Can A Metal Roof Be Installed Over Shingles
2025-08-29
Many homeowners ask us, “Can we install a new metal roof over our existing shingles?” The short answer is: often, yes. This method, known as a re-roof, can save time and money on tear-off costs. However, it’s not suitable for every situation. At Yongcheng Xingye, we begin every project with a thorough inspection to ensure your roof structure can support the new system and that the existing shingles are flat, secure, and free of moisture damage.
A successful overlay installation depends on using the right materials and techniques. Our high-performance Metal Roof System is designed for durability and longevity.
Key product parameters include:
-
Material: 24-gauge Galvalume steel with a AZ150 coating for superior rust resistance.
-
Finish: Kynar 500® PVDF coating in a variety of colors, ensuring excellent fade resistance for decades.
-
Profile: Classic standing seam with a concealed fastener system for a clean look and enhanced weathertightness.
We use specially engineered battens to create a perfectly flat and vented substrate over the old shingles. This critical step prevents telegraphing (where the old shingle pattern shows through) and promotes airflow to protect the roof deck.
| Consideration | Over Shingle Installation | Traditional Full Tear-Off |

| Project Time | Faster completion | Longer process |
| Roof Deck Health | Requires a solid, dry deck | Allows for full inspection & repair |
| Warranty | Yongcheng Xingye offers a full warranty on qualified installations | Full warranty applicable |
Metal Roof System FAQ
What are the biggest advantages of a metal roof?
Metal roofs from Yongcheng Xingye offer exceptional longevity, often lasting 40-70 years. They are highly resistant to fire, wind, and impact, and their reflective properties can significantly reduce cooling costs in the summer.
Will a metal roof make my house noisier during rain?
No, this is a common myth. When installed with solid decking and proper underlayment, a modern Metal Roof System is no louder than any other roof type. In fact, many homeowners find the sound of rain on metal to be pleasant.
How much maintenance does a metal roof require?
A Metal Roof System is very low maintenance. An occasional inspection and cleaning of debris from gutters and valleys is typically all that is needed to keep it performing perfectly for decades.
