It is common practice to hire someone to clean the interior of your home, but many people do not realise that it is just as easy to arrange for their roofs to be professionally cleaned. Roofline’s expertise in transforming the look of your roof comes from many years’ of experience and we offer a fast, safe and effective service, removing unsightly moss, algae and lichen at surprisingly low cost.
Why Clean Your Roof
A complete new roof is probably one of the most expensive outlays for a homeowner, so it makes sense to properly maintain yours, thus extending its lifespan. Indeed there are several very good reasons why you should keep up with the maintenance of your roof, some of which you may not be aware of.
Firstly, an untidy roof, covered in green and yellow moss and lichen or black algae, ruins the appearance of a house and may well detract from its market value. You can decorate the exterior of your home and spend a fortune on your grounds but it will never really look the part if the roof is unsightly.
Plus, Real estate agents may well recommend a clean before a property is put on the market. After all; first impressions count. And the longer you leave the job the more difficult it will become and the more it is likely to cost.
Secondly, there are a number of technical reasons why you should consider investing in cleaning. Moss and lichen can spread quickly and stealthily, depending on the local conditions, such as tree shade, humidity and position in relation to the sun. Although the plants do not actually attack roof tiles themselves they can hold water against the surface and create an environment that leads to the roofing material becoming more porous and, hence, more susceptible to rain erosion over time.
One of the main problems with moss, in particular, is that it can accumulate in the various rain channels on the roof and lead to poor drainage and gutter overflows. The consequence of this is often water running down the walls of the house, which can lead to a whole new set of potentially expensive problems. The growth also inhibits the reflective quality of a roof and can lead to higher air-conditioning bills.
How the Work Is Done
The process is done in three main stages, the first of which involves treatment using a special, biodegradable sterilising solution.
Mosses, lichens and algae are most commonly spread when their spores are transferred to the roof by the wind or by birds and other animal life landing on them. Simply scraping or washing the growth off with water would fail to remove these tiny spores, which become thoroughly embedded in roof materials such as terracotta tiles made from natural clay and, therefore, more porous than most other types of roof construction. The Roofline roof cleaning solution effectively kills these spores and retards any future growth; is environmentally friendly, and won’t harm pets or damage the exterior of your house.
The second stage involves pressure-washing, which is carried out with extreme care using specialised equipment. There is a fine line between clearing the moss and lichen and causing secondary damage through over-saturation, or damaging tiles by allowing powerful jets of water to force their way beneath them. Our well-trained and experienced tradesmen know precisely how much pressure a roof can withstand, and know how to work on a roof without damaging it during the cleaning process.
The third and final stage consists of rinsing down the roof and surrounding areas to remove excess chemicals, sweeping up any debris, and clearing disturbed moss and lichen any gutters and downpipes impacted by the cleaning process.
How to Prevent Your Roof Getting Dirty
If your home is surrounded by trees that cast a shadow on your roof, it is a good idea to have them thinned, if at all possible, as moss finds it almost impossible to grow in bright sunlight.
You may be tempted to clean the roof yourself, but this is a hazardous task for the amateur. Not only are wet roofs extremely slippery and potentially highly dangerous, but there is also a very good chance you will crack tiles with your feet.
