Why Is Everyone in Brighton & Hove Swapping to Anthracite Grey Fascia Boards?

I’ve been standing on roofs across Brighton, Hove, and Worthing for over 18 years, and I can tell you that anthracite grey (RAL 7016) has completely taken over Sussex. Homeowners want that sleek, modern finish to contrast with red brick, rendering, or modern aluminum windows. It looks fantastic when done right—it gives an instant facelift to a property.

But here is my honest opinion after almost two decades in the trade: a dark roofline looks brilliant on day one, but if it isn’t fitted properly, heat expansion and sea salt air in our coastal climate will ruin it faster than you think.

Can You DIY Paint Old uPVC or Timber Boards Anthracite Grey?

I get asked this on job sites every single month: “Jan, can I just grab a tin of anthracite grey spray paint or exterior gloss and paint over my old white uPVC or rotting wooden fascias?”

Here is my brutally honest answer: You can, but it’s a temporary band-aid that will look terrible within 12 to 18 months.

If you are desperate for a quick DIY fix because you’re selling the house next week, sure, you can scrub down the old white uPVC, key it with sandpaper, use an expensive exterior plastic primer, and brush on specialist paint. It’ll cost you £50 in materials and a weekend on a ladder.

The hard truth? Dark grey paint absorbs sunlight aggressively. The expansion and contraction of the underlying board under the summer sun will crack that paint layer within a season or two. Moisture gets underneath, it peels, and you end up with a patchy, flaking eyesore. Worse still, if you paint over rotten wooden fascias, you are simply trapping wet rot inside the timber, which eventually destroys your rafter feet and leads to water ingress into your roof space. If water is already creeping into your home, you shouldn’t mess around with DIY cosmetic fixes—you need an emergency roof leak repair to stop the damage before fitting new fascias.

The Heat Trap: Why Anthracite Grey uPVC Needs Special Installation Rules

White uPVC reflects sunlight; dark grey uPVC absorbs it. On a blazing July afternoon in Hove, an anthracite grey fascia board can easily reach temperatures over 60°C. When uPVC gets that hot, it expands significantly more than standard white cladding.

If a roofer installs dark grey fascia boards tightly against each other without leaving proper expansion gaps (at least 5mm to 10mm at the joints), the boards will expand, butt heads, and warp or pop off the wall. I’ve fixed dozens of DIY jobs and cheap installations where the boards literally bowed outward like bananas because nobody allowed for thermal movement.

When I carry out a full uPVC fascia replacement service in Brighton and Sussex, I don’t just cap over old wood. I strip the rotten material back to the rafters, install full-replacement 18mm heavy-duty load-bearing anthracite boards, use stainless steel grey-topped pins, and engineer precise expansion joints covered with color-matched joint trims.

Matching Anthracite Fascias with Gutters and Flat Roofs

If you are fitting anthracite fascia boards, don’t leave your old discolored white or faded black gutters sitting on top of them. It ruins the whole look. I always recommend fitting deep-flow anthracite grey or black seamless rain systems at the same time. If your drainage isn’t set up properly, water will pool and overflow right behind your pristine fascia boards. You can read more about how I handle guttering setups on my guttering and downpipe installation page.

Also, if you are updating your roofline alongside a porch, dormer, or garage flat roof replacement, combining anthracite grey trims with dark EPDM rubber or GRP fiberglass creates a clean, fully watertight seal that lasts 30+ years.
