When you’re planning a roofing project, it’s common to hear terms that may seem unfamiliar. TBAR Roofing understands that roofing terminology can be confusing. Our roofing glossary is designed to help homeowners and professionals alike better understand the common terms you’ll come across during a roofing project.
ASTM International
ASTM International is an organization that develops standards for materials, products, systems, and services. Roofing materials that meet ASTM standards are tested for durability and reliability. This makes sure that products perform as expected in various conditions.
Asphalt Roofing Cement
Asphalt roofing cement is a thick, sticky substance used to bond roofing materials together. It is often used to seal flashing, joints, and seams to prevent leaks.
Architectural Shingles
Architectural shingles, also called laminated shingles, are multi-layered roofing materials that add depth and visual appeal to a roof.
Blistering
Blistering is when bubbles or raised areas form on the surface of asphalt shingles. This usually happens when moisture becomes trapped under the shingles during installation. Over time, blisters can weaken the roof and lead to premature wear, so it’s important to address them quickly.
Concealed Nail Method
In the concealed nail method, roofing nails are driven into the underlying layer of roofing material and hidden beneath the overlapping shingles. This technique is commonly used in roll roofing systems and helps reduce the risk of leaks.
Decking
Decking refers to the foundation of the roof, usually made from plywood or OSB (oriented strand board). It is the surface to which the roofing materials are applied.
Eaves
Eaves are the edges of the roof that extend beyond the walls of the house. They help direct rainwater away from the foundation and prevent water from dripping onto the exterior walls.
Flashing
Flashing is a material used to seal joints and seams in the roofing system, such as around chimneys, vents, and skylights. It is typically made from metal or rubber and prevents water from seeping into vulnerable areas.
Granules
Granules are small, colored particles applied to the surface of asphalt shingles to protect them from UV rays and weathering. They also give shingles their color and texture. Over time, granules may wear off, especially in areas with heavy foot traffic or intense weather conditions.
Interlayment
Interlayment is a layer of material, usually underlayment, placed between roofing layers. It acts as a moisture barrier and brings an extra layer of protection against water infiltration.
Overhang
The overhang is the part of the roof that extends beyond the exterior walls of the home. It helps protect the walls from water damage by directing rainwater away from the building. Properly sized overhangs can also improve the home’s energy efficiency by reducing heat gain during the summer months.
Ridge
The ridge is the highest point of the roof, where two slopes meet. This area is often fitted with ridge caps to protect the roof from leaks and provide ventilation. Proper ridge installation makes sure that water does not seep into the home through the top of the roof.
Ridge Vent
A ridge vent is installed along the ridge of the roof to allow hot air and moisture to escape from the attic. This helps improve ventilation and reduces the risk of heat buildup. It can lead to premature wear on roofing materials.
Roof Deck
The roof deck is the surface to which the roofing materials are attached. It is usually made from plywood or OSB and delivers the structural support for the entire roof. A strong, well-maintained roof deck is important for the stability and longevity of the roof.
Shingle
A shingle is a roofing material, typically made of asphalt, wood, or slate, that is used to cover the surface of the roof. Shingles are installed in overlapping rows to create a watertight barrier that protects the structure beneath.
Underlayment
Underlayment is a layer of material, typically felt or synthetic, that is installed between the roof deck and shingles. It provides an additional layer of waterproofing and prevents leaks and damage to the roof deck.
Valley
A valley is the area where two roof slopes meet, typically at an angle. Valleys are important for directing rainwater off the roof. Special flashing is used in the valley to prevent leaks and guarantee proper water flow.
Vent Pipe
A vent pipe is a pipe that extends through the roof and allows air to circulate in the plumbing system. It prevents the buildup of harmful gases and guarantees the proper flow of wastewater.
