Standing Seam Metal Roof Detail
Homeowners pick standing seam metal for a roof they never want to replace: it sheds rain and snow fast and hides its fasteners under the seams. In ArcSite's standing seam metal roof detail, you see how panels meet at a valley, layer by layer.
Key Features
This standing seam metal roof detail includes:
- Valley pan centered over the framing
- Panels hemmed on each side of the valley
- Offset cleats fastened into the plywood substrate
- Butyl tape and approved sealant under the panel ends
- Underlayment stripped in over the valley
- Thermal expansion allowance at each panel end
- Minimum gap callout between the two panel ends
Both panel ends stop short of the valley center with room to expand, so seasonal movement never tugs the cleats loose.
