Accelerating development of datasheets to support roof repairs

Using an innovative and cost effective approach of drone photography to produce accurate drawings and maps of 50 roofs over 30 acres on a manufacturing site


The challenge of rapidly assessing all roofs on large site

The company has a large manufacturing site of over 30 acres with several buildings onsite including factories and warehouses. Across all the buildings there were over 50 roofs where contractors were required to carry out repairs. The customer required a permit system in place to safely manage and control contractors onsite and a method of providing them with a datasheet to inform them of the roof type, roofing conditions, safety systems and risks to be considered.


Using drone photography for visual inspection to map roofing data

One of the key challenges with this project was the verification of information from various datasheets, as these were required to aid the contractor to carry out their work. To use a roofing contractor to undertake the assessment of all 50 roofs would have been a long, slow and expensive process. Malone Group was engaged to accelerate the delivery of accurate information on the roofing systems, with an assessment of areas for concern and risks identified for contractors. The remit was not to undertake a structural analysis, so the emphasis was on a visual inspection.


In an innovative approach to the challenge, Malone Group commissioned drone photography of the site and roofing systems. This delivered significant cost savings to the customer and accelerated the delivery of an accurate drawing, mapping each roof using high resolution images and identifying the safety systems in place on each roof. Through a detailed analysis of all image data, it was possible to identify key areas for concern.


Accelerated production of approved datasheets within 3 weeks

Over 95% of roofs were fully documented in datasheets without any manual assessment required. A Roofing contractor was used to supplement this assessment process by operating a manual inspection by exception. As a result, it took just three weeks to get to approved datasheets for 50 roofs, which would have taken over one year to build using a conventional inspection and assessment approach.
