What we clean
Black streaks and organic growth can make an otherwise sound roof look older than it is. The right response depends on the roof material, pitch, height, access, drainage, surrounding landscaping, and—most importantly—the condition of the roofing system before cleaning begins.
We evaluate each request before offering roof washing. Eligible roofs are cleaned with a method suited to the surface rather than the high pressure used on durable concrete. If the photos or site review suggest repair, replacement, storm damage, or another roofing-system problem, cleaning is not the correct next step.
Properties and surfaces that fit
- Eligible asphalt-shingle and other roof surfaces confirmed during evaluation
- Residential roofs with black streaks, algae, lichen, moss, or organic buildup
- Eligible low-rise commercial roofs where access, drainage, and membrane condition support cleaning
- Properties where landscaping, siding, vehicles, fixtures, and runoff can be properly protected
How we handle the job
- Review roof material, age and visible condition, pitch, height, access, drainage, nearby surfaces, landscaping, and reported leaks or storm damage.
- Confirm that washing is appropriate, explain the cleaning plan and limitations, and identify the areas included in the written quote.
- Protect surrounding property, apply a roof-appropriate cleaning method without treating the surface like concrete, and complete a controlled rinse or dwell process as the system requires.
- Review the completed work and point out staining, wear, damage, or organic growth that may change gradually rather than disappearing immediately.
Before we arrive
- Tell us about active or previous leaks, storm damage, repairs, loose or missing materials, soft areas, failed seams, or other known roof concerns.
- Move vehicles and loose items away from roof edges and downspout discharge areas when requested.
- Close windows and doors, keep people and pets clear, and make exterior water access available if included in the work plan.
- Identify sensitive plants, ponds, rainwater collection, exterior electrical equipment, and access restrictions before scheduling.
Results, limits, and conditions that may change the plan
- Washing improves eligible surfaces; it does not repair leaks, damaged flashing, missing materials, punctures, failed seams, storm damage, soft decking, or an end-of-life roof.
- High pressure is not an appropriate shortcut for roof cleaning. Some materials, pitches, heights, access conditions, drainage conditions, or deteriorated roofs may not qualify for service.
- Widespread granule loss, lifted shingles, brittle materials, structural concerns, active leaks, and failed commercial roof membranes call for roofing evaluation before cleaning.
- Moss, lichen, oxidation, discoloration, permanent staining, or age-related wear may remain or improve gradually after cleaning.
