Which Are the Essential Parts of a Roof?

The roof is a crucial component of any building, whether commercial or residential. However, did you know that the roof is made up of different parts? All these parts play different roles, but they are all geared towards ensuring that the roofing system functions effectively. Every building needs a touch from IKO roofing professionals and other experts to ensure that its roof is well done.

The Parts

The following are some of the roofing components you should keep an eye on;

The Covering

This part has two significant functions: protecting your roofing system from the elements and adding style and design to the building. Different roofs have varying covering materials, including IKO shingles, metal, wood, and tile.


Water accumulation can be detrimental to the condition of your home’s roofing system. That is why a channel is needed to direct rainwater and melted snow away from the roof. This is the primary function of roof gutters, which run around the roof’s edge. Regular maintenance is required to ensure that debris does not accumulate on the gutters, leading to clogging of the roofing system and overflows. Most gutters are made from plastic and other water-resistant materials. Gutters work harmoniously with downspouts – the pipes running down from the roof that direct water and melted snow to a designated outflow point. With that, you can be sure that the sides of your home are protected against water damage.


As the name suggests, this integral component is installed under the covering and right on top of the roof decking. The main function of this thin black paper is to inhibit the intrusion of water, air, and other elements onto your roof in case they manage to pass through the shingles. However, experts advise you to have an extra waterproof membrane or vapor barrier installed to help the underlayment function better and boost the roof’s lifespan.


The roof also needs to breathe like any other part of a building. The ventilation function is to minimize humidity and condensation build-up in your attic. Moreover, a functional ventilation system helps your home achieve energy efficiency by reducing the load on your AC and HVAC systems.

Every building requires a roof to protect its interior and the occupants from the elements, such as wind, rain, sun, and snow. However, it is vital to understand the different roof components and how each one functions, as discussed above.
