Tidying drains in Adelaide is a very difficult responsibility especially when some of the properties have very steep roofs which has been very popular over the last ten years. So how can you clear up your troughs when your roof is very steep and cannot get a ladder down the sides because the yard is to tight and small. There is a great device called robot trough rinseer and it is controlled by a remote control and travels done the inside of the troughs and flicks all the debris out the sides onto the ground. These devices retail for about two hundred dollars.
If you can get means of entry to your roofs and they are not too steep then you can get onto the roof and clean them by hand, this is the cheapest ways and means and pretty much straight forward. If you are not comfortable about climbing ladders and washing drains at the same time you can hire someone to too do it there are many people who will clean your channels for around one hundred dollars. If you decide to clean the troughs yourself make sure you stay safe and have on proper foot ware for the venture and do not wear thongs on a roof its the best way to slip off.
You can go to your local hardware store and get many different types of tools such as garden blowers that simply blow the debris out of your drains, this ways and means really only works in summer when the debris is dry and light.
