The self-adhering underlayment below shingles on residential sloped roofs that prevents the water leaks in roofs caused by the melting during the day of snow on roofs and the freezing of that melt during the night that climbs up from the bottom roof edge.

Ice and water shield is a self-adhesive waterproofing membrane used on roofs to protect against water infiltration caused by ice dams or wind-driven rain. It is typically installed along the eaves, valleys, and other vulnerable areas of the roof to provide an additional layer of protection against leaks.
Glaciers can reshape the drainage patterns of a shield by eroding the landscape and creating new channels for water flow. As glaciers advance and retreat, they can leave behind moraines and other landforms that affect how water drains across the shield. Melting glaciers can also increase water flow, leading to changes in drainage patterns.
Water and ice are not the same. Water is a liquid state of H2O molecules, while ice is the solid state of those same molecules. At temperatures below 0 degrees Celsius, water freezes and turns into ice.
When you drop a block of ice in boiling water, heat from the water will transfer to the ice, causing the ice to melt. The heat will continue to transfer from the water to the ice until the ice completely melts and reaches the same temperature as the water.
One form of frozen water in the South Pole is ice, which can be found in glaciers, ice shelves, and pack ice.
Glaciers can alter the drainage patterns of a shield by creating valleys and basins through erosion. As glaciers move, they carve out new paths for water to flow, influencing the direction and speed of drainage. Glacial meltwater can also interact with underlying soil and rocks, affecting groundwater movement and storage.
