Best Roof Angle For Snow

There are advantages and disadvantages to having a steep pitch versus a shallow or low pitch the most obvious of which is the roof s ability to shed or withstand heavy snow rain or wind.

Best roof angle for snow.

Use a handy tool like snow load calculator to help you determine if your roof can handle the weight of snow based on its pitch. Across all materials this threshold is around 45 50 degrees away from perpendicular. The safest way to determine the pitch of an existing roof is to measure from inside your attic using a level tape measure and pencil. Significant here means less than an 8 change.

These are also the most common pitches for shed roofs. The pitch of the roof is determined by the vertical rise in inches for every horizontal twelve inch length. A flat roof would have a 2 12 pitch while the average roof pitch would be between 4 12 and 9 12. Flat and nearly flat roofs a pitch of 1 in 12 or 2 in 12 cannot be covered with shingles or shakes of any material since there is not enough angle to combat the danger of blow off.

Because it is one of the many key elements that determine the safety of the roof over your head there is a very good reason to understand the purpose of roof pitch. To put this another way you can tilt a roof angle about 45 degrees away from the optimal angle the perpendicular angle to the sun without significantly affecting light transmission. Again the most important consideration is the weather. Simply put roof pitch is the measurement of the angle or the steepness of your roof.

At these slopes snow creeps rather than slides and is easy to manage. Basically the steeper the pitch the better it can shed snow and rain. On roof slopes between 4 12 and 6 12 rough textured roofing materials work best. How roof pitch determines suitable roofing systems.

A reputable roofing contractor will be familiar with the pitch required by these codes. This image shows a relatively shallow roof pitch of 15 degrees. Pitch is a measure of the steepness of a roof. This will extend the life of your roof.

If you are building a new roof however consider the climate to determine the correct pitch and proper materials. Any roof from 4 12 to 9 12 is considered an ordinary angle for a roof. Having a steeper pitched roof allows for more space in a shed loft. The loft space would be much larger with a roof pitch of 45 degrees.
