Moss and algae? No problem, we kill it all!

While power washing may work to remove algae and mold from your tile roof in the short-term, it can breed long-term headaches such as:

• etching the surface of the tile
• cutting through sealants and underlayments
• making the tiles more porous

High-pressure and harsh chemical systems can also drastically reduce the useful life of your tile roof. Overall, pressure washing your tile roof can cause irreparable damage to your roof, especially when done by untrained persons. Pressure cleaning companies are not trained, licensed, or certified to work on or repair any type of roof. Avoid having to pay someone to clean your roof and another to repair the damages caused by the cleaner.

Here are five reasons we DO NOT recommend pressure washing your tile roof:

1. Voids tile manufacturer warranty. Any pressure over 1,200psi can cause irreparable damage to your roof.
2. Damages roof underlayment. This creates more opportunity for leaks to happen.
3. Loosens waterproofing flashings. Loose flashings will allow water to leak in.
4. Etches tile surface. Etched tile means there are deeper crevices in the tile, making it easier for algae to grow.
5. Changes the color of the roof. Your roof will start to look duller even after cleaning.
