What Professional Roof Cleaning Really Involves
High pressure roof cleaning is not just about improving appearance. It is a preventative maintenance service that protects tiles, sheeting, gutters, valleys, and waterproofing systems from premature failure. A proper clean removes the biological growth, sediment, and debris that slowly break down surfaces and block drainage paths. Done correctly, it restores your roof’s function, not just its look.
Our approach focuses on safe pressure levels, targeted cleaning, and careful debris removal to avoid damage while delivering a deep, long lasting clean.
Why Our Johannesburg Roof Cleaning Method Works
Roof cleaning fails when too much pressure is used, drainage is ignored, or moss is removed without treatment. We avoid these issues by combining:
• Controlled cleaning pressure appropriate for your tile or sheet type
• Full gutter, valley, and outlet cleaning to restore proper water flow
• Moss and algae treatment to prevent regrowth
• Safety focused working methods on steep or fragile roofs
With over 30 years of experience in Johannesburg’s climate, we know how to remove dirt without damaging tiles, coatings, or waterproofing systems beneath.
If your roof needs deeper protection after cleaning, our roof waterproofing services provide long term defence against leaks.
Who Benefits Most from High Pressure Roof Cleaning
Our service is ideal for:
• Homes with tile or sheeting roofs covered in dust, moss, or lichen
• Properties surrounded by trees that drop leaves into valleys and gutters
• Older roofs needing maintenance before waterproofing or restoration
• Complexes, estates, and commercial buildings wanting preventative care
• Homeowners preparing to paint, resurface, or list their property for sale
If your roof looks dull, drains slowly, or shows dark streaks, cleaning is the first step before repairs or coatings.
Problems Roof Cleaning Helps Prevent
Many roofing issues begin as small blockages or biological growth. Regular cleaning prevents:
• Roof leaks caused by blocked valleys and gutters
• Moss roots lifting tiles and creating water entry points
• Dirt build up that hides cracks or early damage
• Corrosion on metal roofs from trapped debris
• Premature ageing of waterproof membranes and coatings
• Water pooling on flat roofs
Cleaning is often the difference between a minor maintenance job and a major repair.
Once cleaning is complete, our roof maintenance plans help keep your roof healthy year round.
Long Term Benefits of Professional Roof Cleaning
A properly cleaned roof offers more than instant visual improvement. You also gain:
• Longer roof lifespan and reduced repair costs
• Better drainage during Johannesburg’s heavy rains
• Improved performance of waterproofing systems
• Protection against moss regrowth
• Enhanced property value and curb appeal
Clients often find that regular cleaning prevents problems they were unaware of, saving thousands over time.
How Our Roof Cleaning Process Works
We follow a structured method to ensure a safe, thorough clean:
Inspect the roof for cracks, loose tiles, weak spots, or rust
Remove loose debris and leaves by hand
Apply controlled high pressure cleaning to all surfaces
Clean gutters, valleys, and drainage outlets
Treat moss and algae where needed
Perform a final inspection to confirm that water flows correctly
This process ensures your roof is both visually restored and functionally improved.
If blockages or runoff issues remain, our stormwater and drainage solutions can resolve underlying water flow problems.
Common Questions About High Pressure Roof Cleaning
Will high pressure cleaning damage my tiles or sheeting?
No. We use controlled pressure suited to your roof type, preventing surface damage.
Do you clean gutters and valleys as part of the service?
Yes. Proper drainage is a critical part of roof cleaning.
How long does a roof clean last?
Typically 12 to 24 months depending on your environment and roof materials.
Can cleaning fix leaks?
Cleaning removes blockages that cause leaks, but additional waterproofing may be needed for structural issues.
Should I clean before waterproofing or painting?
Yes. Cleaning is the first step before resurfacing, sealing, or painting.
