Can I put rolled roofing over shingles?

It is generally not recommended to install rolled roofing over existing shingles. While it may be possible to do so, it can lead to several issues that may compromise the integrity and effectiveness of the roofing system.

Here are some reasons why it is not advisable to install rolled roofing over shingles:

  • Added weight: Installing a new layer of roofing material over existing shingles will add extra weight to the roof structure. This can cause the roof to become overloaded and potentially lead to structural damage.
  • Uneven surface: Shingles may have different heights due to wear and tear, and this can cause the surface to be uneven. This can make it difficult for the rolled roofing to lay flat and adhere properly, which can lead to leaks.
  • Trapped moisture: Moisture can become trapped between the shingles and the rolled roofing, which can lead to mold growth and rot.
  • Reduced lifespan: Installing a new layer of roofing material over old shingles can reduce the lifespan of the new roof. This is because the new roof will not be able to breathe properly and may be more susceptible to damage from weather and other external factors.
  • In general, it is recommended to remove the old shingles before installing rolled roofing. This will provide a clean surface for the new roofing material to adhere to, which will improve its lifespan and effectiveness.
