Roof Cleaning

That dark streaking on your shingles is not dirt. It is a bacteria called Gloeocapsa magma, and it has been breaking down your roofing materials the whole time it has been up there.

The problem

The instinct is to blast it off with a pressure washer. High pressure strips the granules from asphalt shingles — the granules that protect the asphalt from UV and keep the roof weather-tight. You get a clean-looking roof that just lost years of its lifespan in one afternoon.

Our approach

Soft washing: low pressure plus the correct solution that kills algae, moss, and lichen at the root. Our drones deliver it across every section — including steep and awkward areas — without anyone walking on your shingles.

  • Kills algae and moss at the root, so results last
  • No granule loss from high pressure
  • Reaches steep and awkward roof sections
  • Nobody walks on your shingles

How it works

What to expect from our roof cleaning

  1. 01

    Roof condition assessment

    We identify algae, moss, and lichen growth and confirm the roofing material so the right solution is used.

  2. 02

    Low-pressure solution application

    A cleaning solution is applied by drone to kill algae and moss at the root rather than just rinsing the surface.

  3. 03

    Gentle rinse across every section

    Steep and awkward areas are reached from the air at low pressure, with no one walking on your shingles.

  4. 04

    Lasting, granule-safe result

    Because growth is killed at the root and granules stay intact, the roof stays clean far longer than a pressure blast.

FAQ

Frequently asked questions

What are the black streaks on my roof?

They are caused by Gloeocapsa magma, a hardy algae that feeds on the limestone filler in asphalt shingles. Left alone it breaks down roofing material and shortens the life of your roof.

Why is soft washing better than pressure washing a roof?

High pressure strips the protective granules from asphalt shingles, taking years off the roof’s lifespan. Soft washing uses low pressure and the correct solution to kill growth at the root without damaging the shingles.

Does anyone walk on my roof during cleaning?

No. Our drones deliver the solution and rinse from the air, including steep and hard-to-reach sections, so there is no foot traffic to loosen granules or crack tiles.
