Five Common Roofing Terms You Need To Know
Whether the home you have just purchased is brand new or vintage, there will undoubtably come a time when you need to hire a roofing contractor to repair or replace your roof. Becoming familiar with terminology frequently used in the roofing industry will help you to be better able to communicate with your roofing contractor when the time comes. Following are five roofing terms that all homeowners should be familiar with.
Proper drainage is extremely important on roofs because without it, water may build up and pool, causing mold and mildew infestation, rotting underlying wood, and eventually resulting in enough structural damage to cause leaks. The term roof drainage is used to refer to the features that allow for efficient flow of water off of the roof's surface. The slope of the roof, for instance, is a part of the overall drainage strategy and is why you will see steeply sloped roofs on homes located in areas that receive a great deal of snow during winter. Roof drains are typically installed by roofing contractors rather than plumbers.
Roof covering refers to the materials used to cover the surface of your roof. This could be anything from asphalt shingles, ceramic tiles, cedar or other wooden shakes, slate or other stone shingles, metal shingles, or lightweight, inexpensive roll roofing.
Also referred to as tar paper or underlayment, felt is a fibrous material that is placed under the covering and is designed to provide a water-resistant layer underneath the shingles. Felt also provides a nonslip working environment for roofers while they are installing the covering.
Flashing refers to the material that facilitates the flow of water off the surface of your roof. Properly installed flashing is an essential component of reducing water damage to your roof. Flashing is usually made of sheet metal, copper, stainless steel, or composite materials, but PVC-based plastic flashing is being increasingly used -- however, exposure to UV rays may cause premature erosion in this type of flashing if parts are exposed.
Sheathing Also referred to as a deck, sheathing is a layer of wood or other fibrous materials that serves as a base for your roof. It is secured to the rafters and strengthens the overall structure. It is essential that sheathing is properly spaced in order to account for the expansion and contraction of the materials caused by changes in temperatures throughout the season.
