What Makes Up a Roof – Your Roof Components

The roof of your house is made up of more than just asphalt shingles. Your home is protected from fog, wind, and snow by a system of roof elements. To describe an issue to a roofing contractor to consider what he or she is concerned about while making maintenance, it is important to understand all of the components of a house roof.

Here’s a list of all the Roofing terms we’ll discuss in this article:

What are the Parts of a Roof Called?

Attic

The area under the roof. To protect the roofing system from extreme heat in the summer and warm moist air produced by the house in the winter, the attic (attic space) must be ventilated. If excess humidity comes into contact with cold surfaces under the roof, it can transform into frost.

Decking

The decking, which is usually made of 1/2-inch plywood, closes and supports the roof frame while also providing a nailbed for shingles.

Ridge

At the top of the roof (roof ridge), there is a horizontal line that separates the two sloping roof planes.

Saddle

Rainwater is diverted around a chimney by a device situated behind the higher side of the chimney (or equivalent projections from the roof). This is what is known as the saddle.

Roof edge

Many of the boards that extend down the roof’s edge, or eaves. This is also commonly called “Fascia”.

Roof Valleys

The “V-cut” angle formed by the intersection of two roof slopes. Flashing, made of a lightweight fibre, metal, or, better still, a mixture of the two, is used to keep the valley watertight.

Underlay membrane

This underlayment covering, which is made of asphalt-soaked felt or synthetic fibre, prevents the shingles from resin produced by the wood decking as well as the decking from bad weather. Certain warranties need this membrane to be installed.

Eaves membrane

This protective membrane is installed under any or all of the asphalt shingles in the winter to prevent water infiltration caused by “ice dams.”

Drip edge

A drip edge is a piece of moulding that runs over the roof’s edge which prevents water from getting in.
Roofers and manufacturers recommend it, even if it isn’t needed by the Code. In the sides of the roof, it is fixed straight to the decking and runs around the bottom of the roof slope, above the underlay.

Roof vents

These sealed metal or plastic frames have openings and fins to ensure adequate ventilation of the attic room. The most efficient vents have four open sides and are elevated above the roof, allowing them to absorb wind from all directions and provide a suction effect. An air inlet at the base of the roof, via perforations in the eaves soffit, is needed for complete attic ventilation. This piece, which is usually made of perforated aluminum, seals off the underside of the eaves.

Deflector

A piece of polystyrene or cardboard is placed between 2 rafters to allow air to freely circulate over the insulation near the soffits. Under the decking, there should be at least two inches of space.

Plumbing vent

These vent pipes exit from the roof to allow air to enter the plumbing system, allowing wastewater to drain properly to the sewer or septic-system leaching area.

Flashing (joint covers)

Flashing is made of galvanized steel, titanium, or plastic and can be rigid or rigid, or more flexible.
Water streaming near roof openings is prevented from infiltrating the roof with this form of resistant molding. Valleys, the bases of chimneys, ceilings, roof vents, and plumbing vents all have flashing.

Flat roof

The roof is called flat if the angle is less than 2/12. The ventilation openings to insulated ceiling ratio should be at least 1:150 in this situation.

Shingles

Shingles, which are made of fiberglass and asphalt, shield the roof from rain and add charm to a home.

Choosing the shingles (Which Shingle is Right for you?)

Because of their low cost and ease of construction, asphalt shingles have become common in North America. Their waterproofing feature is based on gravity: nothing can penetrate as long as the water is flowing downward. CAA Quebec says that the lifespan of asphalt shingles is between 20 and 40 years.

While it is physically possible to add new shingles on old ones (for a variety of reasons, including cost savings), this is not recommended because the underlying flaws will distort the new coating sooner or later.

FAQS

What is the structure of a roof?

The roofing system (roof structures) is basically the framework upon which your roof would be built. The roof frame is made up of a set of trusses, beams, and rafters that give the roof its form and serve as the foundation for the roof sheathing. When you see timber connected on top of the main housing frame on a house under construction, you’re staring at the roof systems.

What is a four sided roof called?

A french roof, also known as a mansard roof, is a four-sided roof, that is low-pitched, with a double slip on either side. The lower slope is significantly steeper than the higher one. Depending on the style, the sides may be either smooth or curved. A french roof, also known as a mansard roof, is a four-sided roof, that is low-pitched, with a double slip on either side.
