Standing Seam Metal Roofing in Myrtle Beach, SC
The ultimate roofing solution for coastal South Carolina homes. Standing seam metal roofing delivers hurricane-force wind resistance up to 180 mph, complete salt air corrosion protection, and a 50-70 year lifespan that outlasts any other roofing material.
What is Standing Seam Metal Roofing?
Standing seam metal roofing is a premium roofing system characterized by raised interlocking seams that connect adjacent metal panels. Unlike exposed fastener metal roofing where screws penetrate the panel surface, standing seam uses a concealed fastener system where clips attach the panels to the roof deck, with the seams hiding all attachment points.
The result is a continuous, sleek roofing surface with no exposed screws, washers, or penetrations that can corrode, back out, or create leak points over time. This design makes standing seam the most water-tight and durable metal roofing option available, which is why it has become the preferred choice for both residential and commercial buildings in hurricane-prone coastal areas like Myrtle Beach, South Carolina.
The term standing seam refers to the raised vertical ribs that run from the ridge to the eave of the roof. These ribs typically stand 1 to 2 inches tall and create the distinctive linear aesthetic that defines this roofing style. The seams not only provide visual appeal but serve a critical functional purpose, channeling water down the roof surface while creating strong mechanical connections between panels that resist wind uplift.
Key Characteristics of Standing Seam Metal Roofing
- Concealed fasteners: All clips and fasteners are hidden beneath the seam, eliminating exposed penetration points
- Raised seams: Vertical ribs 1-2 inches tall run from ridge to eave, channeling water and strengthening connections
- Interlocking panels: Adjacent panels connect mechanically through snap-lock or crimped seams
- Thermal movement: Floating clip systems allow panels to expand and contract without stress
- Premium finishes: Kynar 500/Hylar 5000 coatings provide 30-40 year color and performance warranties
Why Standing Seam Metal Roofing is Ideal for Myrtle Beach
Myrtle Beach presents unique roofing challenges that standing seam addresses better than any other roofing material. Here is why coastal South Carolina homeowners are choosing standing seam in record numbers.
Hurricane Protection
Myrtle Beach lies in South Carolina Hurricane Alley, with direct exposure to Atlantic hurricanes from June through November. Since 1851, over 30 hurricanes have made landfall within 100 miles of Myrtle Beach, including devastating storms like Hugo (1989) and Florence (2018).
Standing seam metal roofing provides the highest wind resistance of any roofing material. Mechanical lock systems achieve ratings of 180+ mph, exceeding even Category 5 hurricane wind speeds. The concealed fastener design eliminates the weak points that cause other roofing materials to fail in high winds, as there are no exposed screws to back out or shingles to lift.
Our standing seam installations have survived multiple major hurricanes without a single panel loss.
Salt Air Resistance
Properties within 1,500 feet of the Atlantic Ocean face constant salt air exposure that accelerates corrosion on most building materials. Exposed fastener metal roofing is particularly vulnerable, as the screws and washers often corrode within 10-15 years, leading to leaks and panel loss.
Standing seam eliminates this vulnerability through concealed fastening. For oceanfront properties, we recommend aluminum standing seam, which naturally resists corrosion and never rusts. For homes further inland, Galvalume or Kynar 500 coated steel provides excellent protection at a lower cost point.
Aluminum standing seam carries no corrosion concerns, making it ideal for Cherry Grove, Surfside Beach, and Garden City oceanfront homes.
Superior Energy Efficiency
South Carolina summers bring relentless heat and humidity, with cooling costs representing a major portion of household energy bills. Standard asphalt shingles absorb up to 95% of solar radiation, superheating your attic to 150-170 degrees and forcing your AC to work overtime.
Cool metal roofing with reflective Kynar 500 finishes reflects up to 70% of solar radiation, reducing attic temperatures by 30-50 degrees. Homeowners typically report 20-25% reductions in summer cooling costs. ENERGY STAR certified options qualify for federal tax credits and utility rebates, further improving the financial return.
