IMPROVE THE LOOK AND EXTEND THE LIFE OF YOUR ROOF WITH THE THOMSON ROOF TREATMENT SYSTEM

The build-up of moss, lichen and other growth can cause severe damage to your roof. Thomson Roof Treatment is a unique company that uses an environmentally friendly solution to eliminate harmful growth.

Thomson's moss control program begins with an initial treatment to bring the roof to a growth free state by manually removing 70% of the growth then treating it with our non-toxic, soap-based solution which neutralizes the remaining moss, lichen, mould or mildew. Any residual, treated, dead growth will turn from green to greenish-brown and some or most will be washed away by rain over the following 8 to 12 months.

We do not use a pressure washer which is potentially damaging and ineffective over the long term. Our treatment is suitable for both residential and commercial buildings and is effective on cedar, asphalt, fibreglass, tile, tar and gravel roofs.

Thomson Roof Treatment originated in Vancouver in 1937 and was established in Victoria in 1980. Since then we've treated over 10,000 roofs.
