Roof Washing in Columbus, OH | Soft Wash Roof Cleaning
Your roof is one of the most important (and expensive) parts of your home — and it’s also one of the most commonly neglected. Using proven soft washing techniques that remove black streaks, algae, moss, and organic growth without damaging your shingles.
If your roof has dark stains or looks older than it should, it’s not just dirt — it’s usually algae (Gloeocapsa Magma) feeding on your shingles. Our roof washing service restores your roof’s appearance and helps extend its lifespan.
Why Roof Washing Is Important
Those black streaks on your roof aren’t just cosmetic. Over time, organic growth can:
-
Break down asphalt shingles
-
Trap moisture and accelerate roof aging
-
Reduce your home’s curb appeal
-
Lead to premature roof replacement
Routine roof washing helps protect your investment, improve energy efficiency, and keep your home looking its best.
Our Soft Wash Roof Cleaning Process
We never use high pressure on roofs; pressure washing can void warranties and cause permanent damage. Instead, we use a low-pressure soft wash system designed specifically for roofing materials.
​
​Our process includes:
-
A thorough roof inspection
-
Application of a specialized cleaning solution
-
Gentle removal of algae, moss, and lichen
-
Safe rinse with low-pressure water
This method kills organic growth at the root, preventing rapid regrowth and delivering longer-lasting results.

Frequently Asked Questions About Roof Washing
​
How long does roof washing last?
Most roofs stay clean for 2–3 years, depending on shade, tree coverage, and moisture levels.
​
What causes black streaks on my roof in Ohio?
Ohio’s humidity and shade create ideal conditions for algae growth, especially Gloeocapsa Magma, which feeds on limestone fillers in shingles.
​
Why does my roof get dirty faster on one side?
North-facing and shaded roof slopes retain moisture longer, allowing algae and moss to grow more aggressively.
​
Is roof algae alive or just dirt?
It’s a living organism. That’s why rinsing alone doesn’t work — it must be chemically treated to stop regrowth.
