Your residential roofing in Vancouver is made up of a lot of parts. Here, we’re only going to discuss three: (1) the soffit, (2) the fascia, and (3) the underlayment. Each has its own special function and aesthetic purpose.
The Soffit
The word soffit comes from a Latin word that means “to fix underneath” and a French word that means “formed as a ceiling.” The soffit can be found on the eaves of the roof, the part that you see underneath the exposed hanging section. The term may also refer to the horizontal part that faces the ground of a staircase, an archway, or a ceiling. The soffit functions as part of the ventilation system as this is where the air vents are usually placed.
The Fascia
The fascia refers to the horizontal board that is perpendicular to the soffit. You can find this in between the gutter attachment and the edge of the roof.
The fascia functions as a protective layer against probable weather- and water-induced damage to the wooden boards behind it. Because of this, the fascia requires regular inspection. The fascia also serves an aesthetic function as it provides your exterior with a sleeker, smoother appearance.
The Underlayment
In terms of function, the underlayment serves as the second layer of defense against the forces of nature. Whenever there’s a storm and it’s stronger than what your roof panels can handle, the underlayment comes into play, directing water and moisture back to the roof exterior before it reaches deeper levels of the roofing system.
It’s good to know the basic parts of your roofing system. If you think you need more information regarding your roof or if you’re in need of roof repair in Vancouver, don’t hesitate to give us at Crown Roofing LTD a call, and we’ll be more than happy to help.
