How Moss Removal in Your Roof Helps Prevent Roof Leaks

Moss thrives in cool, damp climates and is most likely to grow on north-facing roof areas that remain shady all day. To kill moss, use a scrub or long-handled soft-bristle brush and work in one section at a time to avoid lifting shingles.

Suppose you prefer a chemical treatment; mix and apply a moss-killing solution according to the product instructions. Position a ladder next to your garden and cover flowerbeds with plastic sheeting to prevent chemicals from spilling or dripping down into them.

Reduces Moisture

If left unchecked, moss can lead to moisture buildup and roof leaks. Moss is a non-vascular plant and can hold water in its cells for extended periods, so it can easily trap moisture under and between shingles, especially on shady portions of your roof.

To reduce the amount of moisture trapped in your roof, remove moss as soon as it appears, and keep up with routine maintenance to prevent moss from returning. To do this, work with a ladder and wear proper safety gear, including rubber gloves, slip-resistant shoes, eye protection, and a hard hat or a sturdy helmet. Work only when conditions are dry and take frequent breaks (loose moss can be a slipping hazard). For safety, and quick moss removal, hire moss removal Victoria

Prevents Leaks

Cool, shady conditions are the ideal environment for moss to grow, and it can eventually damage asphalt shingles by pulling up the granules that protect the roof. Over time, the moss can also cause cracks and leaks in the roof, so removing it before it becomes too extensive is essential.

Various commercial and homemade cleaning solutions can kill the moss and make the roof unsuitable for its growth. Choose one with the lowest toxicity level possible for the shingles and plants surrounding your house to avoid damaging them.

Prevents Damage

When moss takes hold, it grows into fissures and cracks in the roof surface. These areas retain moisture that can wreak havoc on roof tiles, shingles, and wood rafters and cause leaks inside the house.

First, rinse off the roof with a hose spraying downward to remove moss. Then apply a store-bought or homemade cleaning solution. If using a store-bought product, follow package directions. If using a DIY solution, ensure you wear protective gear when climbing on the roof (work boots, thick gloves, and safety harness) and that the ladder is secured and anchored.

To help prevent future moss growth, regularly trim trees near the roof to keep them from blocking sunlight or leaving shade on the roof. Additionally, installing copper or zinc strips on the roof ridge may deter moss growth by absorbing water that would otherwise wash it off. This may take some time to be effective, though.

Increases Roof Life

Besides making the roof look unsightly, moss traps moisture against its surface, weakening it over time. This can lead to rot and damage to the shingles. It can also make accessing the roof for maintenance and repairs difficult or dangerous.

Regular moss removal can significantly increase the lifespan of your roof, maintain curb appeal and property value, and help save on energy costs. In addition, you can reduce the likelihood of future moss growth by pruning trees that hang over the roof or installing algae-resistant shingles.
