はじめに

Roof Load Calculator — Total roof load from dead and live loads. Enter Roof area (m²), Dead load (kPa), Live load (kPa) to get an instant, accurate result.

計算式

Total roof load = roof area × (dead load + live load), where dead load is the roof's own weight and live load covers snow, maintenance, or other variable loads.

ステップごとの説明

Enter the Roof area (m²).
Enter the Dead load (kPa).
Enter the Live load (kPa).
Click Calculate to see your result instantly.

実例

Example: With Roof area (m²) = 100, Dead load (kPa) = 0.5, Live load (kPa) = 1, the Roof Load Calculator gives Total Load Kn: 150, Combined Load Kpa: 1.5.

よくある質問

What is the difference between dead and live load?

Dead load is the permanent weight of the roof structure and materials; live load is temporary or variable, such as snow accumulation or workers during maintenance.

Should I use this for structural permit calculations?

No, this is a simplified planning estimate — use local code-specified load values and have final designs verified by a structural engineer.

What inputs does the Roof Load Calculator need?

You'll need to provide: Roof area (m²), Dead load (kPa), Live load (kPa). All fields use sensible defaults, so you can see a working example immediately and then adjust the values to match your own numbers.

How accurate is the Roof Load Calculator?

The Roof Load Calculator applies the formula exactly as calculated — Total roof load = roof area × (dead load + live load), where dead load is the roof's own weight and live load covers snow, maintenance, or other variable loads. — so results are precise for the inputs you provide. Accuracy depends on entering correct, realistic input values.

Is the Roof Load Calculator free to use?

Yes, the Roof Load Calculator is completely free, requires no signup, and runs instantly in your browser.
