Northwest Pro Wash | Roofing Services in Mountlake Terrace, WA 98043

Regular solar panel cleaning does double duty for your Mountlake Terrace home. While it boosts your system's energy efficiency by removing pollen and grime, it also allows us to inspect the surrounding roof area. We can spot early signs of the algae stains common here or check the condition of flashing and seals near the panel mounts, helping prevent minor issues from becoming major leaks.

While our professional soft wash treatment effectively removes existing black algae streaks, the damp, shaded conditions in our area mean stains can slowly return over time. We use preventative treatments that help inhibit regrowth for much longer than DIY methods. For lasting protection, we recommend a maintenance schedule tailored to your home's specific exposure to shade and moisture.

Absolutely. A key part of our solar panel cleaning service is a visual inspection of the roof area we're working on. We look for telltale signs of flashing failure common in our climate, such as cracked sealant, corrosion, or lifted metal around vents, chimneys, and the panel mounting points themselves. If we spot a potential issue, we'll provide you with a detailed description and recommended next steps to protect your home.
