Infrared Moisture Surveys

Infrared thermography is a well established tool in diagnosing moisture within an existing roofing system.  Infrared imagery of a roof can be used as a method to determine the viability of coating and recovery options.  In addition, when looking at a roof replacement, infrared imagery can be used to target specific areas for removal leaving non-compromised insulation in place.  Defining project scope with infrared technology can result in significant savings to the owner by reducing labor, material and disposal costs.  Thermography is also useful in leak detection as the imagery often pinpoints the source of the leak.  Thermography is used as well in post construction quality assurance with respect to the entire building envelope.  Not only is it useful in detecting hidden moisture, but also in assessing the quality of air vapor barrier systems.  O'Brien Group has achieved CIT Level I from the Infraspection Institute.  CIT #12405

Infrared Moisture Surveys (cont)

During the moisture survey areas that are indicative of moisture are marked out with paint and any other roof defects are photographed and included in a written report.  The report includes a table quantifying the total square footage of wet insulation, as well as a CAD drawing illustrating where wet areas are on the roof.  

Roof Consulting & Assessments

We will perform a thorough, multipoint inspection of your existing roofing system.  This can be as simple is investigating one particular problem area, to inspecting all flashings, seams and details as well as underside deck condition.  Serviceable life of the existing system, remedies to existing problems along with cost estimates and possible replacement options if appropriate, are discussed along with budgets in a clear, and understandable report for decision makers.  Core cuts are performed to establish existing roof composition, assess the condition of insulation system, as well to confirm any suspicisions of moisture.  Specification and design assistance are also provided.

Quality Assurance observation

Rooftop Quality Assurance Observation is a service whereby a trained, certified, and knowledgeable individual provides daily observation and reports to the project team on a roofing project to help ensure the installation is performed in accordance with the contract documents and industry and manufacturer standards.  This service can greatly contribute to a quality roof installation by discovering construction defficiencies during construction versus afterwards when a roof failure can result in catastrophic losses.  A number of government agencies have realized great benefit of having  an RRO (IIBEC certified Registered Roof Observer), during roof construction and now require it in their specifications.  QA observation can add tremendous value to private projects as well.

QA Observation encompasses the following roof construction related items:

-Materials conformity to project specifications.

-Deck condition prior to installation.

-Material storage.

-Insulation attachement is in conformity with project requirements.

-Adhesive rates and usage are in conformance with manufacturer's specifications.

-Flashing details are in conformity with manufacturer's requirements for specified warranty term.

-Night tie-ins.

-Days worked, men on site and weather conditions.
