Can you upgrade an existing roof?

An existing roof can be upgraded/refurbished but it is first necessary to establish a few key points that will have an impact on your final decision on whether to upgrade your exisiting roof.

We have prepared this guide for householder’s and homeowners with minimal roofing knowledge. By providing information on the design, materials, construction and maintenance of successful flat roofs; we hope it will assist you to a satisfactory completion with your roofing project.

An existing roof can be upgraded/refurbished but it is first necessary to establish the following:

  • Is the existing membrane adhered to the roof?
  • Is there any ponding on the roof?
  • Is the deck sound or wet?
  • Why has it failed?

If the roof is in good condition a single layer attached to the existing will extend the life of the roof.

If it is in poor condition the existing may need stripping off and a new RBM laid with insulation if it is over a heated area of the property. This is required under the Building Regulations.

If the roof is ponding, upgrading or applying a new membrane will not change the falls in the roof. This must be drawn to the attention of your contractor, who depending on the degree of ponding will advise.
