Cedar Roof Cleaning in London, Ontario

​​

Soft Wash

​ 

We begin any cedar roof cleaning project by soft washing the wood. This step ensures any algae, dirt, mildew, and mold is removed from the wood. Our soft wash unit releases an environmentally friendly solution at under 100 psi onto your surface (using pressure on any type of wood is a big mistake as it can cause irreversible damage). Once this solution has eaten away at any organic  growth, we restore the PH balance of the wood, which results in brightening.

Sanding & Shake Replacement

 ​

Once the wood has dried we begin sanding rough areas down. This part of the process is different for every project as some sections of wood need more touching up than others. Sanding is done to remove old paint and stain, areas where algae or mildew has penetrated deeply, and to smooth out splinters or any rough edges. The goal for this stage is to provide a smooth surface for oil penetration. Depending on the condition of the shakes, we may also replace some pieces in order to ensure the overall longevity of the roof. At times shakes are just too far gone when the moss or lichen penetrates too deep.

Oil Application

​

Once everything has been cleaned, sanded, and any necessary shakes replaced, we are then able to apply a boiled linseed oil product. This oil is used to rehydrate the shakes to ensure that they don't splinter, crack, or cup over time. As cedar shakes are raw wood, these oils are slowly broken down by UV rays and our application restores these natural oils. We have several different tones available, however, we most often recommend just the natural cedar look.
