How much is a sheet of aluminum roof?
The price of a sheet of aluminum roof varies significantly based on several factors, including:
- Thickness: Thicker sheets cost more due to more material.
- Alloy: Stronger or specialized alloys (e.g., 5000 series) are more expensive.
- Profile: Complex profiles (e.g., standing seam, tile profile) can be pricier than standard corrugated.
- Finish/Coating: Color coated aluminum roofing sheet (especially PVDF) is considerably more expensive than mill finish.
- Order Quantity: Bulk purchases often receive discounts.
- Supplier and Location: Prices can vary between manufacturers and regions, with materials sourced from large production hubs often being more competitive.
- Current Aluminum Market Price: Global commodity prices for aluminum fluctuate daily.
Due to these variables, it’s difficult to give an exact per-sheet price without specific dimensions and specifications. However, generally, the raw material cost for aluminum roofing sheet typically ranges from $2.50 to $7.00 per square foot for the material alone, not including installation. For a rough estimate, a standard 3ft x 12ft (about 36 sq ft) sheet might cost anywhere from $90 to $250 or more for the sheet itself, depending heavily on the aforementioned factors. It is always best to request a direct quote from suppliers for your specific project.
What is the disadvantage of using an aluminium roofing sheet?
While aluminum roofing sheet offers many benefits, it does have a few considerations:
- Higher Initial Cost: The most significant disadvantage is its upfront cost, which is typically higher than traditional asphalt shingles.
- Denting: While strong, aluminum can dent from heavy impacts like large hail or falling tree branches, though minor dents are often less noticeable on textured or corrugated profiles.
- Noise: During heavy rain or hail, metal roofs can be noisier than shingled roofs. This can often be mitigated with proper insulation and sound-dampening materials underneath the aluminum roofing sheet.
- Thermal Expansion and Contraction: Aluminum expands and contracts with temperature changes. Proper installation techniques, including floating fasteners or clips, are crucial to allow for this movement and prevent buckling or oil canning (waviness in flat panels).
- Oil Canning (Aesthetic): On flatter or wider panels, a slight waviness (oil canning) can sometimes occur due to stresses in the metal, though it doesn’t affect performance.
Is aluminum roofing cheaper than shingles?
Is aluminum roofing cheaper than shingles? No, generally, aluminum roofing has a higher upfront installation cost compared to asphalt shingles. A typical asphalt shingle roof might cost $4.50 – $7.50 per square foot installed, while an aluminum roofing sheet installation could range from $9.00 – $18.00+ per square foot installed.
However, it’s crucial to consider the life cycle cost. While more expensive initially, aluminum roofing offers:
- Significantly Longer Lifespan: Aluminum roofs can last 50-70 years or more, easily outliving asphalt shingles (15-30 years).
- Lower Maintenance: Requires minimal maintenance compared to shingles, which may need periodic repairs or replacement of damaged sections.
- Energy Efficiency: Aluminum roofing sheet reflects a high percentage of solar radiation, which can lead to significant energy savings on cooling costs, especially with color coated aluminum roofing sheet designed for high reflectivity.
When spread over its extended lifespan and factoring in potential energy savings, aluminum roofing often proves to be a more cost-effective investment in the long run.
