Installing over
Existing Roofing

How to install your new vinyl roofing over an existing roof

Removing an existing roofing system can be costly and time-consuming. Luckily, when installing a new DEC-K-ING Roofcoat, it is not always necessary to remove existing materials, leading to significant cost and time savings on your roof project.

    • Very lightweight roofboards can often be laid overtop existing roofing systems.
      DEC-K-ING Roofcoat is then mechanically fastened, through to the substrate, for a watertight finish.

Please contact us about your roofing project and we will be happy to offer a solution that works best for you.
