Copper valley flashing is an outstanding solution to waterproof roofing valleys. Not only will it add lasting protection and timeless beauty, it can also save homeowners from costly maintenance expenses in the long-run. Unfortunately, however, many homeowners hesitate due to cost concerns; therefore, this guide explores Copper valley flashing cost details pertaining to types of copper flashing options available, pricing by roof size category as well as long-term benefits so as to help make sound decisions and budget accordingly for long-term value versus initial expenses.
What is Copper Valley Flashing?
Copper valley flashing is an attractive metal insert installed between roof planes to channel rainwater away from seams to prevent leaks. Copper’s lasting qualities make it highly desirable:
- Longevity: Lasting 50-100+ years with proper Installation.
- Corrosion resistance: Develops protective patina
- Workability: Easy to form, solder, and shape
- Aesthetic appeal: Enhances curb appeal and resale value
Common types include open, closed-cut, W-valley, and custom-fabricated copper flashings.
Cost of Copper Valley Flashing by Types:
Standard V‑Valley (Open or Closed):
- 16 oz 10ft lengths with 18′-24′ width typically cost from $147-150.
- 20oz gauge adds $210-220
- Quantity discounts available (e.g., each unit for 50+ units’ cost only $149.95 each)
Example prices:
- 18x10foot copper strips 18in by 10 feet 10oz are approximately $147.595
- 24″ × 10′, 16 oz copper: add $37 → ~$185
- 36″ × 10′, 16 oz copper: add $111 → ~$259
W‑Valley (Raised Rib):
- 16 oz, 10 ft W‑valley: Usually $229–$230 each for 24″ width
- Wider sizes (18-24 in widths) usually cost anywhere from $360-475 depending on supplier.
Custom-Fabricated:
- Costs may range significantly 20-50% more than stock options.
- Workers calculate gauge thickness, profile complexity, and labor.
- Example: A bespoke 24″ 20 oz W‑valley could reach $500–$700+ per piece.
Cost of Copper Valley Flashing by Roof Size:
Copper valley flashing comes in linear feet. So, we estimate its costs with respect to roof valley length:
Small Roof (~50 ft of valley):
- V‑valley 16 oz, 18″ x 10 ft:
-
- Need 5 pieces → 50 ft × $148 = $740.
- Includes minimal waste.
Medium Roof (~100 ft valley):
- Use mix of 10‑ft lengths.
- 10 pieces at $148 each = $1,480.
Large Roof (>200 ft valley):
- Considering quantity discount:
- 20 pieces × ~$145 = $2,900
Add W‑valley cost if required. For same lengths:
- 10 pieces × $230 = $2,300
- 20 pieces × $230 = $4,600
Factors Influencing Copper Valley Flashing Cost:
Gauge (Thickness):
-
- 20oz copper costs 46% more per unit.
Width & Length:
-
- Wider valleys 24′, 36” cost more per unit.
Type (Profile):
-
- W‑valley is 50–100% more expensive due to rib shaping and material depth.
Order Volume:
-
- Lower unit costs can be achieved when larger orders are purchased.
Custom Fabrication:
-
- Tailored profiles add labor and setup costs.
Labor & Installation Complexity:
-
- Expect $6–$12 per linear foot for total flashing cost (all materials).
- Labor costs range from $40–$90/hour.
Geographic Factors:
-
- Freight charges may apply (e.g., delivery via skid/truck).
- Local copper pricing volatility.
Summary Table: Copper Valley Flashing Cost
Type & Gauge | Piece Price (10 ft) | Cost/Linear Ft |
---|---|---|
Standard V, 16 oz, 18″ | $148 | $14.80 |
Standard V, 16 oz, 24″ | $185 | $18.50 |
Standard V, 20 oz, 18″ | ~$217 ($148 ×1.46) | ~$21.70 |
W‑Valley, 16 oz, 24″ | $230 | $23.00 |
W‑Valley, 16 oz, 18″ case | $360 (10 pieces) | $36/ft per piece* |
Custom, 20 oz, 24″ | $450–$700+ (est’d) | $45–$70+/linear ft |
Case-packed pieces are sold per 10, not per single.
Real-World Cost Scenarios:
Installation for 100 Ft Valley with 16 OZ V Valley:
-
- Materials: 10 × $148 = $1,480

- Total: $2,280
Premium Build, 100 ft valley, 16 oz W‑valley:
-
- Materials: 10 × $230 = $2,300
- Labor/overhead: $10/ft × 100 = $1,000
- Total: $3,300
Custom Project, 100 ft valley, 20 oz custom W‑valley:
-
- Materials: 10 × $500 = $5,000
- Labor/overhead: $12/ft × 100 = $1,200
- Total: $6,200
Conclusion:
Understanding copper valley flashing costs helps you make informed choices between standard V valley, W valley, and custom solutions. Estimate installation costs at between $15-40 per linear foot depending on type and roof complexity – however initial costs will likely be higher but its long-term investment potential makes copper an appealing long-term choice for your roof.
