Roof Cleaning - Roof Washing Galveston - No Pressure, Residential Cleaning

Roof Washing in Galveston - Have you seen those black streaks on your roof? Those streaks are caused by an algae called Gloeocapsa Magma. This algae travels through the air from roof to roof and causes the staining you may have on your home. Your roof can look new again with an application of specialty cleaner and VERY low pressure rinsing.

We know exactly what causes this staining, and more importantly, how to safely remove it from your roof.  Our pressure cleaning services have cleaned 100's of roofs in the Houston and Galveston area and are the only pressure washing company in Houston/Galveston TX area to offer a 365-day, no streak guarantee. The discoloration is simply a form of algae called “Gloeocapsa Magma”. This algae is rapidly spreading in the area because of our hot and humid climate. It thrives off of the limestone that’s present in the shingle grit. You will normally notice that the staining starts either under a tree or on the north side. It doesn’t take long for it to engulf your entire roof. Not only does this roof stain look ugly, it’s robbing years of life from your roof!

Since this algae attacks the shingle grit, the grit comes off much easier. That’s why it’s very important to never allow anyone to pressure wash your roof. Pressure washing will remove the staining by removing the grit! Our system uses NO pressure – it’s just as safe as a moderate rain fall. Our system generates less pressure than a garden hose, so you can be sure that we won’t use excessive pressure. 

We don’t use high pressure sales or scare tactics. However, we do want to keep you informed of dangers and possibly prevent you from any troubles with your homeowners insurance policy. We’ve heard of some homeowners receiving letters of cancellation for their insurance policy if their roofs are not cleaned. Roof replacement is extremely costly of insurance companies – and they realize that a dirty roof leads to a premature roof replacement.

We can help! If you receive one of these letters, let us know. We’ll arrange our schedule to get your roof cleaned safely and effectively before your policy cancels. Ideally, we can take care of your roof cleaning before you ever receive a letter.

If your roof has streaks, stains, or discolorations and you want to add years back to the life of your roof, or if you just want it to look like a brand new roof, give us a call. We’ll come out, give you a free, on-site consultation and provide you with a free written estimate. Call or text us today at (832) 248-2131 or email us at
