Commercial roof inspection cost based on inspection type
Table of Contents
ToggleThe average roof inspection costs vary mostly based on the inspection type. Let’s break it.
Basic Physical Roof Inspection
The most common type of inspection is basic visual inspection. A professional conducts this on-site walk-through inspection to find leaks, cracks, pooling water, membrane damage, and general wear. It does not rely on any equipment but the expertise of the conductor. The cost of the basic inspection is $90 – $260. It is suitable for routine maintenance, identifying surface-level damage, and assessing general roof condition.
Drone Roof Inspection
This method is a bit expensive, and the cost ranges from $180 to $450. A high-resolution drone flies over the roof and captures aerial images and videos to assess the condition without physically accessing. It is suitable for large buildings, multi-story properties, or hazardous conditions where manual inspections are unsafe. However, this method is not suitable for hidden moisture or insulation issues.
Infrared Roof Inspection
Infrared roof inspection fixes the moisture problem with drone inspection. It uses thermal imaging cameras to detect temperature variations on the roof’s surface and identify trapped moisture, heat loss, insulation problems, and hidden leaks. The cost of this inspection is $350 – $680. This method is perfect for detecting water infiltration, insulation inefficiencies, and hidden leaks.
Moisture Testing
This is an expensive inspection suitable for the costly roofing project. The method includes core sampling, capacitance meters, or nuclear gauges to measure moisture levels. The cost ranges from $500 – $1,500. It confirms hidden moisture damage, identifies water intrusion points, and determines if a roof requires major repairs or replacement.
Free Roof Inspection
Many roof contractors offer free inspections for their promotion. These inspections are basic and cost nothing. It is suitable for initial roof condition assessment and seeking multiple estimates to pick the best one.

Roof Age & Condition
Older or deteriorating roofs often need more time and effort for thorough inspections. Extensive damage or leaks require additional testing as well.