Light-colored standing seam can reduce cooling costs by hundreds of dollars annually in Myrtle Beach hot climate.
Humidity & Mold Resistance
Myrtle Beach average humidity hovers around 70-80%, creating ideal conditions for mold, mildew, and algae growth on roofing materials. Asphalt shingles are particularly susceptible, often developing unsightly black streaks within just a few years that detract from curb appeal and indicate organic growth.
Standing seam metal roofing completely resists mold, mildew, and algae growth. The smooth, non-porous surface sheds water instantly and provides no foothold for organic materials. This means your roof maintains its clean, attractive appearance decade after decade without chemical treatments or frequent cleaning.
No more black streaks or moss growth that plague shingle roofs in our humid coastal climate.
Standing Seam Panel Profiles and Options
Standing seam metal roofing comes in several profile configurations, each designed for specific applications and performance requirements. Understanding these options helps you choose the right system for your Myrtle Beach home.
Snap-Lock Standing Seam
Snap-lock panels feature a male leg on one panel and a female leg on the adjacent panel that snap together during installation. This is the most popular residential standing seam profile due to faster installation and lower labor costs. Quality snap-lock systems achieve wind ratings of 140+ mph, suitable for most Myrtle Beach residential applications.
Best For:
- - Residential homes with 4:12+ pitch
- - Projects requiring faster installation
- - Budget-conscious homeowners
- - Areas with 140 mph or lower wind requirements
Specifications:
- - Minimum pitch: 3:12
- - Wind rating: 110-150 mph
- - Seam height: 1.0-1.75 inches
- - Panel width: 12-18 inches typical
Mechanical Lock (Double-Lock) Standing Seam
Mechanical lock panels require an electric or hand seaming tool to crimp the male and female legs together after installation. This creates the tightest possible seam rated for the highest wind speeds and lowest roof pitches. Mechanical lock is the premium choice for coastal hurricane zones and commercial applications.
Best For:
- - Oceanfront and high-exposure properties
- - Low-slope roofs (down to 1:12)
- - Maximum hurricane protection
- - Commercial and institutional buildings
Specifications:
- - Minimum pitch: 1:12 (with sealant)
- - Wind rating: 150-180+ mph
- - Seam height: 1.5-2.0 inches
- - Panel width: 12-18 inches typical
Nail Flange (Fastener Flange) Standing Seam
Nail flange panels have a flat nailing strip along one edge that gets fastened directly to the deck before the next panel covers it. This creates a concealed fastener appearance similar to clip-attached systems but at a lower cost. However, the rigid attachment limits thermal expansion, making this system best for shorter panel runs.
Best For:
- - Shorter roof runs (under 30 feet)
- - Residential retrofits
- - Budget-friendly concealed fastener option
- - DIY-friendly installation
Specifications:
- - Minimum pitch: 3:12
- - Wind rating: 90-120 mph
- - Seam height: 0.75-1.5 inches
- - Panel width: 12-16 inches typical
Standing Seam Materials: Steel, Aluminum, Copper, and Zinc
The metal substrate you choose affects durability, corrosion resistance, appearance, and cost. Here is how each material performs in coastal South Carolina conditions.
Galvalume Steel (Most Popular)
Composition
Steel core with aluminum-zinc alloy coating (55% aluminum, 45% zinc by weight)
Lifespan
50-60 years with Kynar 500 finish; 30-40 year finish warranty typical
Best For
Homes 1,500+ feet from ocean; best value for most Myrtle Beach properties
Galvalume steel offers the best combination of strength, corrosion resistance, and affordability. The aluminum-zinc coating provides excellent barrier protection, while Kynar 500 or Hylar 5000 paint finishes add UV protection and color stability. We recommend 24-gauge thickness for residential applications.
