Can I pressure wash my roof?

We do not advise using a high-pressure washer on your asphalt shingles, as this can cause striping of granules. Similarly, pressure washing tiles will erode the finishing on the tiles.
On average cleaning, a roof should be done from after five years after it’s fitted, and you should use a soft wash system that uses low pressure. Low pressure will be less pressure on your tiles and less risk of causing a leak.
