When most people think “roof,” they’re thinking of a certain roofing material: shingles, tile and so on. In reality, a roof is much more than a layer of colored shingles. It’s an integrated system composed of several parts, each with an important function that contributes to the overall longevity and performance of your roof.
A roof is only as good as its weakest leak! Here are the most crucial parts of a Burnaby roofing system:
1. Roof deck. Decking serves as the foundation for all other roof components, and is typically made by nailing plywood or OSB to the rafters. Only seasoned wood can be used for decking, or the result could be a warped, buckled roof base.
2. Underlayment. A layer of roofing underlayment, most commonly black felt paper, is used on pitched roofs as a secondary layer of protection for the roof in case water penetrates the shingles. When a building is under construction, the underlayment also acts as protection against the elements while shingles are installed.
3. 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 provide protection from sun, wind, moisture, impact and fire, and come in a wide variety of colors to complement a home’s exterior.
4. Flashing. Flashing protects the most vulnerable areas of a roof from leakage, such as around exhaust vents, pipes, chimneys, dormers and skylights, and along valleys. Flashing is made from a number of materials, the most common being galvanized metal.