Aluminum (Premium Coastal Choice)
Composition
Pure aluminum alloy (typically 3003-H14 or 3105-H14)
Lifespan
70+ years; aluminum naturally resists corrosion and never rusts
Best For
Oceanfront properties within 1,500 feet of salt water
Aluminum is the ultimate choice for coastal corrosion resistance. It forms a protective oxide layer that prevents further oxidation, meaning it will never rust or corrode even in direct salt spray. The lighter weight (about 1/3 of steel) reduces structural load. We typically specify .032 or .040 thickness for residential standing seam.
Copper (Luxury & Historic Applications)
Composition
Pure copper sheet (16-20 oz per square foot typical)
Lifespan
100+ years; develops distinctive green patina over time
Best For
Historic restorations, luxury homes, architectural accents
Copper is the longest-lasting roofing material available and develops a beautiful verdigris patina that many homeowners prize. It requires no coating or paint and actually becomes more corrosion-resistant as it ages. The premium cost (3-4x steel) limits it to high-end applications, but it can literally last forever with minimal maintenance.
Zinc (European Elegance)
Composition
Titanium-zinc alloy (typically VMZINC or RHEINZINK)
Lifespan
80-100+ years; self-healing patina repairs minor scratches
Best For
Modern architecture, environmentally conscious projects
Zinc offers exceptional longevity with a distinctive matte gray appearance that weathers to a soft patina. It is self-healing, meaning minor scratches will naturally repatinate rather than rust. Zinc is 100% recyclable and requires the least energy to produce of any roofing metal. Popular for modern architectural designs.
Standing Seam vs Exposed Fastener Metal Roofing
Many homeowners research metal roofing and encounter significantly lower prices for exposed fastener systems. Understanding the differences is crucial for making the right choice, especially in coastal South Carolina.
| Feature | Standing Seam | Exposed Fastener |
|---|---|---|
| Fastener System | Concealed clips hidden under seams | Screws penetrate through panel face |
| Wind Rating | 140-180+ mph | 90-120 mph typical |
| Coastal Performance | Excellent - no exposed metal to corrode | Poor - fasteners corrode in salt air |
| Thermal Movement | Floating clips allow expansion/contraction | Rigid fastening can cause oil canning |
| Lifespan | 50-70 years | 25-40 years |
| Leak Risk | Very low - no panel penetrations | Higher - washers degrade over time |
| Maintenance | Minimal - no fasteners to inspect | Requires periodic fastener inspection and replacement |
| Initial Cost | $12-18 per square foot | $6-10 per square foot |
| Lifetime Cost | Lower - lasts 2x longer | Higher - needs replacement sooner |
Our Recommendation for Myrtle Beach
For Myrtle Beach coastal properties, we strongly recommend standing seam over exposed fastener systems. The concealed fastener design eliminates the corrosion and maintenance concerns that plague exposed fastener roofs in our salt air environment. While the upfront cost is higher, the 50-70 year lifespan and superior storm performance provide better long-term value. For budget-conscious projects, consider stone-coated metal shingles as an alternative that still outperforms exposed fastener systems.
Hurricane Wind Ratings: Understanding 140-180 MPH Protection
Wind ratings for standing seam metal roofing indicate the maximum wind speed the system can withstand without panel failure, based on standardized testing. Here is what these ratings mean for Myrtle Beach homeowners.
Hurricane Categories vs Standing Seam Ratings
74-110 mph winds
All standing seam systems provide full protection
111-129 mph winds
Snap-lock (140 mph) and mechanical lock (180 mph) both exceed requirements
130-156 mph winds
Quality snap-lock (140+ mph) provides margin; mechanical lock (180 mph) ideal
157+ mph winds
Mechanical lock standing seam (180+ mph) is the only residential roofing rated for Cat 5
How Wind Ratings Are Determined
Wind ratings come from standardized tests including ASTM E1592 (air pressure), UL 580/90 (uplift), and FM 4471 (Factory Mutual). These tests simulate hurricane conditions by applying positive and negative air pressure cycles to mounted panels until failure occurs.
