Do I Need an Ice and Water Shield for a New Roof Installation on Long Island?
Yes, you need an ice and water shield when building a new home or having a roof replacement on Long Island. This waterproof membrane is installed underneath shingles in the areas most vulnerable to water intrusion. It’s not optional on Long Island. It’s required at roof eaves to prevent damage from ice dams and wind-driven rain.
Renew Roofing Solutions is available for roof installation and replacement throughout Long Island. We will install an ice and water shield to ensure your home is code-compliant and protected from the elements.
What is an Ice and Water Shield?
An ice and water shield is a different system from standard underlayment. It is a rubberized self-adhesive membrane that bonds with the roof deck, sealing all gaps and nail penetrations. It prevents water entry even when water is pushed sideways or pushed upward by ice.
Ice and Water Shield Installation is Often Required by Building Code
Most jurisdictions on Long Island require ice and water shields at the eaves, extending 24 inches past the wall line.
Your Long Island roofing contractor might also install this specialized membrane in roof valleys and around chimneys and skylights. Although not required by building code, extra protection in these areas can reduce the likelihood of developing leaks.
A licensed roofer will evaluate your roof and install an ice and water shield at the following locations:
- Eaves: This is the minimum required zone, where ice dams can force water to move up the roof and underneath the shingles.
- Valleys: When two surfaces meet to create a valley, there’s a high volume of water collection/drainage and a higher risk of water intrusion. The membrane keeps water from compromising the deck, even if there’s constant rainfall or slow-moving meltwater.
- Chimneys and Skylights: These penetrations are high-risk and prone to leaks, even with flawless flashing installation. Adding a membrane creates an extra layer of security to protect your home.
- Low-Slope Sections: Areas of the roof with a low pitch drain more slowly. Adding a membrane here prevents water from pooling and saturating the deck.
A licensed roofer from Renew Roofing Solutions will review the geometry and design of your roof and will recommend the minimum ice and water shield installation as a baseline. If additional shielding is required at high-risk areas, these will be recommended as optional upgrades to maximize weatherproofing and roof durability.
Why Doesn’t My Roof Already Have a Protective Membrane for Ice and Water?
Older roofs, especially those installed before 1995, might not have a modern ice and water shield because it wasn’t required by code. This can surprise many homeowners when seeing the ice and water shield on a quote. It’s not an upsell; it’s a requirement that will help protect your home.
- Without a shield, there’s a higher risk of ice dams or wind-driven rain forcing water into the roof deck.
- Water penetration causes rot, ceiling stains, and insulation damage.
- The damage can develop over months or years. By the time it’s detected, you could be looking at a significant roof repair bill.
Your Long Island home will be better protected with an ice and water shield. Although it adds expense to a new roof installation or roof replacement, it’s an investment that will ultimately pay for itself with a longer-lasting roof and a home that is protected from leaks.
