Taking the age and type of roofing material that is on your structure into consideration of course! Whether you need to discuss your current roof’s issues with a contractor or if you’re reviewing a roofing estimate, having a basic understanding of the roofing language is important. In an effort to assist you, we’ve compiled a list of common roofing terms below.

Roof Deck: the substrate that is attached to the roof framing to which roofing materials are installed

Underlayment: a water shedding membrane that is installed over the roof deck prior to installation of the roof tiles

O’Hagin Vents: generally installed near the top ridgeline of the roof, exhaust vents are designed to allow warm air to escape the attic area of the home, helping to conserve energy within the living space

Course: each row of the tile

Rake: the outer sloped edge of a roofline

Sidewall: the inner edge of the roof where the tile meets the vertical wall

Hip: the sloping ridge of a roof where two perpendicular slopes meet

Valley: the internal sloping angle of a roof where two perpendicular slopes meet

Soffit: area between the outside wall and the fascia, often enclosed and sometimes vented

Drip Edge: perimeter metal flashing, installed to protect raw edge of the roof deck

Eave Closure/Bird Stop: material used to close the convex open below the eave course of Capistrano or Malibu tiles. Prevents intrusion under the tile by birds or other wildlife and provides proper rise for the eave course.  Can be ventilated to promote air flow below the tile.

Eave Riser: material used to provide the proper rise for the eave course of tile. Usually utilized for roofs with flat tile.
