In most parts of the United States, you will find roofers mentioning one row of ice and water barrier in their bids for roofing projects. However, you must check out the municipality Building Code before finalizing the height of Ice and water barrier.

There should be a perfect balance between cold air intake vents and hot air exhaust vents. The cold air from the intake ones will push the warm air out of the attic space through exhaust vents. However, if the ventilation is not proper this process will not be able to carry out perfectly. Hence, the warmer will remain inside the attic space, which will warm the roof and melt the snow, but the cold here outside is going to freeze snow and create ice, this resulting in the continuation of freeze cycles.
