What we clean on Katy roofs, and how
Roofs in Katy are different materials with different limits. The method follows the material. About 46% of Katy's homes were built before 2000, so many have older roofs or have had the roof replaced.
Tile roofs
Humidity peaks near 76.8% in September and rain falls on about 104 days a year, which keeps Katy's shingle roofs damp and feeds dark algae streaks on shaded slopes.
Soft wash with water pressure kept low. Clay tile is brittle, so we test a spot first and keep weight and force down.
Asphalt shingle roofs
Black streaks are algae, and they show first on the shaded and slower-drying slopes.
Never pressure washed. A low-pressure cleaning solution and a gentle rinse, so the granules stay on.
Moss and lichen
Moss and lichen hold moisture against the roof and are harder to remove than algae.
Solution applied and left to work, then rinsed gently. Tell us what you see and we plan for it.
Valleys and debris
Leaves and pollen collect in valleys and behind vents, hold moisture and feed growth.
We clear them as part of the job.
Vents, flashing and skylights
Dirt and growth build up where water slows down around vents and skylights.
We work around them at low pressure so seals and flashing stay put.
Walls below the roofline
Dark streaks run down the wall where roof runoff falls.
Rinsed during the roof clean, and we point out anything that needs a wall wash.

Call for your exact priceWhen to clean a roof in Katy
There is no wrong month, but the season changes what we see and how long a clean lasts.
Hurricane season
Tropical storms can bring heavy rain and debris onto roofs, walls and driveways, mostly near the coast (highest risk August to September). After a storm, call us to see what needs washing.
Spring and fall rains
Rain peaks in spring and fall near the Gulf Coast and humidity is higher in the east, so algae and mildew can build on shaded roofs and walls.
Cedar pollen season
Juniper (cedar) pollen peaks around mid-January in the Hill Country and east Texas and can leave a film on cars, siding and patios.

What you get on every job
Scheduling and coverage
Do you serve Katy, TX 77493 and nearby areas?
Yes. We work across Katy, including Old Town Katy, Cinco Ranch, Seven Meadows, Grand Lakes, Kelliwood and Nottingham Country. Call with your address and we will confirm coverage.
How long does a roof clean take?
It depends on the size and pitch of the roof and how much growth is on it. We give you a time estimate when we quote the job.
What happens if it rains or a storm is coming?
We reschedule. Rain is not a problem for the solution, but wet roofs are slippery and a storm warning is a reason to move the date. We will call you.
Methods and safety
Do you pressure wash roofs?
No. Shingle makers say not to use a power washer, and tile makers set a pressure limit. We soft wash with low pressure and let the solution do the work.
Will roof cleaning fix damage?
No. Cleaning removes stains. It does not fix missing shingles, cracked tile or granule loss, and we tell you if we see any.
How long does a clean last in Katy?
Spores arrive on the wind, so growth can come back after any cleaning. It depends on shade and how wet the season is, and we tell you what to expect for your roof.
Pricing, insurance and water rules
How much does roof cleaning cost in Katy?
Typical ranges are on this page: roughly $450 – $1,900 for a typical roof. Your exact price comes from a free phone quote.
Why does the same job cost more at one house?
Roof size, pitch, how much growth is on it and how hard it is to reach all change the time and solution needed. We explain what drives your number.
Are you insured?
Yes. Ask for proof of insurance when we quote the job.
Are there water restrictions in Katy?
The City of Katy entered Stage 1 (mild) of its drought plan on Aug. 21, 2026, with voluntary cuts, and news coverage does not mention washing. Confirm the current stage with the City of Katy before service. Rules can change, so we check the current rules before we book.
