After Roof Cleaning
Before Roof CleaningBlack streaks running down a roof are one of the most common reasons a Lexington homeowner starts researching a full roof replacement — and one of the most common cases where that's not actually necessary. Those streaks are almost always gloeocapsa magma, a light-feeding bacteria that spreads across asphalt shingles and feeds on the limestone filler most modern shingles contain. It's not structural damage. It's a living organism sitting on the surface, and it can be removed without ever putting weight, pressure, or a ladder on the shingles themselves.
Every Roof Is Different
Roofing materials we clean — and how we adjust for each.
Asphalt Shingle
The most common roof in Lexington and the one most prone to gloeocapsa magma — the black algae that feeds on limestone filler in modern shingles.
Architectural Shingle
Heavier and more textured than standard three-tab, which means algae and moss have more surface to grip. Same soft wash method, slightly longer dwell time.
Metal Roofing
Can handle a touch more solution strength, but oxidation and streaking still call for a gentle hand to avoid dulling the finish.
Tile Roofing
Porous and prone to moss in shaded valleys. We treat gently to avoid cracking or dislodging individual tiles.
Slate
One of the more delicate materials we clean — low concentration, longer dwell, and zero foot traffic on the roof itself.
Cedar Shake
Needs the gentlest approach of any roofing material. Too much solution strength can accelerate wood breakdown instead of preventing it.
Our Roof Cleaning Method
Pressure on shingles is how roofs get destroyed. We don't do that.
The entire process is applied from the ground — no ladders on your shingles, no boots near your flashing, no foot traffic putting weight where it doesn't belong.
Pre-soak landscaping & gutters
Every plant, bed, and gutter run gets wet down before any solution touches the roof — and again once we finish.
Apply solution from the ground
The entire roof surface gets even coverage across all slopes, valleys, and around vents, without anyone climbing up.
Dwell 15–20 minutes
The solution breaks the bacteria's bond to the shingle, so it rinses off clean instead of leaving streaks.
Low-pressure rinse
We rinse the roof and surrounding landscaping. Remaining staining keeps fading for weeks as rain clears the rest.
Do I need to be home for roof cleaning?
No. The entire process happens from the ground, so as long as we have clear access to the property, most customers aren't home when we do the work.
Why we never put a pressure washer on a roof.
Pressure on asphalt shingles knocks loose the granules that actually protect them from UV damage and water intrusion — once those granules are gone, they don't come back, and the roof's remaining lifespan drops by years, not months. It might look dramatically cleaner for a season, but it's trading a cosmetic fix for real, permanent damage.
Soft washing works differently: a cleaning solution under 100 PSI breaks the algae's bond to the shingle chemically, and a low-pressure rinse clears it away. GAF, Owens Corning, and CertainTeed — three of the largest shingle manufacturers — all recommend soft washing as the safe method for exactly this reason, and pressure washing is one of the more common ways a shingle warranty gets voided without the homeowner realizing it.
Will soft washing void my roof warranty?
No. Soft washing is the manufacturer-recommended cleaning method for every major asphalt shingle brand. Pressure washing is what typically voids warranties, because it blasts away the protective granules on your shingles.
There's a side benefit to roof cleaning most homeowners never connect to their energy bill. Dark algae and organic growth absorb heat instead of reflecting it the way a clean shingle does — on a hot Kentucky summer afternoon, that difference shows up as extra heat radiating into your attic, which your air conditioner then has to work harder to offset. Removing that buildup won't replace a real insulation upgrade, but it does restore some of the shingle's original reflectivity, and it's a benefit that's easy to overlook when the conversation is only about curb appeal.
Honest Expectations
A few things worth knowing before you book.
The roof won't look flawless the second we leave.
A soft wash kills the algae immediately, but some residual staining is normal right after treatment. It fades progressively over the following weeks as rain rinses the dead organic matter off completely.
We can't guarantee algae never comes back.
Most roofs stay clean for three to five years, but heavy tree cover, a north-facing slope, or a particularly humid summer can shorten that window. Nobody can promise permanent prevention on an outdoor surface.
If we find actual roof damage, we'll say so — and send you elsewhere.
Missing shingles, soft decking, or flashing issues are a roofer's job, not a cleaning company's. We'd rather tell you honestly what we see than clean over a problem that needs real repair.
Very steep or difficult-access roofs may need special scheduling.
Ground-applied soft washing covers the overwhelming majority of homes, but unusually steep pitches or hard-to-reach sections sometimes change the approach — we'll flag that during the quote, not after we arrive.

Common questions about roof cleaning.
Will soft washing void my roof warranty?+
No. Soft washing is the manufacturer-recommended cleaning method for every major asphalt shingle brand. Pressure washing is what typically voids warranties, because it blasts away the protective granules that shield your shingles.
How long does a roof stay clean after soft washing?+
Most roofs in Central Kentucky stay algae-free for three to five years before regrowth becomes noticeable again, depending on how much tree cover shades the roof and which direction it faces.
Will the chemicals damage my gutters or landscaping?+
No — we pre-soak all landscaping and flush gutters before and after treatment, the same way we do for house washing. The solution is designed to break down safely once it's rinsed away.
Can you clean tile, metal, slate, or cedar roofs too?+
Yes. Each material gets adjusted solution strength and dwell time — metal and tile can typically handle a bit more, cedar shake needs an even gentler approach than standard asphalt shingle.
Do I need to be home for roof cleaning?+
No. The entire process happens from the ground, so as long as we have clear access to the property, most customers aren't home when we do the work.
Will my roof look perfectly clean the moment you finish?+
Mostly, but not entirely — a little residual staining right after treatment is normal, and it continues to fade over the following weeks as rain washes the dead algae off completely.
Can roof cleaning actually lower my energy bill?+
It can help. Dark algae and organic buildup absorb heat instead of reflecting it, which raises attic and interior temperatures in summer. Removing that layer restores more of your shingle's original reflectivity.
What if my roof has actual damage, not just staining?+
We'll tell you honestly if we see missing shingles, soft spots, or structural issues — that's a roofer's job, not ours, and we'd rather point you to the right call than pretend a wash fixes everything.
