Roof washing in Auckland is just one of our cleaning services and we do it because it’s such an important job. Of course, once we’ve worked our magic up there, it makes the roof look so much better. But a regular roof wash is also vital in protecting the entire structure against the damage done by moss, lichen, and mould.
Let’s take a closer look at what happens when moss accumulates on a roof. It can be very harmful in a number of ways. For example, when something grows on your roof it is going to stop rain having a clear run down to the gutters. The more this water is held up, the greater the level of moisture that will collect in your roof, wear away at the roofing material, and eventually make its way inside your home. Moss is notorious in this regard as it grows very thick and it becomes like a patch of grass on your roof, giving it the ability to soak up a surprising amount of excess moisture. This can lead to a lot of damage down the track.
Moss grows something known as rhizoids which are root-like structures that help the plant grip to the surface it is growing on. If that surface happens to be the roof, then rhizoids can find their way under your tiles and make them warp, shift, or even crack. Plus, moisture that is held by lichen or moss can freeze in cold weather and cause cracks in your roofing.
The moisture trapped by moss and lichen also promotes the growth of mould inside your home. When any growth like moss and lichen builds up on your roof over a period of time, there’s a risk of exposing your rafters and other wood to moisture, which becomes a breeding ground for mould. As a dangerous airborne fungus, mould is one of the biggest causes of respiratory problems in New Zealand but it often does a lot of harm without people realising it. This is why regular roof washing is so important.
