This week we’re going to take a look at the major components of your British Columbia roof. It’s been our experience that clients who know some basic terminology can better understand their project and what to expect of their Vancouver roofing contractor.
Ridge. The ridge runs along the top of the roof where two sides meet to form an angle. The ridge must be shingled or capped to prevent water leakage into the attic.
Flashing. Flashing protects vulnerable areas of a roof from leakage, such as around chimneys, dormers and skylights, or where there is heavy water runoff. Flashing is made from a number of materials, the most common being galvanized metal.
Underlayment. Rolls of roofing underlayment, most commonly black felt paper, are used on pitched roofs as a secondary layer of protection for the roof. When a building is under construction, the underlayment acts as protection against the elements while shingles are installed. While felt paper is the most commonly used underlayment today, a wise Richmond roofing contractor will opt for synthetic underlayments or self-adhering underlayments to combat excessive moisture.
Sheathing (also known as decking). Made from wood material such as plywood or OSB, sheathing covers the rafters and acts as the base for roof coverings. Only seasoned wood can be used for sheathing, otherwise the result will be a warped, buckled roof base.
Shingles. Used on the majority of homes in North America, shingles are made from an asphalt-saturated base that is then coated with minerals to resist weathering. They come in a wide variety of colors to complement a home’s exterior.
