The roof is, without doubt, the most important roof components of any building, as it protects against the harsh elements. There are many smaller components that go to make up a roof, and each has its own role to play.

Here is a list of roofing components, along with the specific role that each has. 

Decking or Sheathing

This is usually made from plywood and it seals the roof, while also providing a nail bed for the batons that the roof tiles are fixed to, added plywood experts from Cut My Plastic. The decking would be treated to preserve the wood and usually sealed at the edges with silicone. There is also an online list of common roofing issues, along with suggested repairs, which is recommended reading for any new homeowner.

The Ridge

This is the top edge of a pitched roof and special tiles are installed that prevent water from entering the roof. This is usually the last line of roofing tiles that are installed. With Sydney based roofing specialists, you can be sure of a first-class installation. Typically, the ridge tiles are sealed with silicone for added waterproofing, then they are fixed with nails to the plywood membrane under the tile layer.

Fascia & Soffit Boards

These are fixed to the bottom line of roof tiles and protect the underside of the roofline. The fascia is visible from the front, while the soffit boards are attached to the underside of the eaves. Many Australian homeowners prefer to use PVC sections rather than timber, as they do not require maintenance.


Typically made from lead, galvanized steel, or copper, the flashing protects the joints, providing a waterproof covering that ensures no rainwater can enter the internal roof structure. Installing flashing is a skilled art, and the flashing can provide a visually appealing contrast to the roofing tiles.

Shingles or Roof Tiles

There are a variety of materials used for roof tiles, and the slate is regarded as the best material, thanks to its classic look and durability. A slate roof will cost you more than one with regular clay or asphalt tiles, yet it does make for a wise long-term solution, which is why so many homeowners have chosen a slate roof.

Guttering & Downpipes

These are essential components that provide an escape route for excess rainwater and can be made from stainless steel or PVC, which is a popular choice, as it requires no maintenance. Guttering should be shallow but wide, which can handle heavy downpours and it should be cleaned out on a regular basis to prevent blockages. This is why it is always recommended to install Stainless Steel Gutters for your home.

Various Roof Components

If you are planning a new build, it makes sense to fully consider all of your options, which include slate, regular roof tiles, and even metal, which is also a popular choice among many homeowners, thanks to its durability. An online search will help you locate local roofing contractors. By asking several to quote for the project, you will gain a better understanding of what is available, and you can compare prices too. One thing you do want is a roof that will stand the test of time, and any reputable roofer would issue you with at least a15-year warranty on a new roof, which gives you peace of mind.
