Pitched roof construction

When we talk about roof construction, we usually talk about pitched roofs. The other type of the structure is the flat roof, which has only a small angle in comparison to the pitched ones. Now we could talk about the design, but we will leave that for another time. We want to speak of the construction of the said type of roof and to mention all the important aspects of roofing.

Roof frame and details

A standard roof usually has trussed or cut construction. In some cases, the builders use the combination of both to create complex roof designs. In any case, the primary purpose of both of these is to support and cover the structure. Both of these will support conventional roofing materials (check which types of material you can use for roofing).

The cut roof design is the original and companies used it long before the introduction of trussed frame. It’s quite labor-intensive as it requires on-site cutting and it won’t be able to support the full weight of the construction without the use of purlins. They are used to transfer the weight of the frame to the loadbearing walls.

Common trussed frame design is also known as the A-frame due to its shape. It combines joists, jacks, and rafters to create a robust construction that can carry the weight of the roof. Several of these support the whole roof, no matter what type of material is on them. The advancement of the technology allowed for the creation of lighter A-frames that can support the full weight of the roofing construction.

Many companies build these frames on site, which is something we avoid. We make them in our buildings as soon as we gain all the parameters.

Other types of roof frame

Those two frame types aren’t the only option for a homeowner; there are other styles of the ceiling they can opt for. People whose houses have wide span (above 54 feet) can opt for Triple Howe, which is a perfect frame style for large buildings. Then there is the room-in-attic option which leaves enough space under the frame for a small room.
