Replacement Roof: The Complete Guide for Coastal Homeowners
Everything you need to know about getting a replacement roof in Myrtle Beach and coastal South Carolina. Expert guidance from the area's highest-rated roofing contractor.
What's In This Replacement Roof Guide
1. What Is a Replacement Roof?
A replacement roof is a complete tear-off and installation of a new roofing system. Unlike repairs that fix isolated problems, a replacement roof removes all existing materials down to the decking and installs an entirely new protective system—from underlayment to ridge cap.
For coastal South Carolina homeowners, a replacement roof isn't just about aesthetics. It's your home's primary defense against hurricanes, heavy rainfall, salt air corrosion, and intense UV exposure. A properly installed replacement roof protects your family, belongings, and largest investment for decades.
The typical replacement roof in Myrtle Beach includes:
- Complete tear-off of existing roofing materials
- Decking inspection and repair of any rotted or damaged wood
- Ice & water shield in valleys and around penetrations
- Synthetic underlayment across the entire roof deck
- New drip edge and flashing at all edges and penetrations
- Primary roofing material (shingles, metal, etc.)
- Ridge vents and caps for proper ventilation
- Manufacturer and workmanship warranties
2. Signs You Need a Replacement Roof
How do you know when repairs aren't enough? These warning signs indicate it's time for a full replacement roof:
Age Over 15-20 Years
Asphalt shingles in coastal SC typically last 15-20 years due to salt air, humidity, and storms. If your roof is approaching this age, it's time to plan.
Multiple Leaks
One leak might be repairable, but multiple leaks in different areas often indicate systemic failure requiring full replacement.
Missing or Curling Shingles
When shingles curl, crack, or blow off frequently, the roofing material has reached end-of-life and repairs won't provide lasting protection.
Granules in Gutters
Finding excessive granules (looks like coarse sand) in gutters means shingles are deteriorating and losing their protective coating.
Daylight Through Roof Boards
If you can see light coming through your attic roof boards, you have serious structural issues requiring immediate replacement.
Sagging Roof Deck
A sagging or wavy roof line indicates structural damage to the decking underneath, often from prolonged moisture damage.
Not Sure If You Need Replacement?
We offer free, no-obligation roof inspections. Our certified inspector will assess your roof's condition and give you honest recommendations—whether that's repair, maintenance, or replacement. Call (843) 877-5539 to schedule.
3. Replacement Roof vs. Repair: Which Do You Need?
Not every roof problem requires full replacement. Here's how to decide:
Repair Makes Sense When...
- Roof is under 10-12 years old
- Damage is isolated to one area
- Single leak with identifiable source
- Few missing shingles from storm
- Minor flashing issues
- Rest of roof in good condition
Replacement Makes Sense When...
- Roof is 15-20+ years old
- Damage is widespread across roof
- Multiple leaks in different areas
- Shingles are curling, cracking, or bare
- Sagging or structural concerns
- Repair costs exceed 25% of replacement

5. Coastal Climate Considerations for Your Replacement Roof
Myrtle Beach's coastal environment creates unique challenges that inland homeowners never face. Your replacement roof must be designed to handle:
Important: Coastal roofs age 25-30% faster than inland roofs. A roof lasting 25 years in Columbia may only last 15-20 years in Myrtle Beach.
Salt Air Corrosion
The Challenge:
Properties within 1,500 feet of saltwater experience accelerated material degradation. Standard metals corrode, shingles deteriorate faster.
Our Solution:
We use corrosion-resistant fasteners, coastal-rated materials, and enhanced sealants designed for salt environments.
Hurricane-Force Winds
The Challenge:
Myrtle Beach averages one hurricane threat per year. Standard roofing can fail at 70+ mph winds, leaving homes exposed.
Our Solution:
High-wind rated shingles (130+ mph), 6-nail installation pattern, and enhanced starter strips provide maximum wind resistance.
Heavy Rainfall
The Challenge:
SC's 50+ inches annual rainfall tests waterproofing systems. Improper installation leads to leaks and water damage.
Our Solution:
Ice & water shield in valleys, proper flashing details, and quality underlayment prevent water infiltration.
Intense UV Exposure
The Challenge:
Coastal sunlight accelerates shingle aging by 25-30%. Granules wear faster, reducing protection and lifespan.
Our Solution:
UV-resistant shingles, reflective options, and proper attic ventilation combat heat damage.
