6 Things You Need to Know Before Getting Your Roof Cleaned

April 30, 20263 min read

If you’re thinking about getting your roof cleaned, there are a few things most people don’t realise - and getting them wrong can cost you thousands.

Here’s what every homeowner should know before booking a roof clean.


1. Where Do the Chemicals Go?

This is one of the biggest concerns - and it should be.

A proper roof clean involves applying a treatment (usually soft wash chemicals) that removes mould, algae, and lichen.

What matters is how it’s handled:

  • Runoff should be controlled

  • Gutters should be flushed properly

  • Surrounding areas like plants and surfaces should be protected

If this isn’t managed properly, it can lead to:

  • Damage to plants

  • Stained surfaces

  • Residue around the property

A professional approach includes managing runoff and leaving the property clean.

2. Does Your Roof Need Cleaning or Repainting?

A roof that looks worn doesn’t always need repainting.

In many cases:

  • Dirt, mould, and lichen are the main issue

  • A proper clean can significantly improve the appearance

Repainting may be needed when:

  • The coating has worn away

  • There is visible structural wear or damage

Cleaning is often the most practical first step before considering repainting.

3. High Pressure vs Soft Washing

The method used can impact the condition of your roof.

High pressure cleaning:

  • Can damage tiles

  • May remove protective coatings

  • Can shorten the lifespan of the roof

Soft washing:

  • Uses low pressure with a treatment

  • Targets organic growth

  • Is generally safer for most roof types

It’s worth confirming what method will be used before booking.


4. What Happens to Your Gutters?

Roof cleaning affects more than just the roof surface.

Debris such as dirt, moss, and lichen often ends up in the gutters.

If they are not cleared afterwards, it can lead to:

  • Blockages

  • Overflow issues

  • Potential water damage

A thorough service includes flushing and clearing the gutters.


5. How Long Does It Last?

A properly completed roof clean should last beyond the short term.

With the right treatment:

  • Results can last several years

  • Organic growth is reduced at the source

If growth returns quickly, it may indicate the treatment was not applied effectively.

6. The Cheapest Quote Isn’t Always the Best Option

Price can vary depending on the level of detail and care involved.

Lower-cost services may involve:

  • Limited treatment

  • Faster, less detailed work

  • Skipped preparation steps

This can lead to:

  • Reduced longevity

  • Additional costs later

  • The need for further work

Understanding what is included in the service can help you make a more informed decision.


Final Thought

A roof clean can improve the overall appearance of your home and help maintain its condition.

Before hiring a service, it helps to understand what is included and how the work will be carried out.

This can make a difference in both the result and how long it lasts.
