Can You Install Metal Roofs Over Other Materials?

Before installing a metal roof, many homeowners wonder if the new roofing materials can be installed over their existing shingles. The answer, surprisingly, is "yes." You can safely put a metal roof over your old roofing materials at your home.

You can do this because metal roofs do not add much weight to an existing roof. In fact, a lot of contractors actually like doing this instead of removing an old roof before installing a new metal roof.

Advantages of Installing Metal Roofs On Top of an Existing Roof

Can You Install Metal Roofs Over Other Materials?

There are several advantages to installing a new metal roof over an existing roof, particularly if the existing roof is a shingled one. Here are some of these advantages:

  • This helps increase the R-value of your roof – Having an additional layer of protection underneath your metal roof, even if your old shingles are not in perfect shape, actually increases your roof’s thermal resistance. The extra layer makes your home more energy-efficient.
  • It helps you save money – By avoiding the tear-off costs on the old roof, you save money. You also don’t have to spend money hiring a junk hauler to dispose of the shingles removed from your roof.
  • It adds another layer of protection – If an unusually strong storm comes along and blows off your metal roof, or dents it heavily with hail, you still have your old roof underneath to offer additional protection.

Before you give the "thumbs up" to this plan, there are a few considerations that need to be made. You will need to ask your local homeowner's association if this can be allowed for your home. The structural integrity of your old roof will have to be checked even though metal roofs are lightweight.

The materials to be used for attaching your metal roof to your old roof will also need to be considered. Longer screws and nails will be needed to securely attach your metal roofing to the roof deck under the shingles. If there are no screws or nails long enough to achieve this, removal of the old roof may be inevitable.
