Demarest sits in one of the most beautiful, tree-lined corners of Bergen County and that natural shade is exactly what makes cedar roofs here so vulnerable. Without direct sunlight to dry them out, cedar shakes stay damp for hours after rain, creating the perfect environment for moss, lichen, algae, and black algae streaks to take hold.
Left untreated, these organisms work their way between shingles, lift edges, hold moisture against the wood grain, and accelerate rot. What starts as a cosmetic issue becomes a structural one. Regular cedar roof cleaning in Demarest, NJ is one of the most cost-effective ways to protect a roof that can be very expensive to replace.
Our soft-wash process is specially designed for cedar shake. No high-pressure blasting, no fiber damage, no shortcuts. Just a thorough, professional clean followed by a penetrating sealant that protects for years.
What's Damaging Your Cedar Shake Roof
Bergen County's humid climate and dense tree canopy create ideal conditions for roof growth. Here's what we commonly find on cedar roofs in Demarest and surrounding towns:
Moss Growth
Moss roots lift shingle edges and trap moisture against the wood, causing premature rot and cracking.
Black Algae Streaks
Dark stains caused by Gloeocapsa magma algae spread across roof surfaces and are a sign of active biological growth.
Lichen and Mildew
Lichen bonds directly to cedar fibers. Once attached, it cannot be removed with water alone and causes surface erosion.
Wood Decay and Rot
Persistent moisture trapped by organic growth leads to softening, splitting, and eventual structural failure of cedar shingles.

We use a proven low-pressure soft-wash process designed specifically for cedar shake and wood shingle roofs. High-pressure washing destroys cedar fibers and we never use it.
Inspection and Assessment
We evaluate your cedar roof's condition, identify problem areas including moss, lichen, algae, and damaged shingles, and confirm the roof is a good candidate for cleaning versus replacement.
Property Protection
We pre-wet all landscaping, cover plants near the roofline, and protect gutters and downspouts before any treatment begins.
Soft-Wash Treatment
A biodegradable cleaning solution is applied at low pressure to kill moss, algae, lichen, and mildew at the root. No scrubbing, no pressure blasting. The solution does the work safely.
Rinse and Inspection
We thoroughly rinse the roof and surrounding areas, then do a final walkthrough to confirm all growth is removed and the surface is clean and even.
Cedar Sealant Application
A penetrating cedar sealant is applied to protect the wood from future moisture intrusion, UV damage, and biological regrowth. Quality sealant lasts 5 to 7 years.
