The short answer
Standing seam runs continuous panels ridge to eave with concealed fasteners locked into raised seams, so nothing penetrates the water plane. It costs roughly $24,000 to $55,000 against a 40 to 50 year service life.
Specifications
| Factor | Detail |
|---|---|
| Typical cost | $24,000 to $55,000 |
| Service life | 40 to 50 years plus |
| Wind rating | 140+ mph typical |
| Impact rating | Class 4 |
| Maintenance | Essentially none |
| Solar | Clamp on, no penetrations |
Where it performs
- Two to three times the life of asphalt
- Class 4 impact rating and very high wind ratings
- Kynar finishes reflect solar heat and hold color
- No fastener penetrations to fail
- Suits rainwater collection
- Non combustible, which matters on rural lots
The trade-offs
- Highest upfront cost of the common residential options
- Can dent cosmetically in severe hail
- Requires an installer who understands thermal movement
- Some HOAs restrict it
What we install
We install 24 and 26 gauge standing seam with Kynar PVDF finishes. On barns and shops, exposed fastener panels are the economical and appropriate choice.
