A lot of hail days here don’t roll in like a gentle spring shower. It’s wind-driven, loud, and it hits one side of the house harder than the other. Then the sun pops out, the roof heats up, and by night you can be back near freezing. That hot-cold swing is when small cracks open up and a little bruise in a shingle turns into a leak path.
If you’re standing in your driveway in Centennial after a storm, you’re usually dealing with two things at once: figuring out if the roof actually took damage, and trying not to make it worse while you check. You don’t need to climb a steep pitch or start pulling shingles. You do need a clean, repeatable checklist so you can document what happened, spot the red flags, and know what to tell us when you call.
Start with safety and a ground-level walk, not the ladder
We see more injuries from post-storm “quick looks” than we ever want to. Hail leaves granules on walkways, and wind can loosen downspouts and power mast straps. Give it an hour if there’s lightning in the area, and wait until the roof surface is dry. If the storm dropped hail 1 inch or larger, assume the roof is slick, even if it looks fine.
Do a full lap around the house from the ground. Use a phone camera on 3x zoom and take slow video of each roof plane. Look for displaced shingles at the rakes and eaves, and check the corners where wind likes to lift the first few courses. If you’ve got a 6/12 pitch or steeper, keep your feet on the ground. You can still learn a lot.
Check the yard too. Downed branches can puncture a shingle mat, and a fresh dent in a metal window well cover tells you the hail had enough energy to do real roof damage.
Document the storm and capture photos that hold up later
Good documentation is boring, but it saves time. Put the date and approximate storm window in a note on your phone right away. Grab screenshots of the weather alert if you received one. If you have a hail report map from your area, save it, but do not rely on that alone.
For photos, we want context and detail. Take wide shots of each elevation so the roof planes are clearly tied to the home. Then take close-ups of anything you can safely access: gutters, downspouts, soft metals, and siding faces. A clean trick is to include a common object for scale, like a quarter or a tape measure, next to a dent.
If you see water inside, photograph it before you wipe it. A stain that’s 6 inches across today can spread to 24 inches after the next melt cycle. Note the room, ceiling location, and whether it is near a bathroom vent, chimney chase, or an exterior wall. Those details help us trace the path.
Check the gutters and soft metals first, they show hail impacts clearly
Asphalt shingles can take a hit and still look “fine” from the ground. Gutters and soft metals don’t hide it. Walk the perimeter and look at the gutter runs under the eaves. Aluminum K-style gutters will show round dents, often in a line where the hail came in at an angle. Downspouts can show flattened faces or fresh creases at elbows.
Now look up at the roof edges and penetrations. Drip edge (usually aluminum) can get a wavy, peened look. Counterflashing at chimneys, step flashing along sidewalls, and vent stacks can show dings and torn sealant. Rubber pipe boots are a big one. Hail can crack the neoprene collar around the pipe, and sun finishes the job after a few freeze-thaw cycles.
If you have skylights, check the frames and the surrounding flashing. We do not want you on the roof, but you can often see impact marks on the cladding and curb from a ladder placed safely at the eave line.
Know what hail damage looks like on the roof type you have
Centennial has a mix of roof systems. The signs are different, so your checklist should match what’s installed.
Asphalt shingles (architectural or 3-tab)
Look for random impact marks, not a neat pattern. Hail bruises can dislodge granules and compress the mat. From the ground, you might see dark spots, shiny areas where granules are missing, or tabs that look “scuffed.” Wind-driven hail often damages one slope more than the others, usually the west or north-facing plane depending on the storm track. If you’re thinking about upgrades after a storm, read hail-resistant shingles.
Concrete or clay tile
Tile can crack at corners or along the nose. A cracked tile might not leak today, but it can shift and break further with snow load. Look for fresh fragments in the gutters or at downspout outlets. Even a 1/4 inch chip at the edge matters because it changes water flow.
Metal roofing and metal accents
Standing seam panels will show dents, and fastener heads on exposed-fastener systems can loosen. Check ridge caps and valley metal for peppering. The failure mode here is often a compromised seam, a backed-out screw, or a torn washer. If you’ve got metal up there, this pairs well with how to check for metal roofing damage.
