Single Ply

Loadmaster Roof Deck for Single Ply Roofing Systems

Single ply roofing membranes depend on a stress-free environment to perform at their best over the long term. Loadmaster's roof deck system is specifically designed, engineered, and tested to deliver exactly that — providing a fully bonded, high-performance base that protects single ply membranes for decades.

Engineered for Full Adhesion and Long-Term Performance

Loadmaster's roof deck assemblies are built to ensure adhered single ply membranes bond completely to the surface. This full bond is critical — it protects the membrane from damaging winds, thermal movement, and other stresses that can cause premature failure and costly repairs.

Terminator System: Controlling and Eliminating Membrane Stress

When paired with Loadmaster's Terminator System, the results go even further. Together, the two systems work to:

  • Control or eliminate virtually all membrane stress at terminations and transitions

  • Extend the lifespan of the single ply roof covering

  • Delay recover or replacement costs — saving building owners tens of thousands of dollars or more

A Smart Long-Term Investment for Building Owners

Roof replacement and recovery are among the largest capital expenses a building owner can face. By reducing membrane stress and extending roof life, Loadmaster's system delivers measurable long-term savings — making it one of the smartest investments in commercial roofing available today.

The Right Foundation for Single Ply Roofing — That's Loadmaster

For contractors and building owners who need a reliable, proven base for single ply roofing systems, Loadmaster delivers the performance, protection, and cost savings that no other roof deck system can match.

Modified Bitumen

Loadmaster Roof Deck for Modified Bitumen (Mod Bit) Roofing

Modified Bitumen roofing performs best when it has a stable, stress-resistant foundation beneath it. When bonded to a Loadmaster Roof Assembly, Mod Bit roofing receives exactly the protection it needs to thrive in demanding environments — and the performance record proves it.

A Track Record Decades in the Making

Loadmaster's history with Modified Bitumen roofing goes back to the late 1980s. During those first installations — when only coatings were used for surfacing — the combination of Mod Bit and Loadmaster roof deck technology achieved:

  • 30 years of watertight performance as a proven baseline

  • 34 years reached by the oldest recorded installation — a record at the time

These results established Loadmaster as a trusted, long-term foundation for Modified Bitumen roofing systems.

New Technology, Even Greater Performance

Today, the addition of white ceramic granule surfacing takes performance even further. When combined with the Loadmaster Terminator System, the Modified Bitumen roof's predicted performance life is expected to:

  • Surpass the existing 34-year record

  • Potentially reach 40 years of reliable, watertight performance

A Cost-Saving Roofing Solution

Longer roof life means fewer recovers, fewer replacements, and significant long-term savings for building owners. The Modified Bitumen and Loadmaster combination is one of the most cost-effective roofing solutions available — delivering decades of performance while reducing total lifecycle costs.

Modified Bitumen Roofing Done Right — With Loadmaster

For contractors and building owners seeking maximum durability and long-term value from a Mod Bit roofing system, Loadmaster provides the proven foundation to make it happen.

Built Up Roofing

Loadmaster Roof Deck for Built-Up Roofing (BUR) Systems

Built-Up Roofing (BUR) is a time-tested roofing system — but because it is constructed entirely on the job site, it can be vulnerable to environmental stresses and installation errors when placed over a conventional roof deck. Loadmaster changes that equation entirely.

A Foundation That Dramatically Extends BUR Performance

When properly installed over a Loadmaster Roof Deck, a Built-Up Roof's performance life improves dramatically. Loadmaster's stable, inorganic base minimizes the stresses that typically shorten the lifespan of job-site-constructed roofing systems — giving BUR the foundation it needs to reach its full potential.

The Record-Holder: 36 Years and Counting

The proof is in the numbers. A gravel-topped, 3-ply BUR system installed over a Loadmaster Roof Deck — originally spec'd for just 15 years — currently holds the longevity performance record:

  • 36 years of watertight performance before sustaining severe hail damage

  • Projected 40-year lifespan had the hail storm not occurred

  • More than double its original design life of 15 years

This remarkable performance is a direct result of the stability and protection that Loadmaster's roof deck system provides.

Real Savings: $800,000 in Avoided Costs

The longevity of this Loadmaster-supported BUR system saved the building owner approximately $800,000 in roof recover and replacement costs over its lifetime. That's the kind of long-term value that no conventional roof deck can match.

Built-Up Roofing and Loadmaster — The Smart, Long-Term Choice

For building owners and roofing contractors who want to maximize the lifespan and cost efficiency of a Built-Up Roof system, Loadmaster provides the proven foundation to make it possible.
