspection
We identify the extent of moss, algae and lichen growth, check for damaged shakes, assess drainage and note overhanging branches contributing to shade and moisture. You get an honest assessment with no surprises.
Debris Removal
We clear all loose debris including leaves, pine needles and compacted organic matter using low-impact air blowers and soft brushes. This exposes the full extent of biological growth and ensures treatments penetrate effectively.
Cedar-Safe Soft Wash Treatment
We apply our biodegradable treatment solution using low-pressure soft wash equipment. It kills moss, algae, lichen, mold and mildew at the root level without harsh acids or high-pressure water. Your landscaping and roof stay fully protected.
Gentle Low-Pressure Rinse
After the treatment does its work, we perform a careful rinse using a standard garden hose, never a power washer. This removes dead biological matter without stripping cedar oils or forcing water beneath your shakes.
Post-Treatment Inspection
Once clean, we walk the roof again to identify any shakes needing attention. We provide written recommendations for preventive maintenance and can advise on zinc strip installation or trimming overhanging branches.

Common Questions
Cedar Roof Cleaning in Highlands, NC: FAQ
How often should I clean my cedar roof in Highlands, NC?
Given Highlands' high rainfall and persistent humidity, we recommend professional cleaning every 2 to 3 years. Homes under heavy tree cover may need annual treatment. Regular maintenance is far more cost-effective than premature cedar roof replacement, which can run $15,000 or more.
Is pressure washing safe for my cedar shake roof?
No. Pressure washing rips wood fibers, removes natural protective oils and forces water beneath shingles. It dramatically accelerates aging and splitting. At Lion Renew, we never use pressure washers on cedar roofs.
Can I clean my cedar roof myself?
DIY cedar roof cleaning is not recommended. Improper bleach concentrations can damage cedar and discolor shingles. Working on a sloped roof also carries serious fall risk. Professional cleaning includes a condition assessment that catches developing problems before they become expensive repairs.
Will cleaning extend my cedar roof's lifespan?
Absolutely. Moss and algae physically degrade cedar fibers and hold moisture that causes rot. Regular cleaning can add a decade or more to your roof's life in Highlands' demanding climate.
How long does a cedar roof cleaning take?
Most residential cedar roof cleanings in Highlands take 3 to 6 hours depending on roof size and severity of growth. We give you an accurate time estimate during your free consultation.