Inspect common leak entry points: valleys, flashing, vents, and chimneys
Most post-hail leaks are not “through the field” of the roof. They start where water is already concentrated. Valleys carry a lot of flow. If you have an open metal valley, hail can dent the valley metal and loosen the edge where shingles meet it. If it’s a closed-cut shingle valley, hail can fracture the shingle edges and open a cut line.
Vents are next. Bathroom exhaust vents, roof louvers, and attic intake vents can take direct hits. Plastic vent caps can shatter, and even a small break lets wind-driven rain push in. Check the attic if you can do it safely. Bring a flashlight. Look for wet decking around penetrations and darkened nail tips. If the roof decking is OSB, you’ll often see it swell at the edge when it has been wet more than once.
Chimneys are another repeat offender. Mortar joints can crack, and counterflashing can pull away. If you see a gap you can fit a pencil into where metal meets brick, that is a problem that usually shows up after the next heavy rain.
Inside the house: catch moisture early and stop it from spreading
If hail comes with wind, water can get pushed uphill and sideways. That means leaks can show up away from the obvious spots. Start with the attic if you have one, then work down.
In the attic, look at the underside of the roof deck around penetrations, valleys, and the top plates of exterior walls. Wet insulation is a giveaway. Fiberglass batts will slump and look matted. Cellulose will clump. If you see frost on the underside of the deck in winter, that can be an air leak and ventilation issue, but after a storm it can also be moisture intrusion that froze. If you want to go deeper on the attic side of it, this ties into roofing insulation.
Inside living spaces, check ceiling corners, around can lights, and near vent fans. Bubbling paint is late-stage. A faint brown ring is early. Take a photo and mark the spot with painter’s tape so you can find it again.
If water is actively dripping, put a bucket down and move valuables. Do not poke holes in drywall “to drain it” unless you know what’s above. We’ve opened ceilings where the water was traveling along a joist bay 6 feet from the stain.
Before you call us: protect the roof, avoid DIY damage, and get the right details ready
If you can see missing shingles from the ground or you have active leaking, the priority is temporary protection. The safest homeowner move is interior protection and attic catch pans. Exterior tarping on a steep roof is a fall hazard, and it is easy to do more damage by stepping on a bruised shingle or cracking a tile.
What you can do outside is keep water moving. Clear downspout outlets so gutters can drain. If a downspout is disconnected, set it back into the drop outlet and strap it if you can do it from a step ladder. Use 1-1/4 inch hex-head gutter screws if you have them, not drywall screws. Drywall screws snap.
When you call, have a few specifics ready. Roof age if you know it. Roof type and whether it is one layer or a tear-off was done last time. Any prior repairs in the last 2 years. Also tell us which slope got hit hardest and whether you saw hail size (pea, dime, quarter). That speeds up the inspection and helps us focus on the likely failure points for a hail damage roof in Centennial CO. If you want the longer version of the process, read how to handle hail damage, and if you’re trying to sort out symptoms that do not show up until later, this helps too: troubleshooting your roof from Centennial roofing contractors.
Key Takeaways
Wind-driven hail often damages one roof plane more than the others, document each slope separately.
Dents in aluminum gutters, drip edge, and flashing are often the clearest early proof of impact.
Rubber pipe boots and plastic vent caps fail by cracking, then leaking after the next freeze-thaw swing.
Valleys and chimney flashing are common leak starters, water concentrates there first.
In the attic, swollen OSB edges and dark nail tips are reliable signs of repeat moisture.
Skip steep-roof tarping as a homeowner, protect the interior and let our crews handle roof access.
Conclusion
After a hail day, the best move is slow and methodical. Stay off the roof, walk the perimeter, and collect clean photos of the stuff hail can’t hide on: gutters, downspouts, flashing, vent caps. Then check the attic and ceilings so you catch moisture before it spreads into insulation and drywall.
If you’ve got clear impact marks, missing material at the eaves, or any interior staining, it’s time to get eyes on it. We’ll inspect the full system, shingles or tile plus the soft metals and penetrations, because that’s where the leaks usually start. If you’re searching hail damage roof Centennial CO, call us with what you found and we’ll take it from there.
For weather alerts and storm timing, you can also cross-check your area using the local forecast and warning pages on the NOAA Weather Service site. For ladder and roof-edge safety basics, the OSHA page on fall protection rules and basic setup is a solid reference. If you’re comparing shingle types after a hail event, the UL 2218 impact resistance standard is what most manufacturers point to.
