When your roof has a bad looking stain, you may be tempted to try to remove it yourself since it can be quite the eyesore. Unfortunately, cleaning a roof can be difficult, which is why it is best to leave it to the professionals. Homeowners can be tempted to use a power washer to remove ugly roof stains caused by moss, algae, dirt, and debris, but it can actually cause your roof to be worse off in the end. Here are 3 reasons why you shouldn't use a power washer to clean your home's roof.
Power Washing Won't Kill Algae
If your home has a problem with algae growing on the roof, you really should treat the problem rather than just try to get rid of the visible algae. Power washing will get rid of the algae on the surface level, but won't stop it from coming back. When you do have a big problem with algae growth, there may be an issue with it growing underneath your shingles as well. Power washing will help destroy the algae located on the roof's surface, and the roots of the algae will still survive.
Power Washing Can Cause Damage To The Roof
While the shingles on your roof were designed to withstand the hard storms that can come through your area, they won't be able to take on the high pressure of water being pinpointed on a specific area. If you use a power washer, chances are likely that it will cause a significant amount of damage to the shingles, potentially causing them to break off the roof if they were already starting to deteriorate. If this were to happen, you'll need to get a professional roofer to your home to fix the damage that you caused.
Always use cleaning methods that use low water pressure, or hire a roofer that does roof cleaning. It could end up saving you money if you end up causing damage by doing the cleaning yourself.
Power Washing Can Void The Roof's Warranty
Roofs usually come with a warranty that will last for many years, which help cover materials that fail prematurely. Manufactures can tell if a power washer has been used on the roofing materials, and it can void the warranty that you have. Even if your power washer does not cause the materials to fail immediately, it could void the warranty if a big storm comes through down the road and is the final straw that causes them to break.
