Make Your Home Instantly Look Better with Roof Cleaning

A roof is one of the most prominent features of any house, and its cleanliness significantly affects your home’s overall appearance. Roof cleaning is an investment that instantly makes your home look better. Imagine driving up to your property after a long day and being greeted by a sparkling, refreshed exterior. That’s the power of roof cleaning!

Roof cleaning enhances the curb appeal of your property by making it stand out in the neighbourhood. A clean and well-maintained roof makes your house more attractive to potential buyers if you’re planning to sell. It also creates a great first impression for guests and visitors, leaving them with a positive and lasting memory of your home.

Safe Roof Washing Service

Our safe roof washing service completely kills and removes existing lichen, moss and algae, leaving your roof with long-lasting protection against future growths. The cleaning is done by weather action to do its natural roof cleaning process with the wind and rain. Results appear in as little as 3 months on tile roofs, or up to 12 months on heavily affected metal roofs. Once clean, your roof can keep clean for up to 3 years.

To maintain, we recommend re-application every 2-3 years or at the first sign of regrowth. This means lower costs to keep your roof clean compared to other methods that require annual visits.
