Is Synthetic Roof Underlayment Better Than Felt in Denver

In the ever-evolving world of roofing, there’s a debate that has taken center stage in Denver: Is synthetic roof underlayment better than traditional felt underlayment? As a third-generation family of contractors at Ernie’s Roofing, with over four decades of experience in the Mile-High City, we’ve witnessed the roofing industry’s transformation firsthand. In this comprehensive 3000-word blog post, we’ll delve deep into the nuances of roofing underlayment materials and provide you with expert insights on why synthetic roof underlayment might just be the superior choice for your Denver roofing projects.


The Mile-High Challengesynthetic-roof-underlayment

Denver’s unique climate presents a challenge that not every city faces. We’re blessed with 300 days of sunshine, but we also contend with sudden temperature shifts, intense UV rays, hailstorms, and heavy snowfall. These weather extremes can put immense stress on your roofing system, making the choice of underlayment material even more critical.

At Ernie’s Roofing, we understand the importance of selecting the right materials for Denver roofs. Over the years, we’ve closely observed the performance of both synthetic roof underlayment and traditional felt underlayment. Let’s break down the reasons why synthetic often takes the lead in the Mile-High City.



Synthetic Roof Underlayment: The Top Choice

1. Unrivaled Waterproofing

Denver’s unpredictable weather patterns mean that your roof needs robust protection against moisture. Traditional felt underlayment, while still an option, can sometimes struggle to maintain its integrity in wet conditions. Synthetic underlayment, on the other hand, is designed to be inherently waterproof. It forms a tight, impenetrable barrier against rain, snow, and ice, ensuring your roof remains watertight year-round.

2. Durability for Decades

When it comes to longevity, synthetic roof underlayment has the upper hand. Our experience has shown that it can endure the extreme temperature fluctuations that Denver experiences. It doesn’t degrade or become brittle under the relentless Colorado sun, and it won’t tear or crack during those harsh winter months. In essence, it’s built to last, saving you both time and money in the long run.

3. Lightweight and Contractor-Friendly

Synthetic underlayment is a lightweight champion. This quality makes the installation process smoother, especially when compared to the heavier rolls of traditional felt. The reduced weight puts less strain on your roof’s structure and can speed up the installation process. It’s a win-win for contractors and homeowners alike.

4. Resistant to Mold and Rot

Denver’s climate can be somewhat unforgiving, but synthetic underlayment doesn’t flinch. It’s impervious to mold and rot, which can be common issues in humid areas. This resistance ensures that your roof remains not only strong but also healthy, safeguarding your indoor air quality.

5. Enhanced Safety

Safety is paramount in the roofing industry, and synthetic underlayment contributes to a safer work environment. Many synthetic materials come with textured surfaces that provide superior traction for roofing professionals, reducing the risk of accidents during installation and maintenance.



Cost-Effective Considerations

We understand that the initial cost of materials is a significant factor in any roofing project. Traditional felt underlayment is often perceived as the more budget-friendly choice. However, when you factor in the long-term durability and reduced maintenance costs associated with synthetic underlayment, it becomes clear that the investment pays off over time. Think of it as a smart choice that not only protects your home but also your wallet.


Going Green in Denver

Denverites are known for their environmentally conscious choices. If you’re one of them, you’ll be pleased to know that synthetic underlayment offers eco-friendly options. Many synthetic materials are recyclable, reducing their impact on landfills. Moreover, their extended lifespan means fewer resources are used over time, aligning with Denver’s sustainability goals.
