Roof Cleaning in Austintown, OH

In-house crews out of our Sharon, PA shop.

Those black streaks running down your north slope are gloeocapsa magma algae, not dirt, and pressure washing them off will cost you shingles.

Roof Cleaning in Austintown, OH
Soft-wash cleaning — half cleaned, half still streaked with algae.

Why Shaded Austintown Streets Streak First

The older township grid near Mahoning Avenue and the mature-tree streets around Raccoon Road hold morning damp on north-facing slopes well past sunrise. Algae feeds on limestone filler in the shingle mat, so the shaded slope streaks years before the sunny one. It is cosmetic at first and moisture-retentive later.

Soft Wash, Not Pressure

We apply a low-pressure manufacturer-approved solution, let it work, and rinse gently — that kills the organism without stripping granules or voiding your shingle warranty. Pressure washing an asphalt roof takes years off it, which is why no manufacturer endorses it.

What Is Roof Cleaning?

Roof cleaning is the removal of the black algae streaking, moss, lichen, and debris that build up on shingles. On Austintown homes the black streaks are almost always Gloeocapsa magma, an airborne algae that feeds on the limestone filler in asphalt shingles. It is cosmetic at first and destructive later — moss and lichen hold moisture against the shingle and shorten the life of the roof.

How Roof Cleaning Is Done Correctly

  1. 1Soft washing: a low-pressure application of a cleaning solution that kills the organism, followed by a gentle rinse. Pressure never exceeds what a garden hose delivers.
  2. 2The solution is left to dwell so it kills the algae at the root rather than just bleaching the surface.
  3. 3Plantings, siding, and walkways are pre-wet and rinsed so nothing downstream is damaged.
  4. 4Valleys and gutters are cleared of debris in the same visit, since that is where moisture sits longest.

Safe Cleaning Practice

  • Soft wash only — it is the method ARMA and the shingle manufacturers accept.
  • Clean before moss establishes a root structure, not after it has lifted the shingle edges.
  • Address the shade and drainage that let it grow: trim overhanging limbs, clear the gutters.
  • Consider zinc or copper strips at the ridge to slow regrowth.

Methods to Avoid

  • Pressure washing an asphalt roof. It blasts off the granules that are the shingle's UV protection and will void the manufacturer warranty.
  • Scraping or wire-brushing moss off. It takes the granules with it.
  • Undiluted bleach with no plant protection.
  • Walking a wet, algae-covered roof — it is as slick as ice.

Warning Signs on a Austintown, OH Home

  • Black streaks running down the slope, usually worst on north-facing planes.
  • Green moss cushions along the shingle butts or in the valleys.
  • Crusty gray-green lichen spots that will not rinse off.
  • Granules collecting in the gutters.
  • Debris packed in the valleys holding moisture.

What Drives the Cost of Roof Cleaning in Austintown

  • Roof square footage and pitch.
  • How heavy the growth is and whether it is algae, moss, or lichen.
  • Access and landscaping protection required.
  • Whether gutter cleaning and minor repairs are bundled in.

Path 1 — Insurance claim

For wind, hail, or storm-driven damage. We walk the roof with your insurance adjuster and document what we find so nothing that should be covered gets missed. We are not a public adjuster — that is a separate PA license — and we do not negotiate the settlement. We document damage, meet the adjuster, and rebuild what the carrier approves to code and to manufacturer spec.

Path 2 — Retail with financing

For roofs simply reaching the end of their life. 0% interest financing on shorter terms and long-term financing that keeps monthly payments low. Runs through a lending partner and is subject to credit approval. We walk through both paths in the free in-home estimate before you sign anything. See financing details →

Frequently Asked Questions — Austintown

Will cleaning damage my shingles?
Not with soft wash. High pressure does, which is why we do not use it on asphalt.
How long does it stay clean?
Typically three to five years in Austintown depending on shade. Copper or zinc strips at the ridge extend that.
Is it worth doing before selling?
Yes — a streak-free roof reads as a newer roof to buyers, and it is a fraction of a replacement.

I called Penn Ohio for a roof repair estimate on my home recently. Gary came to my home and I could tell that he cares about doing the best for the customer. He gave me a lot options to choose from and I felt very comfortable and not like he is trying to take advantage of me like other companies. 10/10 guy.

These guys were great to work with. I've dealt with contractors that want to spend two hours of my time hitting me with a PowerPoint followed by high pressure tactics to commit immediately. They offer one price if I sign today but magically
