How Do Commercial Roof Inspections Work?

Whether you’ve recently noticed some brown spots have appeared on the ceiling, or have seen water dripping from your roof, it’s time to take immediate action and get the problem fixed as soon as possible. We’ve put together an in-depth guide covering all you need to know about a commercial roof examination – from what it includes and how long it takes to the report and what this covers.

What Is the Purpose of a Commercial Roof Inspection?

A commercial roof inspection is a procedure in which contractors examine the exterior of your building to identify any problems. The process usually includes:

  • A visual inspection to determine if there are any signs of water damage, such as stains or leaks.
  • Checking for any missing shingles or tiles that may be causing an issue with water drainage.
  • Performing tests on the surface temperature of the roof to see how hot it is getting.
  • Taking a core sample. This involves removing a small piece of your roof to determine how many layers of roofing there are, the material of the substrate, the age of the roof, and the level of moisture.

How Long Does a Commercial Roof Inspection Take?


The amount of time a commercial roof inspection takes depends significantly on the size of the property, the number of roof sections, and the different types of roofs. On average, however, it should take between 30 minutes to 1 hour to carry out a commercial roof inspection on a 20,000 square foot commercial building. Once the commercial roof inspection has been performed, you need to wait for the report.

How Long Does It Take To Receive the Report for My Commercial Roof Inspection?

You should receive the roof inspection report between 3-5 working days. However, this does vary and depends from contractor to contractor. It would be worthwhile asking about this before hiring commercial roof inspectors.

What Does a Commercial Roof Inspection Report Include?

  • The repairs needed and current deficiencies in your roof system with detailed explanations.
  • Repair or replacement options going forward.
  • A quote for the repair or replacement options.

Alongside the above-mentioned points, the report will include all the areas that are contributing to the leaks and any recommendations going forward. Options to repair, restore or replace your commercial roof. You’ll just need to repair your roof if there are only a few damaged areas, but you may need to replace it entirely if the remaining lifetime of your roof is predicted to be less than 2 to 3 years or the roof is less than 25% saturated. You will also be advised to replace your entire roof if the majority of it needs repairing.
