Installing a Metal Roof Over Shingles

Installing a Metal Roof Over Shingles

When considering a roofing upgrade, many homeowners ponder the feasibility of installing a metal roof over existing shingles. This method has gained traction due to its perceived cost-effectiveness and the allure of a long-lasting metal finish. However, like any significant home improvement, there are pros and cons to weigh. In this guide, we’ll delve deep into the intricacies of this roofing method and provide insights to help you make an informed decision.

The Underlying Challenge: Deck and Framework Assessment

One of the primary challenges of overlaying a metal roof on shingles is the difficulty in evaluating the condition of the underlying deck and framework. A metal roof, by its nature, places additional stress on the framework. Without a meticulous inspection of the existing substructure, the roofing project can be set up for failure. It’s imperative to ensure that the substructure is robust and adheres to local building codes.

Weight Considerations: Metal vs. Shingles

A metal roof inherently weighs more than its shingle counterpart. This added weight can be a concern, especially for structures originally designed to support lighter shingle roofs. Before embarking on such a project, it’s crucial to engage roofing contractors, like Collins & Son Roofing, to conduct a comprehensive evaluation. This ensures that the structure can withstand the added weight without compromising its integrity.

Hidden Dangers: Overlooking Existing Damage

Overlaying a metal roof on shingles can inadvertently mask pre-existing damage. If the current shingles are deteriorated or damaged, these issues can remain hidden, only to manifest later, leading to potential leaks or structural problems. It’s essential to ensure that the existing roof is in optimal condition or to address any issues before proceeding with the metal overlay.

Moisture Traps: The Risk of Condensation

Layering roofing materials can inadvertently create pockets where moisture accumulates, leading to condensation. This trapped moisture can foster mold and mildew growth, which in turn can cause wood rot and compromise the home’s structural integrity. It’s vital to ensure adequate ventilation and moisture barriers to prevent such issues.

Warranty Implications: Ensuring Coverage

While installing a metal roof over shingles might seem cost-effective initially, it’s essential to consider the warranty implications. Some warranties might become void if the metal roof is installed over existing shingles. Ensuring that your installation method aligns with the warranty stipulations can save potential future headaches.
