VIDEO: Water Drips

Water drips.

Water not only drips; it downpours.

Water freezes.

When water forms icicles on a roof, that's usually an indication of an ice dam, where liquid water collects behind an ice wall. Warmer water from higher up on the roof feeds this ice dam as it melts down to the lower, colder section. From here, the liquid water can find cracks and openings in the exterior roof.

Water drips in, unless the roof is equipped with original Ice & Water Shield®, invented by GCP Applied Technologies in 1978. Forming a direct adhesion to the roof deck and itself, Grace Ice & Water Shield® protects the roof from damage caused by Mother Nature.

When #RE0101Is an ice dam, rest assured the roof is safe with Grace Ice & Water Shield®.