Important: Real-world performance depends on proper installation. Clip spacing, fastener patterns, and edge details must follow manufacturer specifications to achieve rated wind resistance.
Enhanced Wind Zones in SC
South Carolina building codes designate Myrtle Beach as Wind Zone II, requiring minimum 110 mph wind resistance. However, specific exposure categories (open terrain, elevation, proximity to water) may increase requirements.
We recommend exceeding minimums given our direct hurricane exposure. A 180 mph rated mechanical lock system provides maximum protection and often qualifies for insurance discounts of 15-35%.
Salt Air and Coastal Corrosion Resistance
Corrosion is the silent killer of roofing materials in coastal South Carolina. Salt-laden air accelerates oxidation, attacks metal fasteners, and degrades protective coatings faster than inland environments. Standing seam metal roofing addresses these challenges through careful material selection and concealed fastener design.
Corrosion Zones in Myrtle Beach
0-500 feet from ocean
Direct salt spray exposure. Aluminum standing seam strongly recommended. Stainless steel clips and fasteners required.
500-1,500 feet from ocean
Significant salt air exposure. Aluminum preferred; quality Galvalume with Kynar 500 acceptable. Enhanced corrosion-resistant fasteners recommended.
1,500-3,000 feet from ocean
Moderate salt influence. Galvalume steel with Kynar 500 performs well. Standard corrosion-resistant fasteners acceptable.
3,000+ feet from ocean
Minimal direct salt exposure. All standing seam materials perform well with standard finishes and fasteners.
Why Concealed Fasteners Matter in Coastal Areas
In exposed fastener metal roofing, hundreds of screws penetrate the panel surface. Each screw head, washer, and penetration point becomes a corrosion target in salt air. The rubber or EPDM washers degrade under UV and salt exposure, typically failing within 10-15 years. Once washers fail, water infiltrates around the fastener, accelerating corrosion from the inside out and causing leaks.
Standing seam eliminates this vulnerability entirely. The concealed clip system means no fasteners penetrate the roofing surface. Even the clips themselves are protected beneath the interlocking seams, shielded from direct salt spray and UV exposure. This design maintains water-tightness and structural integrity for the full 50-70 year lifespan.
Special Considerations for Oceanfront Properties
For properties directly on the beach in Cherry Grove, Surfside Beach, Garden City, and other oceanfront areas, we specify: (1) Aluminum substrate only, (2) Stainless steel clips and accessories, (3) Enhanced sealant at all penetrations, (4) More frequent inspection schedule during first 5 years. These specifications ensure your standing seam roof will outlast multiple generations in the harshest coastal conditions.
South Carolina Building Code Compliance for Metal Roofing
South Carolina has adopted the 2021 International Building Code (IBC) and 2021 International Residential Code (IRC) with state-specific amendments that address our coastal hurricane exposure. Understanding these requirements ensures your standing seam installation meets all legal standards.
Wind Design Requirements
- Wind Speed: Myrtle Beach basic wind speed is 150 mph (Ultimate Design Wind Speed per ASCE 7-16)
- Exposure Category: Coastal areas typically Exposure C or D, increasing wind pressure coefficients
- Component Testing: Roofing materials must be tested per ASTM E1592, UL 580, or equivalent
- Edge and Corner Zones: Enhanced fastening patterns required in high-pressure zones
Metal Roofing Specific Requirements
- Underlayment: Synthetic underlayment meeting ASTM D226 Type II or higher required
- Minimum Pitch: 3:12 for most metal roofing; low-slope systems (1:12) require special provisions
- Flashing: Code-compliant flashing at all penetrations, valleys, and transitions
- Fire Rating: Class A, B, or C fire rating required depending on location
Permit and Inspection Requirements
- Building Permit: Required for all roof replacements in Horry County
- Inspections: Typically sheathing/deck inspection and final roof inspection required
- Contractor License: Must be SC licensed residential or commercial contractor
- HOA Approval: Many Myrtle Beach communities require architectural review
Weather Shield handles all permit applications and inspections as part of our comprehensive installation service. We ensure every standing seam installation meets or exceeds South Carolina building codes, with full documentation for your records and insurance requirements.
