Stop the dam.
Before it starts.
Fill the Dam Ice mesh bag with ice melt suitable for your roof and gutters to help create a drainage channel through roof-edge ice dams.
An ice dam turns your roof into a bathtub.
Snow melts from attic heat, runs down the roof, then refreezes at the cold overhang above your gutters. That ridge of ice keeps growing until meltwater has nowhere to go but backward — under the shingles, into the deck, and down through your ceiling.
By the time you see a stain on the drywall, the water's already been in the attic for days.
Cut a channel. Let gravity finish the job.
Fill the mesh bag with your chosen ice melt and position it across the ice dam to help create a path for trapped water to reach the gutter.
Locate the dam
Find the ridge of ice sitting at your roof edge, usually right above the gutter line.
Fill the mesh bag
Fill a Dam Ice mesh bag with your chosen ice melt, then pull the drawstring tight to close it.
Lay it across the dam
Position the filled bag perpendicular to the dam so it spans from above the ice to the open gutter.
Let it drain
The ice melt inside the bag creates a channel through the ice dam, giving trapped water a way out.
Sized for the roof you're standing under.

Before you order.
Does the bag include ice melt?
No. Dam Ice is the drawstring mesh bag. Fill it with your own ice melt suitable for your roof and gutters.
How do I close the bag?
After filling the mesh bag, pull the drawstring tight to close the opening.
What ice melt should I use?
Choose an ice melt suitable for your roof and gutters. Follow its manufacturer's directions for application, temperature limits, and use around pets and plants.
Where do I place the filled bag?
Position the filled mesh bag across the ice dam so it spans from above the ice to the open gutter. Follow the application guide and the directions for the ice melt you choose.
Don't wait for the ceiling stain.
Get Dam Ice in the garage before the next freeze-thaw cycle turns into a repair bill.
