**Pros and Cons of buying a Rain Buster UU-B-790A Sealant with Mechanically Flashing**

The Rain Buster UU-B-790A is a popular gutter protection system designed to prevent clogs, reduce maintenance, and improve water flow in residential and commercial roofs. Below is a detailed breakdown of its advantages and disadvantages.

### **Pros**

1. **Effective Clog Prevention** The system uses a mesh screen that allows water to pass while blocking leaves, debris, and fine particles. This significantly reduces the risk of gutter clogs compared to traditional gutter guards.

2. **Mechanical Flashing** The included flashing ensures a secure seal between the gutter system and the roof, preventing leaks around the gutter s connection point. This is particularly useful for homes with steep or complex roofing.

3. **Durable Construction** Made from high-quality aluminum, the UU-B-790A is resistant to rust, corrosion, and weathering, providing long-term reliability in various climates.

4. **Easy Installation** The design is modular, allowing for straightforward installation without requiring professional help. This can save labor costs for DIYers.

5. **Improved Water Flow** By keeping gutters clear, the system ensures proper drainage, reducing water damage to fascia, siding, and foundation.

6. **Low Maintenance** Unlike traditional gutter guards, the mesh screen is less prone to clogging, meaning fewer cleanings and less upkeep over time.

7. **Compatibility with Most Gutters** The system is designed to fit standard K-style gutters, making it a versatile option for many homes.

8. **UV-Resistant Material** The aluminum used is treated to withstand prolonged sun exposure, maintaining performance over years.

9. **Reduced Pest Entry** The fine mesh prevents insects, rodents, and other pests from entering the gutters, which can be a common issue with open gutter systems.

10. **Warranty Coverage** Rain Buster offers warranties on their products, providing peace of mind against manufacturing defects.

### **Cons**

1. **Higher Upfront Cost** Compared to basic gutter guards or no protection at all, the UU-B-790A is more expensive to purchase and install. The mechanically flashing feature adds to the cost.

2. **Potential for Clogging in Heavy Debris Areas** While effective, the mesh can still clog in regions with excessive leaves, pine needles, or fine particles (e.g., near construction sites or in forested areas). Regular maintenance may still be required.

3. **Limited Lifespan** Although durable, aluminum gutter guards can degrade over time due to weather exposure, especially in harsh climates. Replacement may be necessary after 10 15 years.

4. **Installation Challenges** While modular, improper installation can lead to gaps or misalignment, reducing effectiveness. DIYers may struggle with precise fitting, especially on complex roofs.

5. **Restricted Water Flow in Extreme Cases** If the mesh becomes clogged, water may back up, potentially overwhelming the system. This is rare but possible if maintenance is neglected.

6. **Not Ideal for All Roof Types** Steep or highly sloped roofs may require additional flashing or adjustments to ensure a proper seal, which could complicate installation.

7. **Aesthetic Considerations** Some homeowners prefer a more seamless look, as the mesh and flashing may be visible from certain angles. While functional, it is not as discreet as some alternative gutter protection systems.

8. **Professional Installation May Be Recommended** For optimal performance, especially with the flashing component, some users opt for professional installation, adding to costs.

9. **Limited Customization** The system is designed for standard gutters and may not accommodate custom or non-standard gutter profiles without modifications.

10. **Potential for Ice Dams in Cold Climates** While the system prevents clogs, ice dams can still form if snow melts unevenly. The gutter guard itself does not prevent ice buildup, which may require additional solutions.

### **Conclusion**

The Rain Buster UU-B-790A is a robust and effective gutter protection system that excels in preventing clogs, improving drainage, and reducing maintenance. Its mechanically flashing feature enhances durability and leak prevention, making it a strong choice for homeowners seeking long-term gutter protection. However, the higher cost, potential clogging in debris-heavy areas, and the need for proper installation are drawbacks to consider.

For most residential homes in moderate to low-debris environments, this system offers excellent value. In regions with heavy foliage or extreme weather, additional maintenance or complementary solutions (e.g., leaf blowers for roof cleaning) may be necessary.

### **Recommendation**

If you prioritize **durability, ease of installation, and long-term clog prevention**, the Rain Buster UU-B-790A is a solid investment. It is particularly well-suited for:

- Homes in areas with moderate debris (e.g., suburban neighborhoods).

- Owners who want to minimize gutter cleaning frequency.

- Those who prefer a balance between cost and performance.

- Your budget is tight (cheaper mesh guards may suffice).

- You live in a high-debris area (supplement with a leaf blower or choose a finer mesh system).

- You prefer a more discreet look (some micro-mesh or reverse-curve systems are less visible).

For most users, the benefits outweigh the cons, making the UU-B-790A a **highly recommended choice** for gutter protection. However, weigh your specific needs against the system s features to ensure it aligns with your priorities.
