Overlap Metal Roofing Panels Lengthwise
Step by Step Guide to Metal Roofing Panel Overlap Let’s break it down:
- Step 1: The Placement of First Panel
- Position that first panel along the chalk line, which should have been set up in the planning stage.
- Make sure the roof edge has a small overhang (usually 1-2 inches) so water can run off.
Step 2: Picking up the First Panel
Insert a screw gun or drill to secure the panel in the structure of the roof.
- Space screws along ribs of the panel, typically 12–18 inches apart for secure fastening.
- Step 3: Move the Second Panel
- This means repeat, sliding the second panel up to cover over at least 1 inch of the top panel along length.
- Confirm the alignment is straight and even so there are no gaps.
Get ready for the second panel
Use the same fastening technique as the first panel to secure the second panel in place.
Screw down firmly enough to form a watertight seal, but don’t overtighten or you will strip the panel.
Repeating the Process
Place and fasten more panels, repeating the same overlap and alignment across the roof.
- After fastening each panel, check for proper line up, so that there are no gaps in between.
- Installing Installation Tips
- Best Practices for dealing with overlapping panels
- Follow the manufacturer’s instructions for overlap and fastening, always.
Keep screw locations evenly spaced to increased stability and prevent any movement of the panels.
