Decatur homes built before 1970 in Millikin Heights and the Near Westside often carry three-tab shingles that crack under hail rather than dent. After a typical June or July storm rolling off Lake Decatur, crews see granule loss and cracked seals along the north-facing slopes where wind-driven hail concentrates. Replacing only the damaged courses instead of the full roof keeps the job inside Macon County permitting rules while matching the existing 25-year shingle life left on many East End properties.
Metal roofs on commercial buildings near the Decatur Civic Center and along the lakefront take different damage—dents that later collect water and start rust at the seams. Local crews carry portable dent-pull kits and seam sealant rated for the freeze-thaw cycles common between Forsyth and Mount Zion. Skipping the sealant step leads to leaks the following winter when temperatures drop below freezing for weeks.
Insurance adjusters in Macon County require photos taken within 48 hours of the storm because hail craters fill with dirt quickly. Documenting the exact size and spacing of hits on both the roof and nearby siding prevents later disputes. Homeowners in Downtown Decatur sometimes overlook skylight damage that shows up only after the next heavy rain.
Edge flashing and step flashing around chimneys in older two-story homes near Millikin University campus are frequent failure points after hail. These areas sit at different angles and collect more direct hits. Replacing just the flashing and resealing the step joints often restores the roof without touching the main field.
Technician insight
In Decatur the thing that catches most people out with hail damage roof repair is how brittle the old three-tab shingles become after twenty winters; once they crack they shed granules fast and the underlayment starts to rot before the next spring thaw. Homes in the East End and Millikin Heights sit on slightly higher ground so wind-driven hail from Lake Decatur storms hits the north slopes harder than anything you see in newer Forsyth subdivisions.
East End two-story after July hail
Hail cracked three-tab shingles on the north slope of a 1962 home near Lake Decatur. We found hidden leaks at the chimney flashing during the attic check. Replaced two damaged courses and resealed the step flashing. No further leaks reported after the next heavy rain.
