Protecting your British Columbia home from the elements is the #1 job of your roof. It’s a complex system of interlocking components that must all work together to create a powerful barrier against rain, snow, ice and wind. At Crown Residential Roofing, we treat your roof as a complete system, from the bare decking up to the ridge ventilation – even the gutters! Knowing about these and other important components of a roof will allow you to better understand your project and what to expect of your roofing contractor in Vancouver.
• Decking (also known as sheathing). Made from wood material such as plywood or OSB, decking covers the rafters and acts as the base for roof coverings. Only seasoned wood can be used for decking, otherwise the result will be a warped, buckled roof base.
• 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 home is under construction, the underlayment acts as protection against the elements while shingles are installed.
• 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.
• 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. Vented roof caps are often installed along the length of a ridge to allow hot air to escape from the attic and improve ventilation.
• Gutter. The trough running along the eaves of a roof that channels water to the downspouts.
