Enter field measurements. Imperial lengths take feet and inches. Unit conversion happens before the reviewed formula is applied.
All values can be refined when you edit the estimate. This tool does not replace field verification or local requirements.
Snow load calculator publishes formula ROOF-SNOW-001 version 1.0.0. Snow load calculator for planning pounds from roof area and a stated ground snow load. Waste, rounding and the rate you type stay on the sheet so a quote letter can still explain the number. Add the line to an estimate. Planning takeoff only — not a code approval and not a live supplier price.
- Formula ROOF-SNOW-001 version 1.0.0 is the arithmetic on this snow load calculator page and on the quote letter.
- Roofing takeoff: Planning snow load in pounds from roof area and a stated ground snow load. Not a PE stamp. Waste and purchase rounding stay visible inputs, not hidden constants.
- Add the snow load calculator result to an estimate, then send a quote letter — an old letter still explains itself.
- You type the unit rate. Construclytic does not fetch supplier prices for this roofing tool.
- Planning takeoff only. The snow load calculator is not a code approval, mix design, or PE stamp.

Planning load in pounds is horizontal roof area times the stated ground snow load in psf. Not a balanced-design, drift or PE calculation.
ROOF-SNOW-001 is planning pounds: horizontal roof area × the stated ground snow load. It is not ASCE 7, not a drift analysis, not a PE stamp and not a rafter size. Qatar work should leave this at a spec value of zero unless a stated load exists.
Worked example. Example: a 40 × 30 ft roof at 30 psf is 36,000 lb, or 36 kips of planning load.
- 1. Use the horizontal footprint, not the sloped area, unless your spec says otherwise.
- 2. Enter the map or spec value you were given. Do not invent a climate number.
- 3. Carry the pounds into a conversation with the designer. This page does not size rafters.
Field notes that change the number
- Use the horizontal footprint, not the sloped area, unless your spec says otherwise.
- Enter the map or spec value you were given. Do not invent a climate number.
- Carry the pounds into a conversation with the designer.
Common mistakes
- Treating this as a balanced-design or PE calculation.
- Using sloped area when the spec is ground snow on the horizontal.
- Sizing rafters from this number.

Questions
Questions about snow load
Is this ASCE 7?
No. Importance factors, exposure, thermal factors and drift are not in this arithmetic.
Ground or roof snow?
The input is labelled ground snow load. Roof snow is a designed reduction the PE owns.
What is the formula ID?
This snow load calculator publishes formula ROOF-SNOW-001, version 1.0.0. The ID stays on the result and on the estimate line.
Is this engineering advice?
No. The snow load calculator is a planning takeoff. Construclytic is not a registered engineering or contracting firm. Field checks, codes and product data still sit with you.
Does Construclytic fetch live supplier prices?
No. Costs on the snow load calculator use the rate you enter. Construclytic does not fetch live supplier prices.
