Moss might give your home a touch of fairytale charm, but it can be an indicator of water damage or other roofing problems — not what you need when you’re looking to live happily ever after.
So what should you do if your roof becomes covered in moss, lichen, algae, or similar growths? Do you need to replace your roof entirely, or is there an easy way to safely remove the moss and restore your roof back to its previous state? Keep reading to find out.
Does a roof with moss need to be replaced?
If you notice moss or algae on your roof, don’t panic. The presence of moss doesn’t always mean you’re destined for a whole new roof, nor does it mean your home has suffered water or moisture damage.
Moss tends to form in areas where it is shielded from the sun. If sections of your roof are under heavy tree cover, these are prime spots for moss to thrive. And if you live in a damp climate that sees a lot of rain, chances are you will notice telltale signs of algae or moss forming on your roof at some point in your home’s lifespan.
The presence of moss doesn’t always mean that your roof has sustained damage, especially if you catch it early. Like leaves in your gutters, moss is only a problem if you allow it to grow unchecked.
How do I clean moss off my roof?
If you notice moss in small sections, you should remove it. You can try to do this on your own, however, most homeowners are more comfortable hiring a professional to handle the job.
If you decide to tackle the task on your own, avoid using a power washer. Most people don’t have the knowledge or skill to prevent the spray from finding its way under the shingles. If you inadvertently force water beneath your roof’s shingles, you could end up doing far more harm than good.
A safer way is to use a mix of 50-50 water and household bleach to kill the moss. The Asphalt Roofing Manufacturers Association recommends letting the mixture sit for 15-20 minutes and then rinsing it with low water pressure. As it dies, the moss will loosen, and it’ll be easier to rinse or brush away.
What is the best way to remove moss from a roof?
In some cases, moss can cause serious damage. If your roof has been moss-covered for a long period of time, don’t attempt to remove it. Instead, contact an experienced home roofing expert for a free roofing evaluation.
If the moss has caused water damage, your roof may be too unstable to walk on or even lean against. Don’t risk your safety just to save a buck. Get a pro’s opinion before you try to clean or repair your roof.
