Commercial Roof Cleaning Services in St. Charles, MO

This project took place in St. Charles, MO and involved preparing a metal commercial roof for a silicone roof coating. Exterior Cleaning Solutions STL worked alongside Schneider Roofing, handling the cleaning and prep work that they require for their commercial coatings. Our role was focused on cleaning and surface preparation so the coating could be applied correctly.

The metal roof showed several issues when we arrived. It had sprung leaks in various places, and the surface was covered in years of organic growth and grime. Those conditions make routine maintenance difficult and they reduce the likelihood that a coating will adhere properly, so thorough cleaning was necessary before any coating could be installed.

We used our established soft wash methods to remove the accumulated organic material and surface dirt. The soft wash approach allowed us to clean the metal panels without harsh pressure that can damage seams or fasteners. Years of grime and biological growth were lifted from the roof, restoring a cleaner surface and exposing areas that needed repair attention.

Because this project was a prep for a silicone roof coating, attention to detail was important. Cleaning was performed in coordination with Schneider Roofing so they could assess the leaks and plan repairs before coating. We always document the condition we find and communicate visible issues, such as the sprung leaks on this roof, so the roofing contractor has a clear path forward.

Beyond preparing the surface for coating, the cleaning itself serves as maintenance for the metal roof. Removing biological growth and grit reduces ongoing deterioration and helps the roof system perform more predictably while the coating work is scheduled. For commercial coatings, that preparatory step is critical to achieve the expected lifespan and performance of the product.

This job illustrates how coordination between roof cleaners and roofers improves outcomes. Exterior Cleaning Solutions STL performs these prep services regularly for Schneider Roofing, supports that same collaborative workflow in St. Charles, MO. Cleaning, documenting roof condition, and handing the project back to the roofing contractor keeps the coating project on track.

If a metal roof shows leaks, heavy soiling, or long-standing organic growth, starting with a professional soft wash and a clear report of findings is the right next step. In this case the roof was cleaned and prepared for Schneider Roofing to move forward with the silicone coating and any necessary leak repairs.
