What we can do for you
How Thomson's residential moss removal works
Every residential job follows the same three-step process and is designed specifically to protect your roof throughout, from first contact to final cleanup.
Preparation
Our technicians remove all visible moss by hand using small hand tools because pressure washers strip shingle granules and void manufacturer warranties. Gutters are cleared and the surrounding grounds are tidied before we leave.
Application
We apply Thomson's non-toxic treatment solution to the fully prepped roof surface. Completely safe for pets, children, and garden beds.
Maintenance
Your roof is guaranteed moss-free for 1–2 years after treatment, covered in writing. Thomson tracks your warranty and contacts you when retreatment is due. You manage nothing.
