Choosing the Right Roofing Underlayment: Felt or Synthetic?
When it comes to roofing, choosing the right materials is key to protecting your home. One of the most important parts of a roof is the underlayment. But with so many options, you might wonder: should you choose felt or synthetic underlayment? In this post, we’ll explain what each option offers and help you decide which one might be best for your roof.
What is Roofing Underlayment?
Underlayment is a layer of material placed between your roof deck (the plywood or OSB board) and the shingles. It adds an extra layer of protection against weather, especially moisture. In roofing, the underlayment is like your roof’s hidden shield, protecting your home from leaks, water damage, and other potential issues.
Why is Roofing Underlayment Important?
Underlayment is essential for several reasons:
- Water Resistance: It acts as a barrier against rain, snow, and other sources of moisture.
- Protection Against Wind: During strong winds, underlayment helps prevent water from seeping into your roof if shingles get lifted.
- Extra Insulation: It adds a bit of extra insulation to your roof, helping keep your home more energy-efficient.
Underlayment is required by building codes in many areas, making it a vital part of any roofing project.
Types of Roofing Underlayment: Felt and Synthetic
There are two main types of underlayment: felt and synthetic. Let’s explore both types and what they offer.
1. Felt Roofing Underlayment
Felt underlayment, also known as tar paper or felt paper, is the traditional choice. It’s made from a mix of paper and organic materials soaked in asphalt for water resistance.
Pros of Felt Underlayment:
- Affordable: Felt is usually cheaper than synthetic underlayment.
- Good for Low-Slope Roofs: It’s a popular choice for roofs with low slopes.
- Readily Available: Since felt has been around for a long time, it’s easy to find.
Cons of Felt Underlayment:
- Less Durable: Felt is more likely to tear, especially in strong winds or during installation.
- Heavy: Thicker felt underlayment can be quite heavy, which may add weight to your roof.
- Not as Weather-Resistant: Felt underlayment can soak up water if exposed for too long, which can lead to problems.
When to Use Felt: Felt underlayment is a good option if you’re on a budget and live in an area with mild weather. However, it may not be the best choice for roofs that need to withstand extreme temperatures, heavy rain, or strong winds.
2. Synthetic Roofing Underlayment
Synthetic underlayment is made from lightweight polymers, such as polypropylene or polyethylene. It’s a newer option but has quickly become popular due to its strength and durability.
Pros of Synthetic Underlayment:
- Lightweight: Synthetic underlayment is lighter than felt, so it puts less strain on your roof.
- Durable and Tear-Resistant: It’s much stronger than felt and is less likely to rip or tear, even during installation or in harsh weather.
- More Weather-Resistant: Synthetic underlayment is waterproof and can handle longer periods of exposure to the elements.
- Better Slip Resistance: Many synthetic underlayments are designed with slip-resistant surfaces, making it safer for roofing crews.
Cons of Synthetic Underlayment:
- Higher Cost: Synthetic underlayment is generally more expensive than felt.
- Limited Availability in Some Areas: In some locations, synthetic underlayment may be harder to find.
When to Use Synthetic: Synthetic underlayment is an excellent choice if you live in an area with extreme weather, heavy rain, or snow. It’s also a great option if you want a long-lasting, durable product.
Felt vs. Synthetic: Which is Right for You?
When deciding between felt and synthetic underlayment, consider these key factors:
- Weather: If you live in an area with mild weather, felt underlayment might be enough. But if your area sees heavy rain, strong winds, or extreme temperatures, synthetic underlayment offers better protection.
- Budget: Felt is usually more affordable, making it a good choice for those on a tighter budget. However, synthetic underlayment might be worth the investment if you want more durability and protection.
- Roofing Project Size: For large roofing projects, synthetic underlayment can save time and effort because it’s lighter and easier to handle.
- Longevity: If you plan on keeping your roof for many years, synthetic underlayment could be the better option, as it tends to last longer than felt.
Final Thoughts on Roofing Underlayment
Both felt and synthetic underlayment can provide good protection for your home. Felt may be suitable for smaller, lower-budget projects in areas with mild weather. On the other hand, synthetic underlayment offers a longer-lasting, more durable solution that’s ideal for challenging weather conditions.
Choosing the right underlayment depends on your budget, location, and the specific needs of your roof. Whichever you choose, quality installation is key to ensuring your roof protects your home effectively.
