Roof washing, however, does come with some risk of damage if it’s not done correctly. Shingled roofs are not hardy enough to withstand the harsh nature of pressure washing, which is why we only use soft washing techniques to target built-up dirt and debris on your commercial property’s roof. Using pressure washing can lead to unnecessary and costly damage that you likely won’t notice until that damage is both extensive and expensive. At Ecoclean Northwest, we have the industry knowledge to ensure that we are taking great care to get everything as clean as possible while keeping your exterior surfaces safe.
