Green roofing is all the craze for modern homes and those with a flair for unique architecture. Green roofs are living roofing systems that feature different types of plant life, adding a natural flair to homes.
However, if you have moss, algae, and lichen growing on your roof, please be aware that these are not green roofing features. These plant organisms can cause significant damage to your roofing systems and should be removed immediately.
Today, we’ll be taking a look at how lichens can affect the roof of your home and why you should get rid of them when they first appear.
What Are Lichens?
Lichens are an organism that evolves from the interaction between algae and fungi. These plant organisms can grow on just about any surface, and not even the most aggressive hail, snow, or rain can wash them away.
They are an invasive organism that typically damages any surface on which they grow. Lichens are found in just about every type of environment, so no matter where you live, the chance of lichens growing on your roof is the same everywhere.
How Lichen Affects Your Roof
Ruins Your Curb Appeal
Lichen growths on your rooftop can create quite an unsightly image. They’ll make your roof look like it is poorly maintained and deteriorated. If you plan on selling your home, significant lichen growth on your rooftop can affect your home’s selling price.
Harm Your Shingles
Lichens can eat away at your roofing shingles and effectively remove its top layer. This will dramatically reduce your roofing shingles’ ability to protect your home from the onslaught of the elements. Lichens will also significantly reduce the color of your roof, creating uneven patches across the roofing system.
If lichen is able to grow beneath your roofing shingles, it may loosen the shingles over time and eventually cause it to detach completely. If the lichen growth on your roof is quite significant, you may lose quite a bit of your roofing shingles, which will expose the roof deck of your home to the elements.
Difficult to Navigate Across Your Roof
Trying to navigate across your roof if you have significant lichen growth can be pretty tricky. This is because lichen can hold any water and moisture that lands on your rooftop and therefore creates a rather slippery surface.
