Wind and Storm Damage Roof Insurance Claims.

Roof Scope Notes

A lot of commercial roof wind damage in the Lowcountry has nothing to do with a named storm. Tropical storms and depressions that never strengthen past hurricane threshold still bring sustained wind through the metro most years. Coastal lows can stall off the Southeast coast for days, producing the kind of persistent onshore wind more associated with a nor'easter than a tropical system. Spring and summer bring their own pattern: fast-building thunderstorms with straight-line wind and occasional small hail.

Each of these produces a different damage signature. A sustained coastal-low event tends to show gradual creep - a seam separated a few inches at a time, ballast migrated toward the leeward parapet. A severe thunderstorm event is usually the most localized and obvious - a section of membrane peeled back, a rooftop unit's fins bent in one direction.

What all three have in common is that the damage can be real and claimable without a hurricane deductible or a declared named storm. Standard wind and hail coverage typically applies - a different set of policy terms than named-storm provisions. We are not the ones who interpret which provision applies, but our documentation records the date, the type of weather event based on available public weather reporting, and the specific physical damage.

We check edge metal and coping first, since that is where uplift typically initiates, then move to field seams, rooftop equipment curbs, and penetrations that could have taken wind-driven debris impact.

Drainage is worth separating out on its own for peninsula and low-lying buildings near the Ashley and Cooper rivers - a multi-day coastal low combined with an unusually high tide can back up drains even without hurricane-force wind.

No. Straight-line wind from a severe thunderstorm, a tropical storm that never reaches hurricane strength, or a coastal nor'easter-style low can all produce roof damage under standard wind coverage rather than named-storm terms.

Coastal low-pressure systems can stall off the Southeast coast and produce days of sustained onshore wind and heavy rain without ever being named or reaching tropical strength.
