Low Pressure Detergent Clean

The safe way to clean your roof, Chemwash cleaning uses very low pressure. This means the surface or paint will not be damaged during the cleaning process. The moss, mould, lichen, dirt, & grime will simply wash away, leaving a sparkling new roof. Our specially formulated products do all the hard work, not the high water pressure like most other cleaners.

Pre-Paint Clean

Painting your roof? We can help with the hard part… preparation.

Sanding flaky paint off roofs is no fun. We know this, you know this, and your back definitely knows this. We use a moderate water pressure to help blast most of that flaky paint away, without damaging the surface below.

Weather Wash Spray & Leave Treatment

Our trained professionals evenly apply our specially formulated treatment to your roof at a very low pressure. This treatment will not harm plants, pets, or people.

Due to the deliberate slow action of the treatment, it may be some time before you notice any difference. The period of time before the surface is clean will vary, but can be anything from three months to a little over a year. It depends on the existing condition of the surface, how exposed it is to the elements and the extent of vegetation shading the surface.

This treatment is guaranteed to work, we provide you with a written guarantee on job completion. This guarantee is also transferable to new owners if you are selling your home.

Gutter Cleaning

If your gutters are full of dirt, overflowing, or have grass or plants growing out of them, we can help. We have two ways we can clean out your gutters.

While a simple hand clean will do the job most of the time, this procedure will not remove any fine dirt particles. In some cases a low pressure clean is the way to go. This type of clean removes the small dirt particles, as well as mould & grime build up. Keep in mind that the downpipes will need to be disconnected from your water tank while we are performing the clean. In some cases we can do this for you, but it is best to check with your plumber to see if you have a diverter installed.

We recommend cleaning your gutters annually to prevent blockages and possible water ingress, which can lead to costly repair bills.
