Refurbishment of Failed Flat Roofs
Maximise your Investment with the Right Waterproofing Solution

The refurbishment of a failed flat roof is the most common waterproofing problem that the building industry is coming across. Taking all the variables into consideration when specifying a waterproofing solution is not an easy process.

Here are a few steps to consider when undertaking a roof refurbishment project:

STEP 1 Diagnose the problem

Setting the scene
Water ingress due to failure of the roof components or due to the shortcomings of the roof construction can have a dramatic effect on the building occupier, resulting in water ingress and the loss of thermal performance of the insulation material (if any insulating is installed).

In addition the financial burden associated with the roofing works necessary to reinstate the integrity of the roof waterproofing can be significant.

Diagnosis of the problem may not be straightforward. Water could be collecting within the roofing layers due to several reasons.

  1. Poor perimeter detailing/failure at upturn
  2. Failure of the outermost weathering layer
  3. Inadequate & poor detailing around penetrations
