Vinyl siding outperforms aluminum in nearly every category that matters — maintenance, energy efficiency, durability, and long-term value.
Vinyl siding outperforms aluminum in nearly every category that matters — maintenance, energy efficiency, durability, and long-term value.
For homeowners in Strafford County comparing options, the differences are significant and worth understanding before making a decision.
What NH Homeowners Should Know Before Choosing Between Vinyl and Aluminum
- Maintenance reality: Vinyl siding only needs mild soap and water for periodic cleaning. Aluminum, by contrast, oxidizes and chalks over time and eventually needs repainting — at a cost of up to $12,000 per project.
- Dent and damage risk: Aluminum dents easily from hail, impact, and normal wear. Vinyl is flexible and impact-resistant by design, making it far better suited to the freeze-thaw climate of the Inland Seacoast.
- Fade performance: When asking does vinyl siding fade, the answer depends on product quality — but premium vinyl lines with UV-stabilized pigments maintain color far better than aluminum, which oxidizes and loses its finish over time.
- Energy efficiency: Insulated vinyl siding improves a home’s air tightness by an average of 11% and reduces heating and cooling energy use by 2 to 7% compared to a standard-built home. Aluminum offers no comparable insulation benefit.
- ROI at resale: Vinyl siding delivers an 97% ROI nationally, with an average project cost of $18,000. Composite siding vs vinyl comparisons often come down to budget and climate — but aluminum doesn’t rank competitively against either option for Southern NH homes.
- Fire behavior: Rigid PVC vinyl requires 45% oxygen to sustain combustion, which is higher than the 21% found in normal air. Aluminum conducts heat rapidly, which can be a concern in extreme conditions.
