Let’s face the facts: we are seen as experts. Customers expect answers from us, usually immediate answers. How tempting it can be to make them happy! Armed with our expensive, high-tech tools, it is all too easy to forget we can’t always come up with those answers.

Reports are an essential part of our work. The professional standards I mentioned last week give good guidance on what that report should look like, at a minimum. Manufacturers like Fluke have done a superb job of developing report writing software that not only makes life simple but also produces great looking reports.

One year ago I made some predictions about where I thought the market might be headed (click here to read full post). It is useful, I think, to see how today’s reality compares with yesterday’s dreams.

We are close, but thankfully not yet there. Sales of lower-cost systems continue to grow. This has [...]
I seem to have accumulated a short list of items each of which is too small to be a week’s posting by themselves, but all of which I wanted to share with you—thus the title of this week’s posting!
First: A follow-up to let you know that the ice on Joe’s Pond here in Vermont finally [...]
Last week, I went into detail on tips to help you prepare for a roof inspection by conducting a pre-inspection during daylight hours. Now, I will explain necessary steps to take while inspecting a roof in the evening, and what you can expect to see if there are issues.
Before you begin, it is important to [...]
Over the past couple of weeks we’ve talked about how low-slope roofs leak, the damage caused by trapped water, and the conditions needed to use thermal imaging to find it in the roof system. Many new thermographers ask me: “How can I safely and reliably get good results up on the roof?”
This vertical ladder [...]
Last week we talked about how low-slope roofs leak and, as a result, how the water becomes trapped in the roof system—generally in the insulation—accelerating roof failure. According to a survey by the National Roof Contractors’ Association, on average, roofs in the United States are replaced every ten years or less!
A penetration to the [...]
The snow is nearly melted here in Central Vermont. If you are responsible for the maintenance of those low-slope roofs under which we work and live in, this is a great time to get up on the roof and conduct a spring inspection. A simple walkover with an inspection checklist in hand can [...]
Last week we talked about emissivity and reflection, probably the two most talked about issues among thermographers. But that ain’t all we need to talk about! There is a reason engineering heat transfer courses are both long and notoriously challenging. We won’t go that deep into it, but as most of you know, I am [...]
This week’s Teaser Infrared Image is a good tie-in, to this week’s post from The Snell Group: Reflecting on Our Surroundings
