Not every roof problem needs full replacement. When a Conway roof reaches the end of its serviceable life, continued repairs become a losing battle. You'll get an honest assessment of when replacement makes financial sense.
Conway is the Horry County seat, sitting inland along the Waccamaw River a short distance from Myrtle Beach, and Coastal Carolina University's campus on the edge of town has helped diversify what was historically a tobacco and timber economy tied to the river. The Waccamaw's blackwater swamp terrain surrounding the city means drainage and standing water are a real secondary concern after heavy rain events, on top of whatever direct roof damage a storm causes. Conway's inland position doesn't spare it from tropical weather: storms that make landfall along the Grand Strand near Myrtle Beach frequently track directly inland through Conway before losing significant strength, meaning the city absorbs real hurricane and tropical-storm wind and rain despite sitting several miles from the beach itself. The historic downtown along the riverfront carries older frame construction from Conway's tobacco-era growth, while newer residential development has spread out toward the university and along the routes connecting to Myrtle Beach, giving the city a genuine mix of older and newer roofing stock facing the same storm-track exposure.
When Replacement Makes Sense
Replacement typically becomes the right answer when the roof is approaching 20-25 years on standard 3-tab shingles, or 25-30 years on architectural shingles. It also makes sense when storm damage is widespread, granule loss is critical, or when underlayment and decking damage is extensive. Age alone rarely settles it — these are the factors that actually decide, and they matter together rather than any one on its own:
- Extent of damage, not just presence — a roof with isolated storm damage on one slope is usually a repair; the same damage spread across the whole roof surface tips toward replacement even on a younger roof.
- How many times it's already been repaired — a roof on its third or fourth repair in a few years is usually cheaper to replace than to keep patching, even if no single repair was expensive.
- What's underneath the shingles — if underlayment or decking has been compromised by long-term leaks, a repair only addresses the visible layer while the real problem continues underneath.
- Remaining shingle life relative to the repair cost — a repair on a roof with 15+ years of expected life left is a very different calculation than the same repair on a roof already past its rated lifespan.
What's Recommended for Conway Homes
For most Horry County homes, 30-year architectural dimensional shingles are the best value — they perform better than 3-tab in wind and impact resistance while lasting significantly longer.
