Experienced Roof Consulting and Analysis

GBI provides expertise, methods, and tools for in-depth analysis and resolution of construction and damage issues. 


A forensic roof inspection will be performed to ensure that the roofers follow the correct method. The inspection will include a review of the roof's performance, sample collection, and visual assessments. 
The need for uncrewed aerial vehicles (UAVs) is expanding. Drones that leverage thermal camera equipment to detect heat, in addition to conventional video cameras, are seeing use in various scenarios. 

Wind Uplift Testing

​From Architects and Engineers to Roof Consultants and IR Thermographers.  With a team of Certified Professionals, you can be sure of the quality of work.

​Wind uplift is often overlooked as a problem because it isn’t always an obvious defect, but the repercussions can be just as costly as hail or mechanical damage to a roof system.


​Having an efficient estimate for your roofing materials is important. Not only will it help eliminate waste, but it will also ensure that you buy just enough for the roofing job.