Energy Efficiency: Cool Metal Roofing Benefits
In South Carolina subtropical climate, cooling costs represent the largest portion of household energy bills. Standing seam metal roofing with reflective finishes dramatically reduces cooling loads, providing significant financial and environmental benefits.
Solar Reflectance
Standard asphalt shingles absorb 90-95% of solar radiation, superheating your attic to 150-170 degrees on summer days. This heat radiates into your living space, forcing your AC to run continuously.
Cool metal roofing with light-colored Kynar 500 finishes reflects up to 70% of solar radiation. This keeps attic temperatures 30-50 degrees cooler, dramatically reducing the heat transfer into your home.
Thermal Emissivity
Metal roofing not only reflects solar energy but also releases absorbed heat more efficiently than asphalt. This thermal emissivity helps your roof cool quickly after sunset, reducing overnight heat accumulation.
The combination of high reflectance and high emissivity makes metal roofing the most energy-efficient option for Myrtle Beach hot, humid climate.

Standing Seam Installation Process
Professional installation is critical for standing seam performance. Our certified installers follow manufacturer specifications and industry best practices to ensure your roof delivers its full 50-70 year potential.
Pre-Installation Consultation
We begin with a comprehensive roof evaluation including measurements, structural assessment, and identification of any existing damage. We discuss panel profiles, materials, colors, and provide detailed cost estimates. This consultation typically takes 1-2 hours and is completely free.
Existing Roof Removal
We remove all existing roofing materials down to the deck, allowing full inspection for damage, rot, or structural issues. Damaged decking is replaced with new OSB or plywood to ensure a solid substrate for the standing seam system.
Deck Preparation & Underlayment
We install high-temperature synthetic underlayment designed specifically for metal roofing. In coastal areas, we add peel-and-stick membrane in valleys, at eaves, and around penetrations for enhanced water protection. Proper ventilation is verified or improved as needed.
Eave and Rake Trim Installation
Precision installation of drip edge, eave trim, and rake trim creates clean edges and proper water management. Custom brake-formed trim pieces ensure seamless transitions and a finished appearance.
Panel Installation
Panels are cut to precise length (often fabricated on-site with portable roll-forming equipment for seamless runs). Clips are installed at specified spacing for the wind zone, then panels are attached and seamed. Mechanical lock systems require field-seaming with electric or manual tools.
Flashing & Penetration Details
All penetrations (vents, pipes, skylights) receive custom-fabricated flashing with sealant. Valley flashing, ridge cap, and transition flashing are installed to manufacturer specifications. This detail work is critical for long-term weather-tightness.
Final Inspection & Cleanup
We conduct a comprehensive quality inspection of all seams, flashings, and details. The property is thoroughly cleaned with magnetic sweepers collecting any metal debris. We walk you through the completed installation and provide all warranty documentation.
Typical Installation Timeline
Most residential standing seam installations take 3-5 days depending on roof size, complexity, and weather conditions. Larger or more complex projects may require 1-2 weeks. We work efficiently while never compromising quality to minimize disruption to your household.
Standing Seam Lifespan: 50-70+ Years of Protection
The exceptional longevity of standing seam metal roofing is one of its most compelling advantages. While asphalt shingles typically last only 15-20 years in coastal South Carolina, standing seam provides 50-70+ years of reliable protection.
