10. Plastic guttering

Commonly made from vinyl or PVC, plastic gutters offer an affordable and light alternative to metal systems. While not as durable as some other materials, plastic gutters are resistant to corrosion and rust.

Best applications: Plastic gutters are popular choices for residential properties and outdoor shed structures. They are easy to install and require minimal maintenance compared to metal options. However, plastic may not be suitable for harsh climates and may need frequent replacement or guttering repairs.

Average lifespan: Vinyl (10-20 years); PVC (20-30 years). 

What is the difference between soffits and fascias?

While soffits, fascias and guttering are all critical components, they have different functions. It is essential to understand the roles of each element to ensure proper installation, maintenance and overall protection.

Fascias

Fascias are long, straight boards that run horizontally along the lower edge of the roof line. They serve as decorative trim and a structural component, offering a solid surface for attaching gutters and other roof accessories. Fascias are typically made of wood, vinyl, aluminium or fibre cement. They can be painted or finished to complement the appearance of a property. 

Soffits

Soffits are the underside of the overhanging portion of the roof, covering the area between the fascia and the side of a building. They play a crucial role in ventilation, allowing air to flow into a loft space while preventing moisture buildup. Soffits are commonly made of vinyl, aluminium or fibre cement. They can be vented or non-vented depending on the ventilation requirements.
