Commercial roof inspections, explained

How commercial roof inspections work

Know what you are buying before you buy it

Methods, checklists, credentials, reports and cost. Written so you can judge an inspection instead of taking one on trust.

What this site is for

A free inspection is a sales call

Someone has to pay for the time. If you are not paying, the report is the pitch.

The method decides what gets found

A walkthrough finds what is visible. Infrared and moisture scans find the wet insulation that a walkthrough cannot.

A report is only as good as its photographs

Findings without dated, located images are opinions you cannot act on or dispute.

No price listWhat an inspection costs turns on the building, the access and how much testing is included
Every sectionA roof is walked section by section, not judged from the corner nearest the hatch
Report firstThe inspector leaves and the document remains. Judge the visit by what it lets you do
Pick the methodA walk, a drone flight, an infrared scan and a core sample answer different questions
