What is Roof Underlayment, and Why Does It Matter?
When homeowners think about roofing, they often focus on shingles or tiles. However, the layer beneath these materials plays a critical role in protecting the home. Roof underlayment acts as a barrier against moisture, wind, and ice. It helps prevent leaks and extends the lifespan of the roofing system. Choosing the right underlayment ensures better protection and durability for your home.
At Phoenix Roofing and Solar, we prioritize high-quality materials to keep roofs strong and weather-resistant. Understanding underlayment and its benefits will help you make the best choice for your roofing project.
What is Roof Underlayment?
Underlayment is a protective layer installed between the roof deck and the outer roofing material. It provides extra defense against water infiltration, wind-driven rain, and ice buildup. Without underlayment, roofs would be more vulnerable to leaks and structural damage.
There are three main types of underlayment, each with different benefits:
Asphalt-Saturated Felt: This traditional option, also known as felt paper, offers basic water resistance. It comes in different thicknesses, with 30-pound felt providing better durability than 15-pound felt.
Synthetic Underlayment: Made from lightweight and tear-resistant polymers, this option offers improved water resistance and longer-lasting protection.
Rubberized Asphalt Underlayment: This premium material provides excellent waterproofing. It is ideal for areas with heavy rainfall or ice dams.
Choosing the right type depends on your local climate, budget, and roofing material.
Why is Underlayment Important?
Although not visible once the roof is complete, underlayment plays an essential role in protecting your home.
1. Prevents Water Damage
Shingles and metal panels help repel water, but they are not completely waterproof. If water seeps underneath, underlayment stops it from reaching the roof deck. This extra layer prevents leaks, rot, and long-term structural damage.
2. Protects Against Ice and Snow
In colder climates like Ohio, ice dams can form along roof edges. These ice formations trap melted snow and force water under the shingles. A high-quality underlayment prevents this water from reaching the roof deck, protecting against moisture-related issues.
3. Enhances Wind Resistance
Strong winds can loosen or lift shingles, exposing the roof to rain and snow. Underlayment provides an extra layer of protection, reducing the risk of leaks and damage. Even if shingles become loose, underlayment helps prevent immediate water intrusion.
4. Adds Fire Resistance
Some underlayment materials, like synthetic or rubberized asphalt, have fire-resistant properties. Choosing fire-rated underlayment adds another layer of safety to your home.
5. Extends Roof Lifespan
By preventing moisture buildup, reducing heat exposure, and strengthening wind resistance, underlayment helps extend the life of your roof. A strong and well-protected roof reduces the need for frequent repairs and replacements.
How to Choose the Right Underlayment
Selecting the best underlayment depends on several factors, including climate, roofing material, and specific protection needs.
Asphalt Shingles: Synthetic underlayment works best because it is lightweight, moisture-resistant, and long-lasting.
Metal Roofs: Rubberized asphalt underlayment provides superior waterproofing and helps reduce condensation buildup.
Wet or Snowy Areas: A waterproof self-adhering underlayment offers the best protection against leaks and ice dams.
At Phoenix Roofing and Solar, we help homeowners select the right underlayment for their specific needs to ensure long-term performance.
The Importance of Proper Installation
Even the best underlayment will not perform well if installed incorrectly. Poor installation can cause gaps, wrinkles, or misalignment, reducing its effectiveness. Professional roofing contractors follow best practices to ensure a secure and seamless installation.