Lifespan by Material
- Aluminum Standing Seam70+ years
- Galvalume Steel (Kynar 500)50-60 years
- Copper100+ years
- Zinc80-100 years
- Asphalt Shingles (comparison)15-20 years
Why Standing Seam Lasts So Long
- No exposed fasteners to corrode or back out
- Floating clip system prevents thermal stress
- Kynar 500 finishes resist UV, salt, and chalking
- Metal substrate does not crack, curl, or rot
- Interlocking seams maintain weather-tightness
- No organic components to support mold/algae
The Last Roof You Will Ever Need
For most homeowners, standing seam is the last roof they will ever install. A 50-year-old homeowner who installs standing seam today will likely never need another roof replacement. Compare this to asphalt shingles that would require 3-4 replacements over the same period, and the lifetime cost advantage becomes clear.
Maintenance Requirements for Standing Seam Metal Roofing
One of standing seam greatest advantages is minimal maintenance requirements. Unlike asphalt shingles that require periodic moss treatment, granule inspection, and eventual replacement, standing seam largely takes care of itself.
Annual Maintenance Checklist
- Visual Inspection: Walk the property and inspect for debris accumulation, physical damage from fallen branches, or any visible issues
- Gutter Cleaning: Clear gutters and downspouts of leaves and debris to ensure proper drainage
- Flashing Check: Inspect sealant at penetrations and transitions; reseal if showing wear
- Trim Vegetation: Cut back overhanging branches that could scratch panels or deposit debris
Occasional Cleaning
Standing seam metal roofing is largely self-cleaning, with rain washing away most dirt and debris. However, areas with heavy tree cover or low-slope sections may benefit from occasional cleaning.
Recommended Cleaning Method:
- - Use garden hose with moderate pressure
- - Soft brush for stubborn spots
- - Mild detergent (dish soap) if needed
- - Never use abrasive cleaners or pressure washers
- - Clean from ridge to eave, working with gravity
Compare to Asphalt Shingle Maintenance
Asphalt shingles require significantly more maintenance: annual moss/algae treatment, periodic granule loss inspection, addressing lifted or curled shingles, and eventual replacement every 15-20 years. The near-zero maintenance of standing seam metal roofing represents significant time and cost savings over its 50-70 year lifespan.

Frequently Asked Questions About Standing Seam Metal Roofing
What is the difference between snap-lock and mechanical lock standing seam?
Snap-lock panels have a male and female leg that snap together during installation, making them faster to install and ideal for residential applications with standard wind requirements. Mechanical lock (also called field-locked or double-lock) panels require a seaming tool to crimp the panels together, creating a tighter seal rated for higher wind speeds (180+ mph) and lower roof pitches. For Myrtle Beach hurricane zones, we typically recommend mechanical lock for maximum protection, though snap-lock systems rated for 140+ mph are suitable for many residential applications.
Is standing seam metal roofing good for coastal homes in Myrtle Beach?
Standing seam is the premium choice for coastal Myrtle Beach homes. The concealed fastener system eliminates corrosion points that plague exposed fastener systems in salt air environments. Aluminum standing seam naturally resists corrosion and never rusts, making it ideal for oceanfront properties. Galvalume or Kynar 500 coated steel offers excellent protection for homes further from the water at a lower cost. The raised seam profile also channels water efficiently, critical during coastal storms with driving rain.
How long does standing seam metal roofing last in South Carolina?
Standing seam metal roofing lasts 50-70+ years in South Carolina when properly installed with quality materials. Aluminum systems last longest (70+ years) due to complete corrosion immunity. Steel with Kynar 500/Hylar 5000 coating lasts 50-60 years with 30-40 year finish warranties. Copper and zinc can exceed 100 years. This is 3-4 times longer than asphalt shingles, which typically last only 15-20 years in our humid coastal climate with salt air and intense UV exposure.
What wind rating should I choose for standing seam in Myrtle Beach?
South Carolina building codes require minimum 110 mph wind ratings in coastal zones. However, given Myrtle Beach direct hurricane exposure, we recommend standing seam systems rated for 140-180 mph. Category 3 hurricanes bring 111-129 mph sustained winds; Category 4 reaches 130-156 mph. Mechanical lock standing seam achieves 180+ mph ratings when installed with enhanced clip patterns. The extra investment provides peace of mind and often qualifies for insurance premium discounts of 15-35%.
