Moss Growing

Is it Bad to Have Moss Growing on Your Roof?

Moss growing on the roof in the Pacific Northwest may not be an uncommon sight, but according to Portland’s The Oregonian newspaper, moss growing on the roof can force expensive repairs. Especially as we head into the winter months, the wet and humid climate encourages moss growth, thriving in this environment. Moss can spread quickly across an entire roof.

While this might seem harmless or even charming looking, the dangers that moss can pose to roofs made from any material cannot be understated. Without regular maintenance and cleaning, moss can eat away at structural supports, creating leaks and outbreaks of dangerous mold within the house itself. Beyond being just an eyesore and a potential safety risk, moss-infested roofs can also drive down a home’s value.

This type of damage is particularly prone to shingle roofs, as the moss can grow beneath the shingles and force them up. Unfortunately, though, moss can grow anywhere and on any surface. Contrary to what you may have heard, shingle roofs are not the only type of roof at risk from moss. If moss is left to spread, it can accumulate enough mass to dangerously weigh down sections of the roof. Wet moss might be adding hundreds of pounds that your roof was never designed to support.

How To Remove Moss From Your Roof

  • Wet the moss by spraying with a slow-pressure spray nozzle.
  • Create a mixture of water and chlorine bleach and spray generously on the moss.
  • Let the mixture sit for around 30 minutes. The chemicals would kill the moss loosens its grip from your roof.
  • Rise the mixture with a water spray. moss would not come out immediately, but it will dry up and blow off with the wind within a few days.

Luckily, removing moss from your roof is easy. Often, it can be done with nothing more than a ladder and a hose. Be careful when cleaning off moss yourself, as moss can make surfaces dangerously slippery. Of course, the best way to protect your home from mold is to make sure that it never happens in the first place. With regular cleanings from professionals in Portland, moss won’t have a chance to get a toehold on your roof.
