Preventative Roof Maintenance
                                                  
Periodic roof maintenance plays an important part in the life of your roof system. When a maintenance program is properly executed, it will add years of service to the roof by detecting minor problems before they become major, as well as providing better protection for your building. Although best initiated when a roof is designed and installed, a preventative maintenance program, in most cases, can be implemented at any time and extend the service life of your roof.       

Patch and Repair  

As your building ages, the abuse it experiences from weather, movement, modifications and traffic may cause problems and destroy the integrity of your roof system. The roof membrane and flashings could blister, split, and/or tear. Although not severe enough to warrant a large project, they do threaten the system's integrity and need to be repaired promptly. We have specialized crews trained in roof maintenance and repairs ready to serve our customers.

Roof Information Management

Through the expertise of our staff, we inspect the condition of your roof system as well as its components and record them in a roof management database. With this information, we are then able to identify areas that need attention, make recommendations and prioritize tasks based on available budgets.       

Inspection and Analysis

Visual inspections and surface repairs may not be enough and a comprehensive analysis of your roof may be required in order to fully evaluate its condition. Core samples and infrared moisture detection can be done to determine the internal condition of your roof system.

Infrared Basics

Infrared radiation is electromagnetic radiation whose wavelengths are greater than those of visible light but shorter than those of microwaves are.

In its most familiar form, it is radiated heat which can be sensed by our skin, yet cannot be seen by our eyes. All objects, whatever their temperature, emit infrared radiation. The intensity emitted depends upon the fourth power of the absolute temperature of the object. It also depends upon a material property of the object, termed “emissivity”. An ideal infrared emitter, said to be a “blackbody,” has an emissivity of unity. Most real objects have emissivities less than unity, and therefore emit less intense infrared radiation than a blackbody at the same temperature. In summary, the infrared emitting properties of an object are characterized by its temperature and its emissivity.

Camera Technology
Infrared cameras historically used sensors made of exotic materials that required cooling with liquid nitrogen to a temperature of -320°F. A technology breakthrough achieved through military research now makes possible the production of uncooled high performance detectors capable of sensing and measuring infrared energy. Fueled by the commercial availability of this new uncooled technology, significant opportunity in the application of IR technology has emerged.

Roofing Inspection:

Infrared inspection of this commercial roof reveals water saturation due to leaks or condensation under the roof membrane. The heat generated by sunlight dissipates much slower where moisture saturated insulation exists. After nightfall, a slight temperature difference will exist between the dry insulation and the water-saturated insulation that can be seen with a highly sensitive infrared camera.
