6 Practical Steps to Save Your Roof from Deadly Moss

Have you ever noticed your roof turning greenish, slippery, and damp? This article will discuss practical steps on how to detect, safely clean, and prevent moss from reappearing to protect your roof from the risk of leaks.


Inspect the source of the moisture

Before cleaning, check the shaded areas, gutter areas, joints, and ridges, and any dark or consistently wet spots. This inspection is important so you don't just erase the symptoms.


Remove organic debris from leaves, dust, and soil

Moss loves organic debris like leaves and dust. So, the first step is to remove fallen leaves, clean sediment in gutters, and ensure water drains smoothly. This can prevent moss from losing its home and nutrients.


Use a surface-safe cleaning method

A common mistake is brushing too hard or spraying with excessive pressure. This can damage the roof's coating and actually accelerate the problem. If in doubt, it's best to use a professional.


Apply a regrowth inhibitor

After cleaning, moss can return if moisture and dirt remain. Therefore, take preventative measures by using a moss-safe product.


Fix your gutters and downspouts

Clogged gutters are a breeding ground for moss. So, clean them regularly, check the slope of the gutters, and ensure the water drains smoothly. Typically, when water flows smoothly, the roof surface dries more quickly, making it harder for moss to take hold.


Schedule regular maintenance

To avoid a burden, establish a simple routine: inspect the roof from the bottom every 2–4 weeks and clean the gutters every 1–3 months. Perform detailed inspections at least twice a year, especially before and after the rainy season.
