A commercial flat roof in Winchester should be inspected at least twice a year — once in spring and once in fall — plus after any major storm, to catch problems while they’re still cheap to fix.
Why twice a year instead of once?
A fall inspection clears drains and finds summer heat damage before winter; a spring inspection catches whatever winter ice and snow load did before it becomes a leak.
Central Kentucky’s freeze-thaw cycle is hard on membrane seams and flashing in a way a single annual check tends to miss — damage that happened in January can sit unnoticed until a July storm finds the weak spot. Most manufacturer warranties on TPO, PVC, and EPDM systems also require documented periodic inspections to stay valid, so the twice-a-year cadence is as much about warranty protection as it is about catching leaks early.
What does a professional inspection actually check?
Membrane seams, flashing at every penetration, drains and scuppers, parapet coping, and any visible ponding — the same points that fail first and cause the most expensive emergency calls when they’re ignored.
Typical cost range
A standard inspection visit typically runs $150–$400 depending on roof size and access, and an infrared moisture scan adds to that if trapped moisture is suspected — labeled typical and confirmed with a written estimate before the visit.
Frequently asked questions
Does a roof inspection void my warranty if problems are found?
No — the opposite. Documented inspections are usually what a warranty requires; skipping them is more likely to void coverage than finding an issue during one.
Can I do the inspection myself?
A visual walk-through after a storm is fine, but the twice-yearly documented inspection should be done by a roofing contractor, since insurers and manufacturers generally want a professional’s written report, not a tenant’s note.
What happens if an inspection finds a problem?
You get a written scope and a price before anything is repaired — small issues found during a routine inspection are almost always cheaper to fix than the same issue found after it becomes a leak.
