As a homeowner, it's important to understand the terminology used in the roofing industry. Knowing these terms will help you communicate with contractors, understand roofing warranties, and make informed decisions about your roof. Here are some common terms and phrases you should know:
Pitch: The pitch of a roof is the slope or angle of the roof. It is usually expressed as a ratio of the rise (height) to the run (distance). For example, a roof with a pitch of 4:12 means that for every 12 feet of horizontal distance, the roof rises 4 feet.
Underlayment: The underlayment is a layer of material, usually felt or synthetic, that is installed under the roofing material. Its purpose is to provide an additional layer of protection against water and to help prevent leaks.
Flashing: Flashing is a material, usually metal, that is used to cover and seal joints and transitions in the roof. It is commonly found around chimneys, vents, and skylights.
Ventilation: Roof ventilation refers to the circulation of air through the attic or roof space. Proper ventilation is important to prevent moisture buildup, which can cause damage to the roof and lead to mold and mildew growth.
Ridge: The ridge is the highest point on the roof where two roof surfaces meet. It is usually covered with ridge shingles or a ridge vent.
Ice dam: An ice dam is a ridge of ice that forms at the edge of a roof and prevents melting snow from draining off the roof. Ice dams can cause water to back up under the roofing material and leak into the home.
Drip edge: A drip edge is a metal strip that is installed along the edges of the roof to direct water away from the fascia and into the gutters.
By familiarizing yourself with these common roofing terms, you'll be better equipped to communicate with contractors, understand warranties, and make informed decisions about your roof. If you have any questions or concerns about your roof, don't hesitate to contact a roofing professional for help.
