by | May 14, 2025

Remove moss on roof mistakes can lead to costly repairs, voided warranties, and even safety hazards. Moss might seem like a cosmetic problem, but it’s a serious threat to your roof’s integrity, especially in BC’s damp climate. These mistakes are surprisingly common among homeowners who attempt to tackle moss removal themselves without the right knowledge or equipment.

In this guide, ClearView Home Services reveals the top 5 remove moss on roof mistakes BC homeowners make—and how you can avoid them by using the right methods, tools, and services.


Remove Moss on Roof Mistakes #1: Using High-Pressure Washing

One of the biggest remove moss on roof mistakes is using high-pressure washing to remove moss. While it may appear effective at first glance, high-pressure washing can strip protective granules from shingles, dislodge roofing materials, and open pathways for water infiltration.

This mistake often results in long-term roof damage, leading to costly repairs or early replacement.

Better Approach: Use a soft wash method that applies eco-friendly moss treatments using low pressure. This gently removes moss while protecting your roof’s structure.
