Roofing Components

This section is designed to help you with identifying and understanding roofing components.

Common Things seen on our quotes:

Deck Base

Deck Base: This underlayment is installed on the first 44” off your eave edge and is required by the Alberta Building Code. Deck base protects your roof deck and helps prevent water leakage due to ice dams and wind-driven rain.

Goose-neck

Goose-neck (or exhaust vent or fan vent): are for your bathroom or kitchen hood vents to exhaust unwanted air. Available in an assortment of colors to match shingles.

Maximum Air Vent

Maximum Vents: are more costly than the whirly bird but have a greater drawing power because of its design. You typically need 2 whirly birds to compare with one Maximum vent but you need certain attic conditions for this one to work efficiently. Available in an assortment of colors to match shingles.

Plumbing Jack / Stack (or pipe jack or Oatie)

Plumbing Jack / Stack (or pipe jack or oatie): Available in 2, 3 and 4”, this is a sleeve that fits around drain and waste vent pipes and are nailed to the roof sheeting. Available in an assortment of colors to match shingles.

High Profile Ridge Cap

Ridge Cap

Ridge Cap- High Profile or Regular: This is material installed over the hip or ridge of a roof. High Profile ridge cap is more bulky and provides nice detail and curb appeal for cottage style roofs. Regular ridge cap lies flat and provides and even, smooth look.

Underlayment

Underlayment: There are many types but we typically use a 7 mil synthetic fabric that gives a layer of protection between the roofing materials and the house. The right underlayment for your roof will keep moisture, cold weather and stifling summer air out. It can be left exposed for up to 6 months thus, if wind damage occurs you have that extra protection on your roof deck.

Closed Valley

Valley's

Valley’s – Open or Closed: Completely a customer’s choice. We do both and have pro’s and con’s for each method. In some situation we may suggest one over the other, which can be discussed with one of our Professional roofers. An open valley shows the metal in the valley. A closed valley has the shingles cross over through the valley.

Whirly Bird

Whirly Bird ( or Turbine vent ): is installed on a roof top to remove heat from the attic cavity. As the wind spins them, it creates a vacuum that sucks the warm air out. It’s positive ventilation and eco-friendly. This does not “ cool ” your home- it does, however, pull hot and moist air out. Available in an assortment of colors to match shingles.
