The Importance of Roofing Underlayment in McKinney: What You Need to Know


When it comes to roofing, you may have heard terms like “felt” or “underlayment” being tossed around, leaving you wondering what these roofers are talking about. In this blog post, we’ll demystify these terms and explain why they are essential components of a roofing system.

Traditional Roofing and 15lb Felt Paper:

Many older homes with their original roofs are likely to have what’s known as 15lb felt paper as part of their roofing system. If you were to take a closer look at it, you’d notice that it closely resembles construction paper – thin, prone to tearing, and not something you’d want as the primary protection for your roof.

The Problem with Multiple Layers:

In some cases, when roofing layers are replaced over the years, roofers might take shortcuts. Instead of properly assessing and repairing the roof’s decking, they simply add another layer of 15lb felt paper on top of the existing one. This means that not only do these homeowners have inadequate protection in the form of construction paper, but they also have two layers of it.

Performance Roofing’s Approach:

At Performance Roofing, we have a higher standard for roofing installations. Instead of relying on outdated and insufficient materials, we upgrade our homeowners to a synthetic underlayment, ensuring a more robust and long-lasting roofing system.

Synthetic Underlayment:

Our synthetic underlayment is a modern roofing material designed to be highly durable and waterproof. Unlike traditional felt paper, it doesn’t tear or rip easily. It comes in large rolls, covering the entirety of the roof, and acts as a crucial barrier between your roofing deck and shingles.

Ice and Water Barrier:

In addition to the synthetic underlayment, we go the extra mile by installing an ice and water barrier around all penetration points and in all valleys of your roof. This added layer of protection ensures that your home is watertight even before the shingles are installed.


In the world of roofing, the underlayment plays a critical role in safeguarding your home from the elements. While 15lb felt paper may have been the norm in the past, Performance Roofing takes your roofing to the next level with a synthetic underlayment and an ice and water barrier. When you choose Performance Roofing, you can rest assured that your roof is built to last and meets the highest standards of quality and protection. Don’t settle for construction paper when you can have a roof that’s truly prepared for anything.
