Frequently Asked Questions
Q1: What is the typical lead time for these copper shingle panels?
A: For standard sizes (20x16 inches), lead time is usually 15–20 working days after order confirmation. Custom orders may require additional time. Please contact us for exact scheduling.
Q2: Can these panels be used on steep roofs?
A: Yes, the dovetail interlock system is designed for roof pitches from 3:12 to 12:12. For steeper slopes, we recommend additional mechanical fasteners if required by local codes.
Q3: Do you offer any warranty on the copper shingles?
A: We provide a standard material warranty against manufacturing defects. Since copper is a natural material, its durability and patina development are not covered by a typical warranty, but we guarantee the panels meet the specified thickness and interlock performance.
Q4: How many panels are needed per square foot?
A: Each panel covers approximately 2.22 square feet of net roof area (accounting for overlap). Approximately 45 panels are required for 100 square feet (1 square).
Q5: Can I get a sample before placing a bulk order?
A: Yes, we offer sample panels (typically 12x12 inches) for a nominal fee, which is refundable for large orders. Please contact our sales team to arrange.
Q6: Are these panels compliant with building codes in the USA?
A: Our standard copper shingles meet ASTM B370 requirements, which are widely accepted in North America. We recommend verifying local codes, as some areas may require additional testing or specific installation methods.
Q7: What is the weight of a single panel?
A: Each 20x16 inch panel weighs approximately 0.9 kg (2 lbs), making it manageable for manual installation while still providing adequate mass for stability.
Q8: Do you provide installation instructions?
A: Yes, we supply detailed installation guidelines with each order. We also offer on-site training for large projects upon request.
