A Soft Wash for your terracotta or concrete tile roof in Glen Iris means removing roof moss, lichen, dirt and pollution grime using our low pressure cleaning system. This means that we can use low pressure for cleaning roof moss and dirt from old terracotta tiles without damaging or breaking them. NOT high pressure that can blast water into your roof space during the cleaning process. Terracotta tiles do not sit snugly together like cement tiles so leaks and ceiling stains can be quite common during the high pressure cleaning process. Because our system is low pressure there is no risk at all in getting leaks or causing water damage to your ceiling.
