Our honest advice? This is one project you should not “DIY”. Aside from the obvious inherent danger in cleaning a roof without the proper safety equipment, there’s also a high risk of damaging your roof in the process.
Inexperienced pressure washers can destroy shingles with even a low pressure wash. Tiles can be damaged or cracked by walking on them. Roof cleaning chemicals can damage plants as well as your roof if applied incorrectly.
While we’re all for DIY home projects, this is one project we recommend leaving to the professionals. Our moss treatment process has been honed through years of experience and will leave your roof (and yourself) damage-free.
Our completely biodegradable moss treatment is applied from ladders using a sprayer to coat the moss.  It’s effective and safe. So save the DIY for your other home projects and let us take care of your roof moss.
