Tile Roof Cleaning & Moss Removal

Before and after a tile pressure wash

At Northwest Roof Maintenance, we specialize in Tile roof cleaning and repairs to help maximize the life of your roof. That being said, we want to make sure that you have as much information as you need to make an informed decision for the care of your roof. Below you will find information on the different cleaning options for your tile roof. 

The method of removing moss from your tile roof will depend on a couple of factors such as the amount of moss on the tile roof, and the condition of the roof.

In cases of light moss or loose debris, all that’s needed is a powered blower to break up and remove the moss off of the roof. We generally recommend following this with a preventative treatment to stop future moss growth. If the moss is heavier, it might require an additional method – brushing.

Both powered blower and brushing methods remove moss, but will not necessarily clean the dirt and dinginess off of your tiles. If the roof is in good condition and the tiles are not brittle, we offer a pressure wash. As this is the most abrasive method of roof cleaning, we reserve this option only for the most extreme cases, or as required by HOA regulations or homeowner preference.

Customer Reviews

Rating: 5/5 ⭐⭐⭐⭐⭐

“I was referred to NW Roof Maintenance by another roofer who doesn’t work on tile roofs. Ruben just came out to give me an estimate for attic ventilation for a small mold issue. He was very thorough and knowledgeable and I appreciated his honesty when it came to the fact that he didn’t think I actually needed any more ventilation. He also told me what to watch out for in the future as our roof ages. We’ll definitely be using them when the time comes. If all of their employees are of the same caliber as Ruben, I look forward to excellent service.” -Nunya B. on Google
