A thorough and accurate regime of professional roof inspection basically pays for itself, as by spotting damage or problem areas early you can potentially save thousands of pounds. The price of a roof survey pales into comparison when considered against costly roof repairs and the associated fees you’ll shell out to deal with water and wind damage. But to make sure you get the most out of your roof survey it is important to know which kind of survey you need.
There are a range of different roof surveys available, and each has their own specific set of specialities and criteria. So below you’ll find our comprehensive guide to the roof surveys offered by Roofing Consultants, enabling you to determine which type is right for you.
Visual Roof Survey
As the name suggests a visual roof survey involves a physical examination of your roof by a human inspector. If your roof can be accessed safely then we are able to send up a qualified roof surveyor to photograph and inspect your termination details, rainwater gutters and all roof coverings in a more hands-on fashion than automated equipment offers.
Extended Camera Survey
If your roof is located at an average height but fragile roof coverings prevent a visual survey, then an extended camera survey can provide just as thorough an inspection. This simple process involves an inspector using long camera masts to photograph problem areas, and as such you avoid the associated paperwork, scaffolding and disruption a more intrusive inspection requires.
The use of a Mobile Elevating Platform survey becomes necessary when commercial roofing systems are located at prohibitively high levels which prevent safe human access via ladders or access hatches. Inspectors can gain access using a MEWP to roofs up to 100m high, and are then able to document and inspect the site as they would in a typical visual roof survey.
Drone Roof Inspection
For excessively high roofing systems or those which are unsafe for humans to traverse, the Drone Roof Inspection offers an efficient alternative to a human visual inspection. With no scaffolding, ladders or paperwork required, a drone can survey several locations in the time it takes a human to inspect just one area of roofing. The high quality footage obtained of your roof can then be viewed by professionals to determine your roof’s condition.
When a roof is suspected of retaining moisture the most effective and least invasive method of identifying problem areas is to undertake a core sampling. Specialist cutting tools are used to extract small samples of your roof neatly and precisely, with the tested areas made watertight and sealed immediately post-test. This method enables us to fully identify where and why your roof is retaining moisture, and therefore provide a much more comprehensive solution to the problem at hand.
Thermal Roof Survey
One of the best ways to initially detect trapped moisture in a roof prior to a core sampling is to use a thermal roof survey. Thermal cameras use infra-red technology to identify leaks, poorly insulated areas, and trapped moisture without needing to intrude into your roof’s structure.
Electronic Leak Detection
Roof leak detection can sometimes be invasive and intrusive, but with Electronic Leak Detection equipment we are able to swiftly locate the areas water has entered your roof using precision technology. A roof inspector can locate leaks in roofs and membranes using electronically charged bristles in an extremely swift manner, and without the use of flood testing or any other damaging techniques. Problem areas are then marked using survey paint, enabling a comprehensive repair plan to begin.
Moisture probes are used after leaking areas or water retention has been detected in your roof. A small area of roofing is exposed and a probe is inserted to test the amount of moisture in any given area. We employ this technique when we need to identify which specific areas of a roof have suffered damage, as it can be the case that only certain areas require repair as opposed to an entire roof replacement.
Moisture scanning is used as an alternative moisture detection method when your roof sits atop a building which is rarely heated, contains sources of heat at roof level, or your roof surface comprises of chippings. In these situations an infra-red thermal survey may not provide accurate results, so instead we employ a mobile non-destructive scanner to analyse your roof’s moisture levels and in turn provide you with the most relevant solution to your roofing trouble.
