Cobalt Ultra HT Ice and Water Shield (Single Roll)

### Cobalt Ultra HT Ice and Water Shield Single Roll The Cobalt Ultra HT Ice and Water Shield has garnered a largely positive reception among users, particularly for its exceptional adhesive quality and waterproof capabilities. Many customers were first-time users of peel and stick products, and their experiences were overwhelmingly favorable. The incredibly sticky nature of the material ensures that once it is applied, it stays put, making it an ideal solution for ensuring a tight seal on roofs, especially in vulnerable areas like edges and valleys. Users have reported successful application and performance even after extensive delays in their roofing projects, noting that the product has remained effective in preventing leaks for extended periods. In one case, a user applied the shield and, despite a two-year wait for shingle installation, experienced no leaks or degradation in the material's performance. Customer feedback does indicate a learning curve associated with installation; however, those who watched instructional videos found the process manageable and rewarding. The product's performance has led many users to wish they had utilized it more extensively on their roofs. Some feedback highlighted a noticeable change in the product's formulation between previous and recent versions—specifically, a transition from a black-lettered to a blue-lettered version. The new version has been described as slightly less sticky, offering users a chance to make adjustments, but reports also highlight some challenges with safety on steep roofs due to a slippery release agent. There are calls from users to revert to the earlier formula which provided a firmer footing during installation. Overall, Cobalt Ultra HT Ice and Water Shield is regarded as a reliable, effective, and necessary component for anyone looking to ensure a waterproof roof, although potential buyers should be aware of the recent formulation changes that could impact installation. ### Pros and Cons **
