After-Hail Garage Door Inspection Checklist (Denver)

Why This Checklist Matters

Most Denver-metro homeowners look at their garage door after a hailstorm, see the obvious panel dents, and stop. That misses 40–60% of the actual damage. Hail affects tracks, springs, cables, the opener housing, the bottom seal, the windows, and the weatherstripping — not just the visible panels. We've had calls 6 months after a storm where the homeowner discovered the bottom seal had been hail-cut and was leaking snowmelt into the garage all winter. Doing a proper inspection within 48 hours catches the hidden damage while it's still cheap to fix.

After a Denver-area hailstorm, work through these 12 inspection points: panels (1–5), tracks (6), springs (7), cables (8), opener housing (9), bottom seal (10), windows (11), and weatherstripping (12). Document everything in raking light. Don't operate the door until inspection 1–6 is complete. Call OnPoint Garage Denver at (303) 732-8236 for a free verification.

The 12-Point Checklist (Step by Step)

Point 1: Panel Surface Damage (Outside)

Walk to about 15′ from the closed door. In raking morning or evening sun, scan each panel left to right. Look for: dimples, dents, paint cracks, and any "starring" patterns. Photograph each panel from this distance. Then walk closer — within 3′ — and re-photograph any damage with a coin or finger for scale.

Point 2: Panel Damage Counting

Count visible dents per panel. Note: light dimpling (under 0.25″ depth), medium dents (0.25″–0.5″), and severe dents (over 0.5″ or deformed). The proportion of medium-to-severe dents drives the repair-vs-replace decision.

Point 3: Panel Damage Inside

Open the door from inside (manually if you suspect track damage — see point 6 first). Look at the back of each panel. Some hail impacts are visible only from inside because the foam compresses but the outer skin doesn't. Insulated doors particularly show inside-only deformation.

Point 4: Panel Joints and Seals

Check where panels meet each other. Hail can deform the top edge of a lower panel enough to break the panel-to-panel seal. Look for daylight or shadow lines that weren't there before.

Point 5: Panel Ribs and Reinforcement

Many doors have horizontal struts on the back of each panel for wind reinforcement. Check that struts are still straight and bolted tight. A bowed strut means the panel took a hit hard enough to flex the entire section.

Point 6: Tracks (Critical Before First Operation)

Look at the vertical tracks and horizontal tracks above the door. Run your eye down the inside surface where rollers contact — any dents, bulges, or deformations? Hail rarely hits tracks directly, but if a roof line failed and dumped hail across the track curve, you can get track damage. Do not operate the door until tracks are confirmed clear.

Safety Warning — Track Inspection First A dented track will bind the rollers and force the opener to over-torque. Best case: opener gears strip. Worst case: cables jump off drums, panel flies sideways, someone gets hurt. Always inspect tracks before opening the door for the first time after a major storm.

Point 7: Torsion Springs

Spring damage from hail directly is rare (springs are protected above the door), but spring DAMAGE FROM EXTRA STRESS is common. If hail bent a panel or strut, the springs now have to lift an unbalanced load. Look for: spring gap (a visible gap in the coil = broken spring), unusual rust streaks under the spring, or daylight between coils that wasn't there before.

Point 8: Cables

The cables run from the bottom corners up to the drums above the door. Inspect both cables: are they still seated in the drum grooves? Any fraying, kinking, or looseness? A bent panel can pull a cable off-track even if the cable itself is fine.

Point 9: Opener Housing

The opener motor housing (mounted on the ceiling) is exposed if your garage has a window above the door or a translucent roof panel. Most hail damage to openers is cosmetic, but check: housing dents, broken light covers, cracked drive case, any visible damage to the chain or belt cover.

Point 10: Bottom Seal (Often Overlooked)

The bottom rubber or vinyl seal is the most-missed hail-damage item. Direct hail impact, rebounding hail from the driveway, or panel deformation can cut, tear, or unseat the seal. With the door closed, look along the bottom from inside — any daylight visible? Daylight = water + cold air will enter all winter.

Point 11: Windows (If Equipped)

Acrylic or polycarbonate window inserts crack at smaller hail sizes than steel dents. Look for: cracks (radiating or starring), full-pane breaks, broken seal between the window and the panel frame. We cover window-specific repair in a dedicated article.

Point 12: Weatherstripping (Sides and Top)

The vertical and top weatherstripping is rubber or vinyl. Hail-driven debris or impact can cut, tear, or detach it. Check the entire perimeter for gaps, tears, or sections that have pulled away from the jamb.

Pro Tip — Document Everything Take 30–50 photos. Date-stamped (camera default). Include wide shots, close-ups with scale, and shots of every damaged point. This documentation is valuable for any insurance discussion and for getting accurate repair quotes from contractors.

What to Do After the Checklist

Tally damage by category. Panels, tracks, springs/cables, opener, seal, windows, weatherstripping.
Decide urgency. Operability issues = same-day. Bottom seal leak = within 2 weeks (before next snow). Cosmetic panel dents = within 30 days.

Keep your photos and notes for any insurance discussion.

Common Mistakes Denver Homeowners Make

Mistake	What Goes Wrong
Operating door before track check	Opener strain, possible cable jump, gear damage
Skipping the bottom seal	Winter water intrusion, garage flooding
Ignoring window cracks	Cracks propagate over freeze-thaw cycles
Photographing only outside	Miss insulated-panel inside-only damage
Waiting more than 30 days	Paint cracks rust pinholes, weatherstrip degrades

Pro Tip — Inspection in Bad Light If you can't inspect in raking sun, use a flashlight held parallel to the panel surface (almost touching). The grazing-angle light reveals dents invisible under overhead light. This trick alone catches 80% of light dimpling that homeowners miss.

Opener strain noises (grinding, slipping) you didn't hear before
Bottom seal cut or unseated

Frequently Asked Questions

How soon after a hailstorm should I inspect my garage door?

Within 48 hours of the storm. Same-day if you saw 1-inch+ hail. Earlier inspection catches damage while paint is still fresh and seals haven't shifted, which makes repairs cheaper and faster.

Can I do the garage door hail inspection myself?

Yes - the visual inspection points (panels, tracks, seal, windows, weatherstripping) are safe DIY. Do not test springs, cables, or opener under load yourself. If anything in points 6-9 looks wrong, stop and call a professional before operating the door.

What if my door operates normally - do I still need inspection?

Yes. Bottom seal cuts, paint cracks, and partial-panel damage often don't affect operation but cause expensive problems later (winter water intrusion, rust pinholes, paint failure spreading).

How long does a professional hail inspection take?

20-40 minutes on-site for a single double-car door. We provide a written assessment with photos and repair options before leaving. No service-call fee for hail-season assessments.

What does grazing-angle light reveal that overhead light doesn't?

Light dimpling, shallow dents, and surface deformations that are invisible under overhead sun. Holding a flashlight almost parallel to the panel surface casts shadow lines that show every dent - the technique professional storm-damage inspectors typically use.

Should I open the garage door before inspection?

No - finish points 1-6 first. Track damage can cause cable jumps or opener strain if you operate before checking. After the visual track inspection is complete and looks clean, you can carefully open the door manually first, then with the opener.

Do you charge for on-site hail inspections?

No. On-site hail inspections across the Denver Front Range are free. We provide a written assessment and quote with no service-call fee.
