Coastal areas are particularly vulnerable to the effects of ice and water. The changing climate and rising sea levels have increased the frequency and severity of storms and flooding in these regions. As a result, it is crucial for coastal communities to implement effective measures to protect their structures from damage caused by ice and water. One such measure is the use of an ice and water barrier. This article will explore the importance of ice and water barriers in coastal areas and their role in preventing costly and potentially dangerous issues.

Role of Ice and Water Barriers

An ice and water barrier is a protective membrane that is installed under roofing materials in coastal buildings. It provides an additional layer of defense against water infiltration caused by ice damming, heavy rainfall, and strong winds. Ice damming occurs when warm air in the attic melts the bottom layer of snow on the roof, causing it to flow down and refreeze at the roof’s overhangs. This ice buildup can lead to water seeping under the roof shingles, causing leaks and potential structural damage.

Ice and water barriers are typically made of self-adhering asphalt-modified bitumen, creating a waterproof seal that prevents water from penetrating the roof. They are installed along the eaves, valleys, and other vulnerable areas where leaks are likely to occur. The installation of an ice and water barrier is an essential step in ensuring the long-term durability of coastal structures.

Benefits of Ice and Water Barriers

The primary benefit of installing an ice and water barrier is the prevention of water damage. By creating a watertight seal, these barriers protect the underlying structure from leaks, rotting, and mold growth. This is particularly important in coastal areas where the constant exposure to moisture can accelerate decay and compromise the integrity of the building.

Furthermore, ice and water barriers provide an additional layer of protection against ice damming. They prevent the formation of ice dams by stopping the melted snow from infiltrating the roof system. This mitigates the risk of costly repairs or replacement of damaged roofing materials.

In addition, ice and water barriers enhance the energy efficiency of a building. By preventing water infiltration, these barriers maintain the insulation’s effectiveness and reduce heat loss during cold weather. This helps to minimize energy consumption and lower heating costs, making ice and water barriers a cost-effective investment in the long term.

Installation Process

The installation process of ice and water barriers begins with the removal of existing roofing materials. The roof deck is thoroughly inspected for any signs of damage or decay. Once the deck is deemed suitable, the ice and water barrier is rolled out and cut to fit the specific dimensions of the roof. The membrane is then adhered to the deck, creating a continuous waterproof layer.

It is important to note that ice and water barriers should be installed by experienced professionals to ensure proper application. Incorrect installation can result in insufficient coverage or inadequate sealing, rendering the barrier ineffective. Therefore, it is advisable to hire certified roofing contractors with expertise in coastal construction.


In conclusion, ice and water barriers play a crucial role in protecting coastal structures from the damaging effects of ice and water. They create a watertight seal that prevents leaks, rotting, and mold growth, ultimately preserving the integrity and longevity of buildings in these vulnerable areas. Installation by qualified professionals is essential to ensure the efficiency and effectiveness of these barriers. As climate change continues to pose challenges to coastal communities, the implementation of ice and water barriers will become increasingly important for the resilience of coastal infrastructure.
