How to Match Fascia, Soffit & Guttering Colours
Yes, fascia and gutters should generally match — or at least coordinate — for the best visual result. The most common approach in the UK is to match the fascia and guttering in the same colour (creating a continuous dark or light frame at the roofline) while using a contrasting soffit colour underneath. In 2026, the most popular combination is anthracite grey fascia and guttering with a white soffit. The white soffit reflects light under the eaves, keeping the overhang bright, while the grey fascia and gutter define the roof edge with a modern, architectural line.
Roofline colour coordination makes a dramatic difference to kerb appeal. The fascia, soffit, and guttering frame the top of every elevation — get the colours right and the house looks polished and intentional. Get them wrong and it looks disjointed. Yet surprisingly few homeowners or installers give it the thought it deserves, often defaulting to “all white” without considering the alternatives.
The Most Popular Combinations in 2026
| Rank | Fascia | Soffit | Guttering | Style |
|---|---|---|---|---|
| 1 | Anthracite grey | White | Anthracite grey | Contemporary, modern |
| 2 | White | White | White | Classic, traditional |
| 3 | White | White | Black | Clean with definition |
| 4 | Black | White | Black | Bold, period-suitable |
| 5 | Anthracite grey | White | Black | Mixed contemporary |
| 6 | Rosewood | White | Brown | Warm, rural |
| 7 | Black | White | Black (cast-iron effect) | Heritage, conservation |
The dominance of anthracite grey reflects a broader shift in UK home design. Grey windows, grey composite doors, and grey roofline have become the go-to palette for homeowners updating 1960s–1990s housing stock. The colour ages well, hides surface grime far better than white, and gives an understated modern finish without being as stark as black.
Colour Coordination Rules
Rule 1: Match Fascia and Guttering
The fascia board and the gutter sit directly next to each other. The gutter brackets screw into the fascia, and the gutter body runs along its face. A colour mismatch here is the most visible and jarring.
Recommendation: Always match the gutter colour to the fascia colour. Kalsi Plastics’ rainwater systems are available in colours that match the roofline range precisely — because both are manufactured from the same compound.
Rule 2: Soffit Can Contrast
The soffit sits underneath the overhang — it is only visible when looking upward or at close range. It does not need to match the fascia. In fact, a contrasting soffit often looks better:
- White soffit reflects light upward, brightening the eaves
- Dark soffit (matching fascia) creates a uniform, slab-like appearance that can look heavy
- White soffit with dark fascia is the winning formula for most properties
Rule 3: Match Bargeboards to Fascia
Bargeboards are the sloping equivalent of the fascia on gable ends. They should always match the fascia colour — a colour change at the junction looks disjointed.
Rule 4: Consider the Windows
The roofline should complement the window frames. If the windows are anthracite grey, grey roofline creates cohesion. If the windows are white, white fascia maintains consistency (though grey can still work as a deliberate contrast).
Rule 5: Coordinate Downpipes and Rainwater Fittings
Downpipes are visible at eye level and trail down the full height of the wall. They should match the guttering colour without exception. A grey gutter with a white downpipe is a common oversight that undermines the entire colour scheme. The same applies to hoppers, shoes, and offset bends — every component in the rainwater system should be ordered in the same colour.
Rule 6: One Range, One Supplier
PVC-U colours vary between manufacturers. “White” from one brand may be slightly different from “white” from another. For perfect colour matching, source fascia, soffit, guttering, and all trims from the same manufacturer. Kalsi Plastics’ roofline and rainwater systems are manufactured from the same compound, ensuring exact colour consistency across every component.

The Two-Tone Approach: Why It Works
The two-tone roofline (dark fascia/gutter + white soffit) is not just a fashion trend — it works for practical and visual reasons:
Visual Separation
A dark fascia creates a strong horizontal line at the roof edge, anchoring the building visually. The white soffit provides a lighter transition between the dark roof and the wall below.
