Roof Cleaning in Boardman, OH
In-house crews out of our Sharon, PA shop.
Boardman's black roof streaking is more visible than Youngstown's simply because so many houses here have big, uninterrupted, street-facing roof planes. On a wide 1960s ranch there is nowhere for algae streaking to hide, and it drives more cleaning calls than any actual performance concern.
Big Planes, Visible Streaking, Resale Pressure
A long low ranch roof presents one huge visible surface from the street. When the north slope streaks, the whole house reads as neglected, and in a market where Boardman homes sell fast on curb appeal that has real dollar value. Cleaning a roof before listing is one of the highest-return exterior spends available on a Boardman house.
Soft Wash, Not Pressure
Low-pressure application of a manufacturer-approved solution, dwell, rinse — the ARMA-specified method that GAF, Owens Corning, and IKO all warranty. Pressure washing blows granules off the mat and shortens the roof's life measurably. We do not pressure wash roofs.
Zinc Strips Work Well on Low-Slope Ranches
Because Boardman's pitches are shallow and the runs are long, a zinc or copper strip at the ridge distributes metal ions evenly down the whole plane with every rainfall. It is one of the more effective preventive add-ons in this housing stock, and it extends the re-clean interval by a couple of years for a modest cost during the cleaning visit.
What Is Roof Cleaning?
Roof cleaning is the removal of the black algae streaking, moss, lichen, and debris that build up on shingles. On Boardman 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
- 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.
- 2The solution is left to dwell so it kills the algae at the root rather than just bleaching the surface.
- 3Plantings, siding, and walkways are pre-wet and rinsed so nothing downstream is damaged.
- 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 Boardman, OH Home

- Green moss cushions along the shingle butts or in the valleys.

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 — Boardman
- How often do Boardman roofs need cleaning?
- Every four to six years on typical open subdivision lots, sooner on the shaded older streets north of US-224.
- Is the black streaking damaging my roof?
- It is algae and it holds moisture against the shingle, which does shorten life over time. But the primary reason Boardman owners call is appearance and resale, and that is a legitimate reason.
- What does roof cleaning cost in Boardman?
- Per square foot with a base call-out fee. Boardman's simple, accessible roof shapes usually price at the lower end of our range.
- Can you do the gutters at the same time?
- Yes, as a fixed add-on. On a long ranch with 5-inch gutters, clearing them during the same visit is a sensible bundle.
