Everlast Group IR Inspection The Light, Leeds

Further to our IR survey, carried out on 26th August 2014, we take pleasure in providing our report in respect of the roof areas in question at this property. We trust that this information is sufficient for your purposes however please do not hesitate to contact us should you require further clarification or assistance. Everlast Specialist Surveys were instructed to carry out an independent Infrared roof survey in an attempt to establish the water content & ingress points within the roof system.


INTRODUCTION

Under instruction from Jenna Richardson of Colliers, a survey was carried out to the roof area at the Light Leeds on 26th August 2014. The purpose of the survey was to establish the moisture content within the roof.

The Everlast Group Specialist Surveys is fully certified in Thermal Photography, we have over ten years’ experience in non-destructive testing providing services to some of the biggest manufacturers and clients across the globe. We utilise our detection methods to help reduce costs on refurbishments, ensure correct installations for leading manufactures & damage identification. We carried out nondestructive testing using the following device:-

ThermaCAM® P60 Infrared Camera by FLIR

Thermography is a non-destructive type of testing and is an invaluable resource for determining roof performance and predictive maintenance. The camera can assess flat roofs for damaged insulation and entrapped moisture allowing building owners to make an informed decision to action any defects.


REPORT

PHOTO IR IMAGE

IMAGE 1 - The two hotspots shown on the thermal image are from previous equipment laid on the roof.

IMAGE 2 - The IR image show an area of saturation (Circled) the area is in close proximity to the neighbouring pipework, outlets & post penetrations from the plant supports.


IMAGE 3 - The general field area in the IR image is in good condition however the area to the top of the image is showing signs of saturation.

IMAGE 4 - This image is a close up of image Nr2. The insulation boards can be easily identified due to the volume of water they have consumed.

IMAGE 5 - This image is a close up shot of the area beneath the plant and also the gutter area.


IMAGE 6 - An almost reverse image of the previous one. Again saturation is present in the gutter area but the main volume of water is located beyond the gutter and under the plant.

IMAGE 7 - In the top left hand corner there is a white out area in the image, this is due to the emitted heat from the units.

IMAGE 8 - The dark patch (Circled) in the IR image is the core sample location from the previous destructive inspection carried out on 18/08/2014.


IMAGE 9 - The roof area in this image appears to be in good condition. The heat spot to the right of the image is emitted heat from the neighbouring unit.

IMAGE 10 - The area in this photo appears to be in good condition with no cause for concern.

IMAGE 11 - The area in this photo appears to be in good condition, the apparent heat spot to right of the image is emitted from the pipework.


IMAGE 12 - Due to the location of this image and the reflected heat emitted it is difficult to ascertain the condition of the roof using Infrared, we did however find using the troxler that this area is slightly damp in places.

IMAGE 13 - We believe that the heat spot on the above IR image is that of emitted heat from the extractor fan to the left.

IMAGE 14 - Continued but in reverse.


IMAGE 15 - The gutter area appears to be saturated. We noticed on our visual inspection that this location has received some remedial repairs in the past, these could have been the previous ingress points.

IMAGE 16 - Unfortunately the IR image came through as corrupt but we can however confirm from the troxler survey that this location is saturated. Please refer to the moisture content drawing.

IMAGE 17 - Due to the location of this image and the reflected heat emitted it is difficult to ascertain the condition of the roof using Infrared. We did however


moisture map this area using the troxler, please refer to the moisture content drawing.

IMAGE 18 - Continued.

IMAGE 19 - The image shows high saturation present. This is the area to the right hand side of the gutter, above screen 7. Please refer to the IR location plan.

IMAGE 20 - The image shows general area to be in good condition with very slight moisture within the system to the right of the image.


SUMMARY To help gain a thorough understanding of the inherent issues of water ingress and identify areas of risk to the existing roof membrane, Everlast Specialist Surveys were invited to carry out a comprehensive non-intrusive roof survey using Infrared technology. Prior to our survey we attended an informal discussion with the parties that are involved with the project to ascertain the nature of the works. After reviewing the readings taken using our Troxler 3216 Moisture Gauge in the areas requested, we proceeded to carry out an infrared survey. It soon became apparent that the two types of test results were accurate and conclusive. The images in this report have not only identified areas of trapped moisture within the system, they have clearly localized them to help narrow down the areas of further investigation or remedial repair work. During our inspection we identified a large area of saturation parallel to the problem gutter. This area is partially submerged under water and as a result was very difficult to get a true understanding of the severity of the saturation. The location of the ponding water is underneath some of the present plant and is therefore shaded from the sun and sheltered from the wind. In this situation the standing water is present for long periods of time, if the main cause of the leak is present in this particular area then all the ponding water is doing is creating a steady flow of water ingress. We hope this report is to your approval, however if you have any questions or queries please don’t hesitate to contact me. Please be assured of our best attention at all times. Regards
