We have done another successful job at weekend. One of our customer had big issue with overflowing water over the top gutter, especially when rained heavily. We knew with our experience that we had to check a down pipe first as it has always been quite same case in the past. So we did! We checked the down pipe and found a piece of roof tail, stuck in the top of the down pipe. Everytime, when it was raining, the water floated with all the moss towards to the blocked down pipe. We pulled the roof tail out and cleared all the mud and moss out. All excess water flow out away. Job done!
