Perhaps you have noticed some moss popping up on your shingles and wondered if you should do something about it. Yes, you most definitely should! Moss can cause substantial damage if left alone.

How Moss Damages Your Roof

As the moss grows on your shingles, it gets thicker and denser. This dense moss can harm your roof in several ways:

  • Moss absorbs moisture and starts to root itself to the roofing, which can deteriorate the shingles and the underlying sheathing. The roots may lift up the shingles, allowing water to run under them. This can lead to rot, holes and, eventually leaks. Wind can also catch the edges of the lifted shingles and damage them.
  • As moss builds up on the roof, it can catch debris, such as leaves and twigs, which in turn traps water that can result in deterioration.
  • The moss is very absorbent. It acts like a sponge, soaking up rain water. This water can make its way into and under the shingles and to the wood beneath the shingles. Over time, mold can grow and the structure will decay.

How to Remove – and Prevent – Moss from Growing on Your Roof

Cleaning the moss off of your roof is a job best left to the professionals. Regular pressure washing can damage your shingles. If you don’t pressure wash the correct way, using the right PSI you could harm your roof more than the moss itself would. So, you don’t want to attempt to power wash the moss away on your own. If you hand-scrub the moss away to harshly, you can also do substantial damage to the shingles. Additionally, moss can make a roof quite slippery to walk on, making it a dangerous DIY job. It is better to let a professional roof cleaning company tackle the moss.

To help prevent moss from returning to your roof, we recommend the following tips:

  • Cut back overhanging trees to prevent debris and water from collecting on the roof top.
  • Maintain your gutter system so that the water can properly drain from the roof.
  • Install gutter covers to keep debris out.
  • Get a Roof Shampoo, and after the service have a stain prevention treatment applied yearly.
