Can You Put Shingles on a Metal Roof?: 1 Minute to Understand the Pros and Cons

Installing shingles over a metal roof is technically possible, but it’s not commonly recommended due to practical and design concerns. Typically, shingles—especially asphalt or architectural shingles—are installed over a deck or solid substrate, not directly on metal panels. If your existing roof is made of metal, retrofitting it with shingles may lead to issues like improper ventilation, moisture buildup, and difficulty in securing the shingles correctly. Removing the metal panels first to expose the decking is the industry-standard approach if you want to switch to a shingle roof. As a designer, I always consider not only functional aspects, such as durability and performance, but also visual harmony and integration with the home's style. For clients seeking a thorough transformation or seamless upgrade, exploring versatile tools like a home designer platform can help visualize how new roofing choices impact the overall aesthetic and layout before any physical changes are made.

Tips 1:

Always assess the structural condition underneath your existing metal roof before considering replacement or overlaying with shingles. Proper inspection helps ensure long-term safety and lets you plan any needed repairs for decking and framing.
