Installing Bellaforté Tiles Over An Existing Asphalt Roof

DaVinci Bellaforte Fake Slate TilesIf you are familiar with our lightweight roofing materials, then you probably know that we recommend a clean, smooth flat surface to start with for installation of our products.

As well, if you are familiar with roofing products, then you know that asphalt shingles, for example, can be laid on top of more asphalt shingles. In fact, this practice is so common that sometimes you can have multiple layers of asphalt shingles on a roof, occasionally more than are permitted.

While we recommend that our Bellaforté Tiles are installed on a smooth flat surface like our other shingles, in some circumstances, overlaying our Bellaforté tiles over one layer of Class A fiberglass asphalt shingles is an acceptable alternative.

In order for this type of application to be acceptable, we have specific recommendations in our Bellaforté Installation Guide for:

  • Preparation
  • Fasteners
  • Rake Edges/Gable Ends
  • Flashings

 

How does the ability to lay Bellaforté lightweight roofing tiles over a layer of existing asphalt shingles help you?  Well, it means that you don't have to pay for the removal labor or haul away of that layer of shingles, which means that it saves you money.

To learn more about the installation of our Bellaforté tiles, please feel free to reference our Bellaforté Installation Guide.

  1. Can you please provide additional installation details regarding the asphalt overlay installation method? For example, in the special issues section you state, “All fashings must be new and cannot just be caulked, cemented, or resealed. This includes, but is not limited to, valleys, step, pipe, vent, etc.”. Does this mean that the metal flashing in the valleys, which is underneath the asphalt shingles as a closed valley, needs to be replaced? Also, the step flashing on a brick chimney is under the asphalt shingles and, again, would this flashing need to be replaced? Further installation details for asphalt overlay would be greatly appreciated. Thank you, Tyler.
