Metal Roofs vs. Asphalt Shingles Comparison
| Feature | Asphalt Shingles (GAF/CertainTeed) | Standing Seam Metal |
|---|---|---|
| Average Lifespan | 15 to 30 years depending on grade (e.g., Architectural vs. 3-Tab). | 50 to 70+ years with proper maintenance. |
| Hail & Wind Resistance | Good resistance up to 130mph (Class F wind rating). Susceptible to heavy hail bruising. | Exceptional. Highly resistant to high winds and hail. Class 4 impact resistance common. |
| Upfront Cost | Lower initial investment. Highly cost-effective for standard residential profiles. | Higher initial investment (often 2x-3x asphalt), but lowest lifetime cost. |
| Energy Efficiency | Moderate. Modern shingles offer reflective granules to reduce attic heat. | Excellent. Highly reflective, significantly reducing cooling costs in NC summers. |
| Best Suited For | Homeowners looking for high curb appeal on a budget or prepping a house for sale. | Forever homes, rural properties, and homeowners prioritizing extreme durability. |

Guilford & Forsyth County Roofing Codes (2026)
North Carolina enforces strict building codes for roof replacements to protect homes against high winds and severe weather. When Arthur's Roofing installs a new system, we guarantee full compliance with local municipality requirements:
- Permit Requirements: A structural permit is required for residential roof replacements in Greensboro, High Point, and Winston-Salem. We pull all necessary permits and manage the inspection process.
- Tear-Off Mandates: Local codes typically prohibit installing a third layer of shingles. We advocate for a complete tear-off down to the decking on every job to inspect for hidden wood rot.
- Ice & Water Barrier: While not universally required in all NC counties, we install heavy-duty ice and water shields in all valleys and penetrations to exceed baseline codes and prevent winter leaks.
- Drip Edge Installation: Code requires a metal drip edge installed along the eaves and rakes. This directs water into the gutters and prevents fascia rot.
The 5 Components of a Complete Roofing System
A roof is not just shingles. It is a complete, integrated system designed to protect your home from water intrusion and manage attic moisture. Arthur's Roofing installs all five critical components on every roof replacement:
- Ice & Water Shield: A waterproof membrane installed at the eaves, in valleys, and around penetrations (chimneys, skylights) to prevent leaks from ice damming and wind-driven rain.
- Synthetic Underlayment: A highly durable, water-resistant layer applied over the entire roof deck to provide a secondary barrier against moisture, replacing outdated organic felt paper.
- Starter Strip Shingles: Specialized adhesive shingles installed along the eaves and rakes to lock down the first row of primary shingles, preventing wind blow-off.
- Primary Shingles (Architectural/Designer): The visible layer of protection. We use premium brands like GAF Timberline HDZ and CertainTeed Landmark for maximum durability and aesthetic appeal.
- Ridge Ventilation: A critical exhaust system installed along the peak of the roof to allow hot, moist air to escape the attic, preventing wood rot and extending the life of the shingles.
