Rockland County Roofing: Article About Roof Slope
The slope of a roof, also known as its pitch, is important for determining what kind of roofing material to use, how to perform repairs and maintenance, and what kinds of roofing problems are most likely to occur. Rockland County roofing professionals believe that property owners should know the basics about roof pitch in order to make informed decisions about their roofs.
The pitch of a roof is measured as a ratio of the number of inches a roof's surface rises vertically for each measure of distance that it runs horizontally. Pitch is most commonly expressed as the distance raised per 12 inches of horizontal distance. For example, a roof with a rise of six inches for each run of 12 inches would be noted as having a slope of 6:12. The pitch or slope of a roof may also be given as an angle, such as a 30-degree slope.
Generally, a slope with a pitch less than 2:12 or 10 degrees is considered a flat roof. Flat roofs are easier and safer to maintain because slips and falls are less likely on an even surface.

Many homeowners and other property owners prefer a flat roof because it makes it possible for them to use the roof for things like stargazing or rooftop lounging.
However, flat roofs are more prone to ponding than their counterparts with a more significant slope because it can be difficult for water to drain. They're less common in climates where there's a considerable amount of rain or snow, both of which can accumulate and add weight and moisture to the roof. Property owners should also be aware that foot traffic on a roof, whether flat or sloped, can cause damage to the roofing material and lead to leaks.
Roofs with a slope greater than 2:12 or 10 degrees are considered sloped roofs. They're preferred in areas with high precipitation. The higher the slope of the roof, the less likely it is that water, snow, or other debris will be able to accumulate. However, a slope is also associated with difficulty in maintenance and repair. These dangers are obvious on roofs with very steep pitches, but the incidence of roof falls and other accidents is doubled at a roof slope as low as 4:12.
Knowing the slope of a roof will help both the property owner and any professional contractors properly and safely prepare for any maintenance or repair project, and it can also help property owners determine the best maintenance routine for their roof.
