Grace Ice & Water Shield:
Long Island's
Best Roof Protection
The last line of defense against roof leaks
As a Grace Ice and Water Shield contractor, I install Grace Vycor on all my roof installation projects. Whether it’s new construction or a roof replacement on an older home, I insist on laying down Grace Ice and Water Shield as an underlayment from the beginning. I’ve been a Long Island roofer for over 38 years, and I know just how important it is to start every roof with a solid foundation.
In 2022 CertainTeed purchased GCP Applied Technologies, Grace’s parent company. Since that time Grace Ice and Water Shield has been the recommended underlayment for the CertainTeed Integrity Roof System, the best roof on the market. The roof underlayment protects your roof deck from water. Wind-blown rain and water buildup from ice dams can breach asphalt shingles. A waterlogged wooden deck may require extensive roof repair or even a complete roof replacement.
I’m a certified CertainTeed contractor, so I get special prices on Grace Vycor roofing products and pass the savings on to customers. Roofing contractors without CertainTeed certification pay full price. Most don’t even both to offer Grace as an option. And since most people outside the roofing industry have never even heard of Grace, they have no idea what Grace Ice and Water Shield is or how its superior performance protects their family through Long Island’s worst weather.
You can’t see the roof underlayment after installation. Because of this, many roofing contractors cut corners at this stage. They use cheap, inferior roof coverings and they do a shoddy job in laying it down. And after a few seasons, the unsuspecting homeowner starts wondering why their roof keeps springing leaks. It doesn’t matter if they did everything else right in their roof installation. Without a secure underlayment, any new roof will fail before its time.
When rain, impacts, or age wear down your shingles, the underlayment is your last line of defense. A good underlayment can be the difference between new shingles and a new roof. The pennies you save on the wrong underlayment often bring you an ongoing source of expenses and headaches. We know every step of the roofing installation matters, and that’s why we use only Grace . Another roofing company may offer lower bids for your roofing project, but you get what you pay for.
Protects better, lasts longer than the alternatives
There are two types of roof underlayment alternatives that are less expensive than Grace Ice & Water Shield. But a lower price is about the only advantage they offer. These underlayments may be suitable for homes in more temperate climates with consistent fair weather. But Long Island roofs face blistering summer sun and tropical storms, followed by winter ice storms and hurricanes.
Grace Select is designed for maximum temperature resistance. It shields your roof deck and damage from both cold and heat. This helps you save money on costly New York utility bills. During rainstorms Grace protects your home against water intrusion and water leaks that can damage your roof and your walls. Its high quality seal ensures that water pours off your roof, not into your home.
ASPHALT SATURATED FELT
Many roof installers use asphalt saturated felt as their roof underlayment material. The asphalt makes the felt water-resistant, but not watertight. Asphalt saturated felt tears easily, so careless roofers can damage the underlayment when fastening or walking across it. And asphalt saturated felt has a shorter expected lifespan than other common underlayments.
SYNTHETIC ROOFING UNDERLAYMENT
Synthetic roofing underlayment instals more quickly than asphalt felt and is far more durable. But synthetic underlayment costs considerably more than asphalt felt. Installers must also use cap fasteners rather than staplers. And while synthetic roofing underlayment offers more water resistance than asphalt felt, it does not create a watertight seal.
Your Best Choice: Rubberized Asphalt with Grace
If you want an absolutely waterproof roof underlayment, rubberized asphalt is your only choice. Rubberized asphalt underlayment can last up to 50 years. It’s also easy to install and easy to repair a torn rubberized asphalt membrane.
Grace Ice & Water Shield is by far the best-known name in rubberized asphalt underlayment. It provides your roof with the best protection against water damage. GRACE ICE & WATER SHIELD is the original self-adhesive underlayment. More than 2 million homes rely on Grace Ice & Water Shield to protect them against inclement weather.
Grace Ice & Water Shield consists of two waterproofing layers. A high-density cross-laminated polyethylene film backs an adhesive rubberized asphalt surface. A release paper backing protects the adhesive and makes the rolls easier to handle. Roofers remove the release paper for installation. The adhesive bonds tightly to the roof deck. And Grace’s Ripcord® allows for split release on demand, which helps ensure tight connections around skylights and windows.
NOT ALL ROOFERS ARE EQUAL.

- Ripcord. Installers can split the Grace Ice & Water Shield membrane for faster application. This also allows better position in valleys and around dormers.

Will Grace Ice & Water Shield prevent ice dams?
Every winter we repair many Nassau County roofs damaged by ice dams. A Grace Ice & Water Shield underlayment will stop damage from water that builds up on your roof due to ice dams. But, unfortunately, it won’t stop the ice dams from forming.
Ice dams occur when heavy snow buildup melts during the day, then refreezes during the night when the temperatures drop. As the melt-freeze cycles continue, ice builds up at the roof’s edge. When the snow melts, the ice dam traps the water.
In time, this water can work its way beneath the shingles. There it can find its way into your attic, causing water damage to ceilings and walls. If ignored too long, an ice dam can do significant damage.
The Grace underlayment is water-tight. When that water reaches the Grace Ice & Water Shield layer, it has nowhere else to go. This means that when roofers come to look at the damage, they just need to replace a few shingles. Without the Ice & Water Shield layer, they might have to replace a section of your roof deck.
Here are some ways you can limit the chances of an ice dam forming on your Bronx roof.
- Clean all leaves, sticks and other debris from your gutters and down spouts. This lets snow melt flow freely to the ground without building up.
- Use a roof rake to keep snow off your roof. Heavy snow loads can not only lead to ice dams, they can cause roof failure due to the weight.
- Clear icicles and snow from your gutters and down spouts.
Ventilation is crucial with Grace Ice & Water Shield
Underlayment defends your home against moisture. Ventilation supports air flow into and out of the attic space. We find that many roofing issues we handle stem from improper ventilation.
Attic clutter can block vents, as can home attic renovations. Roof installers often treat venting like an afterthought. But an improperly vented attic can give you problems at every season of the year.
Warm humid indoor can rise to the attic where it meets the cold roof deck. This causes frost and to form on the interior of your roof deck. Attic frost is common throughout the New York metropolitan area. But most homeowners rarely visit their attic and aren’t even aware that ice is building up.
Ventilation keeps air flowing through the roof, which keeps the roof deck temperature closer to the outdoor temperature. This helps reduce ice dam occurrences and attic frost, which helps reduce the risk of roof leaks and damage.
During a Queens summer, ventilation ensures a circulation between hot attic air and cooler outdoor air. This reduces your air conditioning bills. It also prevents your roof from becoming dangerously overheated in the sun. High temperatures shorten the life of your asphalt shingles and can void manufacturer warranties.
