🎬 Opening Scene: The Shingle Showdown
Imagine this: a roofer who understands the importance of ventilation and insulation in your roofing system. You’re binge-watching your favorite home improvement show, and the host is raving about the latest shingle, tile, or metal roof styles. He’s discussing the colors, textures, hail resistance, and even eco-friendly options.
Shingles are the stars of the roofing world, flaunting their curb appeal and stealing the spotlight. But here’s the plot twist: beneath those glamorous shingles lies the unsung hero of your roof—the underlayment. The shingles, tile, or metal roofing material that you see from your curb is the cherry on top of what keeps your house dry and not a soggy mess.
And most, if not all, homeowners are unaware of it.
At Denny’s Roofing, LLC, we believe it’s time to give underlayment its moment in the sun (and rain and snow). We’re here to debunk the myth that shingles alone are the key to a leak-free roof.
Spoiler alert: without a solid underlayment, your shingles are like a superhero without their suit—vulnerable and exposed.

🕵️♂️ Myth Busted: Shingles Alone Can’t Save the Day
Let’s set the record straight. Shingles are essential—they protect your home from extreme weather elements and add aesthetic appeal —but they must be complemented with proper ventilation. But relying solely on asphalt shingles to keep your home dry is like expecting a raincoat to keep you warm in a blizzard; proper underlayment is key. Without the proper layers underneath, you’re in for a soggy surprise.
The underlayment is the critical layer between your shingles, as well as tile and metal roofing, and your roof deck. It acts as a secondary and significant weather barrier against water infiltration, especially during Colorado’s unpredictable weather conditions. Think of it as the unsung sidekick that ensures your roof’s longevity and performance.
Underlayment: The Foundation of a Leak-Free Roof
1. Water Resistance is significantly enhanced with the right combination of underlayment and insulation.
Underlayment provides what we consider the MAIN layer of protection against water intrusion. If shingles are damaged or blown off during a storm, the underlayment helps prevent water from seeping into your home. Interesting fact: If you have your roof what we refer to as being properly “dried-in,” meaning it has an adequate layer of underlayment but no shingles, tiles, or metal, it can withstand rain and water intrusion for about 6 to 9 months on its own.
The shingles, tiles, and/or metal roof covering, along with proper insulation, protect the roof from extreme weather elements such as snow, hail, high winds, monsoon rains, and similar conditions. The shingles also protect it from the harsh UV rays of the summer heat. It keeps the underlayment from deteriorating prematurely.
2. Weather Protection is crucial for any new roof installation.
Colorado’s climate can be harsh, with heavy snowfall, hailstorms, and intense UV exposure, making proper insulation and ventilation essential. A high-quality underlayment shields your roof deck from these elements, reducing the risk of leaks and structural damage.
3. Fire Resistance
Some underlayment materials offer fire-resistant properties, providing an added layer of safety for your home. This is particularly important in areas prone to wildfires.
4. Improved Longevity
By protecting the roof deck from moisture and other damaging elements, underlayment extends the life of your entire roofing system. It’s an investment in the long-term health of your home.
