What is Ice and Water Shield on Your Roof?

May 04 2023

As a homeowner, it’s essential to understand the components that protect your Memphis roof from the elements, especially in colder climates where ice and snow can cause significant damage. One such component is the ice and water shield, a protective underlayment designed to prevent leaks and water damage. In this blog, we will delve into the world of ice and water shields, explaining what they are, how they work, and why they are a crucial element in safeguarding your roof.

What is an Ice and Water Shield?

An ice and water shield is a self-adhering, rubberized asphalt membrane applied to your decking and under your shingles on your roof. This specialized underlayment creates a watertight barrier, protecting your roof deck and home’s interior from leaks caused by ice dams, wind-driven rain, and other water-related issues.

How Does an Ice and Water Shield Work?

The ice and water shield works by sealing around nails, fasteners, and other penetration points, preventing water from seeping through and causing damage. Its self-adhesive nature allows it to bond directly to the roof deck, ensuring a continuous, watertight seal. In cold climates, it is particularly effective at preventing damage caused by ice dams, which occur when snow melts and refreezes at the edge of the roof, forcing water to back up under the shingles.

Where Should Ice and Water Shield be Installed?

While local building codes may vary, it is generally recommended to install an ice and water shield along the eaves, valleys, and rakes of the roof, as well as around any roof penetrations such as vents, chimneys, and skylights. These areas are more susceptible to water infiltration and leaks, making the added protection of an ice and water shield especially important.

Ice and Water Shield vs. Traditional Felt Underlayment

While traditional felt underlayment has been used for many years as a protective barrier beneath roofing materials, it does not offer the same level of protection as an ice and water shield. Unlike felt, which can tear and is prone to water absorption, the ice and water shield’s rubberized asphalt composition creates a much more durable and effective watertight seal. While it is often more expensive than felt, the ice and water shield’s superior performance and longevity make it a worthwhile investment for many homeowners.

The Importance of Proper Installation

To fully benefit from the protection offered by an ice and water shield, proper installation is crucial. This means working with a qualified roofing contractor who has experience installing ice and water shields and adhering to local building codes and manufacturer guidelines. Improper installation can lead to compromised performance and a reduced lifespan for your roofing system.
