Most homeowners consider dumping their asphalt shingles with the intent to enjoy the benefits of metal roofing. However, they probably don’t know installing a metal roof over shingles is a viable and eco-friendly option, providing your roofing with an extra protective layer while saving the cost of removing the old roof. You might wonder, “is this a good idea to install a metal roof over existing shingles, and what are the other considerations for doing so?” We have enlisted everything about this in this article to help you make an informed decision about installing metal roofing over shingles. Inspect your existing roof from the best roofing companies in Pasadena to evaluate the roof’s prevailing situation since it may influence this task.

Common Residential Roofing Materials: Asphalt And Metal!

Before we discuss whether you can put a metal roof over an asphalt roof, you need to be acquainted with both.

Asphalt Shingles:

3-tab, dimensional, and luxury are the three types of asphalt shingles. While 3-tab shingles used to monopolize the roofing market, dimensional shingles are now the most often installed variety on roofs. Luxury-style shingles are just as highly advertised as dimensional shingles, but they cost nearly twice as much.

Metal Roofing:

Metal roofs are of two types: standing seam and screw-down panel. A standing seam metal roof system is made up of panels series joined together at the seams or mechanically seamed, allowing the panels to expand and compress freely when the metal heats up.  A screw-down panel is just exactly what it sounds like: it’s screwed down. The screws are screwed through the metal panel, leaving no space for expansion or contraction. Due to its lack of extension capabilities, installing a screw-down panel over a hot space such as your house or office isn’t advisable.

Also, engage an insured, certified, and experienced roof contractor in Downey to undertake this type of roof replacement.

Can You Install Metal Roof Over Shingles?

The straightforward answer to this question is YES. Installing a metal roof over shingles can be feasible, although it depends on the existing roof’s condition. With the intent to make this accomplishment, your current roof should be near its lifespan and must be in its pristine condition (no sign of lifted or cracked shingles, blisters, or bumps). Most roofs won’t be excellent options due to the wear and tear they endure during their lifetimes. Hence, it’s imperative to get your roof inspected annually by professionals for any signs of roof replacement or roof repair in Long Beach.

The project may be hassle-free if the new metal roof is installed properly and your local roofing contractor handles everything correctly. You may save up to 25% on labor expenses by avoiding taking off your old shingle, installing new underlayment, or paying disposal fees for the old roofing materials.

Necessary Steps To Take Before Installing Metal Roof Over Shingles

You should follow these measures while trying to save money on the pre-installation of your metal roofing over shingles.

  • Remove air vents, pipe flashings, or any other obstructions
  • Repair broken, torn, or cracked shingles
  • Clean the roof and eliminate any debris that may pose a problem
  • Inspect any roof leaks or cracks that may cause additional harm if not corrected before installing the roof
  • Contact your local building codes to ensure this project can be accomplished
  • While many regions permit re-roofing over one layer of shingles, others allow re-roofing over two shingle layers
