Why It Matters
Why Roofs Call for Soft Washing, Not Pressure Washing
Higher pressure removes buildup faster, but on roofs it often causes damage before it finishes cleaning — it can strip the protective granules from asphalt shingles and shorten a roof’s lifespan. Soft washing uses low water pressure with a cleaning solution to loosen algae and organic growth so it rinses away.
Low Pressure, Not Force
The cleaning solution does the work, not raw water pressure, so the roof surface isn’t blasted in the process.
Material & Access First
Roof cleaning has its own safety and material considerations. We ask about your roof’s material, pitch, and height before quoting.
Algae & Dark Streaks
Targets the algae, mildew, and organic staining that leave dark streaks and green or black patches on Katy roofs.
Care Around Landscaping
Runoff from a roof lands in beds and lawn. We take care with runoff direction near landscaping, pools, and neighboring surfaces.
Local Conditions
Why Katy Roofs Develop Streaks and Algae
Katy’s Gulf Coast climate is close to ideal for roof algae. Here’s what actually drives growth on roofs around here.
| Local Factor | How It Affects Your Roof |
|---|---|
| Gulf Coast humidity | Persistent moisture in the air lets algae and mildew take hold and spread across roof surfaces, especially on shaded sections. |
| Shade & tree cover | North-facing slopes and sections under mature oaks stay damp longer after rain and dew, so growth tends to start there first. |
| Seasonal heavy rain | Repeated wet-dry cycles during storm season keep roofs damp, which is exactly what encourages regrowth. |
| Leaves & organic debris | Leaves that collect in valleys and along the roof edge hold moisture against the surface and feed organic growth. |
| HOA curb-appeal standards | Many Katy master-planned communities have guidelines about visible exterior condition — worth checking your community’s specific rules. |
These are general regional factors, not a diagnosis of any specific roof. Shade, tree placement, and roof material on your own home still matter most.
The Details
What Roof Cleaning Covers
- Algae and dark streaking
- Mildew and green or black organic staining
- Shaded and north-facing roof sections
- Asphalt shingle and tile roofs
Roof cleaning is quoted separately from house washing, which covers siding, brick, stucco, soffits, fascia, and trim — you can request both together. Roof repair, re-coating, and leak work are not part of roof cleaning. Debris in the gutters? See our gutter cleaning page.
How It Works
Our Roof Cleaning Process
Assess
We confirm your roof’s material, pitch, height, and access, and note anything that affects how it can be safely cleaned.
Soft Wash
We apply a cleaning solution at low pressure to loosen algae and organic growth, then rinse — no high-pressure blasting.
Final Review
We do a final visual check and clean up loose debris from the immediate work area before we leave.
What Affects Your Quote
What Affects Roof Cleaning Price
We don’t publish flat-rate pricing because every roof is different. Here’s what typically factors into a quote.
| Factor | Why It Matters |
|---|---|
| Roof size | Larger roofs take more time and more cleaning solution to treat evenly. |
| Pitch & height | Steeper roofs and taller homes require more setup and care to work on safely. |
| Roof material | Shingle and tile roofs each call for a method matched to the material. |
| Amount of growth | Light streaking clears faster than heavy, long-established algae across large sections. |
| Access | Landscaping, fences, and tight side yards around the home can add setup time. |
| Services bundled | Combining roof cleaning with house washing or gutter cleaning in one visit is often more efficient than separate appointments. |
The only way to get an accurate number is to request a free quote — we’ll ask a few questions about your roof and follow up with pricing based on your specifics.
Between Cleanings
How to Help Your Roof Stay Cleaner Longer
A few simple habits can slow how quickly algae and dark streaks come back.
- Trim back branches that overhang the roof to let in more sun and air
- Keep gutters clear so water and debris don’t sit along the roof edge
- Clear leaves from roof valleys before they break down and hold moisture
- Watch shaded, north-facing slopes, where growth usually shows up first

Questions
Roof Cleaning FAQs
Do you pressure wash roofs?
No. Standard high-pressure washing is not recommended for roofs, since it can damage shingles and strip protective granules. Roof cleaning uses soft washing: low water pressure combined with a cleaning solution.
What is soft wash roof cleaning?
Soft washing uses low water pressure with a cleaning solution to loosen algae, mildew, and organic growth so it can be rinsed away, rather than relying on mechanical force. It is generally the safer method for roofs and other surfaces that higher pressure could damage.
What causes the dark streaks on my roof?
Dark streaks and green or black staining on roofs are commonly caused by algae and other organic growth, which thrive in humid climates like Katy’s, especially on shaded sections and under tree cover.
Is roof cleaning included with house washing?
No. Standard house washing focuses on siding, brick, stucco, soffits, fascia, and trim. Roof cleaning is a distinct service with its own safety and material considerations, so it’s quoted separately. You can request both at the same time.
Can you clean a two-story roof?
In many cases, yes, depending on roof height, pitch, access, and safe working conditions. Let us know your home’s number of stories and roof material when requesting a quote.
How much does roof cleaning cost?
Pricing depends on roof size, pitch, height, material, the amount of growth, and access, so we don’t publish a flat rate. Request a free quote and we’ll follow up with pricing based on your home.
How often should a roof be cleaned?
It depends on shade, nearby trees, and how quickly growth returns on your specific roof. Shaded, north-facing, and tree-covered sections typically need attention sooner than sunny, open ones.
Is roof cleaning safe for my plants and landscaping?
We take care with runoff direction near landscaping, pools, and neighboring surfaces during cleaning. Let us know about any sensitive plants or areas when scheduling.
What happens if it rains on the scheduled day?
We monitor the forecast and will reschedule if rain is expected to interfere with cleaning or make roof access unsafe.
