If you’re in the building trade, you’ll probably know what products the term roofline encompasses. If you’re more of a DIYer, you’ll be forgiven not being entirely sure. We know that sometimes there’s a bit of confusion so to clear things up, and to ensure you’re buying the correct items for the job, we’ve come up with our quick Roofline Guide…

Roofline: What’s What?

Roofline is the term used to describe the boards and accessory products that form the detailing and protection along where a roof edge meets the wall of a building. The board elements are traditionally wooden, however are now more commonly made from low maintenance PVC. These products include:

  1. Bargeboards
  2. Dry or wet verge (dry verge shown here)
  3. Guttering
  4. Fascia boards
  5. Soffit boards

1. Bargeboards

Bargeboard is the term used for a fascia board when it is fixed diagonally to the gable of a roof. The bargeboard provides strength to the roof structure, and is fixed to (and therefore conceals and protects) the roof perlins. Bargeboards are traditionally heavily decorated, however modern builds and renovations tend to prefer more understated designs.

Our fascia boards are suitable for use as bargeboards.

2. Dry Verge

The verge is a term used to describe the outer edge of the roof, above the bargeboard, where the roof tiles meet the elements. Traditionally the verge was sealed with mortar, thus preventing the elements (and bugs or small birds) from penetrating the roof; this is known as wet verge. Modern dry verge is a system of interlocking caps (usually plastic) that clip into place along the verge. Equally as effective as wet verge at keeping the roof dry and pest free, dry verge offers the added benefits of easy installation and low ongoing maintenance.

We stock a wide range of dry verge systems, ensuring you can find the type and colour that fits your job.

3. Guttering

Guttering is the term used to describe the shallow trough below the roof edge that is designed to channel rainwater flowing off the roof into the downpipes – it is probably the most well know roofline term. It is key that the correct capacity guttering is installed for the roof area, otherwise the gutters will not cope with the volume of water and will over flow. It is also important to regularly clear any debris from gutters as build-up can cause blockages and prevent efficiency. If not removed blockages can result in permanent damage.

We offer a variety of guttering and downpipe capacities to ensure all roof sizes are catered for. To prevent debris build-up, we also offer a range of leaf protection systems.

4. Fascia Boards

Fascia board is the term used to describe the horizontal board that runs along the edge of the roof and is fixed to (and therefore conceals and protects) the end of the rafters. Brackets to hold the guttering are fixed to the fascia boards. Plastic fascia boards come in a variety of thickness’s, depending on the end goal. Thinner (usually < 10mm) boards, known as cappit boards or cover boards, are designed to fit over existing or new timber fascias masking the wood beneath, providing a fresh new look. Thicker (usually < 25mm) boards, also know as full replacement boards, or full replacement fascias, are (as the name implies) designed for new builds or when the existing fascia boards will be removed.

Our range of fascia boards includes a variety of profiles (square, ogee or roundnose), as well as over 15 colours and styles. We would always recommend using full replacement fascia boards wherever possible.

5. Soffit Boards

Soffit board is the term used to describe the horizontal board that runs along the underside of the roof and is fixed to (and therefore conceals and protects) the underside of the rafter ends. Installed at 90 degrees to the fascia boards, soffit boards complete the boxing in of the rafter ends. Soffit boards can be vented or non-vented – venting provides a means of maintaining airflow around the attic space, thus keeping it cool.

Our range of soffit boards includes vented and non-vented styles, along with hollow panelled effect. As with our fascia boards, soffit boards are available in over 15 colours and styles.

6. Snow Guards

Snow guard is the term used to describe a range of products designed to hold blankets of snow in place allowing the meltwater to flow into the gutters, thus preventing damage resulting from sections of snow falling from a roof. The pictured example is a grid snow guard which provides the added benefit of also catching falling tiles. Falling snow (or tiles) can cause damage to conservatory roofs and vehicles or hurt people below.

Our galvanised grid snow guard is a cost effective way of protecting against snow and tile slippage.
