Roof Renew is a specialized cleaning and restoration system designed to address common roof problems without replacement. It typically consists of a cleaning solution followed by a protective treatment that aims to remove unsightly stains and growth while providing ongoing protection against future contamination. The product is most commonly used on asphalt shingle roofs, though variations exist for different roofing materials.
The formula is advertised as eco-friendly and non-toxic, making it safe for surrounding plants and landscaping when properly applied. Unlike harsh bleach solutions, Roof Renew claims to clean without damaging the structural integrity of roofing materials, which is a common concern with DIY roof cleaning methods.
How Roof Renew Works
The Roof Renew process typically involves a two-step application. First, a cleaning solution is applied to kill and loosen organic growth including moss, algae, and lichen. This initial treatment breaks down the biological matter that causes discoloration and deterioration. Depending on severity, light pressure washing may follow.
The second step involves applying a protective treatment that creates a barrier against future growth. This treatment is designed to change the pH level of the roof surface, making it inhospitable to new spores while not affecting the roof’s ability to shed water properly. The entire process typically takes one day, with full results visible within a few weeks as rainfall helps complete the cleaning process.
Application Process
- Inspection and assessment of roof condition
- Protection of surrounding landscaping
- Application of cleaning solution
- Gentle removal of persistent growth (if necessary)
- Application of protective treatment
- Final inspection

Customer Reviews and Ratings
Analysis of hundreds of online reviews shows Roof Renew generally maintains a positive reputation with an average rating of 4.2/5 stars across major review platforms. The majority of customers report satisfaction with both the process and results, though expectations management seems key to customer satisfaction.
Positive reviews frequently mention the professionalism of application teams and dramatic before-and-after results. Many reviewers share photos demonstrating the removal of black streaks and green patches that previously marred their roof’s appearance. Long-term customers who have had treatments several years prior often comment on the durability of results.
Critical reviews most commonly cite concerns about longevity, with some customers reporting algae return within 1-2 years in particularly humid climates. Others mention inconsistent results, particularly on heavily damaged roofs or those with extensive moss growth that may have already caused underlying damage.

Value assessment in reviews generally indicates high satisfaction with the cost-to-benefit ratio. Homeowners particularly appreciate avoiding the disruption and expense of replacement when their roof is structurally sound but aesthetically compromised. Several reviewers mention how the treatment improved property value prior to sale, making it a worthwhile investment.
Warranty periods average 3-5 years, though this varies by service provider. Some companies offer tiered pricing with premium options including longer warranties or maintenance plans. Customer reviews suggest that these premium plans may be worthwhile in regions prone to heavy rainfall or high humidity.
Comparison with Competitors
When compared to similar roof restoration products, Roof Renew generally ranks favorably in terms of effectiveness and value. Competitors like Roof Shampoo, Roof-A-Cide, and Moss B Ware use varying approaches to address similar issues, with each having particular strengths and limitations.
Based on comparative reviews, Roof Renew appears to have a more balanced approach between immediate cleaning and ongoing protection than some alternatives that focus primarily on one aspect. Users who have tried multiple products often comment that Roof Renew provides more consistent results across different roof types and environmental conditions.
The main differentiator noted in reviews is Roof Renew’s focus on both cleaning and protective treatment, while some competitors offer only one component. However, some competing products receive higher marks for longevity in particularly challenging environments.
Application Process and Results
Professional application is strongly recommended in reviews, with DIY attempts frequently cited in negative reviews. The application process typically starts with a thorough inspection, followed by preparation of the surrounding area to protect landscaping and exterior features from overspray.
Most customers report minimal disruption during application, with the entire process typically completed in 4-8 hours depending on roof size and condition. The initial results are usually visible immediately after application, with the full cleaning effect developing over the following weeks as rainfall helps complete the process.
Before and after photos shared in reviews demonstrate significant improvements, particularly in removing black streaks caused by algae (Gloeocapsa magnocytis) and green moss patches. The restored appearance typically includes improved color uniformity and elimination of visible growth, though reviews note that results are most dramatic on roofs that haven’t been severely damaged by growth.
Long-Term Effectiveness
For long-term effectiveness, reviews from customers who have had Roof Renew applied several years prior provide valuable insights. The consensus indicates that results typically last 3-5 years before reapplication is recommended, though this varies significantly based on local climate conditions, tree coverage, and roof pitch.
Customers in humid southeastern states report shorter effectiveness periods (sometimes as little as 2 years), while those in drier climates often see results lasting 5+ years. Several long-term users recommend scheduling periodic professional inspections to catch any new growth early and extend the effective life of the treatment.
Many reviewers mention that subsequent applications tend to be less expensive than the initial treatment since less intensive cleaning is required if maintenance is performed before significant regrowth occurs. This ongoing maintenance approach receives high satisfaction ratings for maximizing long-term value.
