When it comes to new roof installations, most homeowners tend to focus on shingles, tiles, or metal panels. However, the real hero of your roofing system lies beneath the surface: the roof underlayment. This essential layer acts as a waterproof barrier between your roofing material and the structure of your home. Without it, your property could face leaks, water damage, and reduced roof performance.

What Is Roof Underlayment?

Roof underlayment is a protective sheet installed directly over your roof deck before the final roofing material is added. It provides an extra layer of defense against rain, wind, and moisture—especially during Houston’s unpredictable weather.

Why Is It Important in New Installations?

1. Moisture Protection 🌧️ – Prevents water from seeping into your home if shingles are damaged or blown away.

2. Longevity 🏠 – Extends the life of your roof by reinforcing its resistance against weather.

3. Energy Efficiency ☀️ – Some underlayments reflect heat, keeping your building cooler in the Houston heat.

4. Building Code Compliance 📑 – In many areas, including Houston, underlayment is required by code for safety and durability.

Types of Roof Underlayment

• Felt Underlayment: Traditional, affordable option but less durable.

• Synthetic Underlayment: Modern choice with stronger protection, lighter weight, and higher resistance to tearing.

• Rubberized Asphalt: Premium option with superior waterproofing, ideal for homes prone to heavy rainstorms.

When investing in a new roof, don’t overlook the importance of underlayment. It’s the foundation of a strong, leak-free, and long-lasting roofing system. Choosing the right type can make all the difference in protecting your home from costly repairs.
