Does Power Washing Damage Roof Tiles

A main concern that people have is that the hard jet of water coming from the pressure washer nozzle is too strong and will loosen or damage the shingles and thus leave the roof porous and vulnerable to rain.

Does power washing damage roof tiles.

Pressure cleaning companies are not trained licensed or certified to work on or repair any type of roof. Most techniques that we have come across to remove moss are often achieved by violent means such as power washing which may cause damage to the roof especially when combined with unnecessary foot traffic often leading to cracked or broken roof tiles. Overall pressure washing your tile roof can cause irreparable damage to your roof especially when done by untrained persons. If you have glazing on roof tiles you ll find that the color will begin to fade.

The adverse effects of pressure washing are also more visible in older roofing systems which are already naturally thinner and less granulated. Avoid having to pay someone to clean your roof and another to repair the damages caused by the cleaner. The damage is barely visible to the naked eye especially during the first wash but this damage accumulates over time. A chemically cleaned soft washed tile roof is easily evenly coated and all algae is killed and disintegrated.
