Reasons Why You Should Not Pressure Wash Your Roof Shingles

Roof shingles are made of asphalt and are created to withstand the forces of nature. They do well to hold up their own against the elements of nature like rain, wind, snow, hail, etc. But one thing that they are not designed for is pressure washing.

While they can withstand rain and storm, power washing will not only clean the dirt and grime accumulated on them, but will also strip the shingles of the protective composite granules of asphalt that provide your house the much-needed protection against the elements. This is why pressure washing roof shingles is never a good idea.

Damaging your shingles’ structural integrity isn’t the only damage that pressure washing will cause. There is a good chance that it will seep through the adhesive holding your roof together and cause dampness and erosion from the inside. The adhesive will lose its strength due to this reason which will only further the damage done to your roof.

Pressure washing a roof might make it look attractive for a short while, but in the long-run, it will take away years from the life expectancy of the shingles.

Primary Culprits that Cause Your Roof to Accumulate Dirt and Grim

While these do not seem that damaging, constant accumulation of these over a prolonged course of time can cause serious dirt and grime accumulation on your roof.

How to Prevent Moss and Algae Growth on Your Roof Shingles

Now you must be wondering if pressure cleaning is not a viable option, how do you clean your dirty roof shingles? Firstly, you have to focus on reducing the growth of moss, algae, and lichen on your roof. Here are some ways in which you can do this.

  1. If you have any trees which keep your roof in perpetual shade, you need to trim/prune those branches that are causing your roof to remain in shade. If your roof remains in constant shade, it is most likely to develop moss and algae.
  2. Use a leaf blower to clean out the debris on your roof periodically. Do it down the slope so the shingle placements are not damaged. Also, you need to ensure that your gutter is clean so that the debris can be drained properly.
  3. If you have any roofs above your shingle roof, ensure that there is no water drip on the shingle roof. Instead have a gutter all the way down to the main drainage. Constant dripping of water on the shingle roof will keep it moist and damp – conditions which are favorable for the growth of moss and algae.
