Our Proven System

 Water does not move downward only. When surfaces remain in continuous contact, moisture can migrate upward and laterally through tight seams, laps, and compressed joints by capillary action.

This behavior is amplified on low-slope roofs, at concealed transitions, and in areas where water dwells rather than drains quickly. Once capillary pathways are established, moisture can travel significant distances inside an assembly before becoming visible.

Systems that rely on continuous contact between layers provide no mechanism to interrupt this movement. Water that enters often remains trapped, leading to ongoing saturation rather than a single, identifiable leak.

  Through-fastened roof and wall systems place screws and gaskets directly in the primary water plane. These fasteners are subjected to constant thermal expansion and contraction, wind-induced movement, and vibration.

Over time, fastener holes elongate, gaskets harden or compress unevenly, and tear lines can form in the panel material. Even minor movement at a single fastener can allow water to enter the assembly.

Because thousands of fasteners may exist across a roof or wall surface, failures are difficult to isolate and often recur shortly after repairs.

  In exposed-fastener assemblies, environmental forces act locally. Wind gusts, uplift, and thermal movement transfer load directly to the nearest or weakest fastener.

When one fastener loosens or fails, loads shift to adjacent fasteners, accelerating progressive failure. Once water gains access at these locations, leakage often spreads beneath panels or insulation rather than remaining localized.

This behavior explains why leaks frequently appear after wind events and why repairs targeting individual fasteners rarely provide lasting results.

 Many commercial buildings are constructed using lapped metal panels supplied in fixed lengths, commonly 12–20 feet. When roof or wall planes exceed these lengths, multiple horizontal joints are introduced along each panel run.

Each horizontal joint relies on laps, sealants, and fasteners to resist water intrusion. As these components age, even minor degradation at any one joint can allow water to enter the assembly.

The cumulative effect of multiple joints significantly increases long-term leakage risk, especially on large roof surfaces.

  Horizontal joints and penetrations are often located over insulation layers. When water enters at these points, it is absorbed by insulation rather than immediately appearing inside the building.

Moisture can migrate laterally and downward within the insulation, causing leaks to emerge far from the original entry point—sometimes days after rainfall.

This concealed migration leads to repeated misdiagnosis, unnecessary repairs, prolonged moisture conditions, and mold development.

 Conventional roof and wall assemblies frequently trap moisture behind panels, within insulation, or inside wall cavities.

Without a dedicated drainage or ventilation path, incidental moisture remains concealed, prolonging drying cycles and accelerating material degradation.

These conditions often persist unnoticed until structural damage, corrosion, or interior finishes are affected.

 Low-slope roofs experience prolonged water dwell, increased hydrostatic pressure, and higher reliance on sealants and lap integrity. These conditions amplify failure at seams, laps, penetrations, and terminations—especially in systems that depend on exposed fasteners, tape, or shallow seam engagement.

Conventional low-slope metal and membrane assemblies often include numerous panel joints, end laps, and transitions across long roof planes. Over time, sealants age, fasteners loosen, tapes fail, and minor movement creates leak paths that allow water to migrate laterally beneath the roof surface and into insulation or wall assemblies. Because water may travel far from the point of entry, leaks are often difficult to diagnose and repeatedly mis-repaired.

The mechanically locked over-batten system addresses these conditions by:

• Eliminating exposed fasteners and sealants from the primary water plane
   
• Using full-length panels to reduce or eliminate transverse joints
   
• Providing a continuous drained and ventilated air space beneath the new roof layer
   
• Maintaining positive seam compression across long roof runs and low slopes
   
• Allowing incidental moisture to drain and dry rather than remain trapped
   

By separating layers and removing reliance on chemical sealing, the system performs predictably under extended wet conditions common to low-slope commercial and industrial roofs.

This approach is particularly suited to large-format buildings where conventional low-slope repairs have proven temporary, disruptive, or ineffective.

Removing an existing roof or wall assembly introduces immediate risk in active facilities. Tear-off exposes interiors to weather, debris, dust, and fall hazards while increasing the likelihood of equipment damage and operational downtime.

For buildings that must remain in continuous use, tear-off-driven repairs frequently create more risk than they resolve.
