Hurricane Season Roof Readiness: A Checklist for Commercial Properties in the Southeast

Hurricane season runs from June 1 through November 30. If you manage commercial properties in Georgia, Florida, South Carolina, or along any Southeast coastline — that's six months of elevated risk for your building envelope.

The commercial roofing industry sees a predictable pattern every year: property owners who deferred spring maintenance discover, mid-August, that their roof has problems. Storm damage follows. Insurance claims are filed. Business interruption begins.

A structured pre-season inspection and maintenance program breaks this cycle.

Here is Seal Top's practical hurricane season readiness checklist for commercial properties in the Southeast.

Why Commercial Roofs Fail in Storms

Before the checklist, understand the failure modes:

Wind uplift at the perimeter. The most common point of storm failure is at the roof edge — parapets, copings, and perimeter membrane laps. Wind creates negative pressure (suction) at roof edges and corners that is 2–3 times greater than field wind pressure. Unsecured or aging termination bars and edge metal are the first failure points.

Penetration failures. HVAC units, skylights, pipe boots, and conduit penetrations are only as good as their flashing and sealants. Aged sealant cracks. Improperly installed counter-flashing lifts. Water entry at penetrations is the most common source of post-storm leak claims.

Drainage failures. Blocked drains create ponding during heavy rainfall events. The weight of standing water — 5.2 pounds per square foot, per inch of depth — can exceed the structural capacity of an older roof deck under sustained rainfall.

Membrane degradation. An aging membrane already experiencing micro-cracking or UV degradation is significantly more vulnerable to storm damage than a membrane in good condition.

The Pre-Season Checklist

1. Drainage System — Inspect and Clear

• [ ] Clear all primary roof drains of debris, vegetation, and sediment buildup
• [ ] Inspect and clear all secondary (emergency overflow) drains — confirm they are not capped or obstructed
• [ ] Check all scuppers: clear of debris, flashings intact, no separation from wall
• [ ] Inspect gutters and downspouts for damage, blockage, or improper slope
• [ ] Walk the roof after a moderate rainfall to confirm no ponding areas over 1/8" remain after 48 hours

*If you have persistent ponding areas, address drainage before storm season begins.*

2. Roof Edge and Perimeter — Critical Wind Uplift Zone

• [ ] Inspect all edge metal, coping caps, and gravel stops for lifting, loosening, or open joints
• [ ] Confirm termination bars at perimeter membrane laps are fully fastened — no gaps, corrosion, or loose sections
• [ ] Check parapet wall cap flashings for proper lap and securement
• [ ] Inspect roof-to-wall transition flashing at all parapet bases — confirm no separation or unsealed gaps
• [ ] Verify all counterflashing is properly seated and sealed

*Perimeter failure in high winds typically begins at unsecured edge metal. This is the single most important pre-season check.*

3. Penetrations — Every One, Every Seal

• [ ] Inspect all HVAC curbs: confirm counterflashing is intact, no gaps at base, no ponding around curb base
• [ ] Check all pipe boots, vent flashings, and conduit penetrations for cracked or missing sealant
• [ ] Inspect all skylights: confirm perimeter flashings are watertight, lenses are intact, no delamination
• [ ] Verify all exhaust fan flanges are sealed and properly secured
• [ ] Check any roof hatch gaskets for compression and seal integrity

4. Membrane Condition — Document and Repair

• [ ] Walk the entire roof surface and document (photograph) any blistering, splitting, or delaminated sections
• [ ] Identify and mark any open seams, fishmouths, or areas where lap adhesion has failed
• [ ] Check for any punctures from foot traffic, hail, or debris
• [ ] Note any areas of significant surface erosion or granule loss (modified bitumen)

*Any identified defects should be repaired before storm season — not after.*

5. HVAC and Rooftop Equipment

• [ ] Confirm all rooftop unit base frames are properly secured and flashed
• [ ] Inspect electrical conduit supports — loose conduit in high winds becomes projectile hazard
• [ ] Verify all pipe supports are properly anchored and not creating membrane stress
• [ ] Check that no equipment has shifted or vibrated loose since last inspection

6. Documentation and Insurance Readiness

• [ ] Confirm your current roof warranty is on file and accessible
• [ ] Photograph the entire roof surface in documented, systematic passes (or schedule drone documentation)
• [ ] Confirm your insurance carrier has current roof age, system type, and condition documentation
• [ ] Locate your roofer's emergency contact information — keep it with your emergency contacts
• [ ] Confirm your insurance policy's wind and named-storm deductibles

*Pre-storm aerial documentation significantly reduces disputes in post-storm insurance claims.*

After a Storm Event

If a significant storm impacts your property:

1. **Do not walk the roof** until safety has been confirmed (no structural damage, standing water, or electrical hazards)
2. **Call your roofing contractor immediately** for an emergency inspection
3. **Document from the ground** with photographs before any cleanup
4. **Contact your insurance carrier** to initiate a claim if damage is apparent
5. **Apply emergency tarping** only after a professional assessment — improper tarping can complicate insurance claims

Schedule Your Pre-Season Inspection

The best time to find a problem with your commercial roof is before the storm — not during it.

Seal Top Roof Management provides pre-season commercial roof assessments across the Southeast, including drone documentation and written inspection reports suitable for insurance and owner records.
