Roof Cleaning
Refresh your roof's appearance by addressing algae, staining, and exterior buildup with a cleaning approach suited to the roofing material.
Exterior Roof Care
A Cleaner Look, From the Top Down
Your roof is one of the most visible parts of your home's exterior. Over time, moisture, shade, and environmental exposure can contribute to dark streaks, discoloration, and organic growth.
Professional roof cleaning focuses on addressing that buildup while considering the roofing material and its condition. Different roof types require different cleaning methods, so the approach should be selected for the surface being treated.
Roofing Materials
Different Roofs, Different Needs
Roof cleaning is not a one-size-fits-all service. The material, age, condition, and type of buildup all influence the appropriate approach.
Asphalt Shingles
Commonly affected by dark algae streaks and organic buildup. Cleaning methods should account for the protective granules and condition of the shingles.
Metal Roofing
Metal roofs can develop environmental grime, organic buildup, and surface discoloration. Coatings, finishes, and manufacturer guidance should be considered before cleaning.
Tile Roofing
Clay and concrete tiles require cleaning methods appropriate for their material and condition, particularly where tiles are weathered or fragile.
Other Roof Surfaces
Specialty roofing materials may require different products, equipment, or cleaning procedures. The surface should be evaluated before treatment.
Common Roof Concerns
What's Growing on Your Roof?
Roof discoloration can have several causes. Identifying the type of buildup helps determine which cleaning method may be appropriate.
- Black streaks commonly associated with roof algae
- Green algae and other organic growth
- Moss in damp or shaded areas
- Lichen attached to roofing surfaces
- Dirt, pollen, and environmental debris
- Discoloration caused by prolonged outdoor exposure
Some discoloration may be permanent or related to the roofing material itself. Cleaning results depend on the condition of the surface and the cause of the staining.
The Cleaning Approach
Why Roof Cleaning Requires Care
Roofing materials are designed to protect your home from the elements, but that does not mean they should be subjected to excessive cleaning pressure.
Soft washing uses low-pressure application and cleaning solutions to address organic buildup. For suitable roofing materials, this approach avoids relying on high-pressure water to remove staining.
The roof's material, condition, manufacturer recommendations, and surrounding property should all be considered when planning a cleaning service.

Good to Know
Frequently Asked Questions
Have questions? Here are a few things to know before scheduling your service.
What causes black streaks on a roof?
Black roof streaks are commonly associated with an algae called Gloeocapsa magma. Moisture and environmental conditions can contribute to its growth, particularly on asphalt shingles.
Can roof cleaning remove algae and moss?
Roof cleaning can address algae and certain organic growth, including moss and lichen. The appropriate treatment and expected results depend on the roofing material, its condition, and the extent of the growth. Some growth may release gradually rather than disappearing immediately.
Is soft washing different from pressure washing a roof?
Yes. Soft washing relies on low-pressure application and suitable cleaning solutions rather than high-pressure water. Excessive pressure can damage roofing materials, particularly asphalt shingles.
What types of roofs can be cleaned?
Cleaning methods vary for asphalt shingles, metal roofing, tile, and other materials. Roof condition, manufacturer guidance, and the type of buildup should be considered before selecting a treatment.
How often should a roof be cleaned?
Cleaning frequency depends on factors such as shade, surrounding trees, moisture, roof material, and visible organic growth. There is no single schedule that applies to every property.
Will roof cleaning fix leaks or damaged shingles?
No. Roof cleaning addresses exterior buildup and staining; it is not a substitute for roof repairs. Loose, damaged, or deteriorated roofing materials should be evaluated by a qualified roofing professional.
Will all stains disappear immediately?
Results depend on the material and type of staining. Some organic buildup may require time to release after treatment, while permanent discoloration or material deterioration may not be reversible through cleaning.
