Ice and water shield is an essential component of any roofing system, especially in areas where heavy snowfall and freezing temperatures are common. In the PNW it is a vital component to ensure the heavy rains and wind does not cause a leaking roof. This waterproof membrane is applied to the most vulnerable areas of a roof, such as the eaves and valleys, to prevent water from penetrating the structure and causing damage. Other areas ice and water shield is installed include around chimneys, skylights or any other penetrations in the roof.
One of the main benefits of ice and water shield is that it can prevent ice dams from forming on the roof. Ice dams occur when snow melts on the upper portion of a roof and then refreezes at the eaves, creating a barrier that prevents water from flowing off the roof. This can lead to water infiltration, leaks, and structural damage. Ice and water shield creates a barrier that prevents water from penetrating the roof, even if an ice dam forms.
Another advantage of ice and water shield is that it provides an extra layer of protection against leaks. The membrane is self-adhesive, which means that it can be applied directly to the decking without the need for additional fasteners. This provides a tight seal that prevents water from penetrating the roof decking and causing damage. As a self-adhered membrane, it also has the benefit of melting at higher temperatures when initially installed which seals any gaps or holes created by fasteners penetrating the membrane.
Installing ice and water shield is a relatively simple process, but it is important to make sure that the membrane is applied correctly. Ice and water shield is a vital component of any roofing system, especially in areas where heavy snowfall and freezing temperatures are common. It provides an extra layer of protection against leaks and prevents ice dams from forming on the roof. By installing ice and water shield, you can ensure that your roof will be protected against the elements, keeping your home safe and dry.
