SIG Design & Technology look at intrusive surveys, what they are and why you should consider having one on your flat roof.
If you or your client are at all concerned about the condition of an existing flat roof, if it is leaking, if the roof coverings are coming to the end of their working life, or if you need to improve or upgrade your roof or the equipment housed on it, a roof survey is a valuable first step.
A professional roof survey from SIG Design and Technology is free, it can help you decide on how to deal with an existing roof, manage existing leaks and prevent future ones, and help you futureproof your roofs with improved drainage and insulation.
What is an Intrusive Flat Roof Survey?
An Intrusive Flat Roof Survey is a comprehensive survey of a flat roof which includes cutting into the roof build up, opening up the layers to inspect them.
Why would you need an Intrusive Flat Roof Survey?
A great deal can be learned from a visual inspection of a flat roof, but there are a number of reasons why your client may need an intrusive roof survey. These include:
Ensure a Professional Survey is Carried Out
By its nature, an intrusive roof survey involves interfering with the waterproofing of the roof. For this reason, it should not be carried out lightly, or without preparation and skill, but should be carried out by trained staff from a reputable company. With decades of experience in flat roofing and the backup of our parent company SIG Plc (a FTSE 250 listed company), you can be assured that the team at SIG Design and Technology has the necessary experience.
What happens on an Intrusive Flat Roof Survey?
About Core Samples
As part of the survey process the technicians may take some core samples on various areas of the roof. “Taking a core sample” is the process of cutting out a small section of the roof to expose the different layers back to the deck. Intrusive techniques such as core samples should not be carried out if the roof is still under warranty, as this may invalidate the warranty.
Core Samples are taken to
A technician will take several core samples across your roofs, in areas which will indicate in his or her experience, the state of the roof as a whole. For example, the technician may take core samples at high (ridge) and low (eaves) points in the roof, to determine if any insulation installed is flat or tapered. The core samples will be cut to avoid any potential ponding areas, and areas which appear to contain weak or damaged materials. This is to ensure that repairs to seal the core sample areas can be made effectively, returning your roof to its pre-survey state.
Results of an Intrusive Flat Roof Survey
On completion of the survey, our technicians will compile the results into a written report with photography and commentary, together with recommendations. A good roof survey will provide you with the information you need to make decisions on the future life of your flat roofs.
