Feb 3, 2019

Replacing Old Roof Shingles with New Ones

When it comes to roof maintenance and repairs, one common question that homeowners have is whether they can put new roof shingles on top of old ones. The answer to this question depends on various factors, including the condition of the existing shingles, local building codes, and the type of roofing material being used.

Advantages of Installing New Shingles over the Old Ones

If your existing shingles are in relatively good condition and the roof's structure is sound, installing new shingles over the old ones can offer a few advantages:

  • Cost Savings: Installing new shingles over the old ones can save you money on labor and disposal costs associated with removing the old shingles.
  • Added Protection: Layering new shingles can provide an additional protective barrier against the elements, improving the overall durability of your roof.
  • Quicker Installation: In some cases, overlaying shingles can expedite the installation process, reducing the time your home is exposed to potential damage during the roof replacement.

Considerations and Limitations

While installing new shingles over the old ones can be a viable option, it's important to consider the following:

  • Roof Condition: If the existing shingles are severely damaged, warped, or have moisture issues, overlaying may not be recommended. It's crucial to assess the condition of your roof and determine if a complete tear-off is necessary.
  • Weight: Layering shingles adds extra weight to your roof. It's essential to verify whether the roof's structure can support the additional load, especially if the current roof already has multiple layers of shingles.
  • Building Codes: Local building codes may have specific requirements regarding the number of shingle layers allowed. Ensure that you comply with these regulations to avoid any issues in the future.
  • Warranty: Overlaying new shingles may affect the warranty of both the new and existing shingles. It's advisable to consult with a roofing professional to determine the warranty implications.
