How to Tell If Your Roof Needs Cleaning

Your roof is one of the most important parts of your home, yet it's easy to forget about until something goes wrong. Regular cleaning isn't just about appearances — it's about protecting your property from damage.

The Warning Signs

Here are the key signs that your roof needs professional attention:

1. Visible Moss or Green Growth

The most obvious sign is green moss growing on your tiles. Moss thrives in damp, shaded areas and is particularly common on north-facing roofs. If you can see moss from the ground, there's likely much more up close.

2. Black Streaks or Staining

Dark streaks running down your roof are usually caused by algae. While it might look like dirt, this biological growth can spread quickly and make your home look neglected.

3. Tiles Look Different Colours

If parts of your roof look noticeably different colours, it's often because some areas have more growth than others. This patchiness is a clear sign that cleaning is overdue.

4. Blocked or Overflowing Gutters

If your gutters are constantly blocking or overflowing, moss and debris from your roof could be the cause. This is often the first sign homeowners notice.

5. It's Been More Than 3-5 Years

Even if your roof looks okay from the ground, if it hasn't been cleaned in 3-5 years, it's worth getting it inspected. Growth can be hard to spot until it becomes a bigger problem.

Why Does It Matter?

Leaving moss and algae on your roof isn't just an eyesore — it can cause real damage:

• • Moss holds moisture against tiles, which can cause cracking in winter
• • Growth can lift tiles and allow water to penetrate
• • Blocked gutters can lead to water damage to your walls and foundations
• • A dirty roof can reduce your property's value and kerb appeal
