Roof Cleaning Services in the Seattle Area
Seattle’s damp, moss loving climate is constantly working against your roof. Moss, algae, lichen and debris trap moisture against your roofing material, breaking it down over time and shortening its lifespan. Revolution Roofing provides safe, professional roof cleaning that removes buildup without damaging your shingles, protecting your home’s appearance and extending the life of your roof.

Why Roof Cleaning Matters in Seattle
Think of roof cleaning like preventative care for your home. Regular cleaning stops moss, debris and algae from trapping moisture and breaking down roofing materials before small issues become expensive repairs. Left untreated, moss buildup can shorten a roof’s lifespan by years and lead to leaks, rot, and costly structural damage. Routine cleaning keeps your roof performing and looking its best year round.
Our Roof Safe Cleaning Approach
We use techniques designed to clean thoroughly without damaging your roofing material. Aggressive pressure washing can strip protective granules and force water under shingles, so our team relies on safe, low-impact methods suited to your specific roof type, whether asphalt, TPO, PVC, or metal, to protect your investment while restoring your roof’s condition.
Our Roof Cleaning Process
Revolution Roofing has decades of experience building and caring for every type of roof. Below is our step by step process we’ll walk you through.
1. Roof Inspection & Assessment
We start with a thorough inspection to evaluate moss, algae, and debris buildup, identify problem areas, and check for any damage that may need attention before cleaning begins.
2. Debris Clearing
Our team clears leaves, branches, and other loose debris from the roof surface, valleys, and drainage pathways to improve water flow and prepare the roof for treatment.
3. Moss & Algae Treatment
We apply a roof-safe treatment designed to loosen and kill moss, algae, and lichen without damaging shingles, tiles, or other roofing components.
4. Safe Moss & Growth Removal
Using low-impact techniques suited to your roof type, we carefully remove remaining moss and organic growth, minimizing stress on the roofing material throughout the process.
5. Gutter & Drainage Check
Where included, we clear gutters and downspouts of moss and debris to help ensure proper drainage and prevent water backup after cleaning.
6. Final Walkthrough & Prevention Tips
We walk the roof one final time to confirm results, clean up the property, and share recommendations to help slow future moss and algae regrowth.
