Ice and water barrier is a type of self sealing underlayment that adheres to the roof decking and waterproofs it.
Roof ice build up solutions.
There the water freezes gradually growing into a mound of ice.
The major issue with ice dams on the roof is that they trap the melting water running down from the top of the roof and thereby cause it the melted water to rise up underneath the roofing shingles and eventually seep through the boards and walls inside our homes.
Keep in mind that warm air leaking up through an attic floor can also contribute to ice build up.
If snow and ice build up high enough in the gutter it can provide a foundation for an ice dam.
What damage do ice dams cause.
When the weather gets warmer head up onto the roof and check for gaps in the roofing and waterproofing.
Gutters at the eaves can also trap snow and ice.
Why ice dams are dangerous.
The socks will create melt a channel in the ice to allow the water to run off your roof instead of building up along the eaves and leaking inside.
The flatter the pitch of the roof the easier it is for an ice dam to get a grip.
Removing snow from your roof will eliminate the essential component needed to create ice dams.
Low pressure steaming will gently remove the ice build up through the use of directed high temperature steam.
Next go up on the roof and put ice melt socks vertically one end onto the gutter and the other end up the roof slopes spacing them every 3 feet.
Track water stains higher up along the roof if you re uncertain of where a stain originates.
