Ice and Water Shield
GAF offers several Ice and Water Shields that serve as increased protection from the elements in vulnerable roofing areas. While it may seem unnecessary to add this extra leak protection, there are several benefits to these products, which can be especially valuable in harsh weather climates.
Ice and Water Shields provide extra protection from wind-driven rain, which can leak through the roof deck and cause serious structural roof damage. These shields can also prevent melting ice and snow from seeping into the interior of any structure. Called ice dams, this melting ice and snow can cause serious problems if a roof is not properly protected. Further, unlike many other types of underlayment, these GAF products ensure a total waterproof seal. This can prevent a myriad of problems associated with leaking, such as the staining of interior walls and ceilings.
