What Are Eaves, Flashing & Other Words On Your Roof Estimate?

Roofs are one of those things most people just don’t think about, until there is a problem. As a result, most homeowners often don’t fully understand the estimates roof contractors hand them, leaving them open to unscrupulous people who may take advantage of this.

Obviously we can’t turn you into an expert by the end of this post but even learning just a few of the major materials used for your roof are can assist you greatly in understanding a roof estimate better when it’s time.

The following are a few of the more major materials and terms to know in order to help you understand the different components of your roof and some of the services roofing contractors may offer when they give you an estimate:


Most people know what roof shingles are. They are the individual, overlapping, typically rectangle elements that cover most residential roofs from the bottom edge and up. They are made from various materials such as slate, asphalt-saturated mat covered with aggregate (asphalt shingles), wood and sometimes even concrete or clay. Available in a variety of colors and styles, these are what most typical residential roofs in Metro Atlanta consist of.

Leak Barriers

Leak barriers are watertight seals we place on the most vulnerable areas of your roof typically around valleys, eaves, vent pipes, chimneys, flashing, and other areas. Basically any area more prone to leaks.

Roof Deck

The roof deck is the surface of your roof, below the shingles and underlayment, (usually plywood or oriented strand board (OSB)) to which roofing materials are applied.

Roof deck protection is basically referring to using materials such as a fiberglass felt or a synthetic underlayment to add an additional layer of protection between the shingles and roof deck preventing damage from rain, ice, wind and/or moisture build up.

Attic Ventilation

Attic ventilation refers to how well air and moisture is circulating in your attic and is one of the most important aspects of a roofing system. Proper attic ventilation should keep air circulating throughout the attic year around, preventing moisture build-up and reducing energy costs. Symptoms of poor attic ventilation include moisture buildup in the home and/or attic sometimes mimicking a roof leak!


Basically the horizontal lowest edge of sloped roofs, usually where gutters are installed.


Flashing is a weatherproofing component of roofs. Primarily comprised of sheet metal, flashing is installed along areas prone to leakage such as around breaks in a shingled roof-line or around chimneys (stepflashing), skylights, or other areas. Installed properly, they shouldn’t be seen and will seal exposed areas preventing moisture from entering your home.

Soffit & Fascia

The fascia is the roofline, or the board that spans the area where the outer walls of the home meet the roof. The soffit is the material that covers the eaves.

These help protect your home against a variety of pests.


Asphalt-based rolled materials designed to be installed under the main roofing material for added protection.
