With the Lower Mainland’s wet climate, moss is abundant. It may look fuzzy and innocent, but those green, fuzzy clumps can lead to costly repairs or even irreparable damage. If you notice moss growing on your roof tiles or shingles, the sooner you deal with it, the less costly it will be.
While some companies offer moss removal through power washing, we disagree with this method since it can lift the shingles and cause water damage to the underlayment. Instead, we offer hand-brushed moss removal and suppression treatments to remove the moss and suppress its return.
How Moss Damages Your Roof
Since moss spores spread through the wind and needs just a little moisture to thrive, moss can grow rapidly on your home’s roof. Once moss has settled into the crevices of your roof’s tiles or shingles, it acts like a sponge, absorbing up to 25 times its own weight. Through capillary action, this moisture is soaked in by your roof’s felt underlayment. Eventually, this can causes wooden roof trusses to rot or mould to form in your home’s attic.
Preventing Moss Growth
By adding zinc or copper flashing to your roof, you can help prevent future moss growth. These metals slowly dissolve, which aids in killing moss each time it rains.
