Roof Streaks

Have you begun to notice black streaks covering the roof and shingles of your Sunshine Coast property? Not only are these unsightly, but it can be frustrating to invest in a roof that provides unparalleled protection from the elements only for it to be covered in black streaks, dirt and mould. 

But the question remains – what are these streaks, why do they appear and how can we get rid of them? Put simply, these streaks are mould and bacteria growth that presents itself as streaks on your roof, and if left unchecked can lead to costly repairs. Here, we will outline the causes of roof streaks and how you can prevent and remove them with the power of roof cleaning and pressure washing.

What Is Growing On My Roof?

Mould and algae are the most common causes of streaks and stains on roofs. The organic growths may also appear as a stain or in a streaking pattern.

Like mould and bacteria found elsewhere, the mould and algae on your roof grow and thrive in dark, moist environments. Warm and humid conditions are common on the Sunshine Coast, creating the perfect environment for these pollutants to grow.

But, how does this get on my roof? Most often mould and algae are spread through the wind and rain. Similarly, various animals can also carry spores that will land on your roof.

Both of these organisms can cause extensive damage to your roof and lead to the need for costly repairs. Mould and algae retain moisture and can cause your roof to rot and decay.

How Can I Prevent Growth?

While prevention is not 100% guaranteed there are a number of solutions that can help protect your roof from damaging and unsightly growth. One such method is regular roof cleaning and maintenance, as this helps prevent growth in its tracks and increase the lifespan of your roofing. This includes:

Removing Debris

As previously stated, mould, algae and bacteria thrive in moist environments. A build-up of organic debris on your roof only serves to create the perfect place for these organisms to grow 

Make it a habit to remove any leaves, branches or other types of debris from your roof on a regular basis. This will help keep moisture levels down and prevent the growth of harmful mould and algae.

Pressure Cleaning

If your roof is already home to streaks and stains, professional pressure cleaning may be the best solution. Power washing with a commercial grade pressure washer can remove years of built-up mould, algae and dirt.

Soft Washing

For roofs with delicate surfaces, or if you want to avoid any damage that may be caused by pressure washing, soft washing is a good alternative. Soft washing uses low-pressure water and biodegradable detergents to remove mould and algae without damaging your roof.

Painting

If your roof is covered in extensive mould and algae growth, painting may be the best solution. Painting your roof will help to seal it and protect it from further damage.
