The short answer
These are the parts that make up your roofline — the edge where the roof meets the walls. The fascia is the upright board along the eaves that carries the gutter; the soffit is the board beneath it that closes the gap to the wall and holds the vents; the bargeboard is the equivalent of a fascia running up a sloping gable end; and the guttering (with its downpipes) is fixed to the fascia to carry rainwater away. Because they sit together and share access, a full roofline job usually replaces all of them as a set rather than one part in isolation.
'Roofline' is the umbrella term for all of these parts. Knowing which is which helps you read a quote and understand why installers usually price them together.

What each part is
- Fascia: the upright board running horizontally along the lower edge of the roof; the gutter bolts to it.
- Soffit: the board tucked underneath, spanning from the fascia back to the wall, usually ventilated.
- Bargeboard: the sloping board on a gable end — a fascia that follows the roof pitch rather than the level eaves.
- Guttering & downpipes: the channels and pipes that collect roof rainwater and take it to the drains, fixed to the fascia.
What gets replaced together
Because the fascia carries the gutter and the soffit sits directly beneath, they are almost always renewed together — replacing a fascia means taking the gutter off anyway, so refitting old gutter onto a new fascia is usually a false economy. A typical full roofline replacement therefore covers fascias, soffits, bargeboards, guttering and downpipes, plus any capping, ventilation and waste removal. Pricing it as one job is why combined work comes in lower per metre than doing each part on its own visit.

Frequently asked questions
What is the difference between a fascia and a bargeboard?
A fascia runs horizontally along the level eaves and carries the gutter, while a bargeboard does the same job up the sloping edge of a gable end. Both close off and protect the roof edge.
Is guttering replaced with fascias and soffits?
Usually yes. The gutter is fixed to the fascia, so replacing the fascia means removing the gutter anyway. Renewing them together in one visit is more efficient and avoids refitting old gutter to a new board.
What does a full roofline replacement include?
Typically fascias, soffits, bargeboards, guttering and downpipes, plus capping, ventilation and waste removal — all priced as one job because they share the same access.
