Ice and water shield is a self-adhesive roofing underlayment that provides an extra layer of protection against water infiltration caused by ice dams or heavy rain. It is particularly useful on steel roofs, which can be prone to water seepage around seams, fasteners, and edges. This product is typically applied along roof edges, valleys, and around penetrations like chimneys or vents, creating a waterproof barrier that prevents melted snow or rain from getting underneath the metal panels. It’s important because even a small leak under steel roofing can lead to rust or structural damage over time. Ice and water shield is designed to stay flexible and adhere well to smooth surfaces like metal, making it a solid choice to reduce water intrusion risk, especially in colder climates where ice dams are common.
For homeowners considering a DIY inspection, you can safely check for signs of water damage in your attic or ceilings such as dark stains, mold, or dampness after winter storms, which might indicate that ice and water shield was either not used or has failed. If you’re unsure whether the shield was installed or if the roof has weakened, or if you spot missing or peeling sections, it’s smart to reach out to a professional roofer with steel roofing experience. When talking to a contractor, useful questions include: “Can you confirm if ice and water shield was used beneath the steel panels during installation or replacement?” and “How do you ensure proper adhesion and overlap of the shield on steel roofing to maintain the warranty?” These questions help make sure your roof is properly protected and that any work adheres to manufacturer guidelines for longevity.
