Frequently Asked Questions

Double roofing is a renovation method where a new roof is installed over an existing roof instead of completely removing the old one.

The existing roof does not need to be demolished and disposed of, double roofing can reduce installation time, disruption, and some of the costs associated with a full roofing replacement.

The additional roofing layer may also improve the building’s thermal insulation, helping reduce heat transfer and potentially improving energy efficiency.

Before installing a double roof, the condition of the existing roof and supporting structure should be assessed to ensure they are suitable for the additional roofing system.
