Roof cleaning in the greater Columbia area
Those black streaks are not dirt. They are algae feeding on the limestone in your shingles, and they spread down the shaded side of the roof a little further every summer. We treat them at low pressure so the streaks die off and the shingles stay put. No pressure washer ever touches the roof.

Included in every roof cleaning job
The whole roof, not just the side you can see from the road.
- Every slope treated, including the shaded side where the streaks start.
- Moss and lichen treated so they lose their grip and release with the next few rains.
- Gutters flushed of whatever the treatment washes down.
- Plants protected. Beds pre-wetted and rinsed down after, runoff kept off the lawn.
- Walkthrough if you are home, and photos of the roof from the ladder by text when we finish.
- Insured work, certificate sent to you or your HOA on request.
Why we never pressure wash a roof
A pressure washer takes the protective granules off the shingle along with the streak. You get a clean roof for a season and a roof that fails years early. Shingle makers say so in their warranty terms, and so do we.
A roof soft wash works chemically. A cleaning solution goes on at garden-hose pressure, kills the algae at the root, and the streaks fade as it works. Moss and lichen die on the day and let go over the following weeks of rain, because scraping them off takes shingle with them.
Where the owner does use pressure is on the ground afterwards: walks and drives get rinsed so nothing the roof shed is left behind.
From satellite photos of the roof
Satellite measurements give us the roof area and the pitch, so most roof quotes need no site visit. A fixed price before we start.
Streaks gone on the day, lichen over a few weeks
The black streaks are gone when we leave. Thick moss and lichen turn white as they die and wash away with rain, which is the safe way to lose them.

Questions we get asked
Will it damage my plants?
Beds get soaked before we start and rinsed again after, which dilutes anything that reaches them. Tell us about anything delicate and we cover it.
How often should a house be washed?
In the greater Columbia area's humidity, most homes want it every 12 to 18 months. Shaded and tree-lined lots are closer to 12.
Do I need to be home?
No, as long as we can get to the whole property, with any gates left open, and reach an outside tap. We text before we arrive and again when we finish, with photos.
What if it rains?
We reschedule at no charge. Rain after the wash is fine. The work is already done by then.
Can I just pressure wash my roof myself?
Please do not. A pressure washer strips the granules that protect the shingle. Our guide to soft washing versus pressure washing a roof explains why, and what works instead.
Do you walk on the roof?
As little as possible. Most roofs are treated from the ladder and the edge. Walking on shingles is what causes the damage the cleaning is meant to prevent.
How long does a roof stay clean?
Three to five years is typical in the greater Columbia area. Roofs under trees and on the shaded side of the house are at the shorter end.
Often booked with roof cleaning
Same visit, one trip. A house wash and a roof clean together is the most common order we get.
