Why Roofing Underlayment Matters

Roofing underlayment might not be the most glamorous aspect of your home, but it plays a crucial role in protecting it from the elements. Here are a few reasons why it matters:

Weather Protection


Florida is no stranger to heavy rainfall, especially during hurricane season. A good roofing underlayment acts as a barrier against water infiltration, preventing leaks and water damage.

Heat Resistance

Florida’s scorching sun can take a toll on your roof’s shingles. Underlayment helps in reflecting heat away from your home, reducing energy costs and keeping your interior cool.

Wind Resistance

Hurricanes and strong winds are a reality in Florida. Proper underlayment installation helps keep your roof intact during high winds, preventing costly damage.

5 Florida Roofing Underlayment Requirements 📜


Florida has specific roofing underlayment requirements in place to ensure that homes are adequately protected against the state’s unique weather conditions. Here’s a breakdown of what you need to know:

1. Underlayment Material

The Florida Building Code requires roofing underlayment to be made of either:

  • Asphalt-saturated felt
  • Synthetic materials approved by the Florida Building Commission

Using approved materials is essential to comply with state regulations and ensure your roof can withstand Florida’s climate.

2. Minimum Underlayment Weight

Florida’s roofing code specifies a minimum underlayment weight of 15 pounds per 100 square feet for asphalt-saturated felt. This requirement ensures that the underlayment provides adequate protection against wind-driven rain.

3. Self-Adhering Underlayment

In areas with high wind speeds, self-adhering roof underlayment is often recommended or even required. This type of underlayment sticks to the roof deck, creating a secure seal that prevents water infiltration, even during severe storms.

4. Ice Barrier Requirements

In some parts of Florida, particularly in the northern regions, ice barrier underlayment may be necessary. This added layer helps prevent ice dam formation and water intrusion, which can lead to roof leaks and damage.

5. High Wind Zones

Florida is no stranger to high winds, especially during hurricane season. In high-wind zones, you may be required to use enhanced underlayment or install it with specific fastening methods to ensure it remains secure during storms.

How to Choose the Right Underlayment for Your Florida Home 

Now that you know the basics of Florida’s roofing underlayment requirements, let’s discuss how to choose the right underlayment for your home in 6 steps.

1. Consult a Professional

Before making any decisions, it’s a good idea to consult with a roofing professional. They can assess your specific situation, taking into account factors like your location, roof type, and local building codes.

2. Consider Climate

Florida’s climate can vary greatly from north to south. Coastal areas may experience salt spray, while inland regions can be prone to extreme heat. Make sure your chosen underlayment is suitable for your specific climate conditions.

3. Think About Longevity

Investing in high-quality underlayment might cost more upfront, but it can save you money in the long run. Quality materials will last longer and provide better protection for your home.

4. Look for Local Approvals

Check if the underlayment you’re considering is approved by local building authorities. It’s essential to ensure your choice complies with Florida’s regulations.

5. Consider Self-Adhering Underlayment

In high-wind areas or hurricane-prone regions, self-adhering underlayment can provide an extra layer of protection. It adheres directly to the roof deck, reducing the risk of water infiltration.

6. Roof Slope Matters

The slope of your roof can influence the type of underlayment you need. Low-slope roofs may require different underlayment than steep-slope roofs.

💰Investing in Quality Roofing Underlayment 💰

When it comes to protecting your home in Florida, investing in quality roofing underlayment is a smart move. It’s an essential part of your roof’s defense against the elements and can save you money on repairs in the long run.

Benefits of Quality Underlayment

Below, we go over a few key benefits of investing in quality underlayment for your Florida roof.

  • ✅Enhanced Durability: Quality underlayment can withstand the harsh Florida climate, ensuring your roof stays strong for years to come.
  • ✅Better Energy Efficiency: Reflective underlayment can reduce your cooling costs by reflecting heat away from your home, keeping it cooler during hot Florida summers.
  • ✅Peace of Mind: Knowing your home is protected by top-notch underlayment provides peace of mind, especially during hurricane season.

DIY vs. Professional Installation 

While some homeowners may be inclined to tackle roofing projects themselves, installing roofing underlayment is a job best left to the professionals. Here’s why:

  • 🛠️Safety: Roof work can be dangerous, especially for those without experience. Professionals have the training and equipment to work safely at heights.
  • 🛠️Quality Installation: Proper underlayment installation is critical for its effectiveness. Professionals have the expertise to ensure it’s done right.
