Understanding The Purpose of The Roof Underlayment

By Stacy Mellete

When replacing your roof, the underlayment is one of the first things we install. It is an important part of a residential roofing system because the underlayment covers the roof deck.
The underlayment’s main purpose is to protect your roof deck from all sorts of damage, so it’s important to invest in a high-quality underlayment when replacing your roof in Riverview FL. Learn more about the underlayment here:

Understanding The Purpose of The Roof Underlayment

The Purpose of the Underlayment

The underlayment provides a layer of separation between the roof sheathing and the shingles, and creates a moisture barrier. Roof coverings like asphalt shingles act as your roof’s primary defense against roof leaks. The underlayment acts as the secondary barrier.
In addition, while newer homes use plywood or oriented strand board for roof sheathing, old homes used fir and pine boards. The resin pockets in these old boards can react chemically with some roof covering materials, so the underlayment prevents this.


The underlayment also acts as temporary protection during roof installation in Riverview FL. While most roof installations are completed quickly, there is usually a little time when the underlayment is the only thing protecting the roof.

The underlayment performs this job adequately because all manufacturers design their underlayment to prevent the passage of moisture in its liquid form. As residential and commercial roofing expert in Riverview Florida, we use only the best quality underlayment for our customers.
