A roof system is made up of three main parts. The shingles are the most prominent part of a roof, but the underlayment, ice and water barriers, ventilation, and insulation all help your roof do its job. Ice and water underlayment products help keep water out of your roof because they stick to the roof deck and form a waterproof barrier.

What Are Ice and Water Barriers?
Having roofing contractors add in an ice and water underlayment beneath the shingles is one approach that is both practical and effective. These barriers are impermeable, so they seal firmly around nails and keep moisture out. They adhere directly to the roof decking and have a direct attachment.
Roofing services in Manchester, TN say that they protect the eaves, valleys, roof penetrations, and the entire roof.
Help Prevent Ice Dams
Ice and water barriers offer watertight barriers that aren’t simply for torrential downpours and violent winds. The word “ice” in the phrase “ice and water barrier” has a specific meaning. The ideal conditions for an ice dam include rooftop snow, heat loss from the attic, and below-freezing temps. The consequence is worse the more snow there is and the colder it is.
You can prevent the formation of the ice dam by resolving any of the aforementioned problems. You can take action to reduce the amount of snowmelt on your roof, but you can’t stop snow from falling or water from flowing downhill.
