**Pros and Cons of buying a Lanco 313090585570 Seal Rubberized Elastomeric Roof Sealer (5-Gallon, Weatherproof)**

### **Pros**

1. **High Durability and Longevity** This elastomeric roof coating is designed to provide long-term protection against UV rays, weathering, and temperature fluctuations. It forms a flexible, rubber-like membrane that resists cracking, peeling, and deterioration, extending the lifespan of the roof.

2. **Excellent Waterproofing** The rubberized formula creates a seamless, waterproof barrier that prevents leaks, reducing the risk of water damage to the underlying structure. This is particularly useful for flat or low-slope roofs.

3. **UV Resistance** The product contains additives that protect against ultraviolet degradation, preventing the coating from becoming brittle or discolored over time. This helps maintain its appearance and performance for years.

4. **Easy Application** It can be applied with a brush, roller, or sprayer, making it suitable for both professional installers and DIY enthusiasts. The self-leveling properties ensure an even finish without excessive prep work.

5. **Weatherproof and Flexible** The elastomeric nature allows the coating to expand and contract with temperature changes, reducing the risk of cracking. It also performs well in various weather conditions, including rain and extreme heat.

6. **Energy Efficiency** The reflective properties of the coating can help reduce heat absorption, lowering cooling costs in warmer climates. This makes it a cost-effective choice for long-term energy savings.

7. **Versatile Compatibility** This product is designed to work on a variety of roofing substrates, including EPDM, TPO, PVC, modified bitumen, and metal roofs, making it a versatile option for different roof types.

8. **Low Maintenance** Once applied, the coating requires minimal upkeep. Periodic inspections and touch-ups may be necessary, but it generally stays in good condition with less frequent reapplication compared to traditional roofing materials.

9. **Cost-Effective for Roof Restoration** For older roofs that are still structurally sound but showing signs of wear, this sealer can be a more affordable alternative to a full replacement, providing a fresh, protective layer.

10. **Environmentally Friendly** Many elastomeric coatings, including this one, are low in volatile organic compounds (VOCs), making them a greener choice compared to some traditional roofing materials.

### **Cons**

1. **Initial Cost** While it can save money in the long run, the upfront cost of purchasing and applying a high-quality elastomeric sealer can be higher than basic roof coatings or sealants. The 5-gallon size may not be sufficient for large roofs, requiring multiple purchases.

2. **Application Skill Required** Although it s relatively easy to apply, achieving a flawless, even coat requires some skill to avoid streaks, bubbles, or uneven thickness. Poor application can lead to premature failure or reduced effectiveness.

3. **Surface Preparation is Critical** For the best results, the roof surface must be clean, dry, and free of debris, oil, or loose material. Neglecting proper prep work can compromise adhesion and performance, leading to peeling or blistering.

4. **Drying Time** The product may require several days to fully cure, depending on weather conditions (temperature, humidity, and sunlight). This downtime can be inconvenient for homeowners or businesses needing immediate roof protection.

5. **Limited Color Options** Most elastomeric sealers come in standard colors like white or gray, which may not match the aesthetic preferences of some homeowners. While white is energy-efficient, darker colors could absorb more heat.

6. **Potential for Contraction Gaps** In very cold climates, extreme temperature drops can cause the coating to contract slightly, potentially creating tiny gaps if not applied thickly enough. This is usually minor but worth considering for extreme environments.

7. **Not a Permanent Fix for Structural Issues** If the underlying roof has significant damage (e.g., sagging, rot, or major leaks), the sealer will only provide temporary protection. A full roof replacement may still be necessary in severe cases.

8. **Application Tools May Be Required** While brushes and rollers work, some users may prefer a sprayer for larger areas, which can add to the cost of tools or rental fees.

9. **Limited Manufacturer Warranty** Warranty terms can vary by brand and retailer. Some products may offer limited warranties (e.g., 5 10 years), while others provide longer coverage. Always check the warranty details before purchasing.

10. **Professional Application May Be Recommended** For optimal results, especially on large or complex roofs, hiring a professional applicator can ensure proper coverage and longevity. DIY applications may not always meet industry standards.

### **Conclusion**

The **Lanco 313090585570 Seal Rubberized Elastomeric Roof Sealer** is an excellent choice for homeowners or businesses looking to extend the life of their roof, enhance waterproofing, and improve energy efficiency. Its durability, flexibility, and ease of application make it a strong contender for both flat and low-slope roofs. However, the success of the product depends heavily on proper surface preparation, careful application, and consideration of long-term needs.

For those willing to invest time in preparation and application or hire professionals this sealer offers significant benefits in terms of protection and cost savings over time. It is particularly well-suited for roofs that are already in decent condition but show signs of aging or weathering.
