Terms That Roofers Use and What They Mean

Understanding the terminology that roofers use can be beneficial when discussing roofing projects, asking questions, and making informed decisions about your roof’s maintenance, repairs, or replacement. One common term that roofers often use is “flashing,” which refers to thin strips of metal or other waterproof material used to direct water away from critical areas, such as vents, chimneys, skylights, and junctions between different roof surfaces. Properly installed flashing is essential for preventing water infiltration, leaks, and water damage in vulnerable areas of your roof.

Another term you may encounter when working with roofers is “underlayment,” which is a water-resistant barrier installed directly onto the roof deck before the final roofing material, such as shingles or tiles, is applied. Underlayment serves as an additional layer of protection against water penetration, wind-driven rain, and moisture buildup, enhancing the roof’s durability, performance, and lifespan. Roofers also frequently use the term “ridge vent,” which refers to a ventilation system installed along the peak or ridge of the roof to allow hot air and moisture to escape from the attic, promoting air circulation, reducing heat buildup, and preventing moisture-related issues, such as mold and mildew growth, and premature roof deterioration.

Lastly, “pitch” is another important term that roofers use to describe the slope or steepness of a roof. The roof’s pitch affects its drainage capabilities, aesthetic appearance, and the types of roofing materials that can be used. Understanding these and other common roofing terms can help you communicate more effectively with roofers, understand the scope of work, and make informed decisions about your roofing needs and requirements.
