Here’s where many homeowners go wrong: assuming that faster is better. Pressure washing may deliver quick visual results, but it often comes with hidden costs—like dislodged tiles, cracked pointing, and water being forced under the tiles.
Steam roof cleaning, while slightly slower, is far safer and far more thorough. It also tackles the cause of the problem (biological growth), not just the symptoms (stains).
Would you rather have a roof that looks clean for a few weeks, or one that stays clean for years?
