Homes in areas with high humidity levels tend to struggle quite a bit with moss growth on their roofing systems. And you may be thinking; that it’s just a bit of moss and that it’s not a big deal.
However, while moss growth may look good on some fairytale cottages, in reality, it is capable of causing significant damage to your home’s roofing system and can impact the health of your family. As one of Columbia’s leading roofing companies, we’ve seen just how drastic the impact of moss growth can be on homes.
If you still don’t believe us, keep reading as we detail the causes and impact of moss growth on your roof.
The Causes
Moss is a non-vascular flowerless plant that grows in humid, damp environments. They often grow in large green clumps and spread everywhere. They can grow pretty much anywhere; all they require is surface area and moisture.
Roofing systems provide wide-open spaces for moss to spread and grow. And because roofs have small nooks and crannies, these moss growths can often go unnoticed before becoming a big issue.
You’re probably wondering how they end up on your roof in the first place? Well, moss spores are microscopic plant matter, which means they are easily transported through the air before landing on your rooftop.
Moisture is vital to their livelihood, so whenever they come into contact with any water or moisture, they soak it up to sustain themselves and encourage growth.
Now we all know, that any type of moisture on your roofing system is unwelcome. So when a plant organism is not only retaining this moisture but spreading it throughout your roof, you may encounter some significant roofing issues.
Roofing Issues Caused By Moss
Lifting Shingles
Moss can grow anywhere, even on the underside of your roofing shingles. This growth can weaken your shingles over time.
If enough moss is able to grow beneath the shingles of your roof, it will start to push up the weakened shingle, eventually causing it to lift off the roof altogether.
Rot
Moss holds on to water and moisture to survive. If moss is thriving on your roofing system, chances are it is retaining any water and moisture that comes into contact with your roof.
This stagnant water can lead to rot developing on your roof deck. Rot is the quickest way to deteriorate any material. So what once started as a little patch of green moss can lead to you having to replace your entire roof deck.
Leaks
Once the moss on your roof has developed into such a state that it has caused your roofing deck to rot, you may encounter some leaking issues in your home.
A deteriorated roof deck exposes the interior of your home to natural elements. Leaks are not only annoying, but they can significantly impact and damage the structure of your roofing system and the interior of your home.
Leaking and moisture inside your home can also encourage mold growth, affecting your and your family’s well-being.
