What Is the Difference Between Soffits and Fascias?
When all you need your roof to do is keep out the rain, wind and cold, you probably think of it as a single item. You’re not interested in the various parts, let alone what they’re called. There are a bewildering array of roof elements, however, with even more bewildering names.
Among the strangest of these are the fascias and the soffits. Although these might seem rather obscure, they’re essential for your roof to do its job. So what exactly are they — and what’s the difference between them?
What Is a Fascia and What Is It For?
Although the term “fascia” has various meanings in classical architecture, in the context of a modern home it forms part of your roof’s eaves. The eaves are the overhang, which has the function of directing water away from the joints where the roof meets the wall.
This involves the rafters, known as lookout rafters, that extend out beyond the walls in order to support the eaves. The fascia is a vertical band that protects and seals in the rafters, preventing them from becoming damp and developing rot. That could put your entire roof at risk and might mean having it replaced.
The fascia also adds extra support to the tiles and the guttering. Traditionally, it’s been made of wood, though non-corrosive metal can also be used. However, the ideal modern material is uPVC, which is both light and very resistant to the effects of the weather. It’s also relatively low-cost to replace.
What Is a Soffit and What Is It For?
Meaning something fixed beneath, the term “soffit” can refer in architecture to the underside of anything from an arch to a staircase. Most commonly, however, it means the underside of the eaves — a horizontal board connecting either the fascia or the edge of the roof to the wall.
Made from the same range of materials as the fascia, the soffit also protects the lookout rafters from dampness. In addition, however, the soffit plays a vital role in ventilating the roof space, allowing cool air to flow in and prevent condensation.
Why Is It Important to Maintain Fascias and Soffits?
Fascias and soffits both support and protect the eaves of the roof, and damage will prevent them from doing so effectively. As already mentioned, this could result in rot and mould developing in the rafters, compromising the whole roof structure. The fascia also supports the guttering, and damage could lead this to collapse.
Besides practical issues, fascias and soffits both contribute to your home’s kerb appeal. Both are in full view from the ground, and whether they’re plain or ornate, they can enhance the building’s look. Conversely, any damage will be very obvious to a viewer.
This makes it essential that your soffits and fascias are inspected regularly and repaired as soon as any issues arise. Give Empire a call to find out how we can ensure your eaves remain sound and attractive.
