Why Palisade® Butyl-HT PLUS is the Top Choice for Self-Adhered Roof Underlayment

For decades, asphalt-based (bitumen) products were the standard. But as roofing technology has advanced, pure butyl adhesive has emerged as the clear gold standard, specifically for self-adhered applications. 

Discover why pure butyl is the superior solution for your home, and how our Palisade® brand delivers that performance through products like Palisade® Butyl-HT PLUS.

1. Superior Temperature Tolerance 

Old-school asphalt adhesives have a temperature problem. In the freezing cold, they become brittle and lose their stickiness. In the scorching summer heat, they can become an oily, oozing mess that can actually damage your roof deck or drip onto fascia boards.

Pure Butyl adhesive is different. It is chemically engineered to remain stable across a massive temperature range. 

• In the Cold: It stays flexible and tacky, allowing for installation even in late autumn or winter.
• In the Heat: It has an incredibly high melting point. This is crucial for metal roofs or dark shingles that trap heat. Products like Palisade® Butyl-HT PLUS are designed specifically to withstand high-temperature environments (up to 265°F) without degrading. 

2. Unmatched Sealability 

The primary job of a self-adhered underlayment is to waterproof the most vulnerable parts of your roof—eaves, valleys, and around vents. These are the areas where water (and ice dams) try to get in. 

Butyl rubber is "viscoelastic." In plain English, this means it flows around fasteners. When a roofing nail punctures a butyl-based underlayment, the adhesive creates an instant, airtight gasket around the nail shank. Asphalt can do this to an extent, but butyl does it better and maintains that seal for longer.

3. Chemical Compatibility

This is a technical point that matters. Standard asphalt/bitumen can react negatively with certain flexible plastics (like PVC) or other roofing materials, causing them to break down over time. Pure butyl is chemically inert. It plays nice with almost every building material, ensuring that your roof system works together rather than fighting against itself. 

Knowing the benefits of superior adhesives, we recommend underlayments that utilize this advanced technology.

• Palisade® Butyl-HT PLUS: For the critical seal areas, Palisade® Butyl-HT PLUS is a game-changer. It combines that pure butyl adhesive with their patented STRONGHOLD™ skid-resistant surface. It gives installers better traction (making the job safer and faster) while giving homeowners the peace of mind that their eaves and valleys are sealed with the best chemistry on the market.
• Palisade Products: Paired with the self-adhered power of Palisade® Butyl-HT PLUS,  Palisade synthetic underlayments offer lightweight, tear-resistant protection for the rest of the roof deck. Unlike traditional felt paper which absorbs water and wrinkles, NovaSeal® lays flat and stays strong, providing a secondary water barrier that outlasts and outperforms the old standards, while offering stronghold ski-resistant surface 

Your roof is a system. Putting high-end shingles or metal over cheap, asphalt-based paper is like putting a Ferrari engine in a rusted-out frame.

By choosing pure butyl technology found in Palisade® Butyl-HT PLUS and pairing it with the durability of palisade, you are investing in a roof that is sealed tighter, lasts longer, and withstands the elements better.
