Roof Washing in Woodbridge, VA – Algae, Moss & Lichen Removal on 1978 Shingle Roof

This roof washing project in Woodbridge, VA involved restoring a shingle roof that had never been professionally cleaned since the home was built in 1978. Over the years, the roof had developed heavy buildup of algae, moss, and lichen—common issues in shaded environments where moisture is retained. Surrounded by mature trees, the property experienced limited sunlight, creating ideal conditions for organic growth to thrive and gradually deteriorate the roof’s shingle granules.

The homeowner, who originally designed and built the home, took great pride in maintaining the property and wanted to preserve its integrity rather than pursue a costly roof replacement. After a thorough walkthrough, our team explained the soft wash roof cleaning process, including how we protect landscaping from runoff and overspray.

On service day, we began by removing debris such as branches and leaves before bagging downspouts to safeguard surrounding vegetation. Due to the home’s unique roof layout with multiple elevations and angles, the cleaning process required careful planning and execution. Our technicians applied a professional-grade soft wash solution to eliminate Gloeocapsa magma, moss, and algae while continuously rinsing and protecting the landscape.

After allowing the treatment to dwell and naturally break down organic growth, we returned for a follow-up visit to spot treat any remaining areas. The final results restored the roof’s appearance, eliminated black streaks, and extended the life of the shingles—saving the homeowner from premature replacement.
