Different Parts of a Roof and Their Functions 

Different Parts of A Roof

While learning about the roof components, it is also essential to know that roofs are different, and the roof types depend on the house’s structure. However, you are likely to find most of the roof parts in our list, if not all. Take a look!


A truss is like the skeleton of the roof. This part has many pieces like the rafters and ridge rafters. A truss is also the pillar to the covering, underlayment, sheathing, and insulation, and all the other elements the homeowner will want to put under their roof. 


The covering is the shelter of the house. It prevents elements like rain, sun, wind, and snow from getting into the house. It also prevents the entry of animal droppings and dust. There are many types, and you choose according to your preference. 


Rafters are installed under the covering to support it and also to support insulation materials. Rafters run from one end of the roof to the other. Most of them are wooden, and there are also metal rafters. 


The fascia runs across the roof’s edges, and it is primarily wooden. It also supports the gutters, and roofers nail it on the rafters. Besides its protection role, fascia also enhances the house’s curb appeal, so you should consider buying attractive ones. 


Not all roofs have ridges. You will find a ridge on pitched, gambrel, and gable roofs, among other types. They have the shape of an inverted V and connect the two parts of the roof at the top to prevent leaks. 

Ridge tile

The roofer places tiles or other materials on the ridge to cover it. The role of a ridge tile role is to prevent the entry of dust, debris, and water leakage into the roof. The ridge tiles match the type and material of the ridge. This part of the roof is not on flat roofs. 


Pitched, mansard, gambrel roofs, among other types, have eaves, which makes the lowest side of a roof. These are the parts where you connect the gutters and where water is falling from the top. 


Valleys are where the pitched or sloped roofs meet, and they make a right-angled shape. As a result, you will see a valley rafter underneath the valley. To enable water to run down the valley rafter to the gutter, install a shallow gutter-like piece. 

Ceiling Ties

Ceiling ties mainly give more strength to the rafters. They are mostly wooden, and they are placed along the rafters. The ceiling ties also make work more manageable when the roofer is attaching the soffits.


When you look up straight to the roof, you will see the soffits. Roofers place them between the wall and fascia and rafters and ceiling ties. 


During the roof construction, the roofer will install sheathings over the rafters. Their role is to strengthen the roof. They also give more support to the underlayment and insulation. 


Underlayment is mainly insulating materials that the roofer installs under the sheathing. Most of them are bituminous products and felt, and they improve on waterproofing. 


Shingles are essential parts of a roof system because they offer the first protection of weather elements to the house. There are many types of shingles, including metal sheets. When selecting, buy water-resistant shingles with good color for aesthetics. 


Not all houses have skylights because it is a luxury feature. This roof part acts as a window to allow in light and for ventilation. If you want your home to have skylights, ensure you get a qualified installer because these can be a reason for leaks. 


Roof insulations are common, but you might not notice them because the insulation is underneath the shingles. There are many types of insulation. Without it, the house will attract a lot of heat or become too cold in winter.
