Here’s a comprehensive guide of terms you should know to talk to a roofer in Simi Valley. After reading this article, you’ll ease communication barriers when planning roof repair in Simi Valley and feel more confident with negotiating prices and asking questions.


Roof decking is the foundation for a roof made of concrete, wood, steel, or other materials. It’s what covers the space between trusses and the joints of your roof.

During an inspection, Simi Valley roofers look for Buckling shingles, holes, mold, or mildew, as these concerns are the telltale signs of decking damage.

Drip Edge

A drip edge is what sits at the edge of your roofing in the form of an L shape to direct rainwater away from the fascia. Your drip edge also helps to protect the underlying components of your roofing. Rust is the main indication for needing a drip edge replacement.


Fascia is a horizontal wooden board that is attached to the edge of your roof, separate from the drip edge. The fascia provides attachment points for your gutters and drainpipes, giving your roofing a clean finish. Peeling paint is something our Simi Valley roofing crew looks for as an indicator of damage.


Flashing is the term used for a sheet of galvanized steel or other materials that directs rainwater and runoff away from the vital parts of your roofing. It helps to prevent leakages where your roof meets a vertical surface. Installation is most common near chimneys and ventilation. The darkening or bending of shingles shows signs of damage.

Frieze Board

Sitting at the top of a home’s siding, a frieze board creates the transition between the soffit and the siding or two different sidings. With the soffit, it forms a corner under the eaves.


Gable is a common term that refers to decoration that connects roofing that slopes in opposite directions. It forms a triangle at the top of a home’s sidewall, joining at the roof’s ridge.


The hip is the side connection between two separate roofing slopes, running from the ridge to the eaves. They are usually protected by additional shingles.


The ridge is the horizontal line that runs across the entire top of the roof, where two planes meet. This meeting point also forms the peak.


The soffit is the decorative underside of an eave, giving it a finished appearance. It protects the rafters from weathering but can also suffer damage from it. Roofers of Simi Valley suggest regular inspection and replacement to prevent them from crumbling.


Trusses support the rafters of your home. Once trusses are in place, homeowners should never alter them as they bear most of the roof’s weight.


The valley refers to the slopes of the roof met to form a V-shaped angle, which allows for water runoff, and they usually consist of fiberglass or concrete.

Bottom Line

There you have it; those are just some commonly used workplace terms that you can easily wrap your head around. Keep these in mind, and you’ll be talking like a roofer in Simi Valley in no time.
