Why Roof Cleaning Matters

Dark streaks on a roof are often more than dirt. In many cases it’s Gloeocapsa magma, an algae that loves warm, humid places like Lexington. It shows up as black streaks, especially on the shaded sides. It can also invite moss, lichen, and mildew where the roof stays damp.

Lexington gets roughly 45 to 50 inches of precipitation a year, on well over 100 days, so a shaded roof doesn’t dry out for long. Our guide to algae, mold, and mildew in Lexington covers how they spread.

Roof cleaning, also called roof washing, removes this buildup, and most residential roofs get soft washed to do it safely. Cleaning early keeps streaks from spreading and moss from taking hold.

  • Typical cost: $600 to $1,200 for most residential roofs
  • Method: soft wash roof cleaning with a low-pressure rinse, typically under 100 PSI
  • Time: two to three hours for most residential roofs
  • How often: every 3 to 5 years for most Lexington roofs
  • Guarantee: 30 days, and we re-clean the area free if streaks or algae return

How Do You Know If a Roof Needs Cleaning?

A roof needs cleaning when something is growing on it. Black streaks usually mean algae, and they show up first on shaded, damp slopes, especially under mature trees. Green or fuzzy patches mean moss or lichen. Moss is the one to watch, since the Asphalt Roofing Manufacturers Association says it can lift the leading edges of shingles and, in severe cases, may cause leaks.

A clean roof doesn’t need washing. If the shingles look the same color all over, there’s nothing to remove, and we’ll tell you so. Algae streaks alone are mostly a looks problem, since ARMA found no scientific evidence that algae damages asphalt shingles. Cleaning them early still keeps the streaks from spreading across the roof.

Roof Materials We Clean

Asphalt shingle is the roof we work on most often in Lexington, but it’s not the only one. We change the solution and the rinse to match what’s on the roof.

Roof type

What to know

How we clean it

Asphalt shingle

The most common roof in Lexington and the most exposed to Gloeocapsa magma staining.

Soft washing removes it without disturbing the protective granules.

Tile

Durable, but algae and moss still grow in shaded areas.

A lower-pressure approach to avoid cracking or moving individual tiles.

Metal

Resists algae better than shingles, but collects dirt, pollen, and streaking.

Cleaned without the abrasive contact that can scratch a painted or coated finish.

Cedar shake

One of the more delicate roofing materials.

A gentler solution and rinse that removes growth without stripping the natural oils.

Soft Washing vs. Roof Pressure Washing

Plenty of homeowners ask us to pressure wash or power wash their roof, but most residential roofs can’t take high-pressure water the way concrete can.

Asphalt shingles have mineral granules on top that shield the roof from weather and sun, and too much pressure knocks them loose and shortens the life of the roof. The Asphalt Roofing Manufacturers Association says the same. Its guidance on algae discoloration warns that high-pressure washing is likely to damage asphalt roofing.

Soft washing matches the method in ARMA’s cleaning guidance. A cleaning solution breaks down the algae, moss, and other growth. Then we rinse with low-pressure water. It’s gentle on the surface, which is what asphalt shingles and most other roofing materials need.

High Pressure Alone

Can dislodge protective granules and shorten shingle life.

Soft Washing (Our Method)

A specialized solution breaks down algae and moss, then a low-pressure rinse clears it away safely.

Will Soft Washing Void My Shingle Warranty?

ARMA suggests cleaning asphalt shingles with a bleach solution and a low-pressure rinse, which is how soft washing works, and it says high-pressure washing is likely to damage them. Warranty rules still differ by manufacturer, and ARMA says other cleaning chemicals or methods should not be used without the manufacturer’s approval.

Check your shingle warranty before any roof cleaning, and ask us about it when you call.

Our Roof Cleaning Process

1

Roof Inspection

We inspect the roof to identify the roofing material, algae or moss growth, and any areas that need extra attention.

2

Landscape Protection & Cleaning Solution

We pre-soak plants and landscaping around the home, then apply a professional roof cleaning solution and let it dwell for 15 to 20 minutes.

3

Low-Pressure Soft Wash

We rinse the roof using a soft washing system that typically runs under 100 PSI, removing the loosened contaminants.

4

Final Inspection & Quality Check

Once the roof has been cleaned, we complete a final walkthrough to check for consistent results, inspect any remaining problem areas, and take care of any spots that need a second pass before the project is finished.

The change is easiest to see when you compare the roof before and after cleaning. Near Hamburg we cleaned a clay tile roof covered in algae, lichen, and dark staining, and near Beaumont an asphalt roof with moss and algae buildup. Streaks and growth make a roof look older than it is. You can see more finished jobs in our case studies.

Common Questions

Frequently Asked Questions

Below are answers to some of the questions homeowners and business owners ask before
scheduling roof cleaning services in Lexington.

Most Lexington roofs need cleaning every 3 to 5 years. North-facing slopes and roofs under heavy tree cover often need it sooner, since algae grows faster there. Once the roof is clean, regular upkeep keeps the streaks from coming back.

Roof cleaning is necessary when moss is growing, and it’s optional when algae streaks are the only problem. Moss holds moisture against the shingles and can lift their edges, while algae streaks are mostly a looks problem. If the roof has no growth, there’s nothing to clean and no reason to pay for it.

Homeowners can clean a roof themselves, but it’s risky. Roofs are steep and slippery when wet, and the wrong pressure or chemicals can damage them. ARMA also warns that the cleaning process itself makes a roof slippery and recommends trained professionals, so most homeowners find it isn’t worth the risk.

Most residential roofs take two to three hours from start to finish, depending on size and how heavy the buildup is.

Power washing a roof is the wrong move for most residential roofs, especially asphalt shingle, because high pressure can knock off the protective granules. ARMA says never to use a pressure washer on an asphalt shingle roof, and not to scrub it with a brush or broom either. We use soft washing, which loosens algae and moss with a cleaning solution and rinses at low pressure.

A careful roof cleaner uses a cleaning solution and a low-pressure rinse, and never a pressure washer, brush, or broom. ARMA says not to use any of those to clean algae from asphalt roofing. Ask what pressure the crew uses, how they protect your plants, and whether they’ve checked your shingle warranty.

Roof cleaning can harm grass and plants when the runoff isn’t controlled, because the solution is bleach-based. We pre-soak plants and landscaping before the solution goes on and rinse the area again afterward, and ARMA also says to protect landscaping from the solution. Our landscaping and pet safety guide explains the steps.

Algae can come back after roof cleaning. ARMA says the effect of cleaning is only temporary and the discoloration may recur, and shaded, damp slopes grow it back sooner. That’s why most Lexington roofs need cleaning every 3 to 5 years, and why algae-resistant shingles are worth asking about when it’s time to replace a roof.

Zinc or copper strips can help prevent algae and moss, but ARMA lists them as an option for a new roof and doesn’t recommend adding them to an existing one. Installing them means either exposed nails, which can leak over time, or breaking the shingle sealant bond, which may lead to wind damage later. For an existing roof, cleaning is the usual route.

Roof cleaning in Lexington usually costs between $600 and $1,200 for most residential roofs. The price depends on the size and pitch of the roof, the roofing material, how easy it is to reach, and how much algae or moss needs to be removed. Our pricing guide lists typical ranges for every service.

We clean asphalt shingle roofs across Lexington using soft washing, which removes black streaks, algae, and moss without disturbing the protective granules.
