Can You Install Metal Roofing Over Shingles? Things To Consider
November 13, 2023

If you’re a homeowner, there’s a good chance you’ve had to deal with roof repairs at some point. It’s a hassle. The cost, the mess, the disruption – all for something that seems to need replacing every few years.

But what if there was another way? Enter metal roofing. This cost-effective, eco-friendly, and long-lasting roofing option is becoming increasingly popular among homeowners. And the best part? You can install it right over your old shingles. Let’s dive in!

The Metal Roof Advantage

Can you put metal roofing on top of damaged shingles?

Absolutely! Installing a metal roof over existing shingles can save money by avoiding tear-off expenses. However, following specific installation methods is crucial to ensure a proper fit and minimize any telegraphing or inconsistencies from the old shingles.

How are the metal sheets installed over shingles?

There are a few methods, but the most common ones involve attaching metal panels directly to the shingles or using furring strips.

Metal Panel Attachment into Furring or Lathing Strips

One common approach is attaching wood purlins or sub-girts as furring strips on the old roof, which are then connected to the structure below. This framing system can be applied directly over existing shingles, decking, or underlayment. The new metal roof panels are then attached to the framing system.

Metal Panel Attachment Directly into Shingles 

A budget-friendly alternative is directly attaching metal panels through the shingles and into the underlying wood deck. Although it eliminates the expense and effort of using furring strips, it’s worth mentioning that steel can behave like a mirror, potentially revealing deck and shingle irregularities through the metal panels.

Shingle Recover Systems 

This offers an efficient alternative to traditional installation methods. Unlike asymmetrical systems, which demand a predetermined installation sequence, symmetrical panels can be installed or replaced in any order. This simplifies repairs, avoiding the need to remove perfectly good panels to reach damaged ones.

Do I need underlayment for a metal roof over shingles?

Indeed, a protective barrier between the existing shingles and the fresh metal roof is imperative for projects involving direct attachment. This shield plays a vital role in averting any potential wear or harm the shingles might inflict on the metal panels during their expansion and contraction over the roof’s long life.

Choosing the Right Installation Method

There are several ways to install metal roofing over shingles, including direct attachment and using furring strips. Each method has pros and cons, so it’s essential to consult with expert metal roof installers to determine the best approach for your home.
