Energy Savings Calculator for Metal Roofing — Only at ROOFNOW™
Metal roofing is known for its durability, strength, and lifetime performance—but one of its most overlooked benefits is energy efficiency. To help Ontario homeowners calculate real long-term savings, ROOFNOW™ created the Energy Savings Calculator, an exclusive tool that reveals how much can be saved by switching from heat-absorbing asphalt shingles to reflective, engineered G90 steel roofing.
This tool is the first roofing-specific energy calculator built for Ontario’s climate. It takes into account real weather patterns, modern insulation performance, and the true thermal behaviour of steel roofing systems. No other roofing company offers a tool with this level of engineering accuracy.

Why Energy Savings Matter in Ontario
Ontario’s climate creates major energy challenges for homeowners. In summer, attics can exceed 60°C (140°F) under asphalt shingles. In winter, warm indoor air escapes upward and drives furnace usage. Metal roofing helps reduce both cooling and heating costs through superior thermal performance and reflective properties.
The ROOFNOW™ Energy Savings Calculator shows homeowners how much they can save over 5, 10, 20, or even 50 years of ownership.
What Makes This Calculator Unique
Most online energy calculators only estimate generic home energy use. They don’t consider roofing materials, attic temperature, or Ontario’s seasonal weather patterns. The ROOFNOW™ Energy Savings Calculator is built specifically for:
- Ontario climate data
- Realistic home energy costs
- Thermal performance of G90 steel roofing
- Zero-efficiency asphalt shingles
- Summer cooling and winter heat loss trends
Homeowners finally get accurate, roofing-specific energy insights instead of vague generalizations.
How the Calculator Works
The tool estimates how much energy is saved by upgrading to metal roofing. It factors in:
- Roof size
- Material type (asphalt vs metal)
- Local climate zone in Ontario
- Current energy bills
- Expected temperature reductions in the attic
The result: homeowners gain a clear picture of long-term cost savings and return on investment.
The Truth About Asphalt Shingles and Energy Efficiency
Asphalt shingles provide zero energy savings. They absorb heat, increase attic temperatures, and make cooling systems work harder in the summer. They offer no thermal advantage in winter and can actually worsen heat loss when attic airflow is poor.
Metal roofing, especially coated G90 panels, is engineered to reflect solar radiation and stabilize attic temperatures year-round. This performance difference is exactly what the ROOFNOW™ calculator reveals.
Benefits of Using the Energy Savings Calculator
- See real long-term financial savings from a metal roof
- Understand the impact of attic temperature reduction
- Calculate the true lifetime cost vs asphalt shingles
- Make informed, engineering-based decisions
- Plan for future energy costs with realistic numbers
For homeowners considering a long-term roofing solution, this tool provides a clear and accurate financial comparison.
Why ROOFNOW™ Built This Tool
Ontario roofing companies rarely discuss roof energy performance because asphalt shingles offer none. ROOFNOW™ created this calculator to educate homeowners and provide data-driven insights into roofing science, heat transfer, and life-cycle savings.
The tool aligns with ROOFNOW™’s mission to make roofing transparent, measurable, and engineering-based.
How Homeowners Should Use This Tool
- Calculate long-term savings before upgrading to metal roofing
- Compare asphalt vs metal energy performance
- Plan for reduced energy costs over decades
- Understand the full return on investment
- Use alongside the Cost Calculator for total financial clarity
This tool helps Ontario families understand not just the cost of a roof—but the long-term value.
