What should be checked first after a storm?
After a storm, begin with safety and a ground-level inspection. Do not climb onto the roof while surfaces are wet, icy, covered with debris, or visibly unstable. Many roof problems can be identified from the yard, attic, ceilings, and upper floors without stepping onto the roof.
Storm damage may be obvious, such as missing shingles or a fallen tree limb. It can also be subtle. Wind may loosen roofing materials without removing them, while hail can leave small impact marks that become leak points later.
Before inspecting, wait until:
- Lightning and strong wind have passed
- Downed wires and electrical hazards are cleared
- The ground is stable enough to walk safely
- Rain or snow has stopped, if possible
In Rochester, NY, storm inspections may be needed after thunderstorms, high-wind events, heavy rain, hail, lake-effect snow, ice buildup, or rapid freeze-and-thaw cycles. Seasonal weather can also leave branches and other debris on roofs that are not easy to see from inside the home.
How can a roof be inspected safely from the ground?
Walk around the property and look up at the roofline from several angles. Use binoculars if available rather than climbing a ladder.
Look for:
- Missing, lifted, curled, cracked, or displaced shingles
- Dark or exposed areas where the roof covering appears absent
- Loose flashing around chimneys, vents, skylights, and roof edges
- Bent or detached gutters and downspouts
- Fallen branches, broken limbs, or other debris
- Granules collecting heavily near downspout outlets
- Sagging sections along the roofline
- Exposed underlayment, wood, or fasteners
- Damaged soffits, fascia, siding, or exterior vents
A roof does not need to look dramatically different to have sustained damage. A shingle that is lifted at one edge may allow water underneath during the next rain. Wind can also loosen ridge caps or edge materials while leaving the main roof surface appearing intact.
Check the ground for pieces that may have blown from the roof. Shingle fragments, metal flashing, plastic vent parts, or large amounts of granules can help identify damage even when the roof itself is difficult to view.
What should be checked inside the house?
The attic and upper ceilings often reveal water entry before a roof leak becomes visible in a living area. Inspect the attic only if it can be reached safely and there is adequate lighting.
Look for:
- Damp or discolored roof sheathing
- Wet insulation
- Water stains around vents, chimneys, and skylights
- Drips, puddles, or a musty odor
- Darkened wood or signs of prolonged moisture
- Daylight visible through the roof deck
- Compressed or shifted insulation
Inside the living space, check ceilings, upper-floor walls, closets, and areas near exterior walls. Fresh stains may appear tan, brown, or yellow, but water can travel along framing before becoming visible. A stain that is not directly below the roof damage does not rule out a roof leak.
If water is actively entering, place a container under the drip and move furniture or electronics away from the area. Do not touch wet electrical fixtures, outlets, or wiring. If a ceiling is bulging, avoid standing beneath it because trapped water can cause part of the ceiling to fall.
How can wind damage be distinguished from normal roof aging?
Storm damage is usually associated with a specific weather event, while ordinary aging tends to develop gradually across larger areas. The difference is not always obvious, but several clues can help.
Wind-related damage often includes isolated shingles that are lifted, creased, torn, or missing. Damage may be concentrated along ridges, roof edges, corners, and sections exposed to prevailing winds. Nearby homes or outbuildings may show similar effects after the same storm.
Normal aging may include widespread granule loss, brittle shingles, surface cracking, faded color, or curling across much of the roof. Older materials can still be affected by a storm, but a pre-existing condition may make it harder to determine exactly when a problem began.
Hail damage can appear as small circular dents, bruised areas, or missing granules. These marks may be difficult to see from the ground and can resemble ordinary wear. Do not press on suspected impact marks or scrape the surface, since that can worsen the damage.
What about gutters, flashing, and roof drainage?
Storm inspections should include the drainage system because roof water damage is not limited to shingles. Gutters that pull away from the fascia can allow water to run down walls or collect near the foundation.
Check whether:
- Gutters are still firmly attached
- Downspouts remain connected and direct water away from the foundation
- Elbows or extensions have separated
- Gutter sections are dented, twisted, or blocked
- Water is overflowing from unusual locations
- Flashing is missing or visibly lifted
- Roof valleys contain leaves, branches, or damaged materials
A small amount of debris is common after a storm, but large branches or compacted leaves can obstruct drainage. Never walk on a roof to clear debris if the surface is steep, wet, damaged, or unstable. A roof that appears sound may still have weakened decking underneath.
Should storm damage be documented?
Yes. Photographs and written notes can help establish what was found and when it was observed. Take wide photos showing the roof in relation to the house, followed by closer images of visible damage from a safe location.
Record:
- The date and approximate time of the inspection
- The type of storm or weather conditions
- The location of each visible problem
- Any interior stains, dampness, or active leaking
- Debris found on the roof or ground
- Temporary steps taken to reduce additional water entry
If there is a risk of further damage, use only safe temporary measures. A tarp should not be installed by someone without the proper equipment and experience, especially on a steep or slippery roof. Avoid nailing materials into a damaged roof unless emergency conditions and safety requirements clearly support that action.
When does roof damage require immediate attention?
Immediate attention is warranted when the roof is visibly sagging, a large section is missing, water is entering rapidly, a tree has struck the structure, or electrical hazards are present. A damaged chimney, skylight, vent, or roof edge can also allow water to enter quickly.
Leave the affected area if there is a structural concern, strong odor of gas, exposed wiring, or a ceiling that is bulging significantly. Storm debris may conceal broken glass, nails, unstable branches, or damaged utility lines.
Minor-looking damage should not automatically be ignored. A lifted shingle, loose flashing section, or small ceiling stain can allow repeated moisture entry. In a climate with wet weather, snow, ice, and freeze-thaw conditions, water that enters beneath roofing materials can expand as it freezes and make the original problem worse.
What should not be assumed after a storm?
A roof does not have to leak immediately to be damaged. Some openings remain dry until wind-driven rain reaches them from a particular direction. Likewise, the absence of visible debris does not prove that all roofing materials are secure.
It is also a mistake to assume that damage is limited to the roof covering. Storm conditions can affect flashing, vents, gutters, insulation, siding, attic ventilation components, and interior finishes.
A careful inspection begins from the ground, continues inside the attic and upper floors when safe, and focuses on documenting conditions without creating additional hazards.
