Avoiding Overlaps: The Importance of Custom Length Roofing Panels

Introduction In traditional roofing, sheets were often delivered in standard sizes, requiring multiple horizontal overlaps to cover a large industrial span. At Rishonn & Reyansh, we advocate for a different approach. Every overlap is a potential point of failure; therefore, the move toward custom-length, onsite roll-formed panels is not just a trend—it is a technical necessity for high-performance buildings.

The Risks of Multiple Overlaps

  1. Capillary Action: When two sheets overlap, water can be "sucked" upward between the sheets through capillary action, leading to hidden leaks and internal rusting.

  2. Fastener Fatigue: Overlaps require double the amount of stitching screws. Over time, thermal expansion causes these screws to loosen, creating gaps.

  3. Material Waste: Standard sizes lead to significant "end-lap" waste, where you pay for several inches of material that simply sits hidden under another sheet.

The Solution: Onsite Roll-Forming By utilizing onsite roll-forming technology, R&R can produce single-length panels that stretch from the ridge to the eave. Whether your shed is 10 meters or 60 meters long, a single continuous sheet eliminates the need for end-laps entirely.

  • R&R VERDICT: Always insist on "Eave-to-Ridge" single-length sheets whenever the site logistics allow it. Eliminating horizontal overlaps is the most effective way to ensure a 100% leak-proof roof. If your project exceeds 12 meters in length, onsite roll-forming is the only professional way to ensure structural integrity and a clean, seamless finish.
