A wind event should leave a record before it leaves a repair. Loose coping, a flapping membrane edge or a displaced exhaust hood each calls for a decision, and the decision depends on what was already wrong before the gusts arrived. In Yonkers, NY, we begin with a photo sequence from the access point outward: edges first, then the field, then the equipment. Each item gets a location, a condition and a plain statement of what is known and what is suspected.
The first practical question is hazard. Anything that could fall onto a street, a loading area or a pedestrian route is secured before the full inspection continues. The records come second, but they begin within the hour.
Wind leaves patterns. Edge metal pulled away at one corner and still tight at the others points to a local weakness. A row of loose fasteners suggests an attachment problem, and a lifted strip of adhered sheet suggests a bond that had already weakened. Debris marks and scrape lines show where something moved.
We separate observation from cause. A torn corner is an observation. Whether it tore because of the storm or because the sheet had hardened is a suspected cause until the material is tested. We photograph the torn edge, probe the surrounding membrane and note how the material behaves under the probe. Brittle sheet and supple sheet tell different stories.
Rooftop equipment gets its own entry. Hoods, vents, antennas and conduit supports can shift without visible damage to the unit, but the curb and flashing may be disturbed. Each unit is photographed from four sides, and its flashing is probed before the entry is closed.
Interior evidence is recorded too. Ceiling stains, wet tile, damp insulation visible through an access panel and water at a wall base each get a photograph with the room, the time and the weather. The interior location does not prove the roof entry point, so these entries sit beside the roof entries, not inside them.
Yonkers buildings share a constrained street and truck network. Getty Square's streets mix business activity with residential blocks, and trucks use the Nepperhan and Saw Mill valley to reach the Thruway. A lift or hoist on a narrow street needs a set time and a clear route.
We confirm the access window with the building contact: who opens the roof door, who escorts, which stairwell is used and which tenants are affected. A tenant on the top floor needs notice before a crew crosses their space. Where the roof is reached through a shared stair, the notice covers every tenant on the route.
Temporary protection is recorded as its own entry. Tarps, sealed patches and clamped edge metal are listed with the time installed and the area covered. They are not repairs, and the record keeps them separate from the permanent scope so the owner can see what is stopgap and what is final.
The repair boundary is the line between work and untouched roof. It has to land on material that will take a weld or a bond. We test the sheet beyond the visible tear, check fasteners in the next rows and, where moisture is suspected, scan the insulation. An infrared moisture survey narrows the wet area before any cutting starts.
Three scopes are common. A local repair resets or replaces edge metal, patches the tear and re-secures the fasteners. A section repair replaces a larger area where the sheet is weak. A larger project, such as a recover or replacement, applies when the existing assembly cannot hold a repair. The written scope names the choice and the evidence for it.
The state's updated codes took full effect on December 31, 2025. Local authorities answer zoning and construction questions, so the permit path is confirmed with the city for the scope and date. We list that check as an open item.
Cost drivers are listed with the scope. Edge metal length, number of damaged fastener rows, equipment that must be disconnected, lift time on a narrow street and the need for interior protection each change the price. Naming them lets the owner compare two proposals on the same terms.
Wind repairs depend on dry surfaces and workable temperatures. The regional station logs roughly 48 inches of precipitation a year and many freezing days, which limits when permanent repairs can be made. Cold, wet weather limits welding and adhesive cure, so permanent repairs are scheduled for a window that allows them.
Until then, the temporary measures need to hold. Tarps are fastened to the deck or curb rather than to loose membrane, and edge metal is clamped through sound substrate. We recheck them after the next wind event and log the check.
Each day's closeout lists what is open, what is covered and what waits for the next dry window. The log is brief and dated.
Winter wind events often arrive with freezing temperatures. The airport normals show nearly 105 days a year at or below 32 degrees, so cold-weather repair limits are part of the plan. A snow and ice event after a wind repair is checked against the same photo sequence.
The closeout file holds the photo sequence, the roof diagram with each repair located, the materials used, the temporary protection log and any open items. For owners with insurance questions, the file also separates storm-related items from pre-existing conditions, without deciding coverage. A storm damage repair record is easier for an adjuster to read when the sequence is clear.
Owners with several buildings can keep these records in a multi-site roof program. Properties in Bronxville or Mount Vernon can use the same format. If the same edge fails twice, the file shows it and the next decision is a stronger detail, such as the one used in flashing repair.
A short list of what to check after the next big wind helps owners who have no one on site. Look from the ground for edge metal that has shifted, any tarp or debris on the roof and fresh stains inside. Photograph anything unusual with the date and send it over, and we will compare it with the baseline in the file before anyone climbs.
After the repair, the open items list drives the next decision: a follow-up check after the next storm, a replacement of aged edge metal at the next project, or a larger scope if testing found brittle sheet. The owner gets a dated list, not a general recommendation.
That list is short on purpose. Each item names the condition, the location, who should act and by when.
The damage from the ground, the interior ceiling if water entered, and the access route. Add the date and time. Do not climb to take photos.
A temporary cover can go on at any time conditions are safe. A permanent weld or bond needs dry sheet and workable temperatures.
By pattern and material condition. Fresh tears and clean metal point to an event. Brittle sheet and old sealant point to age. We photograph both.
Sometimes only resetting is needed. If the substrate is damaged or the cleat is undersized, the edge is rebuilt.
That depends on scope and city rules. We list the permit check as an open item and confirm it before work starts.
