Most commercial roofs fail slowly, then all at once. Small problems hide under the membrane until water reaches the insulation, the deck, or your tenants. A steady inspection schedule catches them while they're still cheap.
Two are on the calendar. Two are triggered by what happens to the building.
Freeze-thaw cycles, ice, snow load, and ponding water open seams and crack flashing. Find it before spring storms push water through.
Summer heat and UV dry out membranes and sealants. Clear drains and fix weak spots while the weather still allows repairs.
Hail, high wind, tornadoes, and hurricanes. Damage on a flat roof is often invisible from the ground and easy to miss from the roof.
HVAC, electrical, solar, and telecom crews drop tools, leave screws, and puncture membranes. Check after anyone works up there.
Put these on the facility calendar and keep every report on file. A dated history of your roof is worth as much as the inspections themselves.
| When | Why | What to focus on |
|---|---|---|
| Spring | Winter damage, before storm season | Seams, flashing, ponding areas, drains and scuppers, ice damage at edges and penetrations |
| Fall | Summer wear, before winter | UV and heat aging, sealant and caulk, debris in drains and gutters, rooftop equipment curbs |
| After a storm | Hail, wind, tornado, hurricane | Hail fractures and dents, lifted edges and coping, displaced equipment, punctures from debris |
| After rooftop work | Other trades on the roof | Punctures, dropped fasteners, open access panels, damaged walk pads |
| Any leak | Water inside means it's already through | Source of the leak, wet insulation, and how far water has spread under the membrane |
Every inspection should be documented with dated photos and written notes covering all sections of the roof. That record is what warranty holders, insurers, and buyers ask for.
Most commercial roof warranties require annual or twice-yearly professional inspections and documented maintenance. Without the records, a manufacturer can deny a warranty claim, and the warranty becomes paper.
Multi-ply built-up roofs typically last 20–30 years and single-ply (TPO, EPDM, PVC) roofs 15–25 years. Neglected roofs fall short of those numbers. Maintained roofs reach them.
On a flat roof, a small opening lets water spread under the membrane and soak the insulation long before a ceiling stain shows up. By then the repair is bigger, and sometimes it's a tear-off.
An inspection right after a storm gives you dated photos and findings tied to that event. A baseline report from before the storm makes the comparison even clearer. Insurance policies have time limits for reporting damage, so check yours.
A hailstone can fracture the membrane or crush the insulation underneath and leave almost nothing to see on the surface.
On low-slope roofs, hail can crack single-ply membranes, knock granules off modified bitumen, dent metal, and crush the cover board below. Those strikes often show up months later as leaks, long after the storm.
That's why a storm inspection on a commercial roof needs a trained inspector who knows what hail damage looks like on each roof type, and who checks the whole system, not just the spot that's leaking. Skylights, smoke vents, and rooftop equipment should be checked too.
If there's no damage, you get that in writing as well. We'll provide a Clearance Certificate you can keep on file.
A real commercial roof inspection looks at three areas: inside the building, the perimeter, and the roof surface.
When there's a question about trapped moisture, infrared (thermal) scanning and core samples show what's happening inside the roof system without guessing.
SkyView is a team of roofing experts with 25+ years of hands-on experience in commercial roofing, storm damage, and restoration. We're certified installers with nearly every major flat-roof manufacturer, so we know how each system is built and how each one fails.
For a newer roof with little rooftop traffic, an annual inspection plus storm checks may be enough. Most of the industry recommends twice a year because the spring and fall inspections catch different problems: winter damage in spring, heat and UV wear in fall.
Staff walk-throughs are a good habit, especially for clearing drains and spotting obvious damage. But warranty inspections and storm inspections should be done by a trained roofing professional who knows how each membrane fails and can document it properly.
Yes. Installation defects, trade damage during other construction, and storm damage can all happen in the first few years. Early inspections also start the maintenance record your warranty depends on.
It depends on the size of the roof and how much equipment is on it. Most are done in a few hours on site, with a written photo report to follow. Using a drone, we can often inspect without disrupting your tenants.
We document it with photos and a written report, show you exactly what we found, and explain your repair or replacement options. If you choose to file a claim, the report gives you clear evidence to share with anyone who asks.
Then you'll know your roof is sound, and we'll give you a Clearance Certificate to keep on file. It's a dated record of your roof's condition that helps with future storms, warranty questions, and property sales.
