15 Signs Your Woodbury Roof Took Storm Damage (Even If It Looks Fine)

Most Woodbury homeowners don’t know if their roof took damage on September 21 because hail damage on asphalt shingles is sneaky. It usually doesn’t leak right away. It looks “fine” from the ground. The damage is happening at the granule and mat level, where you can’t see it without getting on the roof — or knowing exactly what to look for from down below.

Here are 15 signs you can check yourself, in roughly the order we use during a free Owl inspection. Most can be checked from the ground with a phone and 15 minutes. If you find two or more, schedule a real inspection.

The 15-sign checklist

Signs you can spot from the ground

1. Dented gutters. Top edges of aluminum gutters dent easily. Walk every run with your phone and zoom in. Dents = a hail event happened.
2. Pocked downspouts. Same logic — soft aluminum tells the story.
3. Granules at gutter outlets. Pull the elbow at the base of a downspout. A handful of asphalt granules pooling there after a storm is a strong signal of recent shingle impact.
4. Dented AC condenser fins. The aluminum fins on your outdoor AC unit are a soft-metal witness. Dented fins after Sept 21 = hail event for your property.
5. Damaged screens or torn vinyl on the downwind elevation. If hail came at an angle, your downwind side took it. Look at every screen and section of vinyl.
6. Cracked or fogged window panes. Hail strong enough to damage roofing is often strong enough to crack glass.
7. Damaged exterior paint or trim. Wood trim shows hail strikes as round chips or knockdowns.
8. Roof shingle pieces in the yard. If you found shingle granules or torn shingle pieces in your lawn after Sept 21, that’s a clear sign.
9. Visible bruising on the roof from a safe ground angle with zoom. On low-pitch roofs you can sometimes see dark dots distributed across the slope. Each is a potential hail bruise.

Signs that show up in the attic or interior

10. Daylight visible through roof decking. Go to the attic during the day. Lights off. Any visible daylight is a problem.
11. Water stains on rafters or decking. New water staining since Sept 21 means hail damaged the roof’s water shedding.
12. Stains on ceilings of upper floor. Yellowish or brown ring stains, especially in corners or near the chimney, indicate water intrusion.
13. Sagging or soft spots when walking the upper floor. Sustained leaks weaken decking and structural elements over time.

Signs you’ll need a professional to confirm

14. Test square impact counts. A licensed roofer marks a 10′ x 10′ square and counts hail bruises. Most insurance carriers consider 8+ hits per square strong enough to support full replacement, though specifics vary.
15. Soft, spongy spots when pressed on shingles. Fractured mat under the granule layer. This is the definitive hail damage signal — only confirmable by walking the roof.

Comparing what you can spot vs what we can spot

From the ground, you can answer ‘did hail hit my house.’ From the roof, we can answer ‘how much.’

Common Woodbury Sept 21 damage patterns we’re seeing

• Northwest-facing slopes hit hardest. Storm direction during the Sept 21 cells was generally west-to-east with northwest wind exposure.
• Downwind elevations of houses (south/southeast siding). Sideways hail from wind angle.
• AC condenser denting nearly universal in hardest-hit blocks. Even homes where roofs were “borderline” claims had clearly damaged AC units.
• Gutter denting on multiple runs. Sept 21 hail came at varying angles in some neighborhoods, so gutters on multiple sides got hit.
• Skylights cracked on direct-overhead pitches. Less common but happening in some Woodbury homes.

What to do once you’ve checked

0-1 signs. You’re probably fine, but a free inspection costs nothing and removes doubt before the September 21, 2026 bar. Schedule one anyway.

2-4 signs. You probably have damage. Schedule the inspection and start documenting everything. Don’t file the claim yet — get the contractor report first.

5+ signs. You almost certainly have a claim. Get the contractor inspection ASAP, then file your insurance claim with the contractor’s report attached.

Things people think are hail damage but aren’t

• Algae streaks. Black streaks on shingles are usually algae (Gloeocapsa magma), not hail damage.
• Granule loss at field edges. Some natural granule loss from edges of shingle tabs is normal aging.
• Curling or cupping shingles. Age and ventilation problems, not hail.
• Missing tabs from wind events. That’s wind damage (covered), not hail.
• Tree branch damage. Linear scratches and broken shingles from impact, not the round bruise pattern of hail.

Documentation tips for what you find

1. Photo every sign with date stamp visible (most phones embed this in metadata)
2. Save a copy in two places (cloud + local)
3. Note the date you took the photo and what room/elevation it shows
4. Don’t repair anything yet — wait for the contractor and adjuster inspections first
5. If something is leaking actively, tarp it (or call us for emergency tarping) to prevent further damage
