The Process
What's included
Roof inspection
We assess your roof material and condition first, and flag anything a roofer should look at.
Gentle soft-wash treatment
A low-pressure application of roof-safe cleaning solution kills moss, algae, and lichen at the root — no pressure washing, ever.
Protected landscaping
Gutters, downspouts, and surrounding plants are rinsed and protected throughout the job.
Natural clean-off
Treated growth dies and washes away with weather over the following weeks, leaving a clean roof without abrasion.
Why It Matters
More than just a clean look
Extends roof life
The black streaks on roofs are algae that literally feed on shingles. Removing them can add years to your roof's lifespan.
Protects coverage
Some insurers flag mossy, streaked roofs during renewals. A clean roof helps protect your coverage and home value.
Whole-home curb appeal
Your roof is a third of what people see from the street. A streak-free roof transforms the look of the entire house.
FAQ
Common questions
Won't pressure washing damage my shingles?
It absolutely would — that's why we never pressure wash roofs. Soft washing uses gentle, low-pressure application of cleaning solutions that do the work chemically, the method roofing manufacturers recommend.
How long do the results last?
Typically 2–4 years depending on shade and moisture. Roofs under trees may see regrowth sooner.
Is soft washing safe for all roof types?
We adjust our method for composition shingle, tile, and metal roofs. During the quote we'll confirm the right approach for yours.
Why do the streaks take time to disappear?
The treatment kills the growth immediately, but heavier moss and lichen release gradually with weather instead of being blasted off — that's what keeps your shingles safe.
