Soft washing sprays a biodegradable cleaning solution onto the roof at low pressure. The solution kills moss, algae and lichen at the root, then the roof is rinsed gently. Nothing is blasted off, so the shingles keep their protective granules. For a typical home it costs $550 before GST.

We never pressure wash shingles. High pressure strips the granules that protect asphalt shingles from the sun and can force water under the edges. Soft washing removes the moss and algae without that damage.

Because the treatment kills moss and algae at the root, it comes back much more slowly than moss that is only scraped off. How long depends on shade and trees: roofs under heavy tree cover or on the shaded north side come back sooner.

We protect the plants and garden beds under your roofline before any treatment goes on, and we use biodegradable solutions.

Yes. Soft washing is used on asphalt, cedar, tile and metal roofs, with the mix and pressure matched to the material. Cedar roofs often cost more than the $550 standard because of the extra care they need, so tell us the roof type when you ask for a quote.
