What are the signs your roof needs replacing rather than repairing?
Short answer. A roof needs replacing when problems are spread across the roof instead of in one spot: widespread granule loss, curling or cracked shingles on several slopes, soft or sagging decking, leaks in more than one place, or hail and wind damage on multiple slopes. A single missing shingle or one bad pipe boot is usually a repair.
Signs that point to replacement
- Wear on every slope: bald patches where granules are gone, shingles curling at the edges or cupping in the middle, and cracks across the tabs, especially on the south and west slopes that take the most Georgia sun.
- Brittle shingles: if shingles crack when a roofer lifts them to repair, a patch will not hold.
- Soft, spongy decking: it shows up underfoot or as sags between rafters seen from the street.
- Daylight or stains in the attic in several places: multiple leak paths mean the system is failing, not one part.
- Repeated repairs: two or three repairs in a few years on an older roof usually cost more than they save.
- Storm damage across slopes: hail bruises or creased shingles on several slopes are often a replacement claim, not a patch.
Signs that usually mean repair
- A few blown off shingles on an otherwise healthy roof.
- A cracked pipe boot or loose flashing at one chimney.
- One leak with an obvious source.
Age is context, not a verdict
Architectural shingles in Georgia commonly last about 20 to 30 years, and 3-tab roofs less. A 12 year old roof with hail damage may need replacing sooner; a 22 year old roof in good shape may have years left. Get the roof looked at up close rather than judging from the ground.
