Failed Flat Roof System

Visual Perspectives were commissioned by a leading roofing company to assess the condition of this 5,800m² flat roof at Space Studios Manchester. The client had a project planned to increase the U-Value of the roof and wanted to know specific areas of saturation with a plan to cut out and replace before the overlay project commenced.

The original proposal was to strip back the entire roof to the deck however, due to committed filming schedules; minimum disruption became a defining factor. We identified that only 12% of the roof was saturated that saves on project costs, reduced time and a reduced disruption to the building day to day operation.

We also used Photogrammetry to map the roof and produce a report with measured areas of water ingress.

Why do we use a Thermography?

Put simply, is shows us what the naked eye can’t see.
During the daytime, any moisture that has penetrated the roof system will heat up. After sunset, the surrounding areas that are dry, will cool down quickly whilst the water will retain its heat and start to radiate. The method shows up clearly the areas in the roof that are holding water to assist in tracking the leak to the penetration or for general condition analysis.
We always recommend follow up core samples are taken to confirm diagnosis.

Fast and Cost Effective Benefits

Time: VP had the resources to complete this project in 1 day, to include daytime visuals, followed by matching evening thermal images. 2-3 days later the client received a detailed analysis report indicating all defective areas including the Photogrammetry map with measured saturation areas. The client followed up with confirmed core samples.
Cost: Each project varies but on average £1800 per standard roof.