Does standing seam metal roofing qualify for insurance discounts in SC?
Yes! Standing seam metal roofing typically qualifies for the highest insurance discounts available in South Carolina due to Class A fire rating, Class 4 impact resistance (when applicable), and superior wind ratings. Homeowners commonly receive 15-35% premium reductions. Additional discounts apply for secondary water barriers, enhanced fastening patterns, and hurricane straps. Document your installation specifications and contact your insurer before and after installation to maximize savings.
Can standing seam be installed over my existing roof in Myrtle Beach?
While overlay installation is technically possible with proper furring strips, we generally recommend full tear-off for standing seam installations. This allows inspection and repair of the roof deck, installation of proper underlayment rated for metal roofing, and ensures optimal long-term performance. South Carolina building codes also limit the total number of roof layers. A tear-off adds cost upfront but provides better value over the 50-70 year lifespan of standing seam.
What colors are available for standing seam metal roofing?
Standing seam metal roofing is available in 40+ colors with Kynar 500/Hylar 5000 finishes that resist fading, chalking, and corrosion. Popular colors in Myrtle Beach include Charcoal Gray, Slate Blue, Forest Green, Colonial Red, Bronze, and various earth tones that complement coastal architecture. Light colors like Bright White or Light Stone provide maximum solar reflectance for energy savings. We provide color samples and can coordinate with your exterior design.
How does standing seam compare to asphalt shingles for cost?
Standing seam costs 2-3x more than architectural asphalt shingles upfront ($12-18 vs $5-8 per square foot installed). However, standing seam lasts 50-70 years versus 15-20 years for shingles in coastal SC, meaning you would replace shingles 3-4 times over the same period. Factor in reduced maintenance, energy savings (20-25% cooling reduction), and insurance discounts (15-35%), and standing seam often provides better lifetime value. Many homeowners finance the difference and achieve positive cash flow through energy and insurance savings.
Is standing seam metal roofing noisy during rain and storms?
No! This is the most common misconception about metal roofing. When installed over solid roof decking with proper synthetic underlayment and attic insulation, standing seam is actually quieter than asphalt shingles during rain. The solid substrate and insulation layers absorb sound effectively. In blind studies, homeowners often cannot distinguish metal from shingle roofs during rainstorms. The lack of exposed fasteners in standing seam systems also eliminates potential noise from fastener movement.
What maintenance does standing seam metal roofing require?
Standing seam requires minimal maintenance compared to other roofing materials. Annual inspections should check for debris accumulation in valleys, ensure flashing remains sealed, and verify no physical damage from fallen branches or severe weather. Occasional cleaning with mild detergent removes organic growth. The Kynar 500 finish resists dirt accumulation. No granule loss, no moss growth, no curling or cracking like shingles. This low maintenance is one of the key advantages of standing seam over its 50-70 year lifespan.
Can solar panels be installed on standing seam metal roofing?
Yes, standing seam is actually ideal for solar panel installation! S-5! clamps attach directly to the raised seams without penetrating the roof surface, eliminating leak concerns and maintaining warranty coverage. This non-penetrating mounting is faster to install, easily repositioned, and completely reversible. The 50-70 year lifespan of standing seam means you will not need to remove panels for roof replacement during the solar system lifetime, unlike asphalt shingle roofs that may need replacement after 15-20 years.
What is the minimum roof pitch for standing seam in South Carolina?
Mechanical lock standing seam can be installed on pitches as low as 1:12 (nearly flat) when specified for low-slope applications with proper sealant in seams. Snap-lock systems typically require minimum 3:12 pitch. Standard residential applications work well on 4:12 and steeper. Low-slope installations require enhanced water management and underlayment. South Carolina building codes require roofing systems appropriate for the specific pitch. We evaluate each project and recommend the appropriate panel profile for your roof geometry.
