Commercial roof inspection
The National Roofing Contractors Association recommends inspecting roofs at least twice a year, ideally in spring and fall, and after any severe storm. A routine inspection typically costs $75 to $600, depending on roof size, access and whether moisture testing is included.
For a facilities manager, the inspection report is the cheapest roof decision you will make: it catches small repairs before they become leaks, and it gives you dated evidence for warranties, insurers and budgets.

$75 to $600
More for large roofs, infrared or core sampling.
What a proper inspection covers
- The field of the roof: punctures, blisters, splits, ponding and surface wear.
- Every seam, flashing, curb, penetration and pitch pan.
- Drains, scuppers, gutters and overflows, cleared and checked.
- Perimeter edge metal, copings and parapet walls.
- Rooftop units, their curbs, condensate lines and attachment.
- Inside: ceiling stains, deck rust and signs of past leaks.

Questions people ask
How often should a commercial roof be inspected?
NRCA recommends at least twice a year, preferably spring and fall, and after severe weather. Manufacturer warranties often require regular maintenance too.
How much does a commercial roof inspection cost?
Typically $75 to $600. Large roofs, difficult access and moisture surveys cost more.
Can our maintenance staff inspect the roof?
They can check from inside and clear drains if trained and protected. NRCA advises that people without roofing experience and equipment should not walk roofs, and OSHA fall protection rules apply near unprotected edges.
What is an infrared roof scan?
A survey after a sunny day, usually at dusk, that uses thermal imaging to spot wet insulation, which holds heat longer. Suspected areas are confirmed with cores.
Do I need an inspection before buying a commercial building?
It is wise. A roof replacement can be one of the largest capital costs on a building, and a report gives you a figure to negotiate with.
