This calculator computes both the balanced and unbalanced snow loads for sloped and flat roofs. It takes into account various factors such as ground snow load, surface roughness, building importance, roof exposure, roof pitch, and the thermal condition of the building. Additionally, the calculator determines whether a rain-on-snow surcharge load is necessary. It also provides calculations for snow drift loads on lower roofs or roof projections.

Snow load calculator to asce 7-16

Calculate snow load pressures on buildings according to the American Society of Civil Engineers (ASCE) 7-16 standards.

Easy-to-use tool for roof snow load calculation

Easily input your site, building, and roof properties to get your snow load in minutes with ClearCalcs' clean and easy-to-use interface.

Automatically calculates rain-on-snow surcharge load

ClearCalcs Snow Load Calculator automatically calculates roof snow load including the rain-on-snow surcharge load where applicable by considering your roof pitch and horizontal distance from eave to ridge.

With spreadsheets and clunky software

Frustration, fuss, and fragile formulas—the old way of engineering calculations that holds you back.

Struggle with endless spreadsheets and custom formulas.

Building codes change, but outdated software and spreadsheets don’t.

Triple-check and verify manual input at every turn.

Old software feels like a maze, with unclear settings, limited templates, and rigid interfaces.

How it works

Your code-compliant calculator

Tired of complex calculations? ClearCalcs Calculator Library keeps it simple, secure, and code-compliant—so you can calculate with confidence.

Save time with ready-to-use templates for wood, steel, and concrete

ClearCalcs offers an extensive library of easy-to-use calculators for beams, columns, and footings, designed to make structural calculations simpler and faster.

Choose from a wide range of pre-configured beam and column options, complete with automatic member sizing, so you can quickly reach reliable designs and reduce rework.

Beams

Columns

Foundations

Walls

Loads

Dynamically track your load paths from roof to foundation

No need to copy and paste reactions between calculations! If the top calculator's reactions change, the loads being inherited onto the lower calculator will update automatically. This includes all loads such as dead, live, snow, seismic, and wind.

Submit professional reports for permit review

ClearCalcs is not only easy to use, but also easy to check! All calculations follow an easy to understand traffic light check system, with multiple levels of detail available giving you the choice of printing every step of the calculation and all code and standard references, or simply a compact, one-page print out.
