Mostly it has to do with the accumulation of weight from debris plus water or possibly snow ice.
Why do my gutters filled with ice.
There s a couple variables that will cause your gutters to come loose.
Tie a long string to the filled pantyhose so you can easily retrieve them later.
First the sheer weight of ice dams in gutters can cause them to detach from the home warp or otherwise become damaged.
If the downspout is clear then water will fall right through and won t freeze.
In addition to this water is very heavy and will pull your gutters away form the home.
When your gutters get clogged the water can t properly drain.
One way that harsh winter weather can damage gutters is ice buildup.
These situations all impact the flow of water through the gutters and cause a snowball effect of home damages.
The warm temperatures from your attic will cause the snow and ice to melt on your roof.
The reason for the weight of ice is that debris in the downspout is getting wet then freezing and adding unnecessary weight.
Another equally troubling problem are ice dams.
Snow thaws to water then refreezes.
Another way ice dams impact the flow of water is in the amount of space they take up in the gutter system.
This constant refreezing can cause ice dams and icicles to form along the gutters.
Then lay the filled pantyhose horizontally on the ice in your gutter.
However as the temperatures drop the melted snow and ice will begin to freeze again.
Salt will eventually melt and can damage any grass or plants below your gutters.
The stacked up ice and snow causes the run off to flow over the lip of your gutters and create long icicles.
This pool of water can leak into your home and cause damage to walls ceilings insulation and other areas.
An ice dam is a wall of ice that forms at the edge of the roof usually at the gutters or soffit.
Therefore if it never melts except uniformly when the temperature is above freezing the problem is avoided.
Once the freezing rains turns into snow it will quickly accumulate inside your gutters and fill the gutter cavity.
When it forms the water then backs up behind the ice dam and creates a pool of water.
Once rain water freezes water will no longer flow through your gutters and layers of ice form.
The thickness of the ice is in direct correlation to the amount of freezing rain that falls.
By mentioning ice damming you understand that it is caused by snow melting in a warm area and refreezing in a cold area.
Thawing won t be possible because the gutters will hold in the cold the same way wrapping soda in an aluminum can does.
Ice buildup in your gutters prevents the flow of melted snow to your down spouts for proper drainage.
