Thermal imaging Part 3: How much does thermal imaging survey cost?

How much will a thermal imaging survey cost us?

By far this is the most popular question that our customers ask.

You may want to have an infrared survey carried out for a variety reasons. Your objective may be to discover and diagnose energy efficiencies or to detect and inspect property defects. Whatever it is, with a tight budget in hand, you want to know that you are getting value for money and that it is well spent. Our aim is to make sure you make informed decisions.

After looking at thermal equipment and science in Part 1 and understanding colours in Part 2, let's continue our thermal imaging education journey and look at the pricing and what is involved.

Pricing is based on two main elements: 1) the required time on your site conducting the survey and 2) subsequent analysis to deliver your project. We briefly consider each element.

 

 

Time conducting your thermal imaging survey

The first element of a thermal imaging survey cost is the survey time. Typically our certified thermographers will spend up to nine hours on site over a total 18-hour period, enabling both daylight and night time surveys of your property envelope. This thermal imaging survey of the building means visual and thermal images will be included in your report. This will allow easy identification of defects that you can subsequently instruct to get rectified on site.

As survey days are focused on time, multiple buildings can be surveyed very cost effectively. The price you pay is for the day spent surveying rather than the number of buildings. Therefore, this allows to survey as many buildings as you require within the time frame at no extra cost to you.  

 

Time analysing your thermal images

The second element of a thermal imaging survey cost is the image analysis. Once your buildings have been surveyed, the next stage is to analyse and quantify your thermal images. Analysis time is charged at a daily rate and typically takes twice as long as the thermal imaging survey time. One full day on site usually equates to at least two full analysis days although this does vary depending on the deliverable.

Roof and elevations together with the IRT eDash may, for example, require four days or more in our qualified analysts to carry out the work depending on the size and complexity of your buildings.

 

What else may be charged for?

Some companies may charge you for travel and expenses. At irt surveys, because we've got the UK covered, this charge does not apply.

Another additional cost you could be charged for is the hire of equipment such as cherry pickers in situations where access is impossible without an elevated platform.

These items should always be brought to your attention and quoted ahead of any purchase order being submitted.

 

A final word of warning

When it comes to thermal imaging pricing, there are no such thing as a stupid questions.  It is essential that you are aware of all the pricing elements and that these are clearly explained to you. Do ask as many questions as you need to until you are satisfied with the answers you are given. Get several quotes and make sure that you choose a reputable company renowned for impartiality and expertise.

Five Common Flat Roof Defects To Be Aware Of

Five Common Flat Roof Defects To Be Aware Of

When it comes to flat roof defects, how many of us go about our day-to-day lives with a problem quite literally hanging over our heads?

Chances are, if your building is topped off with a flat roof and you haven’t had it checked recently, you are one of them.

Flat Roof Construction

Flat roofs offer many advantages for building:

  • they can help keep the interior warmer by absorbing sunlight at a higher rate than slated roofs.
  • they are ideal for solar panel installations.
  • they can often be the most economical option for construction.
  • they are quicker to install than other traditional roofing methods.
  • they are also more accessible, allowing for easier inspection processes.

Flat Roof Defects

Unfortunately, however, property owners too often adopt the old mantra of ‘out of sight, out of mind’ when it comes to what’s above their heads – and this is particularly problematic with flat roofs.

More than any other style, flat roofs need to be monitored regularly since there is no way for water to naturally filter away. It doesn’t need to be problematic but when problems do not visually present themselves on a daily basis, it’s easy to take your eye off the ball.

With this in mind, let’s take a look at five of the most common flat roof problems and what they could mean for your property.

Flat roof defect 1 – Standing water

This is one of the primary causes of flat roof leakages. Water will start to damage your roof’s material if it does not drain or evaporate within 72 hours and that means regular inspection is particularly important during winter and spring months. The problem is usually caused when there is insufficient drainage or the roof itself is just too flat. Despite the name, there should always be a small amount of slope for effective drainage. Snow build up can also be problematic as snow and ice can block drains and gutters.

Flat roof defect 2 – Blistering

Even small amounts of trapped moisture can result in your flat roof membrane detaching from the layer below and cause roof ‘blisters’. This is the most common roofing problem and it tends to get worse during the day when the heat of the sun causes the trapped moisture to expand. When blistering occurs it is vital to identify the source of the moisture.

Flat roof defect 3 – Thermal movement

Repeated cycles of heating and cooling cause flat roof materials to expand and contract. Materials must be equipped to deal with these movements without cracking under the pressure to avoid water penetration.

Flat roof defect 4 – Exposed layers

Taking all a British winter, and sometimes summer, has to throw at you isn’t easy. Throw continual roof traffic (accessibility has its downsides) into the mix and it’s only natural that, over time, your roof’s protective layers will suffer a bit of wear and tear.

Flat roof defect 5 –  Poor quality flashing

Given the importance of drainage on a flat roof, it’s vital to regularly inspect the condition of the flashing. This is used to prevent water from penetrating a junction and problems can occur when it has been poorly installed or damaged and bent over time.  Flashing damage can also be caused by fungus growth from moisture build in problem areas pushing away flashing.

These are only five flat roof defects most commonly encountered. They overwhelmingly highlight the need for certainty in terms of refurbishment.

That’s why an increasing number of organisations are using infrared thermography to assess their properties which can reveal exactly where and why problems are occurring.

With the summer weather on its way, there is no better time to carry out flat roof inspections. With our state of the art technology, we can

  • pinpoint the exact location of trapped moisture within the roofing system,
  • determine ingress points,
  • and tell you how much it is costing.

In addition to this the IRT Commercial Envision report can provide you with a list of refurbishment options with potential savings in £s, kWh and CO2. This information can be used to build a powerful case to leverage grants and budgets.

We have helped many organisations save £000s on their flat-roof refurbishment. Contact us now to find out how you can do the same.
