Can Metal Roofing Be Installed Over Shingles? Quick Guide


Can metal roofing be installed over shingles? This is a persistent question for those who want to enjoy all the benefits of metal roofs without spending too much money replacing their current shingle roof.

The good news is that the answer is yes. There are countless benefits of installing a metal roof over shingles, and there’s no need to remove the old shelter. Because metal is lightweight, it’s ideal for installing over an existing cover.

However, there are some considerations that you should keep in mind to ensure that this procedure is done correctly.

Before Starting…

If you decide to put a metal roof over shingles, consider the quality of the top from the planning stage. A trustful Industrial Roofing Company like IPE Internationa will highlight the importance of safety, as the shingles must be in good condition to install a metal roof over them.

For example, ensure the plywood on your shingle roof is in excellent condition and free of holes and soft spots to minimize safety risks in extreme weather conditions.

On the other hand, remember that a metal roof will be installed correctly and drilled with the help of screws. Hence, checking the foundation layer on which it will be installed is indispensable.

How Is It Done?


There are two defined methods for placing metal roof sheets over shingles.

The basic process is to implement a new subfloor over an existing tile roof; this way, the new layer will cover the old tiles.

This new layer will act as a defense when water enters the roof. It also acts as a buffer between the two layers, as the coating protects the shingle granules if they start to wear away.

The second method involves the installation of metal roofing with purlins or battens. The purlins are drilled down to the roof deck based on the metal roof construction. It is then attached to the purlins and provides a flat surface to place the metal roof panels without the grooves and blemishes of a shingle roof.

What Are The Main Benefits?

Installing a metal roof over shingles is cheaper than a total replacement and would offer many benefits. For example:

  • It is durable and resistant as a properly screw-drilled metal roof will last for over 40-50 years before needing replacement.
  • It is naturally waterproof and withstands extreme weather conditions, such as high winds and the intense UV rays of the summer sun.
  • Metal roofs are low maintenance and generally require less frequent inspection or industrial roof restoration processes due to their strength and quality.
  • Many people also prefer metal roofs due to energy savings. The unique metal cladding reflects and absorbs heat instead of absorbing it, providing a cooler summer temperature.
