Purpose Of Using Ice And Water Shield Under Metal Roofing

Ice and water shield is crucial under metal roofing. It prevents leaks caused by ice dams. Ice dams form when snow melts and refreezes, leading to water seeping under the roof. The shield acts as a barrier, stopping water from infiltrating the roof. It’s especially vital in regions with cold winters.

The shield protects against wind-driven rain. This type of rain can find its way into small crevices and cause damage over time. The shield blocks its entry, ensuring the roof remains watertight. Overall, using ice and water shield under metal roofing enhances durability and guards against weather-related issues, prolonging the roof’s lifespan.

Benefits Of Using Ice And Water Shield Under Metal Roofing

Increases roof lifespanBy providing extra protection against water damage, the ice and water shield can help extend the lifespan of the metal roofing system.

Using ice and water shield under metal roofing offers several benefits.

Waterproofing: Ice and water shield acts as an additional layer of waterproofing protection, especially in areas prone to heavy rainfall or snow accumulation. It helps prevent water infiltration, which can lead to damage to the roof deck, insulation, and interior of the building.

Prevents Ice Dams: In colder climates, ice dams can form on roofs, especially at the eaves, which can cause water backup and leakage into the attic or interior spaces. Ice and water shield helps to prevent ice dams by creating a barrier that stops water from seeping through vulnerable areas.

Seals Penetrations: Ice and water shield adheres tightly to the roof deck and around penetrations such as vents, chimneys, and skylights, creating a watertight seal. This reduces the risk of leaks at these critical points.

Flexible and Self-Sealing: Ice and water shield is typically made of a rubberized asphalt material that remains flexible even in cold temperatures. This flexibility allows it to conform to the contours of the roof and self-seal around nails or other fasteners, providing added protection against leaks.

Longevity: When installed correctly, ice and water shield can extend the lifespan of the roof by preventing water damage and deterioration of the underlying materials. This can result in fewer repairs and maintenance costs over time.

Added Insulation: Some ice and water shield products offer thermal insulation properties, which can help improve the energy efficiency of the building by reducing heat loss through the roof.

Insurance Benefits: In some regions, installing ice and water shield may qualify for insurance discounts or incentives because it enhances the roof’s resistance to damage from severe weather events.

Overall, using ice and water shield under metal roofing provides an extra layer of protection against water infiltration, ice dams, and other weather-related issues, ultimately contributing to the durability and longevity of the roof system.

Installation Process Of Ice And Water Shield Under Metal Roofing

Installation Process Of Ice And Water Shield Under Metal Roofing

Installing ice and water shield under metal roofing is crucial for protection against leaks and ice dams. Begin by cleaning the roof thoroughly, removing any debris or dirt. Next, unroll the ice and water shield along the eaves of the roof, ensuring it overlaps the edge by a few inches.
