When it comes to roofing, choosing the appropriate underlayment is just as crucial as selecting the right shingles. Two types often come to mind when it comes to this roofing component — synthetic and felt. In this blog, Quality Assurance Roofing delves into the pros and cons of each to determine which might be the best choice for your home.
Understanding Roof Underlayment Basics
Before we compare synthetic and felt underlayments, let’s clarify what roof underlayment is. It’s essentially a protective layer installed directly on your home’s roof deck. This layer plays a vital role in guarding against weather damage and water intrusion, which can lead to costly repairs if your roof covering is compromised.
Synthetic Underlayment: The Modern Standard
Synthetic underlayment is a high-tech alternative to traditional felt. It’s made from woven or spun polyethylene or polypropylene, which grants it exceptional durability and tear resistance. Thanks to its polymer-based composition, it’s also lightweight, making it easier and less costly to install due to reduced labor.
May roofing professionals go for synthetic underlayment because of the following attributes:
- Durability. It lasts longer and is less susceptible to tears and water damage.
- Weight. Lighter material, which may translate to quicker and less expensive installation.
- Lifespan: Synthetic underlayment usually lasts between 25-30 years, which can be cost-effective in the long run despite the initial higher cost.
Felt Underlayment: The Traditional Choice
Felt underlayment, also known as asphalt-saturated felt, has been the go-to choice for decades. It’s made by saturating paper or fiberglass mats with asphalt. Available in two thickness grades—#15 and #30—this material offers a reasonable degree of water resistance and durability.
Despite the prevalence of synthetic underlayment, roofers still use felt because of the following reasons:
- Cost. Generally less expensive upfront, making it a budget-friendly option.
- Absorbency. It has an innate ability to absorb moisture, which can be beneficial in certain situations.
Key Comparisons Between Synthetic and Felt Underlayment
When determining which underlayment is right for your home, several factors come into play, including durability, weight, and cost.
- Durability: Synthetic underlayment tends to offer more robust protection against extreme weather.
- Weight. Felt underlayment is heavier, potentially complicating the installation process and influencing labor costs for your roofer.
- Cost. Though felt is initially more affordable, synthetic underlayment may prove more cost-effective over time due to lower maintenance and replacement frequency.
- Installation. Synthetic underlayment can be faster to install due to larger rolls that cover more area, a factor worth considering when planning a roof replacement.
Making the Right Choice for Your Home
Choosing between synthetic and felt underlayment depends on individual circumstances. Synthetic underlayment is the more durable and longer-lasting choice, offering better protection under the hot sun and during bouts of severe weather. However, felt underlayment might be the preferred option for those on a tight budget or for specific architectural requirements.
