10 Best Roof Replacement Companies in Myrtle Beach SC [2026 Rankings]

The 25% rule is an industry guideline for deciding between repair and full replacement. If more than 25% of your roof's surface is damaged — missing shingles, active leaks, structural sagging, widespread granule loss — most contractors recommend a full replacement instead of patching. Below 25%, repair is usually cost-effective. Above 25%, the patch-and-repeat cycle costs more over 3-5 years than one replacement.

Based on 72 completed projects tracked by Homeyou in April 2026, the typical Myrtle Beach roof replacement runs $6,273-$7,058 for a standard residential project, with the full range landing between $5,880 and $7,450. Larger homes and premium materials move higher — a 2,000 sq ft asphalt replacement averages ~$12,608 in South Carolina, while a 2,000 sq ft metal replacement averages ~$36,878 per IndigoStateRoofing 2026 data. Your exact quote depends on roof size, material, pitch, and deck condition.

Winter (January-February) is typically the cheapest window to schedule a roof replacement on the Grand Strand. Fewer homeowners book replacements during cold months, so contractor pricing becomes more competitive and scheduling is faster. The tradeoff: weather delays are more likely, and some shingle manufacturers require minimum installation temperatures. Late winter into early spring (February-March) is often the sweet spot — pricing still soft, weather more workable.

According to IndigoStateRoofing's 2026 cost data, South Carolina roof replacement averages by roof size: 1,000 sq ft — ~$6,300 asphalt / ~$18,439 metal. 1,500 sq ft — ~$9,456 asphalt / ~$27,659 metal. 2,000 sq ft — ~$12,608 asphalt / ~$36,878 metal. 2,500 sq ft — ~$15,759 asphalt / ~$46,098 metal. Myrtle Beach coastal homes often need upgraded wind-rated shingles and stainless-steel fasteners, which can add 10-15% to the baseline estimate.

Most Myrtle Beach residential replacements are completed in 1-3 days. A 2,000 sq ft asphalt replacement typically takes 1-2 days in good weather. Larger homes, steep pitches, or deck-repair work can extend to 4-5 days. Metal replacements take longer — 3-5 days for residential. Hurricane season (June-October) introduces weather delays, so scheduling in April-May or November-December usually yields the fastest completion.

South Carolina homeowners insurance typically covers replacements caused by sudden storm events — hurricanes, hail, fallen trees, wind damage, fire. It does NOT cover age-related wear, lack of maintenance, or gradual deterioration. Coastal policies (Horry County, Georgetown County) often carry a separate hurricane/named-storm deductible (typically 2-5% of dwelling coverage) that applies before standard coverage kicks in. Get a storm-damage inspection within 7-14 days of a named storm to preserve claim eligibility.

For Myrtle Beach's hurricane-exposed coastal climate: impact-resistant architectural asphalt shingles (Class 3 or 4 hail rating, 130+ mph wind rating) are the baseline. Metal roofing is excellent for salt-air durability and delivers 40-70 year lifespan with up to 140 mph wind resistance — but costs 2.5-3x more upfront. Tile performs well coastally but requires structural reinforcement on most SC homes. GAF Timberline HDZ LayerLock with ArmorShield II is the most-installed premium shingle on the Grand Strand for its 130-mph wind rating and Golden Pledge® warranty tier.

Verify: (1) active South Carolina LLR contractor license; (2) general liability + workers comp insurance (ask for certificates); (3) manufacturer certification (GAF Certified, GAF Certified Plus™, or GAF Master Elite); (4) BBB accreditation; (5) physical local address (not just a PO Box); (6) 50+ verified Google reviews with recent dates; (7) written itemized estimate including underlayment, flashing, drip edge, ridge vents, and disposal; (8) willingness to pull required Horry County permits. Avoid contractors who demand cash, offer to pay your deductible, or appear only after named storms.

Typical replacement cycles on the Grand Strand: architectural asphalt shingles last 20-25 years in coastal SC (shorter than inland due to UV and salt exposure); metal roofs last 40-70 years; tile lasts 50+ years. Storm damage can shorten any roof's lifespan. Most Myrtle Beach homeowners with asphalt shingles should expect to replace between years 18-25. If your roof is past year 15 and you've lived through one or more named storms, schedule an inspection to document current condition for future insurance claims.

Most reputable Myrtle Beach replacement contractors assist with insurance claims. They document damage with photos, provide adjuster-ready estimates, and coordinate with your insurer. Companies with storm-damage volume — including Weather Shield Roofing, MD Roofing, and Monarch Roofing — are particularly experienced with Horry County claims. Never sign a contract that assigns your insurance proceeds directly to the contractor (AOB), and avoid anyone who offers to waive or pay your deductible (both practices raise fraud flags with SC insurers).
