Several types of roof-monitoring equipment are available to roofers, including those used for predictive monitoring. Predictive monitoring can be installed under the roof, on the roof, or both. The former involves measuring pressure physically, while the latter involves using an aerial monitoring system to measure the roof from a high vantage point. Here are a few common applications for predictive roof monitoring.
A good thermographic inspection program will include periodic IR roof checks to detect leaks or other potential problems. By identifying moisture hidden beneath a roof, IR can help prevent tear-offs. It produces maps of roof status that can be included in reports on roof condition. An infrared professional will interpret the maps and create an action outline that will help the building owner plan the cost of repairs and the life of the roof.
Thermography is the process of measuring heat. Infrared light reaches an object six feet above its surface, so it picks up energy wavelengths that produce heat. Infrared imaging captures these signals and shows the source of the heat. It is an invaluable tool for predictive maintenance and condition monitoring. Infrared cameras are non-invasive and non-destructive. The images produced by thermography are highly accurate, so they are an important tool in detecting leaks in roofing systems.
Vibration is generated when a piece of machinery or equipment is operating. Vibration measurements can reveal a variety of problems including misaligned components, load asymmetry, and damaged bearings. Vibration monitoring is part of a predictive maintenance program that identifies issues before they become costly. In addition to detecting failures, it can also help detect early signs of damage. Roofing systems are no exception.
The maximum value of vibration is called its amplitude. This is measured in mils or inches per second. It is the best representation of the true energy that is produced by a machine. Most vibration-monitoring programs collect data from the bearing cap or housing of the machine and then transform it into a time waveform. Peak velocity values are used with vibration data between 0 and 1,000 Hz and are interpreted using a microprocessor-based frequency-domain system.
Sensors for predictive monitoring in roofing systems work by sensing snow and other pressure from the roof surface. The system can predict when roof damage is likely and recommend repairs before damage occurs. Predictive monitoring is ideal for climates with lots of snow or ice. During harsh winters, sensors on a roof can detect ice buildup and detect the severity of the damage. They can also monitor the moisture content of the roof to determine the level of risk.
Building envelope inspection
Whether you have a single-story office building or a multi-story complex with a variety of structures, you can benefit from the benefits of building envelope inspection and predictive monitoring. These services can help you assess the state of your building’s envelope, including its roof system and walls. They can also assess the condition of production processes, such as plumbing and HVAC systems. Before beginning your building envelope inspection program, you should assess the specific needs of your building.
When a building’s envelope is not properly maintained, it can contribute to a variety of issues. For example, it can be prone to air leakage, especially between exterior wall assemblies. This influx of air leads to higher energy bills. Moisture is also a common problem. When hot and cold air meet, condensation occurs. Building envelope inspection can help identify issues in these areas, including moisture problems and incompatible specifications.
The benefits of predictive maintenance are numerous. It can predict when repairs are necessary and save money in the long run. Some companies have been able to save thirty to forty percent by implementing predictive maintenance in their roofing systems. Other companies are saving eight to twelve percent every year, while others are seeing up to fifty percent in savings. But how can predictive maintenance benefit roofing systems? To maximize its benefits, it must be implemented with higher management.
The first step in implementing a predictive maintenance program is identifying potential sources of water penetration. Buildings that regularly experience water damage are more susceptible to the development of mold and other issues that cause a facility to become unhealthy. A facility manager can reduce risk and save money by using predictive maintenance. If a roof is in need of repairs, predictive maintenance can help prevent damage. If water penetration is a problem, a building manager can implement a preventative maintenance program. The benefits of predictive maintenance programs are numerous, and it is important to choose the right one for a particular situation.
