The Dangers Of Pressure Washing Your Roof

While a pressure wash of your roof can leave you with sparkling clean shingles, youll also be left with a weaker roof system. This is especially true for asphalt roofing. Pressure washing strips away granules from the shingles, which is problematic.

These granules enable your roof to stand against the elements like harsh wind, rain, and sunlight. High-pressure washing systems dislodge these protective granules in large quantities.

The damage is barely visible to the naked eye, especially during the first wash, but this damage accumulates over time. The adverse effects of pressure washing roofs are also more visible in older roofing systems, which are already naturally thinner and less granulated.

If you have glazing on roof tiles, youll find that the color will begin to fade.

Aside from the damage it causes, pressure washing might not even be as effective as you think. Only the top layer of algae is removed in pressure washing. You get a clear finish, but the spores remain undisturbed inside the porous tile.

The effects of pressure washing will not only harm your roof it will also put a heavy dent in your pocket. The roof is one of the most expensive parts of your home when it comes to replacement or repair.

You also dont want to suffer the consequences of leaky roofs or exposure to the elements.
