What is Roofing Underlayment:
Roofing underlayment plays an important role in how well your roof system performs in numerous exposure elements: rain, wind, snow, ice, fire-to name the most important forces your roof may face. A complete roof system is more than just the final roofing material. A roof system is comprised of multiple components, and roof underlayment is an important element of an effeictive roof system designed to protect both life and property.
Roofing underlayment functions:
1.It repels water. Roof underlayment helps to ensure that water drains off the roof.
2.It provides backup protection in the event of ice or water damage. Roof underlayment can seal around fastener shanks for a leak-resistant fit.
3.It provides extra weather protection. Some roof materials are more susceptible to wind uplift damage. In these incidences, the roof underlayment becomes a backup layer of weather protection to guard against rain until the roof can be repaired or replaced.
4.It protects your roof deck while you work on it. Roof underlayment prevents the roof deck from being exposed to the elements, before, or while, the roofing material is being installed. Ideally, the roof-covering material would be installed as soon as possible, but in reality, the roof may be protected by only the underlayment for days, weeks, or sometimes months. It also needs to resist the wear and tear that occurs when the roof-covering material is being installed.
