What does hail damage actually look like on asphalt shingles?
Hail leaves round marks where the granule surface has been knocked away or the shingle underneath has been bruised. The spots can be dark, shiny or soft to the touch. Cracks and dented soft metals nearby tell a roofer the stones landed hard enough to matter.
Asphalt shingle is a fiberglass mat coated with asphalt and topped with ceramic granules. A hailstone that lands hard enough knocks granules loose and can fracture the mat beneath, so the damage is a small, roundish area with no granules, sometimes with a soft spot under it. That soft spot is a bruise: the shingle is intact on top but weakened below.
Roofers also read the soft metals. Vent caps, drip edge and valley metal dent where a stone lands, and the pattern of dents tells the roofer which direction the storm came from and how heavy it was. A roof with clean metal and no marks on the shingles probably did not take a serious hit, even if the neighbor's did.
- Round, bare patches where granules are gone
- Soft, spongy spots when pressed
- Fresh cracks that cut through the shingle
- Dimples in vents, gutters and flashing
How can I tell hail marks from old age or algae?
Hail marks are round, scattered and fresh, with the mat showing through; age wear is spread evenly across a slope; algae is a dark streak on the surface that does not break the granule layer. A roofer can tell them apart in one pass.
This matters in Winston-Salem because the median home here was built in 1977, so a lot of roofs are on a second or third covering and are carrying years of normal wear. Granules shed slowly as shingles age, and humid Piedmont summers feed algae that darkens the surface in streaks. Neither of those is storm damage.
If you suspect hail, the best evidence is timing and pattern. Marks that appear on the storm-facing slope, matched by dents in soft metals, point to hail. Even wear across all slopes, or dark streaks below the ridge, usually do not. See roof moss and algae treatment if the streaks are what you are looking at.
Should I get the roof looked at after every hail storm?
Have it looked at when a warning named your area and cited hail, or when you see dented gutters, vents or siding. A roofer's inspection is the only way to learn whether the marks go through the shingle surface, and hidden bruising can show up later as leaks.
A warning that cites quarter-size hail does not mean your roof was hit, because hail falls in narrow swaths and one street can miss what the next street takes. It does mean a look is reasonable, particularly if you see any secondary sign such as dented gutters or a granule drift under a downspout.
Waiting has a cost when damage is real. A bruised shingle can let water in slowly, and the first sign is often a ceiling stain weeks later. For that stage, see roof leak repair. Ask the roofer to show you photos of what they find, so you can see the marks too.
What should I ask before signing for hail repair?
Ask what exactly was found and where, whether the repair is spot work or a full slope, who pulls the permit if one applies, and whether the quote is written down. Do not sign anything that hands an insurance claim to a contractor before you understand it.
Ask the roofer to explain the plan in plain terms and to show the marks. A roofer who tells you the whole roof is destroyed without showing you why deserves a second opinion. A roofer who finds a handful of damaged shingles and says so is giving you useful information even if the job is small.
Check the contractor's licence or registration with the issuing authority. North Carolina issues no roofing licence of its own, and general contractor licensing applies above the threshold set in state law, so confirm what the contractor holds and what the job requires.
