How Do Pros Assess Wind Damage on a Multi-Story Building?
Last updated October 26, 2026
The short answer
Start with the Exterior
The first step is a thorough look at the building's outside. Pros walk the perimeter, checking for visible signs like torn siding, cracked stucco, or popped nails. They pay attention to corners and edges, where wind pressure is strongest. Using binoculars or a drone, they examine upper floors and the roofline without needing a ladder.
They also check windows and doors for gaps or broken seals. Wind can push rain into tiny openings, causing hidden water damage. Pros note any debris, like branches or loose shingles, that might have struck the building. This initial scan helps them decide where to focus a closer inspection.
- Inspect roof edges and flashing
- Look for missing or lifted shingles
- Check windows and door seals
- Note any impact marks from debris
- Examine soffits and fascia boards
- Look for bent gutters or downspouts
Check the Roof Structure
The roof takes the brunt of high winds. Pros look for lifted or missing shingles, damaged flashing around vents and chimneys, and any signs of membrane peeling. On flat roofs, they check for ponding water or bubbles in the membrane, which can indicate wind-driven uplift. They also inspect the roof deck for soft spots.
If the roof has a parapet, they check its coping for looseness. Wind can get under loose edges and tear large sections away. Pros may use a moisture meter to detect hidden leaks under the roofing material. This helps them understand whether the damage is just cosmetic or if water has already entered the building.
Look at Walls and Openings
Walls on multi-story buildings often show wind damage as cracks or bulges. Pros tap on siding and stucco to find hollow areas, which suggest the sheathing behind has pulled away. They also inspect around windows and doors, where pressure differences can cause frames to shift. Caulking and weatherstripping get a close look for tears.
On upper floors, pros look for bowed walls or separated joints. They may check the alignment of window sashes and doors to see if the frame is still square. If the building has balconies, they examine the railings and floor-to-wall connections. These areas are vulnerable to wind uplift and can pose a safety risk if damaged.
Evaluate the Interior
Inside the building, pros look for signs that wind-driven rain entered. Water stains on ceilings or walls often appear near windows, skylights, or roof penetrations. They feel for dampness in carpets and drywall, and use moisture meters to trace the extent of wet areas. A musty smell can also signal hidden dampness.
They check for drafts around windows and doors, which can indicate air leaks. Pros also look for cracks in interior walls, especially near corners, that might suggest structural movement. If the building has an elevator shaft or stairwell, they inspect those areas for water entry. The interior assessment helps them determine if repairs are needed beyond the exterior.
Document Everything for Insurance
A detailed record of the damage is essential. Pros take photos from multiple angles, including close-ups of specific issues and wide shots that show the overall condition. They note the date and time of the inspection, and they may use a measuring tape to record the size of cracks or missing areas. This documentation helps you file a claim.
Policies vary, and your insurer decides what is covered. Keep all records, including any reports from the pros, in a safe place. If you live in St. Petersburg, having a clear record is especially useful, given the humid subtropical climate. A thorough assessment helps you understand the scope of repairs and supports your insurance discussions.

How long does a wind damage assessment take?
The time depends on the size and height of the building. A simple walk-around might take an hour, while a detailed inspection of a large multi-story building could take several hours. Pros often need to access the roof and upper floors, which adds time. The key is thoroughness, not speed.
Can I do the assessment myself?
You can spot obvious issues like missing shingles or broken windows, but a professional assessment is safer and more thorough. Pros have the training and equipment to reach high areas and detect hidden damage. They also know what to look for in terms of structural integrity. For a multi-story building, it's sensible to rely on a pro.
What if I find damage after the pros leave?
If you notice new issues later, contact the pros again. Sometimes damage is not visible until after a rain or when the building shifts. Document any new findings with photos and notes. The original assessment can be updated, and you should share the new information with your insurance company. Acting quickly helps prevent further problems.
