Scaffolding was already in place as we cleaned the roof, which had a lot of biological growth and staining. It was important not to ‘over clean’ the roof as we needed to maintain the old look of the exterior, while removing growth that could have harmed the building.
We used our DOFF cleaning system to deliver a low-pressure, high-temperature clean to the building and it allowed other workmen to continue with their jobs at the site as there were no harsh chemicals or high-pressure equipment used.
We brought our own water tanks as other tradesmen needed the mains water supply for their work.
