Why it’s important to soft wash your roof and not pressure wash it.

Maintaining the cleanliness and integrity of your roof is essential for the longevity of your property. Not only does it keep your roof looking great, but it also protects your home from structural damage caused by leaks and other issues. But when it comes to cleaning your roof, it’s important to use the right technique. Soft washing is a gentle and effective way to clean your roof, while pressure washing can cause significant damage. In this post, we’ll explore why it’s important to soft wash your roof and not pressure wash it.

Roof Cleaning and Treatment

Your roof is exposed to all kinds of weather conditions, and over time, moss, algae, lichen, and other organic materials can accumulate on its surface. These organisms can lead to significant damage, including shingle erosion and rot. Regular roof cleaning and treatment can prevent this damage, extend the life of your roof, and save you money in the long run.

Soft Wash vs. Pressure Wash

Soft washing is a method of cleaning your roof using low-pressure water and specialized cleaning solutions. This technique removes algae, moss, and other debris without damaging your shingles or roof structure. Pressure washing, on the other hand, uses high-pressure water to blast away dirt and grime. While pressure washing may seem like an effective way to clean your roof, it can actually cause significant damage, including:

  1. Shingle Damage: Pressure washing can remove the protective granules on your shingles, which can lead to erosion and leaks.

  2. Water Damage: High-pressure water can force water under your shingles and into your attic, causing water damage and potentially even mold growth.

  3. Safety Hazards: Pressure washing can be dangerous, especially if you’re not experienced with the equipment. High pressure can cause injury or property damage.

Moss Removal

Moss is a common problem on roofs, especially in damp or shady areas. While it may seem harmless, moss can cause significant damage to your roof. Moss holds moisture against your roof, which can lead to rot and decay. It can also lift your shingles, causing them to become dislodged in strong winds. Soft washing is an effective way to remove moss from your roof without causing damage.

Why you should use low pressure

It's also important to note that many roofing manufacturers recommend soft washing as the preferred method of cleaning, and using pressure washing may void your roof warranty. So, in addition to avoiding damage to your roof, soft washing can also help ensure that your warranty remains intact.

Final Thoughts

When it comes to roof cleaning, it’s important to choose the right technique. Soft washing is a gentle and effective way to clean your roof, remove moss and other organic materials, and extend the life of your roof. Pressure washing, on the other hand, can cause significant damage and should be avoided.
