Algae and Black Streak Removal in Kent, WA
Algae and Black Streak Removal in Kent
Those dark streaks on Kent roofs are algae thriving in the damp, shaded conditions. We dissolve the colonies at the source so the staining is removed, not just rinsed away.
Left alone, algae traps moisture and works with moss to wear roofs down faster. Our soft wash treatment clears the streaks and leaves a preventive layer that resists regrowth.
What's Included in our Algae and Black Streak Removal service?
Source Removal
We dissolve the algae colonies causing dark streaks rather than masking them temporarily.
Moisture Control
Clearing algae removes the moisture film that accelerates wear on Kent roofs.
Regrowth Resistance
A preventive treatment after cleaning helps keep streaks from returning quickly.

Frequently Asked Questions
Roof Cleaning can be complex, and we’re here to provide answers to common questions. Here are some frequently asked questions from our clients.
Frequently Asked Questions about Roof Cleaning Kent, WA
How often should I clean my roof in Kent, WA?
With our wet Western Washington climate, most Kent roofs benefit from a professional cleaning every 18 to 24 months. North-facing slopes and roofs shaded by Douglas firs hold moisture longer, so they often need attention sooner to stop moss from rooting under shingles.
What kills moss on a roof without damaging shingles?
We use a low-pressure soft wash with treatments that break down moss and algae at the root rather than blasting them off. High pressure strips granules from composition shingles and splits cedar shakes, so for Kent roofs we rely on chemistry and gentle rinsing, not force.
Why does moss grow so heavily on Kent roofs?
Kent sits in a high-rainfall pocket of King County with long damp seasons from October through March. Cool temperatures, tree cover, and constant moisture create ideal conditions for moss, algae, and lichen, especially on shaded and north-facing sections of a roof.
Will roof cleaning extend the life of my roof?
Yes. Moss traps water against the roof deck and lifts shingle edges, which leads to rot and early failure. Removing growth and applying preventive treatment protects the underlayment, helps preserve manufacturer warranties, and adds years of usable life to the roof.
Do you clean cedar shake and metal roofs too?
We do. Cedar shake, composition shingle, metal, and tile all behave differently, so each gets a tailored approach. Cedar needs careful low-pressure work to protect the wood, while metal and tile in the Kent area respond well to targeted soft wash methods.
Is roof moss treatment safe for my landscaping?
We take care to protect the plants and gardens around your Kent home. We pre-wet vegetation, control runoff, and rinse surrounding areas after treatment so your landscaping stays healthy while the moss and algae on the roof are dealt with properly.
Frequently Asked Questions about Algae and Black Streak Removal
What causes black streaks on roofs in Kent?
Those dark streaks are algae that thrives in Kent's damp, shaded conditions, feeding on the limestone filler in composition shingles.
Can algae stains be fully removed?
Yes. Our soft wash treatment dissolves the algae colonies so streaks are removed at the source rather than temporarily masked.
Does algae harm my roof?
Over time it does. Algae holds moisture against the shingles and works alongside moss to accelerate wear on Kent roofs.
How do you prevent algae from returning?
We apply a preventive treatment after cleaning that resists regrowth, and we suggest trimming overhanging branches to reduce shade and moisture.
