Proper cleaning of moss off the roof also prevents blocked gutters and costly repairs. In this guide, you will learn the safest way to do it step by step.

Before you start cleaning moss off the roof, make sure you stay safe. Use a strong ladder, non-slip shoes, gloves, and eye protection. Never walk directly on fragile tiles. If the roof is steep or high, it is safer to call a professional.
Step 2: Remove Loose Moss by Hand or Brush
Start by removing moss from roof tiles using a stiff brush or long-handled broom. Work gently from top to bottom so you do not lift or crack the tiles. You can also use a small trowel for thicker areas of roof moss. Choose a dry day for this step to make getting rid of roof moss easier. Do not use a pressure washer. High pressure can strip tile surfaces and cause leaks inside the loft.
Step 3: Apply Moss Killer
After removing most of the loose moss, apply a roof-safe moss killer. This helps eliminate moss on the roof and kills small spores you cannot see. Use a garden sprayer and follow the instructions on the product. Cover plants, patios, and outdoor furniture before spraying because moss weed killer can damage them.
Step 4: Let the Treatment Work
Leave the moss killer to dry and work fully. Some treatments need a few hours, while others take several days. The solution will soak into the remaining moss on the roof and kill it at the roots. This helps prevent fast regrowth.
Step 5: Rinse Gently
If the product instructions say to rinse, use a normal garden hose. Use low pressure only. Rinse from the top down so water flows naturally into the gutters. Avoid strong water force to protect your tiles.
Step 6: Clear Gutters After Cleaning
Once you finish moss removal from roofs, check and clear your gutters. Loose moss often falls and can block drainage systems. Blocked gutters can cause water to overflow and damage walls. Keeping them clear helps protect your whole roof structure.
