Roofline is the term used to describe the 4 combining features that make up your property's roof. These are: fascias, soffits, bargeboards, and guttering. All 4 of these additions are designed to do very different things but are equally important in protecting your home all year round.

The Roofline Model is a visual model for assessing the performance achieved by an application relative to the limits of the hardware it is running on. A basic example of the Roofline model is shown below. On the x-axis, we have arithmetic or computational intensity measured in FLOP/B.

Roofline is used to describe the fascia, soffits, bargeboards and antefixes that forms the frontage immediately below the roof and the eaves of many homes and buildings. These are traditionally made from wood, but can be made of a variety of different materials, including plastic, such as polyvinyl chloride.
