Can metal roofing be installed over shingles?

Yes, metal roofing can be installed over shingles in many cases. This option is popular among homeowners looking to save time and money on the installation process. However, there are a few important factors to consider.

Cost-Effective Option

Installing metal over shingles eliminates the need for removing the old shingles, which can save on labor costs.

Faster Installation Time

The metal roof can often be installed directly over the existing shingles, reducing installation time.

Added Protection

The shingles can provide an extra layer of insulation and help with noise reduction.

When to Remove Shingles Before Installing Metal

Poor Shingle Condition

If the shingles are damaged, curled, or have multiple layers, it’s best to remove them first to ensure a solid base for the metal roof.

Local Building Codes

Some areas require that the existing shingles be removed before installing a new roof.

Weight Concerns

Adding a metal roof over shingles can be heavier than the structure can support. It’s important to consult with a professional to ensure the roof is properly supported.

How to Ensure a Quality Installation

Hire a Professional Roofing Contractor

A professional can assess your roof’s condition and determine if installing metal over shingles is appropriate.

Ventilation is Key

Proper attic and roof ventilation is crucial when adding a layer of metal roofing over shingles. It helps prevent moisture buildup and other potential issues.

Inspect Existing Structure

Ensure that the roof deck, framing, and support structure are in good condition before adding a new layer of metal roofing.
