Sheathing (AKA Decking)
The sheathing is typically made from thin plywood. It is meant to reinforce the structure and be a suitable nailbed.
Underlay membranes a blend of felt with either synthetic fabrics or asphalt. The underlay membrane is put in place to protect the shingles from the decking and the decking itself.
Shingles are typically made with fiberglass and asphalt. They protect the roof from outside elements.
Roof Edge (AKA Eaves Edge)
The roof’s edge is the boards that lay along the edge of the roof.
Similar to the underlay membrane, the eaves membrane is for protection. It protects the shingles from ice dams during the winter.
The drip edge is the molding that protects the edge of the roof from water intrusion.
Roof ridges are the horizontal line along the top of a roof.
The valley is the angular cut along the joining of two slopes on the roof.
The saddle is a water diverter located along the higher side of a chimney.
Roof vents are put in place to ensure the attic area of the home is properly ventilated.
A plumbing vent is a pipe that stands straight on the roof and allows air to infiltrate the plumbing system. It helps the sewer and septic systems function appropriately.
Flashing and Valley Flashing
Typically made from galvanized steel, plastic, and aluminum flashing are the joint covers. It prevents water from infiltrating into roof openings. They are put in place around walls, vents, and chimneys.
