Question: 1 / 400

What is the purpose of performing a "thermal scan" on a roof?

To activate the roof warranty

To identify moisture or insulation issues

Performing a thermal scan on a roof is primarily used to identify moisture or insulation issues. During this process, infrared cameras detect temperature differences across the roof surface. Areas where moisture is present typically retain heat differently than dry materials, allowing for easy identification of leaks or failed insulation. By pinpointing these problem areas, the scan assists in assessing the roof’s condition and informs necessary repairs or maintenance.

Other options, while relevant in different contexts of roofing and building maintenance, do not accurately capture the specific purpose of a thermal scan. Activating a roof warranty, visually inspecting exterior conditions, and estimating repair costs involve other methods or processes that do not leverage the unique benefits that a thermal scan provides in assessing moisture and insulation integrity.
