As we’ve explained in our previous articles, softwashing relies on the intricacies of carefully selected, environmentally friendly chemicals administered through low pressure hoses to strip away dirt and organic matter. This process differs to many other high-pressure cleaning methods such as the traditional pressure washing technique, which rely on the power of the jet to blast away water.
Buildings’ roofs can often become heavily soiled with organic matter that can cause structural issues and defects if left untreated. When live matter such as algae and moss infiltrate a roof and are left to grow, buildings can suffer from all sorts of conditions that affect their structural integrity.
Roofs oftentimes are made up of materials that are slightly more delicate or intricately put together than the typical render on a wall. A roof might be comprised of individual pieces of slate or equally a felt roofing system that is joined with waterproof seals.
Hard pressure washing may get rid of the organic matter on a roof, but it can also damage the roofs structure. High pressured jets will chip away slate and stone as well as peel off seals and waterproof linings. A roof that’s not waterproof is not a roof you want to have!
This is why softwashing is one of the best cleaning methods to get rid of all unwanted dirt and matter on your roof. The carefully formulated, environmentally friendly chemicals that are used work to gentle dissolve away the matter as opposed to blasting it away aggressively.
This means that not only is your roof left looking brand new, but its structural integrity is maintained and it is very unlikely that any underlying damage will be caused.
