Redruth Amateur Operatic System has a set of rehearsal rooms which are over 100 years old. In recent years, we have had issues with the amount of moss growing on the roof and being dislodge and blocking the guttering causing water to flood into our neighbours properties. The roof has a surface area in excess of 600 sq.m.
David was approached for a solution to this and he suggested that the roof is scraped and a biocide used to prevent further moss build up. David explained that some companies would pressure wash the roof, but in this, that would damage the slates.
We engaged David, and once the scaffolding went up, he started, more or less straight away. We did have some bad weather, so, for safety reasons, worked around the heavier weather. The cleaning took about a week to accomplish and we are very pleased with the outcome. He also spotted a couple of issues with our guttering, he was able to remedy for us.
David has such a great work effort, neither myself, nor Redruth Operatic, would hesitate to contact him for future works. We cannot recommend him highly.
