The term roof pitch refers to the slope or angle of your roof. This measurement tells you how steep your roof is, and it’s essential to helping your roofing company determine what type of materials will work best to keep your home protected. Roof pitch is measured by taking the vertical rise and measuring it by the horizontal run. Pitches can vary based on location and the type of building or home you have. Roof pitch is important because it helps to ensure that rain and snow properly drain to prevent rotting and decay.
Pitches and Categories
A flat roof basically has no pitch and is commonly seen in the Southwest as well as on commercial buildings. Even though it’s called a “flat roof,” it still has to be able to drain water to prevent rot and mold buildup. Because of this, flat roofs use the smallest rise which is ¼ inch per 12-inch slope, giving it a two-percent grade for draining. Any other roof will have a more significant pitch, but it will vary based on many factors. Some of these factors include the size of the home, where the home is located, and the builder’s preference.
Roof Pitch Facts
As a homeowner, you should know a few things about roof pitches. Here are a few helpful facts so you can better understand the importance of this measurement:
- Manufactures of roofing systems mark the range of pitch that is suitable for specific materials. The roofer must use a system that is compatible with the building’s pitch in order to avoid water damage and to ensure the warranty is valid.
- Roofs with a steeper slope tend to last longer since water and other precipitation runs off the surface much quicker. Steep slopes also don’t directly absorb UV rays. The downside to these roofs is that they require more building materials including framing and shingles, which can increase the cost.
- Flat or low-sloping roofs are growing in popularity. This is mainly due to new products used that can increase energy efficiency and help with moisture protection.
- While every situation is different, many roofing products today are not designed to be installed on slopes lower than 3:12. This includes material like tile or composition shingles. These materials need a steeper slope pitch to ensure they can shed water effectively, minimizing possible roof damage.
