CertainTeed Roofing Systems in Louisville, KY
A Roof Is More Than Shingles — It’s a Certified CertainTeed System
When homeowners think about roofing, they often think only about shingles. In reality, a high-performing roof is a complete roofing system, with each component working together to protect your home.
​
At River City Vinyl Supply & Roofing, we install CertainTeed Roofing Systems designed specifically for Kentucky and Southern Indiana weather. As a CertainTeed-certified contractor, we follow manufacturer-approved installation standards—because cutting corners can void warranties and shorten the life of your roof.
What Is a CertainTeed Roofing System?
A CertainTeed Roofing System is a layered assembly of compatible components engineered to work together—not mixed brands or shortcuts.
When installed correctly, a CertainTeed system helps:
-
Keep water out
-
Manage airflow and attic moisture
-
Improve energy efficiency
-
Qualify for enhanced manufacturer warranties
Each layer plays a role. When one component fails, the entire system is compromised.
​The 6 Key Components of a CertainTeed Integrity Roof System®â€‹
1. Waterproofing Underlayment
This is your roof’s first line of defense against leaks. CertainTeed’s self-adhering waterproofing underlayment is installed in the most vulnerable areas of the roof, such as valleys and penetrations, to help prevent water intrusion caused by wind-driven rain and ice dams.
2. Water-Resistant Underlayment
Installed over the roof deck, this layer acts as a secondary moisture barrier beneath the shingles. It adds an extra level of protection by helping block water infiltration if moisture ever makes it past the shingles.
3. Shingle Starter
Starter shingles are installed along roof edges and eaves. They’re designed to work in tandem with the shingles above, helping ensure proper sealing, wind resistance, and long-term performance. Skipping this step is one of the most common causes of early roof failure.
4. Shingles
Shingles are the most visible part of your roof — and CertainTeed offers a wide range of Good, Better, and Best options to match your home’s style and budget. When installed as part of a complete system, these shingles deliver durability, curb appeal, and industry-leading warranty protection.
5. Ventilation
A roof that breathes performs better and lasts longer. CertainTeed ventilation products allow air to move properly through the attic, helping keep your home cooler in summer, drier in winter, and reducing moisture-related damage that can shorten roof life.
6. Hip & Ridge Components
These finishing components protect the roof’s most exposed areas — the hips and ridges — while also adding a clean, polished appearance. Properly installed hip and ridge products help seal the system and complete the roof both functionally and visually.