Light Reflection
White soffit reflects ambient light upward and outward, making the eaves feel more open. All-dark soffits can make the overhang feel cave-like, especially on deep overhangs.
Practical Maintenance
White soffit is less visible from ground level (it faces downward), so dirt accumulation is less noticeable than it would be on a forward-facing white fascia. The dark fascia hides surface grime on the most visible surface.
Ventilation Visibility
Vented soffit boards are critical for roof ventilation under Building Regulations. White vented soffit is widely available and the ventilation slots are less conspicuous against a lighter background, maintaining a clean appearance while meeting regulatory requirements.
Common Colour Mistakes
1. All White When Windows Are Grey
White roofline with grey windows creates an uncoordinated appearance. If you have recently fitted grey windows, match the fascia and guttering to grey when the roofline is next replaced.
2. Brown Gutters on Red Brick
Brown and red compete — the similar warm tones create a muddy, undefined roofline. Black or grey provides clearer contrast.
3. Mixing Brands
A “white” gutter from one manufacturer against a “white” fascia from another can show a visible colour difference, especially in direct sunlight. Use one manufacturer throughout.
4. Forgetting the Downpipes
Downpipes should match the guttering colour. A grey gutter with a white downpipe trailing down the wall looks like a mistake — and it is visible at eye level for visitors approaching the front door.
5. Ignoring the Back of the House
Many homeowners choose a premium colour for the front but go with standard white on the rear to save money. This works for rear-only changes, but if the property is visible from the side (corner plot, open-plan estate), the colour change is noticeable and looks odd.
6. Overlooking Window Trims and Cladding
If you are replacing the roofline, consider whether window trims and gable-end cladding should also be updated to match the new colour scheme. A grey fascia with old white window surrounds creates a half-finished appearance.
Sampling Before Committing
Colour on a screen or in a catalogue can differ from the real product. Before committing to a full-house colour scheme:
- Request physical colour samples from the manufacturer or your builders’ merchant
- Hold samples against the wall at the property — in natural daylight, not indoor lighting
- Check at different times of day — colour appearance changes dramatically between morning sun, midday, and overcast conditions
- Look from the street — stand at the distance a passer-by would see the property; subtle colour differences are invisible from 10+ metres
- Photograph the sample against the property — a quick phone photo helps you compare options side by side later
Kalsi Plastics can supply colour swatches and sample offcuts through our stockists. Contact your local builders’ merchant or visit our colour range page for the full palette.
Frequently Asked Questions
Should fascia and gutters match?
Yes, matching the fascia and gutter colour is the standard recommendation for a coordinated, professional appearance. They sit directly next to each other and a colour mismatch is the most noticeable roofline inconsistency.
Can I have a different colour soffit to the fascia?
Yes — and it is the most popular approach. White soffit with a dark fascia (anthracite grey, black) creates a two-tone effect that is the leading roofline trend in 2026. The white soffit reflects light and brightens the eaves while the dark fascia defines the roof edge.
What is the most popular roofline colour combination?
Anthracite grey fascia and guttering with white soffit is the most popular combination in 2026. It coordinates with grey windows (the dominant window colour on new builds and replacements) and gives a modern, architectural finish that works on most UK property types.
Should bargeboards match the fascia?
Yes. Bargeboards meet the fascia at the eaves corner, and a colour mismatch at this junction looks untidy. Keep bargeboards the same colour as the fascia for visual consistency along the entire roofline.
Can I mix anthracite grey fascia with black guttering?
You can, and it works on some properties, but it is not the cleanest combination. Anthracite grey and black are close enough in tone that the difference reads as a mismatch rather than a deliberate contrast. For the best result, match exactly — grey with grey, or black with black.
Does anthracite grey roofline fade over time?
Quality PVC-U with through-colour pigmentation and UV stabilisation resists fading for the life of the product (30+ years). Cheaper boards without proper UV stabilisation may fade or chalky within 5–10 years. This is why manufacturer choice matters — Kalsi Plastics boards are manufactured with full UV protection as standard.
