No surprises, straight answers
No, soft washing is the method the shingle industry actually recommends for cleaning asphalt roofs. It's high pressure that voids warranties, because it strips the granules off. We use low pressure and let the cleaning solution do the work, so the shingles and your warranty both stay intact.
We stay off the shingles as much as the job allows, and we never walk a roof that's wet. Wet shingles are slick and a boot grinds the granules loose. When a slope can only be reached safely from up top, we step carefully on dry shingles and let the chemistry travel from there, so the granule layer takes as little wear as the job allows.
If it's Gloeocapsa algae, which is the usual cause, then yes, the soft wash kills it and the streaks fade as it dies back. Heavy moss or lichen dug into a shaded valley can keep lightening for a couple weeks after we leave; that's the growth still dying, not a spot we missed.
Yes. We soak every bed and shrub under the gutters before we start and keep them wet the whole job, then rinse them again at the end. The cleaning solution only burns foliage if it's left to dry on it, and we make sure that never happens.
Best to keep them indoors during the wash and for an hour or two after, mostly so they're not drinking from puddles. Diluted, the solution breaks down to basically salt and water, but until the runoff has dried off, inside is the safe place for them.
We flush it. As we rinse, we keep the runoff moving through the gutters and downspouts and off the siding, and we rinse the beds it passes through. Nothing's left to dry on your roof, your walls, or your landscaping by the time we pull out.

Getting your quote, step by step
Four steps from the first message to a straight roof price, and a tech reads the shingles before anybody quotes you a number.
Call or fill out the form and tell us what you're seeing. Black streaks down the shaded slope, moss in a valley, a whole lake-side pitch gone green. That's all the booking team needs to get you started.
Someone reaches back fast, often the same day, and locks in a time that works for you. No phone tag, no waiting around for a callback that never comes.
Before any water runs, a tech reads the roof from the ground with you. How the shingles are holding up, which slopes face north or the water and stay damp, where the streaks run heaviest, and whether moss or lichen has settled into a shaded valley and will need extra dwell. No walking a wet roof to do it.
The tech sizes up your actual roof and gives you a straight price on the spot, free, no obligation, no trip fee. Give the go-ahead and we get to work.

Questions, answered
No, and any roof company that offers to should worry you. High pressure strips the granules off asphalt shingles, shortens the roof's life, and can void the shingle warranty, and the algae grows back quicker on a bare roof. We soft wash instead: low pressure and a cleaning solution that kills the streaks at the root, safe on the newer shingles all over Lexington.
They're a roof algae called Gloeocapsa magma, and the humidity rolling off Lake Murray feeds it. Worst on the shaded, north-facing, and lake-side slopes that stay damp. The soft wash kills it at the root and the streaks fade as it dies back. Heavy moss or lichen tucked in a shaded valley can keep lightening for a couple weeks after, which is normal.
Most Lexington roofs do well with a wash about every year-and-a-half to two years. The shaded and lake-facing pitches down off Old Cherokee and Corley Mill hold moisture longer and green back up a bit sooner, so those sometimes want it a little more often.
Over time it tries to. The spores are in the air all around the lake, so nobody can promise it never returns. But killing it at the root means it comes back a lot slower than if it were just blasted off the top, and a steady soft wash on a regular rhythm keeps it from building back up the way it did before.
Not when it's done right. We soak every bed and shrub before we start and keep them wet the whole time, then flush the gutters and rinse the runoff at the end. The solution only causes trouble if it's left to dry on foliage, and we don't let that happen.
We do. All over Lexington and Lake Murray country, from Gardendale and Kings Grant to Harbor Side, Coventry Woods, and the neighborhoods off Old Cherokee and Corley Mill. We come to you with no trip fee, and if you're right on the edge of the area, reach out anyway.

Roof Cleaning in Lexington, Lake Murray country
Those dark streaks running down the shaded side of your roof aren't dirt. They're a living algae called Gloeocapsa magma, and the muggy air coming off Lake Murray feeds it all season. It settles worst on the north slopes and the lake-facing pitches where the shingles never fully dry out, and once it takes hold it spreads. The instinct is to grab a pressure washer, and that's the one thing you can't do to asphalt shingles. The force tears off the granule layer that protects them, can void the shingle warranty, and the streaks just come back quicker on a stripped roof. With so much of Lexington being newer construction, that granule layer is worth protecting. So we soft wash instead: a cleaning solution that kills the algae down at the root, time to let it work, then a light rinse. The streaks fade as the growth dies off, and where moss or lichen has dug into a shaded valley it'll keep lightening for a couple weeks after we leave. That's the organism still dying back.
Lexington sits on the south shore of Lake Murray, and all that lake humidity is hard on exteriors. North-facing siding, shaded roofs, and pool decks green up fast from the dam down through the neighborhoods off Old Cherokee and Corley Mill. It's also one of the fastest-growing towns in the state, so there's a lot of newer vinyl and builder-grade brick that does best with a gentle soft wash rather than high pressure.
We bring our roof cleaning to Harbor Side, Indian Pines, and Barr Crossing and the rest of Lexington, with the same crew and the same care.
While we're at your Lexington place, we can knock out your house washing, brick cleaning, and window cleaning too, all on the same trip with no second trip fee.

Our process, step by step
Here's the whole run on a shingle roof around the lake. Soft wash from the first drop to the last rinse, no pressure on the shingles, and we stay off the roof as much as the job allows.
Before we touch it, we look the roof over, where the streaks run heaviest, which slopes face north or the water and stay damp, and whether moss or lichen has settled into the shaded valleys. We don't walk wet shingles to do it; a roof gets slick and a foot grinds granules loose. On newer builds the shingles are in good shape, and we keep them that way.
Every bed, shrub, and strip of grass under the roofline gets a heavy drink and stays wet the whole job. The cleaning solution is rough on foliage only if it's left to dry on it, so this isn't optional. It's how your plants and the beds under the gutters come through untouched.
We put the solution on at low pressure, even across the shingles, and give it real time to dwell. That dwell is the difference between rinsing the green off the top and actually killing it down in the granule bed. Kill it at the root and it comes back slower. No pressure ever touches the roof.
A soft rinse carries the dead growth off, then we flush the gutters and the runoff so none of it dries on the siding or the beds. Heavy moss in a shaded valley keeps lightening for a couple weeks after we go. That's the lichen still dying. We don't leave until the streaks are clearly fading.
