Stay Dry with Spengler Industries: The Science Behind Our Watertight Diamond Shingles

Water can be one of the most destructive forces for a roof if not properly managed. At Spengler Industries, we understand how to make sure water goes exactly where it should—and nowhere else. Our diamond shingles offer a time-tested solution that ensures your roof stays watertight, beautiful, and enduring.

Copper Diamond Roof Shingles are excellent at keeping roofs weather tight.

Understanding Water’s Behavior: Why Most Roofs Fail

Water has a mind of its own. It doesn’t just flow down—it can seep, creep, and climb. This phenomenon, driven by capillary action and pressure differentials, often causes poorly designed roofs to fail.

Consider this: Have you ever noticed how water drips unpredictably from a poorly designed water pitcher? Roofs without proper water channels behave the same way. They allow water to back up along the shingle edge, and once physics takes over, water starts to move in unexpected—and unwelcome—directions.

Most traditional shingle roofs rely on overlap rather than interlocking designs, leaving them vulnerable. Precipitation cools the roof surface, while residual heat from underneath creates a pressure differential. This pressure pulls water upward, bypassing the overlap and causing leaks.

What Makes Spengler’s Diamond Shingles Different?

Spengler Industries’ diamond shingles are engineered with a unique interlocking design that goes beyond mere overlap. These shingles feature established water channels, acting as a traffic director for precipitation. Here’s how they work:

  • Pointed Edge Orientation: Our shingles are installed with the pointed edge facing downward, ensuring water flows seamlessly down and away from the structure.
  • Interlocking Design: Unlike loosely applied “interlocking” claims in the industry, our shingles truly lock water out, leaving no path for infiltration.
  • Versatility with Purpose: While diamond shingles offer horizontal and angular layouts, only specific applications are suitable for roofs. Others are reserved for wall cladding to maintain optimal performance.

Proven Design Meets Timeless Aesthetics

You might wonder: How do our shingles compare to traditional materials like slate, which have been used for centuries? The answer lies in their design.

In Germany, for example, slate roofs with ambiguous water channels are always installed at an angle to direct water away effectively. You’ll never see angled slates set horizontally—an unmistakable nod to the importance of water channeling. Spengler’s shingles follow the same principle, using proven methods to create a watertight system, even in horizontal layouts.

What Sets Spengler Industries Apart

  1. Precision Engineering: Our shingles are meticulously designed to ensure no water intrusion, making them a lifelong investment.
  2. Performance in All Climates: Whether in snow, rain, or extreme temperature changes, our shingles remain watertight and secure.
  3. Sustainability: Manufactured with durable materials, Spengler Industries’ shingles minimize waste by lasting for decades.

Why Interlocking Matters

Unlike most roofs that rely on adhesive or exposed fasteners to stay watertight, Spengler shingles use a true mechanical interlock with a hidden fastening system. This precision-fit system actively prevents water from penetrating, ensuring long-term protection against leaks and damage.