High Humidity
The Challenge:
70-80% humidity promotes algae growth, moss, and mold on roofs. This affects appearance and can damage materials.
Our Solution:
Algae-resistant shingles with copper granules prevent black streaking and biological growth.
Building Code Requirements
The Challenge:
Coastal SC has stricter building codes requiring enhanced wind resistance, proper permitting, and inspections.
Our Solution:
We're fully familiar with Horry County codes and ensure every installation exceeds minimum requirements.

8. Replacement Roof FAQs
Common questions about getting a replacement roof in coastal South Carolina
How do I know if I need a replacement roof or just repairs?
If damage is limited to a small area (a few shingles, one leak), repair usually makes sense. But widespread damage, roofs over 15-20 years old, multiple leaks, or visible deterioration typically warrant full replacement. Our free inspection determines exactly what your roof needs—we never push unnecessary replacement. Call (843) 877-5539 for honest assessment.
How much does a replacement roof cost in Myrtle Beach?
Most Myrtle Beach homeowners invest between $10,500-$16,500 for architectural shingles on an average-sized home (2,000-3,000 sq ft). Factors affecting price include roof size, pitch, complexity, material choice, and decking condition. Metal roofing costs more upfront but lasts 50+ years. We provide free detailed estimates with transparent pricing—call (843) 877-5539.
How long does it take to install a replacement roof?
Most residential replacement roofs are completed in 1-2 days. Larger homes, complex designs, or extensive decking repairs may take 3-4 days. Weather delays can extend timelines. We always communicate clearly about scheduling and keep you informed throughout the process.
Will insurance cover my replacement roof?
Insurance covers replacement when damage results from covered events (storms, hail, fallen trees)—not normal wear. We work directly with insurance companies, document damage thoroughly, meet with adjusters, and help maximize your claim. Many customers pay only their deductible for storm-related replacements. Call (843) 877-5539 for a free insurance assessment.
What roofing material is best for Myrtle Beach's coastal climate?
About 90% of our customers choose architectural shingles—they offer excellent wind resistance (130+ mph), algae resistance, and 25-30 year warranties at reasonable cost. For maximum durability, metal roofing lasts 50-70 years and handles salt air exceptionally well. We recommend the best option for your specific situation and budget.
How do I choose a reliable roofing contractor?
Look for: 10+ years in business, proper licensing and insurance, manufacturer certifications (like GAF Master Elite), strong reviews, and physical local address. Avoid storm chasers, companies offering to cover your deductible (that's insurance fraud), and those requiring full payment upfront. Weather Shield Roofing has served Myrtle Beach since 2010 with a 5.0-star rating.
What warranties come with a replacement roof?
You receive two warranties: manufacturer warranty covering materials (typically 25-50 years depending on product) and our workmanship warranty covering installation. As GAF Master Elite contractors, we offer enhanced warranty options including the Golden Pledge Warranty with 50-year material coverage and 25-year workmanship protection.
Should I get multiple quotes for my replacement roof?
Absolutely—we recommend getting at least 3 quotes. This helps you understand fair pricing and compare contractors. When comparing, ensure quotes include the same scope (tear-off, decking inspection, warranty level). The lowest bid isn't always best—ask how they're cutting corners. We're happy to be one of your quotes. Call (843) 877-5539.
What financing options are available for a replacement roof?
Weather Shield Roofing offers flexible financing including 0% APR options for qualified buyers, payment plans from 12-144 months, and quick 5-minute approval. We work with multiple lenders to find terms that fit your budget. Don't let cost delay necessary protection for your home.
Why do roofs age faster in Myrtle Beach?
Coastal roofs age 25-30% faster than inland roofs due to: salt air corrosion, hurricane-force winds, intense UV exposure, heavy rainfall (50+ inches annually), and 70-80% humidity. An asphalt roof lasting 25 years in Columbia may only last 15-20 years in Myrtle Beach. This is why material selection and proper installation are critical for coastal homes.
Can I stay in my home during roof replacement?
Yes, you can stay home during most replacements. Expect noise during work hours (typically 7am-6pm), and we'll need driveway access for materials and debris removal. We protect your landscaping, clean up daily, and use magnetic sweepers to collect nails. Many customers go about their normal routine during installation.
What happens if it rains during my replacement roof project?
We monitor weather forecasts closely and won't start work if rain is likely before we can waterproof. If unexpected rain occurs, we immediately cover exposed areas with tarps. Your home is never left unprotected. We may pause work until conditions improve, but always ensure your property stays dry.
