You’re circling your home doing your usual property inspections when you spot something strange on your roof that certainly sticks out from the colour of your tiles. On closer examination you realise its some kind of green growth – no doubt spurred on by the rain. So what exactly is growing? Is it bad for your roof and should you try to clean it? This blog will help you understand what kind of growth tends to occur on roofs and what Auckland roof maintenance experts suggest you do about it.
Identifying The Growth
Not all green growth is moss – and depending on what it is, you might need to take action sooner rather than later. Here’s what to look out for.
- Algae and Moss – this usually grows on wood and in areas that don’t get much sun, as well as gutters. It will range from black to green and if left unchecked can rot wood away completely. Moss looks similar to algae and also likes moisture but prefers to stick to surface areas.
- Mould and Mildew – Mould might look like moss and algae at first, but if it starts to spread rapidly and has a foul stale odour, you’ll know it’s mould. This you should never ignore as inhaling mould can cause breathing issues, and it can quickly spread to invade every area of your home. Mildew will spread just as fast, but in areas where drainage is compromised or trees haven’t been trimmed near your roof. It tends to come in a variety of colours but will look and feel powdery.
How Do I Get Rid Of It?
Your first instinct when you spot any of the above will be to either scrub it away or blast it with water. Both are bad ideas. Unless you have the equipment to get near the area safely, you could fall and hurt yourself badly. And water blasting is a bad idea as you have no idea what condition your roofing will be in underneath the growth. A harsh blast of water could disintegrate shingles completely, leaving you with a gaping roof hole.
Getting rid of growth is a job reserved for the experts and not for amateurs. Remember – you don’t just want it gone, as you also want to prevent it from returning. Only an expert in Auckland roof maintenance is able to navigate this in a way that doesn’t leave you with a hefty bill and a destroyed roof.
